GENERAL INFORMATIONGENERAL CHARACTERISTICSMGM brake motors are asynchronousthree-phase totally enclosed fan cooledmotors (TEFC). The motor brakes in caseof power supply failure. The braking actionis always obtained through a very quickand precise stop and it guarantees a safeand prompt intervention in case of anunintentional power supply failure.The braking action is obtained withoutshaft axial sliding and it provides equalbraking torque in both directions of rotation.MGM brake motors are particularlysuitable for hoisting and traverse machines,tooling machinery, automatic andtransfer machinery in textile, ceramicand packing fields and in all those situationwhere precision and quickness inbraking are required.MGM brake motors are designed andassembled as real brake motors. Theperfect engineering and assembling combinedwith a strong and safe brake, makethese motors very reliable.As standard, on the IM B3 mounting (footmounted), feet are integrated in the frame(they are not attached to the frame)making the motor very sturdy. This featureis very important on those brake motorapplications where the stress duringstart/stop is very high.The brake disc lining material is asbestosfree with high friction coefficient and verylong lasting.The motors are provided with IP 54 enclosurerating and insulation class F.On request they can be provided with IP55 or IP 56 enclosure ratings and withclass H insulation .All MGM motors are designed for inverterduty. On request it is possible to supplythe motor with the encoder fitted on thesecond shaft end or to have the secondshaft end ready to fit an encoder. Forfurther information please refer to theencoder series section.MGM brake motors series are: BA andBM.BA seriesThe BA series consists of three phase, asynchronous brake motors totally enclosed fan cooled (TEFC). The BA series range startsfrom 71 up to 280 frame size. As standard, the brake power supply is AC 3-phase. On request DC brake can be provided with arectifier integrated in the terminal box. The rectifier is provided with an over-voltage and radio frequency emission protectiondevice. All BA series motors are provided with manual brake release. The BA series cooling fan is fitted between the motor andthe braking assembly. The brake moving element and the brake coil have a laminated magnetic nucleus to reduce losses and toallow very fast braking. BA series main features are a very quick braking action, both in unlocked and high torque braking, aconstant braking time and a very high number of start/stop cycles also under severe applications.BM seriesThe BM series consists of three phase, asynchronous brake motors totally enclosed fan cooled (TEFC). The BM series range startsfrom 56 up to 160 frame size. As standard the brake power supply is DC with a rectifier integrated in the terminal box. The rectifieris provided with an over-voltage and radio frequency emission protection device. The cooling fan is fitted at non-drive shaft end.BM series main features are low braking noise, gradual acceleration during the motor start and stop and the reduced overalldimensions.The BA and BM series are also available in the following main versions:PV (BAPV, BMPV): with flywheel that allow progressive start and stop, particularly suitable for traverse application.F (BAF): with double brake disc and extremely high brake torque.AV-SV with forced cooling (BMAV with axial forced cooling, BASV with double radial forced cooling)4

Enclosure Rating (Protection Degree)The enclosure rating of the motor has to be suitable to the environment conditions the motor operates in. According to theIEC34-5 (EN 60034-5) standard the designation of the protection degree is expressed by means of a symbol made up of twoletters (IP) followed by a two digit number. The first digit indicates the protection degree provided by the motor enclosure incontact with parts in motion, electrically energized, or against the penetration of foreign bodies. The second digit indicatesthe protection degree of the motor enclosure against damages caused by the penetration of liquids.First digit0 No protection.1 The machine is protected against the penetration of solidbodies greater than 50 mm in diameter (for example, protectionagainst the accidental touch of a hand).2 The machine is protected against the penetration ofsolidbodies greater than 12 mm in diameter.3 The machine is protected against the penetration of solidbodies greater than 2.5 mm in diameter.4 The machine is protected against the penetration of solidbodies greater than 1mm in diameter.5 The machine is protected against the penetration of dust.The penetration is not completely avoided, but should notcompromise the good functioning of the machine.6 Dust tight machineIP................... First digit .......................Second digitSecond digit0 No protection.1 Vertical dropping of water on the machine will not result indamaging effects.2 Vertical dropping of water on the machine will not result indamaging effects when the machine is not inclined more than15° from its normal position.3 Water or rain dropping on the machine at an angle up to60° will not result in damaging effects.4 Water spraying on the machine from any angle will notresult in damaging effects to the machine.5 Water jets on the machine from any angle will not result indamaging effects to the machine.6 Waves of water will not result in damaging effects to themachine.7 Immersing the machine in water under specific conditionsof pressure and time will not cause the ingress of a damagingquantity of water.8 Immersing the machine permanently in water underconditions of pressure and time given by the manufacturer willnot result in damaging effects.GENERAL CHARACTERISTICSMGM brake motors come with standard IP54 enclosure rating. On request, motors can be provided with IP55 or IP56 enclosurerating. For use in standard industrial environments IP54 is sufficient.

The available rated voltages are shownin the table below under “Nameplate voltage” at 50 Hz and 60 Hz, while the corresponding voltages on which the motor isable to run are shown under “Usable voltage”.230 / 400 50190 / 330 50208 / 360 50400 / 690 50Nameplate voltage277 / 480 60220 / 380 60254 / 440 60480 / 830 60Usable voltage240 / 415 50 220 / 380 50 265 / 460 60208 / 360 60 230 / 400 60200 / 346 50 240 / 415 60380 / 660 50 415 / 717 50It’s important to understand the torque vs. RPM curvesfor different voltages supplied to the motor (on the side)particularly for those motors running under heavy duty. Ifyou are supplying the brake with a lower voltage than thenominal one, the air gap has to be adjusted more frequentlythan in the case of nominal voltage supply in order toguarantee a constant high brake performance.1201101009080706050403020100Torque %440 V400 V360 V0 10 20 30 40 50 60 70 80 90RPM %100Operating at 60HzMGM motors with rated voltage of 230/400V 50Hz maintain the same rated and starting torque if operating at 277/480V 60 Hz while theRPM increase by about 20% (see torque vs. RPM comparing curves 1 and 2 here below).The AC brake coil on BA series works equally well if operating either at 230/400V 50Hz or at 277/480V 60Hz. The DC brake coil withnameplate voltage of 110V, 230V or 400V on BM and BA series has to be supplied at 110V, 230V or 400V single phase respectively bothat 50 Hz or 60 Hz (i.e. a 230V brake can be supplied single-phase at 230V 50Hz or at 230V 60 Hz).MGM is able to provide motors and brake coil suitable for operating on 220/380V 60Hz power supply. It is not advisable to run motorsdesigned for 230/400V 50Hz and 277/480V 60Hz on 220/380V 60Hz voltage supply as the power remains the same, but the startingtorque is reduced by 35% (see curves 1 and 3 here below).MGM strongly recommends not to use a 277/480V 60Hz (230/400V 50Hz) AC brake coil on 220/380V 60Hz power system as it resultsin a significant loss of performance.DC brakes with a rated voltage of 230V 50Hz can be used on 220V 60Hz and those with a rated voltage of 400V 50Hz on 380V 60Hzpower system.The diagram below shows different curves (torque vs. RPM) for a 230/400V 50Hz (277/480 60Hz) rated voltage motor running on differentpower systems.12230/400V 50Hz (277/480V 60Hz) rated voltagemotor running on 230/400V 50 Hz power system.230/400V 50Hz (277/480V 60Hz) rated voltagemotor running on 277/480V 60 Hz power system.Torque %100%65%1 233230/400V 50Hz (277/480V 60Hz) rated voltagemotor running on 220/380V 60Hz power system.100% 120% RPM %It’s important to point out that, if running the motor at 60Hz instead of 50 Hz, the maximum number of starts reduces by about 15-20%, andthe noise level increases by about 3dB due to the increased speed of the cooling fan.14
Service Duty TypesThe most common duty types are described in this paragraph and a method to calculate the permissible power rise-up isgiven. Please contact MGM for different types of duty.The motor operates with constant loadfor a period of time sufficient to achievethe thermal equilibrium.PowertsTemperature<strong>Co</strong>ntinuous duty S1Limited length duty S2GENERAL CHARACTERISTICSThe motor operates with constant loadfor a limited period of time not sufficientto achieve a thermal equilibrium.

MGM motor running on Inverter Duty (Frequency <strong>Co</strong>nverter).GENERAL CHARACTERISTICSAll MGM motors are designed to be suitable for inverter duty. See below to understand the motor operating under invertercontrol:The motor speed depends on the power supply frequency. Basically the inverter works converting the power input from the linewith a fixed amplitude and frequency into a voltage supply with a variable amplitude and frequency suitable to control the motorspeed. Inverter can’t generate an output voltage higher than the input voltage while it can increase the frequency above theinput rated value; <strong>Co</strong>nstant torque regulation range means a range where the inverter is able to keep the nominal ratio of voltageto frequency constant; in our diagram this range is up to 50 Hz.<strong>Co</strong>nstant power (or flow) regulation range means a range where the inverter can increase frequency (and so the motor rotationspeed), without voltage increase to the motor (and consequentlythe torque); in our diagram this range exceeds 50 Hz;Operating diagram shows the percent values of the torqueavailable both in continuous and overloading running; Whenthe motor is running within constant torque regulation range(frequency below 50 Hz), it is necessary to check that continuousslow running does not cause overheating; in that case servofan (see operating diagram) is needed. When the motor isrunning within constant power regulation range (frequencyabove 50 Hz), it is necessary to check if the torque requiredby the load does not exceed the torque indicated on theoperating diagram, otherwise malfunction and eventual interventionof inverter overload protection devices could occur.T/TnVector control – <strong>Co</strong>ntinuous DutyV/f control – <strong>Co</strong>ntinuous DutyVector <strong>Co</strong>ntrol – Forced <strong>Co</strong>oling or IntermittentDutyV/f control – Forced <strong>Co</strong>oling or IntermittentDutyVector <strong>Co</strong>ntrol – Overloading conditions withIntermittent DutyV/f control – Overloading conditions with IntermittentDutyHzRPMThe brake should be supplied separately from the motor on brake motors controlled by inverters, to ensure the proper workingof the brake coil. In this case the double terminal board box option must be requested. On brake motors with AC brake coil, it isalso advisable to use a safety overload cutout (MGM type RC04) on the power supply of the brake coil.The starting torque of a motor running on inverter is different from the one of a motor connected directly on line. Be sure to selectan inverter with technical specifications suitable for the work load of the machine it is intended to be used on.An inverter changes the electrical wave pattern to the motor from purelysinusoid to switching typical shape. Because of undesirable harmoniccomponents added to the underlying power supply, a motor controlledby an inverter has higher losses, and an increased vibration and noiselevel. The efficiency reduction varies according to the type of inverterused. In the figure on the right the harmonic content on the powersupply of a motor under inverter can be seen (blue indicates theunderlying power supply, grey indicates the harmonics).% A100908070605040302010HzPlease contact MGM technical staff when using inverters with power supply higher than 400V or when using long cables betweenthe motor and the inverter as both situations can be critical for the motor winding insulation system.16
MGM motor running on Inverter Duty (Frequency <strong>Co</strong>nverter)The interference generated by electronic power devices such as inverters, can influence equipment sensitive to interference, suchas computers, load cells, photocells, temperature regulators, magnetic intrusion switches, or capacitance grounding circuits, andcontrol wiring.Whenever it is necessary to reduce the interference caused by the inverter the following practical suggestions should be implemented.Disturbances are highest nearby the inverter, and can be attenuated by increasing the distance. Sensitive devices should be keptat least 50 cm from the frequency converter. The power wiring should be kept at least 50 cm away from the control wiring. Usepower cables as short as possible. Power cables longer than 10 m is a strong source of disturbances, and can cause malfunctions.An EMI filter may be necessary on the power supply line.Information on the correct wiring of the inverter to the motor to reduce the interference should be obtained from the invertermanufacturer.GENERAL CHARACTERISTICSBalancingMGM brake motors are balanced with a half key applied to the motor shaft ends, according to the EN 60034-14. Reducingvibrations is important both to avoid motor damage, especially to the bearings, and to avoid damage to the machinery to whichthe motor is coupled. It is advisable to balance the parts of the attached machinery (the coupling, the pulleys, etc.) in order toavoid vibrations. The maximum permissible vibration intensities for different frame size, according to the norm EN 60034-14,can be seen in the table below. As standard motors are supplied with normal class balancing, upon request they can be suppliedwith reduced or special class balancing.ClassRated speed (RPM)Effective maximum values of vibration speed (mm/s) depending on frame size H56 mm ≤ H ≤ 132 mm 132 mm < H ≤ 225 mm 225 mm < H ≤ 400 mmN (Normal)600 ≤ n ≤ 36001.802.803.50R (reduced)600 ≤ n ≤ 18001800 < n ≤ 36000.711.121.121.801.802.80S (Special)600 ≤ n ≤ 18001800 < n ≤ 36000.450.710.711.121.121.80The noise of a running electric motor is mainly generated by the magnetic field, the bearings and the cooling system. The most relevantnoise level is generated by the cooling fan. Technical data sheets report the values of the sound pressure in dB (A) according to ISO1680. The above mentioned values should be increased by about 3-4 dB on motors operating at 60 Hz. On request it is possible toprovide motors with low noise level. During the braking action the noise level depends on the air gap (distance between the brake coiland the brake moving element). Periodic air gap adjustment provides lower noise levels.Noise17
Protection DevicesThe motor should be provided with protection devices to protect against non ordinary working conditions. The use of protectiondevice on the line is particularly advisable (i.e. varistors) for those motors running at low speed (8, 12, 16 poles) to preventearly wear of windings and of contacts caused by voltage peaks during the switching on.Operation conditionsExcess currents 200% InHeavy starts, reversing operationStallingStarting on two phasesVoltage deviationsFrequency deviationsInsufficient motor coolingProtection typeFuses Protective circuit breakers Thermal protective device on the windingsno protectionno protectionpartial protectionno protectionno protectionno protectionno protectionexcellent protectionpartial protectionpartial protectionpartial protectionexcellent protectionexcellent protectionno protectionexcellent protectionexcellent protectionpartial protectionexcellent protectionexcellent protectionexcellent protectionexcellent protectionGENERAL CHARACTERISTICSOn request MGM is able to supply motors equipped with thermistors PTC or bimetallic PTO thermal protectors:Bimetallic Thermal Protectors (PTO): three bimetallic sensors in series with normally closed contacts, fitted on the windingsheads. They control a switch (not provided with the motor) that interrupts the power supply when getting close to dangeroustemperature. The nominal voltage and current are 250 V and 2,5 A A.C. respectively while the temperature of intervention is 140°C. The contact closes again with a temperature reduction of at least 35 °C. The bimetallic thermal protectors leads are connectedto a terminal board located in the main terminal box. The presence of PTO is shown by the writing “TP” in the field 29 of thenameplate (see pertinent paragraph on page 8).Thermistors (PTC): three thermistors in series (conforming to DIN standards 44081 and 44802), fitted on the windings heads.The resistance of the thermistors changes with temperature and when getting close to the nominal intervention temperature thesharp increase of resistance guarantees a precise intervention of the safety devices. The thermistor only senses the temperatureso a cut-out device (not provided with the motor) must be added to interrupt the power supply to the motor. The maximum PT<strong>Co</strong>perating voltage is 30 V DC while the intervention temperature is 130 °C on class F motors and 140 °C on class H motors. ThePTC leads are connected to a terminal board located in the main terminal box. The presence of PTC is shown by the writing “TM”in the field 29 of the nameplate (see pertinent paragraph on page 8).Over-voltage protectionLow speed motors: when starting motors with a high number of poles (i.e. 8, 12, 16), voltage peaks can be generated damagingthe motor insulation materials and contacts. In these cases it is advisable to install safety over-voltage protection devices.On request MGM provides over-voltage protection devices such as RC04 for motors up to 4 kW and RC10 for motors up to 10kW. Please note that these devices should not be installed if the motor is controlled by an inverter.<strong>Brake</strong> coil: DC brake coil is supplied as standard with a rectifier fitted with a protection device against over-voltage and with afilter against the radio frequency emissions. The AC brake coil doesn’t generally need this type of protection devices. In case ofa very high start/stop frequency or in case of critical line voltage situation it is recommended the use of RC04 filter in order tolimit the electrical interference on the brake.19
BA SeriesB5B14B320
GENERAL CHARACTERISTICSBA SeriesBA series consists of three phase, asynchronous brake motors totally enclosed fan cooled (TEFC). BA series range starts from 71up to 280 frame size. The motor brakes in case of power supply failure. The braking action is always secured through a very quickand precise stop assuring a safe and prompt stop in case of unintentional power supply failure. The brake torque remains the samein both directions of rotation and the motor brakes without shaft axial sliding. As standard the brake is AC 3-phase voltage supplywith brake leads connected with motor leads in a single terminal board while on request it is possible to supply the brake separatelywith a second terminal board or to have a DC brake supply with a built-in rectifier fitted inside the terminal box. The rectifier isprovided with over-voltage and radio frequencies emission protection devices. BA series motors tolerate high overloading rate andare capable of withstanding overheating so as to guarantee the best reliability even under tough operating conditions. All MGMseries motors have been designed to be controlled by inverters. The motor winding insulation is class F, while class H is availableon request. Motor construction type is totally enclosed externally cooled and IP54 enclosure (IP55 and IP56 available on request).<strong>Motors</strong> up to 132 frame size are fitted as standard with a hexagonal hole on the shaft at the non drive end to allow manual rotation,even if power is off. All BA series motors are provided as standard with hand brake release screw.BA series brake disc has a large lining surface that allows high brake torque, low disc wear and consequently low maintenancecost. The brake torque can be easily adjustable to the desired value just by screwing some nuts. Thanks to its special constructionthe brake friction surface is self-ventilated on the motor side, permitting a high brake workload and keeping brake time constant.The brake lining material is asbestos free.BA series motor frame is made of die cast, light metal on motors up to 132 size and the terminal board box, provided with cableglands and plugs, is positioned 180° above the motor support feet. The frame is made of cast iron starting from 160 frame sizeand the terminal box is located on the right side (drive-end view). Shields and flanges are made of aluminium on motors up to 90frame size, and of cast iron on motors of 100 frame size and above. As standard feet are frame integrated (they are not simplyattached to the frame) on IM B3 mounting (foot mounted) making the motor very sturdy. This feature is very important for thoseapplications where the motor is much stressed during the starts and stops.The brake friction surfaces are made of cast iron as a standard. The brake moving element and the brake coil have a laminatednucleus to reduce electrical losses and to secure a very quick brake intervention.BA series main features are its sturdy construction, quick braking action, constant braking time, high number of permissiblestart/stop cycles also under severe applications, easily adjustable brake torque, low maintenance costs.21
BA series brake groupBA seriesAir gap adjustmentThe air gap (24), 60 that is the distance between the two magnetic cores, the brake coil (24) 25 andbrake moving element (24), must stay within the value expressed in the chart below. It is notadvisable to exceed the expressed value, in order to avoid vibrations of the brake movingelement, very loud noise, the brake coil burning or even the whole brake assembly failure. Itis advisable to check periodically the air gap because it increases as a consequence of thebrake disc wear. In order to set the air gap to the indicated value, you have to loosen the nuts(24) 21 (24) 22 so to move the brake coil (24) 25 towards the brake moving element (24). Once thisoperation has been settled be sure to tighten the locknuts. The above mentioned procedureisn’t valid for BA 250-280 serie-motors, for which we pls you to contact us.Frame SizeMin Air Gap [mm]Max Air Gap [mm]71-800.250.5<strong>Brake</strong> torque adjustment90-1000.30.6112-1320.40.8160÷2000.51.0The brake torque is proportional to the springs (18) compression, which can be adjusted tightening orloosening the locknuts (20). The compression of the three springs must be as even as possible. Oncethe brake is properly supplied, if the brake coil isn’t able to attract the brake moving element with a quickstroke and to keep it attracted without any vibrations, check the air gap adjustment and, if this inconveniencestill persists, loosen the locknut (20) by two threads and try again until the proper functioning is obtained.It is important to consider that some motors can be equipped with 3 springs and some others with 6.(see page 23). Once this operation is completed, check the brake torque to make sure it is set to thedesired value. Never set the brake torque to a higher value than the one indicated on the motor nameplate.2250.61.2191723241860202122262725Permissible start frequency under loadThe technical data tables provide the ideal no-load start frequency (Z0). The permissiblestart frequency when an external load is applied (Z load) can be found with the followingformula:Zload=Z0 • K • Rwhere “Z0” is the table-value for the selected motor and “K” and “R” are factors determinedby the curves on the side; the factor “K” is related to the ratio of the moment of inertia ofthe applied load (Japp) to that of the motor (Jmot) while the factor “R” is related to the ratioof the resisting torque (Tr) to the starting torque (Ts). This calculation gives an approximativeindication only and it has to be operatively tested for confirmation. If the required startingfrequency is close to Zload, it is advisable to use a motor equipped with thermal protectors.It is necessary to check the maximum energy dissipation limit of the brake group and themaximum motor RPM in those applications where high moment of inertia is involved. Onrequest is available a special brake disc material capable to withstand very high dissipationenergy.

<strong>Brake</strong> torque and brake spring compressionBA series motors are provided as standard with a brake torque set to 60 - 70% of the maximum admissible braketorque indicated on the nameplate. On request the motor can come already set to a specific brake torque value differentfrom the standard one. The brake torque is shown in the diagrams here below as a function of the brake assemblyspring compression; for BA250-280 motors pls contact MGM. The shown values refer to BA series motors mounted inhorizontal position with an AC brake coil. DC brakes have the same trend as AC brakes even if they have lower braketorque, as shown in the table below. For BAK 100-132 motors series the brake torque changes in a different way thanshown in the diagrams. Please contact MGM for further information. The values shown in the diagrams are onlyindicative as application conditions, brake lining wear and temperature, can affect the real brake torque. Whenever it isnecessary to adjust the braking torque to a specific value it is advisable to directly measure the obtained brake torqueafter each brake torque adjustment. <strong>Co</strong>nsider that the motor mounting position influences remarkably the effectivebraking torque when low brake torque values are involved.

Motor characteristic values reported in the tables referto continuous duty (S1), 50 Hz frequency, ambient temperaturemax. 40 °C, altitude up to 1000 m. above sea level operatingcondition.2. DC brake is provided on request only on BA series motors. <strong>Brake</strong> current consumption values refer to a rated voltageof 3-phase 400V for AC brakes and single-phase 230V forDC brakes.3. The table shows the sound pressure noise level, measuredat one metre range from the motor according to the Acurve(ISO 1680). The shown noise levels refer to motor no-loadoperating condition and should be regarded with a toleranceof ± 3dB.4. Max brake torque and Z 0 values refer to AC brake. Go topag. 23 for DC max brake torque values.5. The expressed Z 0 values refers to AC <strong>Brake</strong>. Z 0 is themax number of no-load starts. It is meant for calculationpurposes only, and is used to obtain the max number ofstarts with load according to the formula expressed at page22. The number of starts with load (Zload) is indicative andit has to be operatively tested for confirmation.

<strong>Brake</strong> Linings Wear, Starting and Braking timebrake linings wear<strong>Brake</strong> linings wear is mainly affected by the environmental conditions in which the motor operates, by the frequency of starts, bythe energy dissipated at each stop and by the torque provided by the brake. The lining temperature rises with the braking frequencyand with the moment of inertia applied to the shaft. When the lining temperature raises, the lining wear increases and consequentlythe braking time is longer. BA series motors are designed to have continuous cooling of the braking surfaces so as to reducebrake disc wear to have a shorter braking time.The life cycle of the brake linings can be roughly expressed by the number of brake interventions and can be approximatelycalculated as follows:n = Wtot / Wbwhere Wb (J) is the work done during each braking action and Wtot (J) is obtained from the table for each type of brake motor.However, it is necessary to check the brake disc wear periodically to replace the brake disc before it is completely worn. If youwant to estimate the interval between two successive air gap adjustment in a specific application, note that the brake linings wearis greater than usual during the run-in (a few thousands stops).On PV series brake motors Wtot shown in the table have to be multiplied by 0.5 and the moment of inertia have to be calculatedconsidering the presence of the flywheel. The indicative number of AC brake stops NintAC between two successive air gapadjustments on a BA motor is given by the following formula:NintAC = ErBA / Wbwhile the NintDC for DC brake motors is given by : NintDC = NintAC • 0.65BA series71 80 90 100 112 132 160 180 200225Wtot (MJ)Er (MJ)5375670580952951148105143813022552003290290435538543553855226462For BA 250-280 pls contact MGM. The indicative number of DC brake stops NintBM between two successive air gap adjustments on a BMmotor is given by the following formula:NintBM = ErBM / WbErBM values are shown at pag. 39 (BM section).Starting and braking timeStarting current for an asynchronous motor is always much higher than the nominal current. When the starting time is excessivelylong, there are electromechanical disturbances and higher temperatures on winding, damaging the motor. For information onmaximum starting time allowed for each type of motor, please contact MGM. An indicative value for starting time ts (expressedin seconds) and the angle of rotation ϕs (expressed in radians) can be obtained as follows:(Jmot + Japp)•nta•nts =ϕ s =9.55 (T - Tload)19.1Where Japp (Kgm 2 ) is the moment of inertia referred to the motor shaft, Mload (Nm) is the opposing torque to the motor, Jmot (Kgm 2 )is the moment of inertia of the motor, n (RPM is the rated motor RPM), T is the average starting torque, T=(0,8÷0,9)Ts (see thetechnical data table for Jmot, n and Ts of the selected motor).An indicative braking time tf (s) can be calculated as follows:<strong>Brake</strong> electrical reaction time tB (ms)Motor TypeBA 71-80-90BA 100-112BA 132-160BA 180-200BA 225BA 250BA 280AC <strong>Brake</strong>791212141414DC <strong>Brake</strong>(Standard)80808590100--DC <strong>Brake</strong>(Quick)2030303035--tf =Jtot • n9.55 (Tb ±Tload)The reported tB times are valid only if the motor is connected with the brake.

General CharacteristicsBM seriesBM series consists of three phase, asynchronous brake motors totally enclosed fan cooled (TEFC). BM series range starts from 56 up to160 frame size. The motor brakes in case of power supply failure. The brake torque remains the same in both directions of rotation andthe motor brakes without shaft axial sliding. As standard the brake is DC voltage supply with a built-in rectifier fitted inside the terminalbox. The rectifier is provided with over-voltage and radio frequencies emission protection devices. Two different types of rectifier wiringcan be chosen according to two different brake intervention time.BM series is designed in order to have a braking action as quiet as possible. BM series motors tolerate a high overloading rate and arecapable to withstand overheating so to guarantee best reliability also under tough operating conditions.All MGM motors have been designed to be controlled by inverters. The motor winding insulation is class F, while class H is available onrequest. Motor construction type is totally enclosed externally cooled and IP54 enclosure (IP55 and IP56 available on request).<strong>Motors</strong> up to 132 frame size are fitted as standard with a hexagonal hole on the shaft at non drive end to allow manual rotation, even ifpower is off. On request, BM series motors can be provided with side manual brake release lever. The brake disc lining material is asbestosfree and the lining mixture is formulated to have a high friction coefficient and long lasting.BM series motor frame is made of die cast, light metal on motors up to 132 size and the terminal board box, provided with cable glandsand plugs, is positioned 180° above the motor support feet. The frame is made of cast iron starting from 160 frame size and the terminalbox is located on the right side (drive-end view). Shields and flanges are made of aluminium on motors up to 90 frame size, and of castiron on motors of 100 frame size and above. On IM B3 mounting (foot mounted) feet are frame integrated (they are not simply attachedto the frame) as standard and it makes the motor very sturdy. This feature is very important for those applications where the motor ismuch stressed during the starts and stops.BM series main features are the low braking noise, gradual acceleration during the motor start and stop and reduced overall dimensions.37
BM series brake groupBM seriesGeneral descriptionBM series motors are equipped with DC brake coil. DC brake coil is supplied through a rectifier located in the terminal box (standardvoltage supply is 230V 50/60 Hz). The rectifier is provided with over-voltage and radio frequencies emission protection devices.The brake torque remains the same in both directions of rotation and the motor brakes without shaft axial sliding. <strong>Brake</strong> torquecan be set loosening or tightening the adjustable springs (78) where available or removing the central springs or replacing thefixed ones.Never set the brake torque to a higher value than the one indicated on the motor nameplate.BM series motors are fitted as standard with a hexagonal hole on the shaft at non drive end to allow manual rotation. On requestBM series motors can be provided with brake release return lever located on the motor side.Air gap adjustmentThe air gap (60), that is the distance between the two magnetic cores,the brake coil (60) 75 and brake moving element (60), 74 must stay withinthe value expressed in the chart below. It is advisable to check periodicallythe air gap because it increases as a consequence of the brake discwear. In order to restore the air gap within the proper value release theconnecting screws (60), 77 move the brake coil (60) 75 towards the brakemoving element (60) 74 operating on the fixing screws (60). 79 Once thisoperation has been settled be sure to tighten clockwise the connectingscrews (60) 77 so to fasten again the brake coil.60 76787178Frame SizeMin Air Gap [mm]Max Air Gap [mm]63/710.20.6800.20.7900.30.81000.30.91120.31.01320.41.11600.41.17584 77 73 74 79Permissible start frequency with loadThe technical data tables provide the ideal no-load start frequency (Z0). The permissible start frequency when an external load isapplied (Z load) can be calculated as follows:Zload=Z0•K • RR1K1,20,810,60,40,80,60,40,20,200 0,2 0,4 0,6 0,8 1,0T r / T swhere “Z0” is the table-value for the selected motor and “K” and “R” are factors determined by the curves on the side; the factor “K”refers to the calculated ratio between the moment of inertia of the applied load (Japp) and that of the motor (Jmot) while the factor “R” isthe calculated ratio between the resisting torque (Tr) and the starting torque (Ts). This calculation gives an approximative indication andit has to be operatively tested for confirmation. If the required starting frequency is close to Zload, it is advisable to use a motor equippedwith thermal protectors. It is necessary to check the maximum energy dissipation limit of the brake group and the maximum motorRPM on those application where high moment of inertia is involved.

Motor characteristic values reported in the tables refer to continuousduty (S1), 50 Hz frequency, ambient temperature max. 40 °C, altitudeup to 1000 m. above sea level operating condition.2. The expressed brake torque is the max admissible one. <strong>Brake</strong>current consumption values refer to a rated voltage of 230V ACsingle-phase.3. The table shows the sound pressure noise level, measured at onemetre range from the motor according to the Acurve (ISO 1680). Theshown noise levels refer to motor no-load operating condition andshould be regarded with a tolerance of ± 3dB.4. Z 0 is the max number of no-load starts. It is meant for calculationpurposes only, and is used to obtain the max number of starts withload according to the formula expressed at page 38. The number ofstarts with load (Zload) is indicative and it has to be operatively testedfor confirmation. The use of Thermo-protectors is strongly recommendedwhen the operative number of starts is close to the calculatedZload.

The table shows the sound pressure noise level, measured at onemetre range from the motor according to the Acurve (ISO 1680). Theshown noise levels refer to motor no-load operating condition andshould be regarded with a tolerance of ± 3dB.4. Z 0 is the max number of no-load starts. It is meant for calculationpurposes only, and is used to obtain the max number of starts withload according to the formula expressed at page 38. The number ofstarts with load (Zload) is indicative and it has to be operatively testedfor confirmation. The use of Thermo-protectors is strongly recommendedwhen the operative number of starts is close to the calculatedZload. It is necessary to verify the max permissible brake energydissipation and the max permissible RPM.43

Traverse motors with progressive start and stopPV seriesA few problems such as swinging of suspended loads, slipping of trolley wheel on rails, the breakage of some delicatemechanisms can occur on traverse applications. All these problems can be solved using progressive start/stop systems suchas clutches, hydraulic couplings, slip-ring motors or soft start devices. Experience has shown that progressive start/stop brakemotor is a valid alternative to all the other adducted systems. Traverse motors are provided with a flywheel whose dimensionand weight are calculated in order to have an adequate moment of inertia. The ratio of rated torque to starting (locked rotor)torque is calculated in order to achieve the best progressive performance.The flywheel accumulates energy during the start and gives it back during the stop resulting in a progressive change of therotating speed. PV series motors don’t need adjustments with load change or any special maintenance and the progressiveaction is directly proportional to the load increase. During the planning stage it is necessary to carefully choose the propermotor power as an insufficient power could cause overheating while a too powerful motor could reduce the effect of theflywheel progression.PV series motors are designed with a special rotor to reduce the starting (locked rotor) current so to allow heavy start/stopduty cycle, even if the starting period doesn’t have to be too long in order to avoid overheating.BAPV series motors provide a reduced brake torque, resulting in a really progressive braking action. The brake torque of BAPVmotors is about the half of the corresponding BA standard brake motors while BM and BMPV series motors have the samebrake torque.BAPV motors are fitted with a flywheel strongly secured to the motor shaft while BMPV motors are fitted with cast-iron coolingfan replacing the thermoplastic one.PV series motors are available with the following features or option:- Separate brake supply,- Manual brake release,- Suitable for mounting in any position (vertical, horizontal, etc.)- Two speedsThe table below shows the moment of inertia increase (Kgm2) for BAPV and BMPV series.Motor Type 6371 80 90 100 112 132160BAPVBMPV-2.97 • 10 -3 6.78 • 10 -3 1.11 • 10 -2 1.82 • 10 -2 2.89 • 10 -2 5.8 • 10 -23.1 • 10 -4 1.93 • 10 -3 3.12 • 10 -3 9.97 • 10 -3 1.52 • 10 -2 1.52 • 10 -2 -14.3 • 10 -2-The total moment of inertia of a chosen motor is the moment of inertia of a standard brake motor (see motors technical data)plus the flywheel moment of inertia (shown in table above).Example:moment of inertia of BAPV 71 B4 = moment of inertia of BA 71 B4 + flywheel type BAPV 71 B4 moment ofinertia = 8.1•10 -4 + 2.97•10 -3 = 3.78•10 -3 Kgm 2 .The table below shows the maximum brake torque (Nm) for BMPV with DC brake and BAPV motors with AC brake or DC brake:Motor Type 6371 80 90 100 112 132160BMPVBAPV - A.C.BAPV - D.C.5--574.51097.5201915402521604030-7560-957746

Hoisting <strong>Motors</strong>BAPK seriesBAPK series motors are available starting from 100 up to 225 frame size. Powers and poles are the same as the BA series motors(see BA technical data).BAPK series motors have the same motor construction as BA series motors but present some special parts. Single and most-offthe two speed BAPK motors are fitted with a special rotor (P rotor) that increases the starting torque (locked rotor) by 20% aboutand that reduces the starting current (locked rotor) by 10% about.The brake disc nucleus and hub are made of steel (see k brake disc section). AC brake coil is provided to secure a fast brakeintervention. Feet are frame integrated on B3 mounting (foot mounted) and not simply attached to the frame. This feature guaranteebest reliability of brake motors for hoist application. Shields and flanges are made of cast iron. Frame is made of aluminium from100 up to 132 frame size (132 cast iron frame is available on request) while it is made of cast iron starting from 160 frame size.Dimensions are the same as the BA series (dimensions sheet pag. 34). To purchase BAPK series motors the writing BAPK has tobe clearly stated in the order (i.e. BAPK 112 MB4/16).K <strong>Brake</strong> DiscNucleus and hub of K brake disc are made of steel that means a higher sturdiness and moment of inertia. The K brake disc is provided asstandard on motors starting from 160 frame size while it’s available on request on motors from 100 up to 132 frame size.BA standard brake motors up to 132 frame size are made of a special aluminium/thermoplastic material.K brake disc is strongly recommended for hoisting application, safety application or under high environment temperature (50°C or above).For further information please contact MGM.K brake disc has a shorter lasting than standard brake disc as a consequence of the increased moment of inertia therefore it’s advisable touse standard brake disc on heavy start/stop duty cycle application where the k disc is not necessary. To purchase motors with K brake disc,the writing BAK has to be clearly stated in the order (i.e. BAK 112 MB4).Premium <strong>Brake</strong> Torque <strong>Motors</strong> – BAF seriesBAF seriesBAF series motors are brake discs motors providing a very high brake torque. BAF series motors are particularly suitable for thoseapplications where it’s needed to keep the motor locked up also under a very high turning moment. BAF series motors are providedwith AC brake. BAF motors are available starting from 100 up to 225 frame size. The table below shows the BAF series brake torquevalues.Motor Type BAF 100BAF 112BAF 132BAF 160BAF 180BAF 200BAF 225<strong>Brake</strong> Torque Max (Nm) 7512022528545045060048
Forced <strong>Co</strong>oling <strong>Motors</strong>AC electric motors operating in non standard conditions (low frequency inverter duty, long overcharge periods, heavy dutycycles) could need additional cooling servo-fan. BASV series motors with forced cooling are provided with two additionalcooling servo-fans fixed on the motor frame. This cooling system is an MGM patent.SV series motors have the following features:1. The standard self cooling fan inside the motor is kept additionally to the two cooling servo-fans.2. The whole heating surface is increased as the fan fixing system is itself a heat dissipation element additionally to the existingfins on the frame.3. Low noise level.4. No additional motor length compared to the standard one.5. Manual brake release with manual rotation.6. Uniform winding cooling along the whole motor length.7. The brake friction surface is cooled on the motor side.SV seriesWhere the forced cooling is used to limit the operating temperature in heavy start/stop duty application, it should be noted that theefficiency of the forced cooling increases with the number of pole of the motor. It’s hard to estimate the amount of hot air removed by theforced cooling fans but it can be roughly said that it is the same as the air removed by the standard servo-fan of a 4 pole motor operatingat 50 Hz.It is advisable to use thermal protectors in heavy operating conditions. The table below shows technical details of fans supplied at 230Vsingle-phase. The servo-fans can be supplied both at 50Hz or 60Hz. On request forced cooling fans can be provided with different voltagesupply.BMAV series motors with forced cooling are provided with single axial servo-fan replacing the standard motor self cooling fan.Motor Type Dim X Dim Y Dim L Volt Amp m 3 /h dB (A)BASV 71BASV 80BASV 90BASV 100BASV 112BASV 132BASV 160BASV 180BASV 200BASV 2252102302702803003484314854855221071081291291421691842112112211021201291341421691902112112212302302302302302302302302302302x0.12x0.12x0.122x0.122x0.122x0.122x0.302x0.302x0.302x0.30939330030030061561561561561537373939395959595959BASV Series49
Built-in Encoder <strong>Motors</strong>Technical CharacteristicsBAE-BMEAV seriesBuilt-in Encoder <strong>Motors</strong><strong>Motors</strong> with built-in encoder represent a revolutionary component in the automation field providing OEM and end user with newopportunities and with notable economic advantages due to its user-friendly design. The range of three phase asynchronous motorswith built-in encoder has been designed specifically to offer to the end user a comprehensive choice of an already widely tested motorwith superior quality.MGM motors with integrated encoder can be divided in two different series of brake motors (BAE/BMEAV) and two series of standardmotors without brake (SAE/SMEAV). The power range starts from 0.06 kW up to 90 kW (frame size from 56 up to 280). The unitconsists of a three phase asynchronous high efficiency motor with a low moment of inertia and with the encoder located at the Non-Drive side.<strong>Motors</strong> are designed to be suitable for inverter use. Precise dynamic balancing together with an accurate motor insulation system areadopted in order to withstand electrical and mechanical stress. The mechanical coupling is the same standard motors (special shaftand flange are available on request), wirings are very simple to be made: power and electrical signal duly separated. MGM motorswith integrated encoder can be supplied in conformity with requirements of standards UL 1004 “Electric motors” and CSA C 22.2No. 100-95 “<strong>Motors</strong> and generators” (cCSAus approval).MGM provides 4 different motor series suitable to meet accurately all possible drives challenges.BAE series: asynchronous end phase fan cooled brake motors with built-in encoder and frame size from 71 up to 280. The encoderis located at the Non-Drive end side in a safe place protected by a well closed cover. Forced ventilation is available on request. Themotor is provided as standard with separate brake supply. The brake coil is AC as standard, while DC is available on request.BMEAV series: asynchronous three phase brake motors with DC brake with axial forced ventilation, built-in encoder and frame sizefrom 63 up to 160. The encoder is located at the Non-Drive end side between the brake and the servo fan. The motor is supplied asstandard with separate brake supply. Side manual return brake release is available on request.SAE series: asynchronous three phase fan cooled motors with built-in encoder and shaft heights between 71 mm and 280 mm. Theencoder is located at the Non-Drive end side in a safe place protected by a well closed cover. On request it’s available with forcedventilation.SMEAV series: asynchronous three phase motors equipped with forced ventilation with built-in encoder and frame size from 71 upto 280. The encoder is located at the Non-Drive end side inside the fan cover between the motor and the forced cooling fan.EncoderThe encoder is a rotational transducer to convert an angular movement into a series of electrical digital impulses. Usually the encodersused on MGM motors are based on the working principle of the angular movement transduction. The reading system is based on therotation of a radial graduated disc formed by opaque windows alternated with transparent ones. This system is all illuminated inperpendicular way by an infrared light source, so the light projects the disc image on the surface, which is covered by a grating, havingthe same step as the disc.The receiver converts the light variations occurring with the disc shifting into their corresponding electrical variations. Incrementalencoder position is determined by the number of impulses from the zero index. Absolute encoder position is determined by an outputposition code which is univocally determined within each encoder revolution. To identify exactly the needed incremental encoder, thefollowing characteristics have to be indicated:- Resolution- Impulse of Zero- Power supply- Electronic output configurationTo identify absolute encoders are additionally required:- <strong>Co</strong>de- Single turn or Multi turnThe output cable is provided as standard without connector (floating cable). On request a connector can be supplied.Please contact MGM for further information.<strong>Co</strong>olingMotor cooling is usually assigned to the motor self-cooling fan (BAE and SAE series). BMEAV and SMEAV series are forced coolingmotors.

Built-in inverter motorsBuilt-in inverter motors consist of three-phase asynchronous electric motors with integrated frequency inverter. Power range isbetween 0,37 kW and 15,0 kW while the motor frame is from 71 up to 160. The unit is made up of a high-efficiency 3-phaseasynchronous electric motor and a compact frequency inverter placed at the non-drive motor end. The basic construction is totallyenclosed, fan cooled (TEFC) and IP 55 protection degree. Built-in inverter motor is able to properly run also under heavy overloadconditions thanks to a high thermal reserve; the insulating materials are class F. The frame is made of aluminium alloy up to 132frame size and of cast iron for above sizes. Shields and flanges are made of aluminium up to 90 frame size and of cast iron up to160 frame size. The inverter housing is isolated from the motor in order to avoid heat transmission (patented system); the inverterheat sink is self-ventilated. The frequency converter provided is one of the most advanced in design concept as well as usedcomponents; control can be chosen between V/F type (frequency voltage control) or SLV type (Sensorless Vector <strong>Co</strong>ntrol). Built-ininverter motors are easy to be programmed using only three buttons. Some functions, which automatically set parameters(acceleration/deceleration times, V/f ratio etc.), make the programming easier. On request, motor can be arranged for main Bus fields(Profibus, Interbus-S, Device-Net, etc.). Built-in inverter motors are designed to be real built-in frequency converter motors and notjust as a simple assembly of a standard motor with an inverter. The wiring connection is definitely simple to be made. All the adductedfeatures make the built-in inverter motor series high performance with strong structure.General CharacteristicsBenefit and ApplicationsBuilt-in inverter motors represent an innovation in the automation field and they give manufacturers, automation designers andmachinery users new opportunities and great economical advantages. The ease of installation, the simple structure and the costeffectivenessof the system are pointed out as follows. Overall dimensions are extremely reduced; the couplings are the same of thoseof a standard motor (special flanges and shafts can be supplied on request); protection class is IP 55 as standard (IP 56 is availableon request); electrical connections are extremely simplified; power and control are totally separated and placed on different terminalboards; on request, motor can be equipped with built-in EMI filter (class A or B) in the way to avoid an external filter application; themotor connection can be carried out through normal power supply cables, as shielded cables are no longer necessary in order tocomply with EMC regulations; SMI series motor can replace a mechanical speed variator, offering more advantages; the systemperformance is very high in every operating condition; unit switchboard on which SMI motor is installed can be removed or reducedas the inverter has no longer to be housed. SMI motor represents the solution to the actual needs related to automation systems whereactuating and surveying devices can find more places on unit board so to reduce the panel overall dimensions and the wiring costs.53
