Motorized Pulley 220M & 220H, Ø 8.50 in. (216 mm)

Rulmeca Motorized Pulleys: a new name with deep rootsThe Rulmeca Motorized Pulleys presentedin this catalogue have a long historyto tell. It goes back to the 1950’s, whenthe product was developed in Germanyand Denmark.Eventually, through a merging processthe German Förder und AntriebstechnikAschersleben GmbH and the DanishJohn Kirkegaard Maskinfabrik A/Sbecame partners in the Interroll Group.From the early 1990’s the manufacturingof all Interroll’s BULK Motorized Pulleyswere centralized in Aschersleben, Germany.In July 2003 Rulli Rulmeca S.p.A. purchasedthe production facility in Aschersleben,Germany, where Motorized Pulleyshave been developed and producedfor almost half a century, along with theentire BULK Business Unit.Today this plant, renamed RulmecaFAA GmbH, will continue the JOKItradition for quality and reliability underthe Rulmeca brand.Thanks to this long history Rulmeca is avery experienced manufacturer of BULKMotorized Pulleys, offering the world’slargest product range.www.rulmecacorp.comwww.precismeca.ab.cawww.rulmecacorp.com 2TC101: 03/07

Features and Benefits of Rulmeca Motorized PulleysPurpose-built designThe Rulmeca Motorized Pulley has beenspecifically designed for belt conveyors.Hermetically SealedThe motor, gearbox and bearings arehermetically sealed inside a steel shell.Therefore they are unlikely to fail due toharmful environmental conditions suchas water, dust, grit, chemicals, grease,oil, etc.Space saving designBecause the drive unit and the bearingsare mounted inside the Motorized Pulleyshell, it requires much less room than anexposed drive. No need for costly extraslike chains, v-belts, couplings, bearings,support structure and special guarding.SafetyThe Rulmeca Motorized Pulley is one ofthe safest drives available because themotor is completely enclosed and theexternal shafts are always stationary.The only moving external parts are theMotorized Pulley shell and bearing housings.Low purchasing and installation costThe Rulmeca Motorized Pulley is quiteoften less expensive than exposeddrives because it has fewer parts. Thereforeless conveyor design time and partspurchasing costs. It is also much quickerand easier to install - certainly less thana quarter of the time taken to fit anexposed system.Low maintenance costThe end user also benefits from the RulmecaMotorized Pulley, because itrequires no maintenance other than therecommended oil change every 10,000operating hours and oil seal changeevery 30,000 operating hours. In otherwords, almost 5 years between oilchanges based on an 8-hour/day workingweek. Synthetic oil can be specifiedto extend the oil service life up to 30,000operating hours.EfficiencyThe Rulmeca Motorized Pulley usuallyhas a much higher efficiency from electricalmotor to shell (Pulley face) thanexposed drives, because it has fewerfrictional losses. Therefore, efficienciesof up to 97% can be achieved.CleanlinessBecause the Rulmeca Motorized Pulleyis hermetically sealed it cannot contaminateany conveying materials such asfood, electrical components, plastics andother materials that must be kept perfectlyclean during handling.Aesthetic appearanceIf installed correctly the Rulmeca MotorizedPulley always looks good. Due to itscompact size and smooth lines, theMotorized Pulley is out of sight, because itis hidden within the conveyor frame.Thermal protectionAll three phase Rulmeca Motorized Pulleysare protected by our thermal protectionswitches. These heat-sensitiveswitches are built into the motor windingsto protect the motor from overheating.The thermal protectors must be connectedto a normally closed control circuitin order to protect the motor.Weight saving and distributionThe Rulmeca Motorized Pulley is oftenlighter than exposed drives. It is possibleto reduce the weight and cost of theconveyor structure, because the conveyordrive weight is evenly distributed withinthe conveyor frame.Variable frequency driveAll Rulmeca Motorized Pulleys with 3phase motors are easily controlled byvariable frequency drives working in the12 Hz to 66 Hz frequency range. SeeTechnical Precautions in the catalogue.Fewer partsA Rulmeca Motorized Pulley consists ofthe Motorized Pulley and two fixingbrackets! Exposed drives can require upto eight or more separate components,most of which have to be purchasedfrom different suppliers or custom manufactured.Low noiseThanks to the totally sealed enclosureand high quality gears the RulmecaMotorized Pulley runs almost at a whisper– a very important fact in today’smodern factory environments.The Rulmeca Motorized Pulley – theideal drive unit for conveyors “Fit itand forget it!”www.rulmecacorp.com 3TC101: 03/07

Motorized PulleysDual Drive ConceptBucket Wheel Reclaimer for taconite pelletsLocated in “center drive position” beneath a 4,000 TPH bucket wheelreclaimer tail conveyor at Lake Superior taconite ship loading facility, twomodel 800H 120 HP Motorized Pulleys drive discharge belt at 768 FPM.Since the 2004 reclaimer upgrade, each Motorized Pulley is powered by460V/3ph/60 Hz directly by the on-board diesel electric generator. Motorsynchronization was not necessary on either this reclaimer or its two sistermachines at the terminal.Technical Precaution: Always mount motorized pulley with “UP” directionoriented according to installation instructions.Reversing Shuttle Conveyor for crushed graniteOne of two 31.5” diameter 50 HP Motorized Pulleys, one on north end andone on south end, driving reversing shuttle conveyor at Lafarge’s Mountsorrelgranite quarry since 1998. Photo shows stone discharging from 600FPM belt at 2,500 TPH. Changing from a “single drive” to a “dual drive”arrangement can reduce slack-side belt tension (T 2) to 20%. This willreduce maximum belt tension (T 1) and can significantly extend conveyor beltlife because it provides 360 degrees of belt wrap around pulleys (180degrees per Motorized Pulley), without the use of “dirty side” snub pulleys.Technical Precaution: When using Motorized Pulleys in reversing application,always bring conveyor to complete stop before starting belt in oppositedirection (see page 84-85.)Suspended Construction Conveyor for wet concreteOne of four 150 foot long “dual drive” conveyors suspended from constructioncranes to pour wet concrete during Sesam River Dam construction inSoutheast Asia. During the five year project each conveyor was driven atthe head and tail by a model 800H 50 HP Rulmeca Motorized Pulley.Overland Conveyor for graniteOne of two 150 HP Rulmeca Motorized Pulleys on two mile long overlandconveyor at Lafarge’s Mountsorrel Quarry in “center drive position.” The twoMotorized Pulleys are driven by synchronized ABB variable frequencydrives (VFDs), transferring granite on the 48” wide belt at various rates upto 2,000 TPH. The VFDs: (1.) provide a “soft start” feature, (2.) enable thetwo drives to “talk” and keep rotor speeds synchronized, and (3.) conservepower by linking to load sensors and optimizing belt speed according tomeasured conveyor throughput.Technical Precaution: When using a VFD always restrict frequencies tobetween 12 Hz to 66 Hz and install a filter on the VFD output if it is locatedmore than 30 feet from the Motorized Pulley (see page 86.)www.rulmecacorp.com 6TC101: 03/07

Motorized PulleysCompact DrivesTriple Cross BeltsThree 12.64” diameter 5.5 HP motorized pulleys simplify design, installation,and maintenance of cross belt drives in this mobile double screen plant inSpokane, Washington. Mobile screen plant designers frequently use motorizedpulleys to drive cross belts because of the severe space restrictions inthe drive nest.Self-cleaning Magnetic SeparatorA 12.64” diameter 4 HP motorized pulley drives cleated belt surroundingelectromagnet on portable crushing/screening system at this Louisiana C &D debris recycling facility. Also in service in Europe, this Austrian-designedrig also features motorized pulleys on screen feed, cross belts, and dischargebelts.Technical Precaution: When using electromagnets near motorized pulleysalways direct magnetic flux away from motorized pulley so that flux fielddoes not interfere with motor. It is NOT necessary to use stainless steel pulleyshells in these applications.Double Triple Cross BeltsThis Canadian mobile screen features four 12.64” diameter 5.5 HP and two12.64” diameter 3 HP cross belt drives. Note the absence of separate motorand gearbox mounting platforms and expanded metal guarding—all eliminatedthrough the use of motorized pulleys. Photo taken in Ontario limestonequarry in 1994.Glass Recycling ConveyorThe 12.64” diameter 5.5 HP motorized pulley used at this cullet conveyortransfer point minimizes space requirements. It also offers increased drivereliability (due to its hermetic seals) in the highly abrasive atmosphere.Photo was taken at the Raleigh, North Carolina glass recycling center in1994.Technical Precaution: When using optional regreasable seals on motorizedpulleys in abrasive applications periodically purge grease through seals toprevent grit-laden grease from causing premature oil seal wear.www.rulmecacorp.com 29TC101: 03/07

Motorized Pulley 320L, 320M & 320H, Ø 12.64 in. (321 mm)Our 12.64” diameter Motorized Pulleyrange offers three differentperformance levels for BULKapplications:- L for Light duty- M for Medium duty- H for Heavy dutyIt is important to note the productdifferences and choose theappropriate pulley based onestimated belt tension (radial load.)See page 78. The actual radial loadmust be less than the maximumallowable radial load shown in thiscatalog.Be aware of increased belttensions required to drive multi-plythick heavy belts and/or larger beltwidths.If the 12.64” diameter model is notstrong enough to resist estimatedbelt tension, then select 15.91”diameter model.L for Light duty320L is designed for regular andcontinuous operating conditions. It isadvisable to rubber lag these pulleysto grip the belt and limit belt tension.Typical applications are portableconveyors and cross belts in mobilecrushing and screening equipment.320L should not be used for lowspeed high torque feeder conveyors.320L uses motor and gearbox from220M.M for Medium dutyThe internal parts of 320M aredesigned for tough and irregularoperating conditions (e.g. crushing &screening applications, asphalt,cement, and concrete plants.)H for Heavy dutyA solid 3-stage gearbox, largershafts, and stronger bearings enablethe 320H to provide low speed athigh torque and handle irregularloadings in harsh operatingconditions.STANDARD SPECIFICATIONof Motorized Pulley• Crowned mild steel 12.64” diametersteel shell treated with anti-rust wax• Powder coated cast iron bearing housings• Mild steel shafts treated with anti-rustwax• Shaft sealing system – degree of protectionIP66/67 (EN60034-5.)

Motorized PulleysTail DrivesTaconite Ship Loading Terminal (Michigan—USA)DEMAG crawler-mounted bucket wheel reclaimer handles taconite pellets at5,000 TPH on 72” wide boom and tail belts at this Escanaba, Michigan facility.Terminal operator replaced both original Kufnagel conveyor drives with40” diameter Rulmeca Motorized Pulleys in 1985 after 13 years of service.Photo shows tail-mounted 200 HP drive pulley for discharge conveyor.Trap Rock Quarry (New York—USA)Allis Mineral Systems delivered this 850 TPH recirculating crushing andscreening plant in 1994. The tail-mounted 15.75” diameter 15 HP MotorizedPulley drives the 36” wide screen feed belt, in tandem with an identicalhead-mounted drive, at 384 fpm. Motorized Pulleys enabled designers toadhere to the 12’ maximum allowable US highway clearance width. Taildrive is mounted in a “Sliding Pedestal” mechanical belt take-up.Technical Precaution: When mounting a motorized pulley in a screw takeupalways make sure that pulley centerline is perpendicular to belt centerlineto avoid overstressing internal bearings.Marl Pit at Cement Plant (South Carolina—USA)FAM delivered this crawler-mounted bucket wheel reclaimer in 2002 toexcavate marl from a pit adjacent to the producer’s cement plant nearCharleston, South Carolina. It uses tail-mounted 31.5” diameter 100 HPMotorized Pulleys to drive the 54” wide boom and tail conveyor belts at 600fpm. Externally mounted brakes prevent material from “rolling backwards”when conveyors are stopped because both conveyors can articulate to a 16ºmaximum inclination.Granite Quarry (Connecticut—USA)Built in 2003 by RR Equipment, this mobile recirculating crushing andscreening rig uses a tail-mounted 15 HP 15.75” diameter Motorized Pulleyto drive the 36” wide 300 TPH 58’ long screen feed conveyor. Note that useof slender “Telescoping” mechanical belt take-up allows compact and lightweightstructure. This plant adheres to the maximum US highway clearancerequirements of 12’-0” wide by 13’-6” high.Technical Precaution: When mounting a motorized pulley in a screw takeupalways make sure that pulley centerline is perpendicular to belt centerlineto avoid overstressing internal bearings.www.rulmecacorp.com 39TC101: 03/07

Motorized Pulley 400L, 400M & 400H, Ø 15.91 in. (404 mm)Our 15.91” diameter Motorized Pulleyrange offers three differentperformance levels for BULKapplications:- L for Light duty- M for Medium duty- H for Heavy dutyIt is important to note the productdifferences and choose theappropriate pulley based onestimated belt tension (radial load.)See page 78. The actual radial loadmust be less than the maximumallowable radial load shown in thiscatalog.Be aware of increased belttensions required to drive multi-plythick heavy belts and/or larger beltwidths.If the 15.91” diameter model is notstrong enough to resist estimatedbelt tension, then select 19.72”diameter model.L for Light duty400L is designed for regular andcontinuous operating conditions. Itis advisable to rubber lag thesepulleys to grip the belt and limit belttension. A popular application is selfcleaningmagnetic separators. 400Luses motor and gearbox from 320M.M for Medium duty400M is designed for tough andirregular operating conditions. 400Mis typically used in heavy mobilecrushing & screening applications aswell as in crushed stone, ore,cement, steel, and fertilizer handling.H for Heavy dutyA solid 3-stage gearbox enables the400H to provide low speed at hightorque and handle irregular loadingsin harsh operating conditions.STANDARD SPECIFICATIONof Motorized Pulley• Crowned mild steel 15.91” diameter steelshell painted yellow at a minimum thicknessof 2.4 mils• Bolted powder coated cast iron bearinghousings and covers, all painted yellowat a minimum thickness of 2.4 mils• Mild steel shafts treated w/anti-rust wax• Shaft sealing system - degree of protectionIP66/67 (EN60034-5.)

Motorized PulleysHopper Feeder DrivesLimestone Quarry (Georgia—USA)Two 15.75” diameter 5.5 HP Motorized Pulleys were installed 1994 to automatically“choke feed” tertiary gyratory crushers, working in combinationwith variable frequency drives (VFD) and ultrasonic sensors. Each pulleydrives a 36” wide belt at a maximum speed of 120 FPM to transfer 4” minusproduct at 425 TPH.Technical Precaution: When driving motorized pulley with VFD on 460 volt3 phase 60 Hz power supply, always restrict frequencies to allowable frequencyspectrum of 12 to 66 Hz to avoid torque loss and heat build-up. FilterVFD output if VFD is more than 30’ from motorized pulley to avoid resonance-inducedvoltage spikes.Foundry for Railroad Truck Castings (Ohio—USA)Installed at first American Steel Foundries (now Alliance Castings Company)plant in 1980, this 15.75” diameter 10 HP motorized pulley transfers recycledfoundry sand to mold area at 150 TPH. Conveyor makes 30 start/stopsper hour. Ambient environment is hot (>104º F) and contains a high percentageof airborne abrasive particulate. Photo taken in 1993, after 13years of service.Technical Precaution: When installing motorized pulley in hot environment(>104º F), specify optional Class H motor windings and synthetic oil. ContactRulmeca if ambient temperature will exceed 120º F.Taconite Processing Plant (Minnesota—USA)Two limestone feeder belt drives beneath storage silo were converted from20-year-old DC motors to AC-powered motorized pulleys in 1995. An ABBVFD drives each 19.72” diameter 5.5 HP motorized pulley to a maximum of120 FPM. Conversion enabled plant operator to eliminate exposed motorsand gearboxes and replace SCRs, relays, and timer banks with VFDs incontrol panel.Technical Precaution: When driving motorized pulley with VFD on 460 volt3 phase 60 Hz power supply, always restrict frequencies to allowable frequencyspectrum of 12 to 66 Hz to avoid torque loss and heat build-up. FilterVFD output if VFD is more than 30’ from motorized pulley to avoid resonance-inducedvoltage spikes.Electric Power Plant (Connecticut—USA)Designed and built in 1989 by ABB, this refuse derived fuel (RDF) plant usestwo 12’ diameter trommels to separate light burnable trash from landfillmaterial. A 24.80” diameter 30 HP Motorized Pulley drives each steeplyinclined trommel feed conveyor at 300 FPM. Each 100’ long 48” wide feedbelt is fitted with cleats and sidewalls to elevate 250 TPH of refuse at 45ºinclination.Technical Precaution: When using motorized pulley to drive a single directionbelt on an incline use built-in mechanical backstop to prevent materialfrom rolling downhill when belt stops.www.rulmecacorp.com 49TC101: 03/07

Motorized Pulley 500L, 500M & 500H, Ø 19.72 in. (501 mm)Our 19.72” diameter Motorized Pulleyrange offers three differentperformance levels for BULKapplications:- L for Light duty- M for Medium duty- H for Heavy dutyIt is important to notice the productdifferences and choose theappropriate pulley based onestimated belt tension (radial load.)See page 78. The actual radial loadmust be less than the maximumallowable radial load shown in thiscatalog.Be aware of increased belttensions required to drive multi-plythick heavy belts and/or larger beltwidths.If the 19.72” diameter model is notstrong enough to resist estimatedbelt tension, then select 24.80”diameter model.L for Light duty500L is designed for tough andirregular operating conditions. 500Lis typically used in heavy mobilecrushing & screening applications aswell as in crushed stone, ore, cement,steel, and fertilizer handling. 500Luses motor and gearbox from 400M.Note that 500L outer dimensions donot match 500H (Former modelsTM500 and TM501).M for Medium dutyA solid 3-stage gearbox enables the500M to provide low speed at hightorque and handle irregular loadingsin harsh operating conditions. 500Muses motor and gearbox from 400H.Note that 500M outer dimensions donot match 500H (Former modelsTM500 and TM501).H for Heavy duty500H has strongest internalcomponents in this diameter withgearbox, shaft, and bearingsdesigned for tough, irregular, andextreme operating conditions.STANDARD SPECIFICATIONof Motorized Pulley• Crowned mild steel 19.72” diametersteel shell painted yellow at a minimumthickness of 2.4 mils• Bolted powder coated cast iron bearinghousings and covers, all painted yellowat a minimum thickness of 2.4 mils• Mild steel shafts• Shaft sealing system - degree of protectionIP66/67 (EN60034-5.)

Motorized PulleysBucket Wheel Excavators & ReclaimersFAM Excavator (Marl Pit in South Carolina—USA)FAM designed and built this 1,000 TPH excavator for an internationalcement producer in 2002. The 50’ long boom conveyor and 100’ long dischargeconveyor each use a 31.5” diameter 100 HP Motorized Pulley todrive a 54” wide belt at 600 FPM. FAM has been using Rulmeca MotorizedPulleys as excavator belt drives for more than 30 years. Photo was takenduring machine commissioning.Technical Precaution: When using a motorized pulley on an articulatingconveyor that inclines up and down use a brake to prevent material fromrolling “downhill” when conveyor stops. External brake shaft option is availablefrom Rulmeca.Mechanical Excavator Reclaimer (Allouez Dock—Superior, Wisconsin)Photo shows one of three 40 year old bucket wheel reclaimers upgraded atrail to ship transfer facility by BNSF. In 2004 tandem 120 HP RulmecaMotorized Pulleys (in a “Nested Dual Drive”) replaced original 200 HP tailconveyor drive and a single 120 HP Motorized Pulley replaced originalboom conveyor drive on machine shown. Only minor structural modificationswere required. On-board diesel engines were also replaced duringupgrade to provide 460V/3ph/60 Hz power supply to Motorized Pulleys.Each of three bucket wheel reclaimers now handles 4,000 TPH of taconitepellets on 54” wide belts at a speed of 768 FPM.Technical Precaution: When using labyrinth seals periodically purge greasethrough seals to prevent grease-born grit from attacking rubber oil seals.German Reclaimer (Taconite Mine in Vitoria—Brazil)Brazilian taconite processing plant operator replaced the 1963-vintagemotorized pulleys on boom and discharge conveyor belts with new Rulmeca31.5” diameter 100 HP Motorized Pulleys in 2001. Because of the abrasivenature of taconite ore dust, the operator used labyrinth seal option tomaximize oil seal life.Technical Precaution: When using labyrinth seals periodically purge greasethrough seals to prevent grease-born grit from attacking rubber oil seals.DEMAG Reclaimer (Taconite Ship Loading Terminal in Michigan—USA)Demag designed and built this 5,000 TPH reclaimer in 1967. Terminal operatorreplaced original motorized pulleys with 40” diameter Rulmeca MotorizedPulleys in 1985. A 150 HP Motorized Pulley drives the 60’ long 72” wideboom belt at 600 FPM. A 200 HP motorized pulley drives the 75’ long 72”wide discharge conveyor at 600 FPM. Since the 1985 conversion RulmecaMotorized Pulleys have moved more than 150 million tons of taconite pelletsthrough the reclaimer.Technical Note: Rulmeca supplies parts and service for 40” diameter MotorizedPulleys up to 200 HP. However, the current portfolio does not includethis model. Research and development aimed at producing Motorized Pulleysmore powerful than 180 HP is currently underway.www.rulmecacorp.com 59TC101: 03/07

Motorized Pulley 630M & 630H, Ø 24.80 in. (630 mm)Our 24.80” diameter Motorized Pulleyrange offers two differentperformance levels for BULKapplications:- M for Medium duty- H for Heavy dutyIt is important to note the productdifferences and choose theappropriate pulley based onestimated belt tension (radial load.)See page 78. The actual radial loadmust be less than the maximumallowable radial load shown in thiscatalog.Be aware of increased belttensions required to drive multi-plythick heavy belts and/or larger beltwidths.If the 24.80” diameter model is notstrong enough to resist estimatedbelt tension, then select 31.50”diameter model.M for Medium dutyA solid 2-stage gearbox enables the630M to handle irregular loadings inharsh operating conditions. 630Muses motor and gearbox from 500H.Note that 630M outer dimensions donot match 630HH for Heavy duty630H has stronger internalcomponents with gearbox, shaft, andbearings designed for tough,irregular, and extreme operatingconditions.STANDARD SPECIFICATIONof Motorized Pulley• Crowned mild steel 24.80” diametersteel shell painted yellow at a minimumthickness of 2.4 mils• Bolted powder coated cast iron bearinghousings and covers, all painted yellowat a minimum thickness of 2.4 mils• Mild steel shafts• Shaft sealing system - degree of protectionIP66/67 (EN60034-5.)

Motorized PulleysMechanical BackstopsSand and Gravel Pit (Texas—USA)Installed in 1994 this 12.64” diameter 7.5 HP Motorized Pulley drives the 24”wide inclined “overs belt” at 300 FPM. This conveyor stacks large unusablerocks scalped from the product stream by the primary screen at the activeface in the pit. The Motorized Pulley’s built-in mechanical backstop protectspersonnel and equipment from product “roll back” when it is necessary tostop a fully loaded belt.Technical Precaution: It is essential that the identity of each of the three phasesof the power supply be determined before attaching power supply wires tothe pulley to prevent the motor from driving against the backstop. The identityof each of the three phases of the motor is clearly labeled.Mechanical Backstop Exploded ViewRulmeca’s mechanical backstops are built into the Motorized Pulley to limitpulley rotation to one direction (either clockwise or counterclockwise.) Thebackstop’s keyed inner race is fixed to the motor rotor and the outer race isbolted to the motor stator frame.Fixing the backstop to the motor rotor shaft, on the input side of the internalgearbox, yields two advantages: (1.) the backstop has all of the mechanicaladvantage, which can be as high as 100:1, and (2.) it is protected in a hermeticallysealed environment. On the other hand, an exposed backstopcoupled to a live pulley shaft has no mechanical advantage (and must bemuch larger) and is exposed to the environment.Granite Quarry (Virginia—USA)A 20 HP 15.75” diameter Motorized Pulley elevates crushed rock 25 feet at384 FPM on the 30” wide fixed transfer conveyor at this plant (center ofphoto.) A “clockwise backstop” prevents run back of the loaded belt beltwhen power supply is off.Technical Precaution: Direction of proper pulley rotation is indicated by analuminum arrow or plastic sticker fastened to the end housing on the terminalbox (or power cord) side of the pulley. Clockwise and counterclockwise backstopsare available. Pulley rotation is specified from the point of view of aperson looking at the pulley from the terminal box (or power cord) side of thepulley. Rotation direction is to be specified when placing orderMechanical Backstop and Rear Flange DesignDrawing shows Motorized Pulley mechanical backstop (for models 400M -500M) keyed to motor rotor shaft and bolted to motor stator frame. Note thatmechanical backstop option requires an extended rear flange (and largerminimum Roller Length) for certain models.Models 138E - 320L use a one-way motor rotor bearing in a standard motorstator and do not require an extended rear flange. Models 320M - 500M adda backstop to the stator within an extended rear flange, as shown. Models500H - 800H add a backstop to the stator within a standard rear flange.www.rulmecacorp.com 70TC101: 03/07

Motorized PulleysInternal and External BrakesMarl Pit at Cement Plant (South Carolina—USA)Installed by FAM in 2002, this crawler-mounted bucket wheel machine excavatesmarl at a rate of 1,000 TPH. It uses tail-mounted 31.5” diameter 100HP Motorized Pulleys to drive the 54” wide boom and tail conveyor belts at600 fpm. FAM specified Rulmeca Motorized Pulleys with “external brakeshaft option” because both conveyors can articulate +/- 16º and mechanicalbackstops could not be used..” Externally mounted brakes (by others) preventmaterial from “rolling backwards”when conveyors are stopped.Technical Precaution: Control circuit must be designed so that motor andbrake never work against each other. Brake should never be clamped shutwhen motor is on except for “emergency stop.” Motor should never be poweredon (including “jog” command) when the brake is clamped shut.Example of External Brake (South Carolina—USA)Available in models 500H and larger, Rulmeca external brake shaft optionextends motor rotor shaft through hole in non-rotating pulley shaft for attachmentof external brake (by others.) This hydraulically-actuated double-shoebrake (protective cover removed for photograph) prevents conveyor rollback when fully loaded belt is stopped.The external brake option provides one of the two key advantages availablewith the internal brake option. Brake has all of the mechanical advantage ofthe drive (as high as 100:1 ratio) because it is fixed directly to the motor rotorshaft. It is, however, exposed to the environment.Rulmeca Internal BrakeRulmeca internal brake is designed to function primarily as a belt holdingdevice for reversing and/or articulating conveyors. The brake is not intendedto be a conveyor stopping device. The brake’s keyed spline is fixed tothe motor rotor and the brake’s housing is bolted to the motor stator frame.Fixing the brake to the motor rotor shaft, on the input side of the internalgearbox, yields two advantages: (1.) the brake has all of the mechanicaladvantage, which can be as high as 100:1, and (2.) it is protected in a hermeticallysealed environment.Rulmeca Internal Brake/Motor/Gearbox AssemblySpring-loaded electromagnetic brakes are designed to release when power isapplied to the brake coil. This is a “fail safe” feature. They clamp shut whenbrake power is removed (either during normal operation or during an emergencyloss of overall system power.) Photo shows 320H model. Note that thisoption requires additional internal space and larger minimum Roller Length.Technical Precaution: Control circuit for motor and brake must be designed tostop pulley motor before brake clamps shut and start pulley motor after brakeis released. Brakes are DC-powered and supplied with AC to DC rectifiers tobe mounted in a remote panel (by others). Control circuit must be designedto kill motor power in the event of loss of brake power. If this provision is notmade, motor can possibly “power through” clamped brake.www.rulmecacorp.com 71TC101: 03/07

Applications in Special Environmental ConditionsAbrasive, Wet, High HumidityEnvironmentsHermetically sealed carbon steel tubeand end housings with standard paint aresuitable for most bulk applications. However,aggressive environments mayrequire regreasable seals, special finish,or stainless steel. See pages 83 - 85.Articulating ConveyorsElectromagnetic brakes or external brakeshafts for brakes (by others) provide suitablematerial “holdback” capability forarticulating conveyors. Mechanical backstopswill not work in this applicationbecause these conveyors elevate andlower material. See pages 70, 71, 79 &81.Chemical/Corrosive Environmentsaggressive environments may requireregreasable seals, special lagging material,special finish, or stainless steel.

Technical Precautions for Design, Installation and Maintenance1) Actual Belt Speed vs. Nominal Belt Speed:• Two key specifications for each Motorized Pulley are power (HP) and nominal belt speed, as shown on individualspecification pages in this catalog.• Nominal belt speed is a design target, providing consistent choices among all models and powers. For example,a nominal belt speed of 300 fpm is available in most pulley models.• Actual full load belt speed is almost never exactly equal to nominal belt speed.• Actual belt speed is a function of the motor pole number, gear ratio, and load. Therefore, this catalog displaysactual full load belt speed at 60 Hz, as well as nominal belt speed, to assist designers who need more precisebelt speeds.• Note that all belt speeds shown in this catalogue refer to unlagged pulleys because:1. Belt speed for each model is a function of pulley diameter,2. Pulleys are available with and without lagging,3. Lagging changes the pulley diameter, and4. Various lagging thicknesses are available.• Note that each Rulmeca Motorized Pulley for a three-phase power supply uses an asynchronous squirrelcage induction motor with approximately 5% slip. In a no load condition, motor RPM is nearly equal to “synchronousspeed” RPM. The slip rate is dependent on power and design of the motor. Low powered motorshave a lower slip rate than high-powered motors. At full load, the motor RPM is approximately 5% less thansynchronous.• The “actual belt speed” displayed in this catalogue is based on an unlagged pulley running at full load, nominalvoltage (e.g. 460 volts) and 60Hz.• The actual full load belt speed of a lagged pulley running at1. Full load,2. Nominal voltage (e.g. 460 volts),3. 60 Hz– equals the actual full load belt speed specified in this catalogue, times the ratio of the lagged/unlagged pulleydiameters.Example: A 320M Motorized Pulley (with an unlagged pulley diameter of 12.64”) at 5.5 HP and nominal beltspeed of 150 fpm has an actual belt speed of 157 fpm at full load, nominal voltage, and 60 Hz. Ifthis pulley is supplied with 1/4” thick lagging, the lagged pulley’s actual belt speed equals 157 fpmx (13.14”/12.64”) = 163 fpm at full load, nominal voltage, and 60 Hz.• The maximum no load belt speed of this lagged pulley is 5% higher than the full load belt speed (i.e. no loadbelt speed = 163 fpm x 1.05 = 171 fpm.2) Aftermarket Service• Always contact your local authorized Rulmeca service center or distributor for aftermarket service.• Or contact Rulmeca at www.rulmecacorp.com3) Ambient Temperature:• Motorized Pulleys are normally cooled by dissipating heat through contact between the surface of the pulleyand the conveyor belt. It is essential that each pulley have an adequate thermal gradient between the pulley’smotor stator and its ambient operating temperature.• All Motorized Pulleys in this catalog are designed and tested under full load (without rubber lagging) for use ina max. ambient temperature of +104 o F with standard Class F motor. Motorized Pulleys with Class H motorsand synthetic oil are suitable for use in a max. ambient temperature of 120 o F.• For example, a conveyor belt in a facility with an air temperature of +75 o F, carrying processed material at atemperature of +130 o F, will have a Motorized Pulley “ambient temperature” that is significantly higherthan +75 o F. In this example, the actual temperature of the bottom of the belt in the vicinity of the MotorizedPulley will be less than or equal to the material temperature, depending upon parameters such asconveyor length, belt thickness, and belt speed.• For ambient operating conditions lower or higher than allowable ambient temperature (-22 o F to 120 o F), contactRulmeca.• It is possible to use specially designed Motorized Pulleys to perform tasks other than driving standard rubberconveyor belt (e.g. modular plastic belts and v-belts for Motorized Pulley types 138E & 165E.) Please contactwww.rulmecacorp.com 77TC101: 03/07

Technical Precautions for Design, Installation and MaintenanceRulmeca for such applications.• Operating Rulmeca Motorized Pulleys to drive standard conveyor belts outside of the allowable ambient temperaturerange voids product warranty.4) Belt Alignment:• Motorized Pulleys must be installed with pulley shaft perpendicular to belt centerline and parallel to all idlerrollers.• Belt centerline must be straight and parallel to side walls of slider bed (if any) and perpendicular to idler rollersand all pulleys• Belt and/or roller misalignment may cause high friction and overload the conveyor belt drive motor.• Belt misalignment may cause premature wear of pulley lagging.5) Belt Pull:• This catalog specifies “Actual Belt Pull” for each model, power, and speed of pulley. Note that the specifiedactual belt pull allows for a motor and gearbox efficiency loss of 3 to 5%.• Always select the Motorized Pulley power by comparing calculated “Required Belt Pull (Te)” with “Actual BeltPull” as listed in this catalog and not simply on the basis of calculated power (HP).• Required Belt Pull is the sum of all forces required to convey material.6) Belt Tension:• The conveyor belt should never be over-tensioned. It should only be installed with sufficient belt tension toprevent belt slippage.• Anti-slip lagging should be used to keep the radial load as low as possible to drive the belt without slipping .• The maximum allowable radial load of each Motorized Pulley is specified in this catalog. Subjecting the MotorizedPulley to a higher than specified maximum radial load may damage internal components and shortenproduct lifetime and, therefore, voids product warranty.• To check pulley radial load, do a vector summation of the loads on the pulley.• For example, as shown in the diagram,1. Radial load equals T1 + T2.2. T1, tight side tension, equals Belt Pull (Te) plus T2.3. T2, slack side tension, is determined using CEMA standard calculations or DIN 22101 to provide enoughfriction between the pulley and the belt to drive the belt.• Belt type, belt thickness and minimum allowable pulley diameter must be selected according to Belt SupplierRequirements.7) Capacitors (for Single Phase Motors):• Each single phase Motorized Pulley requires an appropriate capacitor. For models 138E and 165E a “Run”capacitor is supplied with the pulley. Detailed information is available upon request. Using other than thespecified Run capacitor may damage the motor and voids product warranty.• The Run capacitor must be permanently connected to the motor, as shown in the connection diagrams.• Rulmeca single phase motors are “permanent split phase motors.” Each motor is supplied with two windings.They are designed so that an appropriately sized capacitor connected to one of the windings will start themotor rotating.• Starting torque is limited to 70% of full running torque.• It is possible to increase starting torque to 100% by adding a second appropriately sized capacitor (Startcapacitor) to the circuit. Note that this circuit must be designed to drop the starting capacitor out of the circuitafter the motor has reached its nominal speed. Contact Rulmeca for more information on how to run singlephase motors using Start and Run capacitors.8) Clearance:• It is necessary to design conveyor frame and all chutes such that structure and/or product jamming againstwww.rulmecacorp.com 78TC101: 03/07

Technical Precautions for Design, Installation and Maintenancethe Motorized Pulley is avoided.• The “non-rotating shaft” feature of Motorized Pulleys offers a higher margin of safety than exposed drives withrotating shafts However, Motorized Pulley end housings, lagging, or tube may be damaged if structure orproduct jams against pulley while it is rotating.9) Electrical Installation:• The equipment manufacturer (OEM) must ensure that the Motorized Pulley is not put into operation before itis– Correctly installed,– Correctly connected to the power supply,– Correctly protected.• A specialist must perform the electrical connection of the Motorized Pulley in accordance with electrical regulations.If in doubt, contact Rulmeca.• A wiring diagram is always supplied with the Motorized Pulley. Always refer to the connection instructions andensure that the motor power and control circuits are properly connected.• A wiring diagram is inserted into the terminal box and into the booklet accompanying each Motorized Pulley.• Standard Rulmeca Motorized Pulleys are delivered with clockwise rotation when viewed from the terminalbox end of the Motorized Pulley.• Always refer to the connection instructions and ensure that the motor is connected as required to the correctpower supply.• Connect system ground wire to grounding screw located in the terminal box.• When using cable options the green/yellow wire must be connected to the system ground wire.10) Electromagnetic Brake:• The spring-loaded electromagnetic brake is intended for use as a conveyor belt holding device and not a conveyorbelt stopping device.• The control circuit for the Motorized Pulley motor and brake must be designed to stop the pulley motor beforebrake clamps shut and start the pulley motor after the brake is released.• Spring-loaded electromagnetic brakes are designed to release when power is applied to the brake coil. Thisis a “fail safe” feature. They clamp shut when brake power is removed (either during normal operation or duringan emergency loss of overall system power.)• Control circuit must be designed so that motor and brake never work against each other. The brake shouldnever be clamped shut when the motor is on except for “emergency stop” condition. The motor should neverbe powered on (including “jog” command) when the brake is clamped shut.• Electromagnetic brakes are DC-powered. They are supplied with AC to DC rectifiers to be mounted in aremote panel (by others). Rectifiers must be fuse-protected.• Motor control circuit must be designed to kill motor power in the event of loss of brake power. If this safetyprovision is not made, it is possible for pulley motor to be “powered through” a clamped brake, burning brakeand/or motor.• A wiring diagram is supplied with every Motorized Pulley. Always ensure that motor and brake power and controlcircuits are connected according to instructions. Wiring diagrams are available separately, at any time,upon request.• For rectifier connection and protection instructions, refer to rectifier data sheet supplied with Motorized Pulley.• Neglecting these instructions could cause damage to the motor and/or brake and voids product warranty.11) High Duty Cycle:• Rulmeca Motorized Pulleys are designed to operate either continuously or intermittently. Page 72 giveseach standard model’s maximum allowable start/stop duty cycle for intermittent operation. OperatingMotorized Pulley above this maximum could cause motor and/or gearbox damage and voids product warranty.• Optional Motorized Pulley designs are available to operate at higher duty cycles working with soft start devicesor appropriately programmed Variable Frequency Drives. Contact Rulmeca before designing a system tooperate at a duty cycle higher than specified in this catalog.• Note that a conveyor control system that incorporates a “jog” command should be timed to restrict the numberof jogs to the maximum allowable start/stop duty cycle for each pulley model.www.rulmecacorp.com 79TC101: 03/07

Check with belting supplier if belt/lagging material compatibility could be aproblem.• Adequate Motorized Pulley heat dissipation is necessary. Lagging thickness and width greatly effectpulley heat dissipation characteristics.www.rulmecacorp.com 80TC101: 03/07

Technical Precautions for Design, Installation and Maintenance• As shown in Lagging Limitations table above, certain power and belt speed combinations require that rubber laggingbe restricted to the outer thirds of the pulley face to improve heat dissipation. Each “partially lagged” pulleyhas a thick steel shell in the center (unlagged) third of the pulley face.• Contact Rulmeca before applying any lagging to pulley surface to obtain thickness and width specifications andmaintain Motorized Pulley warranty coverage.• Lagging material is a wear item and should be replaced when it wears out. Service life depends upon the application.Product warranty does not include lagging wear.• At any time all Rulmeca Motorized Pulleys shown in this catalog must be fitted with a conveyor belt to preventoverheating.Motorized Pulleys fitted without a belt must be referred to Rulmeca.14) Mechanical Backstops:• Motorized Pulleys fitted with mechanical backstops are used on inclined conveyors to prevent run back of theloaded belt when power supply is off.• The backstop is built into the Motorized Pulley and is mounted on the rotor shaft.• If pulley is supplied with optional mechanical backstop, direction of proper rotation of pulley is indicated by analuminum arrow or plastic sticker fastened to the end housing on the terminal box (or power cord) side of thepulley. Clockwise and counterclockwise backstops are available.• Rotation direction is to be specified when placing the order.• Pulley rotation is specified from the point of view of a person looking at the pulley from the terminal box (orpower cord) side of the pulley.• It is essential that the identity of each of the three phases of the power supply be determined before attachingpower supply wires to the pulley to prevent the motor from driving against the backstop. The identity of eachof the three phases of the motor is clearly labeled on the terminal board, terminal strip, or wires (in power cordtype).• Driving the motor against the mechanical backstop may damage motor and/or backstop and voids productwarranty.15) Motor Current Overload and Overcurrent Protection:• Motor control system must include protection against operating pulley motors in excess of Full Load Amperage(FLA.). The control system should also include protection against voltage spikes and excessive joggingof motors. Failing to provide adequate current overload and over current protection could stress the motorand voids product warranty.• Electrical connection diagrams for many models are included in this catalog. Connection diagrams for all othermodels are available upon request.• FLA data is available for all motors upon request. FLA data is also supplied on motor label for each Motorized Pulley.• Electrical power, control, and protection for Motorized Pulleys must adhere to all pertinent regulations.16) Motor Thermal Protection:• All Motorized Pulley motors are supplied with built-in thermal protection. Protectionconsists of heat-sensitive, bi-metallic switches built into each motor phase winding. The switches are designedto open if motor temperature elevates to an inappropriately high level. Whether insulation class “F” or “H”, ourstandard bi-metallic switch– has a maximum current limit of 2.5 amps at 230 volts.• These switches must be connected to a normally closed control circuit (in series with a magnetic coil/relaydevice and contactor) in order to validate product warranty.• A motor control circuit should kill motor power if thermal switch opens. Thermal switches will automaticallyclose as motor cools. Cooling times vary with pulley model, power, and size. However, 30 to 60 minutes iscommon with most motors in an ambient temperature of 70° F.www.rulmecacorp.com 81TC101: 03/07

Technical Precautions for Design, Installation and Maintenance17) Motorized Pulley Mounting Orientation:• Before installing the Motorized Pulley, ensure that the data plate information agrees with yourspecification.• Rulmeca Motorized Pulleys should always be mounted so that the pulley shafts are1. Horizontal,2. Parallel to idler rollers, and3. Perpendicular to the conveyor belt centerline.• Motorized Pulleys are positioned such that the mounting brackets are located parallel or perpendicular to theconveyor frame. The cable entry of the terminal box should be located downward or 90 degrees from downward.• For Motorized Pulley types 138E to 500M “UP” is indicated with the word “UP” stamped on the pulley shaft.• Models 138E - 500M are to be mounted as shown on the sketch below.• Models 500H - 800H are to be mounted as shown on the sketch below.• In case of a non-horizontal installation, of more than +/-5 degrees, consult Rulmeca.• Installation and mounting of the Motorized Pulley in a position other than those describedabove could cause severe product damage and voids product warranty.• 18) Mounting Brackets:• Use the correct Rulmeca mounting brackets matching the respective types of Motorized Pulleys as listed in thiscatalog.• Note that it is physically possible, but not permissible, to interchange mounting brackets between models.Mounting brackets designed for smaller diameters or lower-powered pulleys may not be used for larger diametersor higher-powered pulleys.• Mounting brackets must be mounted to frame such that belt pull is resisted by the shoulder or base of the mount-www.rulmecacorp.com 82TC101: 03/07

Technical Precautions for Design, Installation and Maintenanceing bracket. Motorized Pulleys types 138E to 500M have a top shaft retaining plate. This plate is not designedto resist belt pull.• The designer must select appropriate mounting bolts to resist belt forces and/or the weight of the pulley dependingon the mounting position of the Pulley.• All types of mounting brackets must be fully supported by and fastened to the conveyor frame such that theshafts ends do not deform. Shaft ends must always be fully supported by the brackets.• Where solid mounting brackets type AL and ALO are used, the brackets must be assembled close to theshoulder of the round shaft. This is to ensure that the Motorized Pulley has no axial clearance.• The AL type of bracket is fitted with one or two keys depending on load.• Keys must be securely fixed and checked regularly and locked if necessary.• Mounting brackets should be fitted such that they are in contact with the shoulder of each shaft. This will:1. Eliminate Motorized Pulley axial play between mounting brackets.2. Keep shaft deflection to a minimum.• In noise-sensitive areas, the designer should use heavier gauge support structure and appropriate vibrationisolating material, as necessary.• When Rulmeca Motorized Pulley mounting brackets are not used, it is essential that:1. The mounting equipment supports at least 80% of the shaft flats.2. The clearance between each shaft flat shoulder and its support is less than 0.030 inches.• A Motorized Pulley with frequent reversible operations or many start/stops should be mounted with no axialclearance between the shaft flat and the brackets.• Failing to follow these precautions could cause pulley and/or mounting bracket damage and voids product warranty.19) Non-Belt, Partial Belt, Modular Belt:• Special Motorized Pulley designs are available for “non-belt, V-belt, partial belt, and modular belt” applications.See “Ambient Temperature Section” above.• It is essential that each special application be designed to adequately dissipate heat from the pulley surface.• Using a standard Motorized Pulley in one of these special applications could result in motor heat damage andvoids product warranty.• Contact Rulmeca for assistance with these applications.20) Oil and Oil Seal Maintenance:• All Motorized Pulleys are supplied with an appropriate quantity of oil. Oil type is specifiedby customer. Oil type and contents are given on the motor nameplate.• Standard, synthetic, food grade, low viscosity (for low temperature applications,) and highviscosity (in noise-sensitive areas) are all available. For approved oil types and quantities, see pages 90-91.• Motorized Pulleys require periodic oil changes and are supplied with two oil fill/drain plugs in end housing.Special “vertical mount” pulleys have four oil plugs (two in each end housing.)• The standard filling of mineral oil should be changed after each 10,000 operating hours undernormal operating conditions.• Synthetic oils should be changed after each 30,000 hours of normal operating condition.• Magnetic oil plug(s) should be cleaned during each oil change. A red dot plastic sticker indicates the positionof the magnetic oil plug.• Only approved non-conductive oil may be used in Motorized Pulleys.• Note that oil seals, regardless of oil type used, should be changed after 30,000 operating hours. On Motorizedwww.rulmecacorp.com 83TC101: 03/07

Technical Precautions for Design, Installation and MaintenancePulley types 320M to 800H oil seals may be changed without removing Motorized Pulley from conveyor. MotorizedPulley standard types 138E to TM320L require Pulley disassembly to change oil seals. Rulmeca servicepersonal or authorized local service providers to perform this work.• Take special precautions when changing brands of oil and types of oil because of potential oil incompatibility.Contact your local oil supplier for assistance.For example, when changing from standard to synthetic oil, it is necessary to:1. Completely drain old standard oil;2. Partially fill pulley with “Clean-Flush-Lubricate” (CFL) fluid;3. Run pulley for 20 minutes;4. Drain CFL fluid completely; then5. Fill pulley with appropriate amount of new synthetic oil.• Failing to observe these oil and oil seal precautions could shorten pulley service life and voids product warranty.• All the above instructions refer to Motorized Pulleys constantly working under full load. In case of MotorizedPulleys not working continuously under full load, the service life will increase considerably. When checking theoil, the cleanness of the oil is always the best guideline of– The wear and condition of the gears and bearings– Whether to change the oil immediately or possibly delay the oil change21) Pulley Diameter:• The type and size of conveyor belt will determine the minimum allowable Motorized Pulley diameter. Using apulley diameter too small for the belt can cause belt de-lamination, belt splice damage and can shorten bothbelt and pulley lagging life. Contact your belting supplier before specifying a pulley diameter.22) Regreasable Labyrinth Seals:• All Rulmeca Motorized Pulleys are hermetically sealed. Standard oil seals are designed to contain oil within theMotorized Pulley during normal operating conditions. They are capable of withstanding an internal pressure risethat occurs as the pulley motor temperature increases.• Optional regreasable labyrinth seals are available to protect oil seals from harsh operating or maintenanceconditions. Each labyrinth seal provides a barrier of steel and grease to prevent ingress of dust and fluid throughthe oil seal.• In abrasive operating conditions labyrinth seals should be periodically grease-purged to flush abrasive dustaway from the oil seal.• In wet conditions, where it is common to wash down equipment with high-pressure detergent spray, labyrinthseals should be refilled with grease after each wash-down. High-pressure sprays remove grease from thelabyrinth seal, removing an important part of the barrier to fluid ingress.• Grease should always be seen at the labyrinth gap.• If in some circumstances the re-grease frequency is high, an automatic greasing system is recommended.• Failing to perform necessary labyrinth seal maintenance could shorten service life and voids product warranty.23) Repair and Mechanical Maintenance:• Normally Motorized Pulleys require no specific attention during their operation other than the changing of oiland oil seals. They are ready for operation immediately after connection to the power supply.• If repair or maintenance is required, the Motorized Pulley must be disconnected from the power supply beforethe terminal box may be opened.• During a test run, the shaft ends must be correctly fixed to the support frame and suitable guarding must be providedaround rotating parts to protect personnel.24) Reversing Conveyors:• All Motorized Pulleys for a three-phase power supply are reversible. Mechanical backstop option is not possiblefor reversible conveyor applications.• The conveyor drive control system must be designed to bring the Motorized Pulley to a complete stop beforereversing conveyor belt direction.www.rulmecacorp.com 84TC101: 03/07

Technical Precautions for Design, Installation and Maintenance• Reversing conveyor direction without stopping the drive motor will damage motor and gearbox and voids productwarranty.25) Surface Coating:• Motorized Pulley models 400L to 800H are supplied with a standard salt water resistant primary paint coat of2.4 mil. For aggressive environmental conditions the Motorized Pulley should also be painted to a thicknessof 4.7 mil.• In this case it is essential that no paint enter the gap between the shaft and the end housing to prevent shaftsealing damage.• Motorized Pulley types 138E to 320H are supplied with powder coated end housings. The shells and shafts aretreated with anti-rust wax.26) Storage of Motorized Pulleys:• During storage Rulmeca Motorized Pulleys must be:– stored in a building or, as a minimum, covered by an awning.– protected against direct sunlight to insure that sealing system does not dry out.– rotated at least 180 degrees every 6 months to lubricate all internal components.• If Motorized Pulleys must be stored longer than 1 year, they must be tested before being put into operation.Such a test should include the following.– Motor winging should be checked with an insulation tester.– Winding resistance should be checked.– Thermal protector should be checked with a continuity tester.– Pulley should be connected to the power supply and run for a minimum of 30 minutes– Pulley should then be checked to verify that there are no oil leaks– Pulley should then be checked to verify that pulley body temperature does not exceed 160° F.• For safety reasons check that the Motorized Pulley is properly fixed to the test frame during the test.27) Start-up:• Prior to initial start-up of Motorized Pulley:– Verify that Motorized Pulley nameplate data matches customer specification.– Ensure electrical connections are correct.– Check that Motorized Pulley is free to rotate.– Check that slack side belt tension is adequate to prevent belt slippage.– Check that belt is not over-tensioned.– Ensure that oil is present in the Motorized Pulley.28) Terminal Box:• Rulmeca Motorized Pulleys are available with terminal boxes or power cords to facilitate electrical installation.Power cords are available up to a motor power of 5.5 HP.• Two types of terminal box are available:1. Standard large terminal box with threaded brass terminals.2. Optional compact terminal box with clamp terminals (WAGO) up to a motor power of 5.5 HP.• Switch off Motorized Pulley power supply and control circuit(s) before opening terminal box.• Each terminal box has one or more conduit nipples and a cover plate. The cover plate should be removed tofacilitate termination of power and control wires within the terminal box. After wire connections are made coverplate should be replaced.• Terminal boxes should never be disassembled or removed from the end of the shaft to reorient conduit nipplelocation.• Modifications to terminal boxes should only be made by an authorized Rulmeca service center or after obtainingpermission and instructions, in writing, from Rulmeca.• A wiring diagram is placed inside the terminal box on the back of the terminal box cover.• Dismantling and reassembling a terminal box could cause a short circuit in the factory set (and tested) internalwiring and voids product warranty.www.rulmecacorp.com 85TC101: 03/07

Technical Precautions for Design, Installation and Maintenance29) Transport and Handling:• For safety reasons during transport and assembly a lifting rope suitable to support the weight of the pulley mustbe used. The weight of the pulley is stamped on the data plate and /or given in the catalog.• The rope must be fixed on the shaft ends.• For Motorized Pulley types 500H – 800H, a steel rope or chains should be fixed to the eyebolts,which are located on the mounting brackets.30) Variable Frequency Drive:• It is essential that each Variable Frequency Drive (VFD) be set within the motor’s allowable operating spectrum.For Rulmeca Motorized Pulleys the allowable frequency spectrum is 12 Hz to 66 Hz. There will be nomore than 5% torque loss within this range. This means that a Rulmeca Motorized Pulley is essentially a “constanttorque” conveyor belt drive within the allowable frequency range.• If operators attempt to drive the motor outside of the allowable range, then torque loss becomes significant,motor current draw elevates, motor cooling can become problematic, and product warranty is void.• Do not allow resonant frequencies in the power line to cause voltage spikes in the motor. It is possible forthe VFD to set up resonant frequencies in the power line between the VFD and the motor if the power line istoo long. Potential resonant frequencies may be eliminated in two ways. Either limit the distance between theVFD and the motor (some VFD manufacturers recommend cable lengths of 30 feet or less) or simply installa filter on the VFD output (available from VFD manufacturer.)• To avoid any radio interference the cable from motor to the VFD may be screened and properly grounded.• The power and current range of the VFD must be selected according to the full load amperage given on theMotorized Pulley data plate.• Do not undersize the conveyor drive. Make certain the conveyor drive provides enough belt pull at each endof the desired belt speed range. Remember that horsepower is linearly proportional to frequency.• For example, a 10 HP Motorized Pulley, which is designed to provide 1,080 lbs of belt pull at a conveyorspeed of 300 feet per minute (fpm) on a three phase power supply of 460 volts and 60 Hz, will provide approximately1,080 lbs of belt pull at 60 Hz. By definition, 1 HP equals 33,000 foot-lbs per minute. Therefore, this10 HP unit provides 1,080 lbs x 300 fpm = 324,000 ft-lbs/minute of power. This equates to (324,000 ftlbs/minute)/(33,000ft-lbs/minute/HP) = 9.8 HP.• If the Motorized Pulley described above is run at 30 Hz to provide a belt speed of 150 fpm, the torque (or “beltpull”) stays constant and the belt speed decreases. Therefore, the 10 HP unit described above, while runningat 30 Hz, will provide the following power. 1,080 lbs x 150 fpm = 162,000 ft-lbs/minute. Note that powerat this frequency only equals (162,000 ft-lbs/minute)/(33,000 ft-lbs/minute/HP) = 4.9 HP.• If design conditions require 10 HP at 300 fpm an 10 HP at 150 fpm, the designer will undersize the drive if hespecifies a 10 HP Motorized Pulley to be driven by a VFD at 60 Hz and 30 Hz. This is because the MotorizedPulley will only provide 4.9 HP at 150 fpm (30 Hz), as shown above. Therefore, if the designer knowshe will need 10 HP at 300 fpm and 10 HP at 150 fpm, he should specify a 20 HP unit designed to provide a300 fpm belt speed at 60 Hz. In this way when he uses a VFD to slow down the drive, he will have 10 HPavailable at 150 fpm (30 Hz0 and more than 10 HP available at 300 fpm (60 Hz.)• Contact VFD supplier to properly match the VFD capabilities with the conveyor Operating requirements andMotorized Pulley electrical characteristics.www.rulmecacorp.com 86TC101: 03/07

Motorized PulleysVariable Frequency DrivesTaconite Plant - After Conversion (Minnesota—USA)Taconite processor converted limestone feeder conveyor drives from 1975vintage DC motors and chain/sprocket speed reducers to 460 volt 3 phase60 Hz AC-powered Motorized Pulleys in 1995. Photo was taken beforechute and hood were reinstalled. ABB variable frequency drive (VFD) driveseach 19.72” diameter 5.5 HP motorized pulley to a maximum belt speed of120 FPM. Torque loss is limited to less than 5% because operating frequenciesare between 12 and 66 Hz.Technical Precaution: When driving motorized pulley with VFD on 460 volt3 phase 60 Hz power supply, always restrict frequencies to allowable frequencyspectrum of 12 to 66 Hz to avoid torque loss and heat build-up.Taconite Plant - Before Conversion (Minnesota—USA)Prior to 1995 conversion to Motorized Pulleys, old maintenance-prone chain& sprocket units served as DC motor speed reducers. Frequent lubricationof pulley pillow blocks, maintenance of chains/sprockets, expanded metalsafety guards, and DC motors were all eliminated with the installation ofMotorized Pulleys at this location.Technical Precaution: When converting a system to use a VFD do notundersize the conveyor drive. Make certain conveyor drive provides enoughbelt pull at each end of the desired belt speed range. Remember that horsepoweris linearly proportional to frequency (e.g. a 10 HP Motorized Pulley,designed to provide 1,080 lbs of belt pull at 460 volts and 60 Hz, will provideapproximately 1,080 lbs of belt pull at 30 Hz, but this equates to 4.9 HP.)Taconite Plant Control Panel- “Before & After” (Minnesota—USA)Left photo shows control panel of taconite plant DC-powered variable speedconveyor control system before 1995 conversion to AC drives. Note SCR's,relay banks, and timer banks.Right side shows control panel after conversion to AC motorized pulleyscontrolled with variable frequency drives. Elimination of SCR's and relaybanks improved reliability, simplified troubleshooting, and reduced energyloss.Technical Precaution: The power and current range of the VFD must beselected according to the full load amperage given on the Motorized Pulleydata plate.Various Limestone Quarries (Georgia—USA)Photo shows two of ten 15.75” diameter Motorized Pulleys installed 1994-1998 to automatically “choke feed” tertiary gyratory crushers. Working incombination with a VFD and an ultrasonic sensor, each Motorized Pulleydrives a 36” wide belt at a maximum speed of 120 FPM to transfer 4” minusproduct from hopper to crusher throat at 425 TPH.Technical Precaution: When driving motorized pulley with VFD, filter VFDoutput if it is more than 30’ from motorized pulley to avoid resonanceinducedvoltage spikes.www.rulmecacorp.com 87TC101: 03/07
