MISSION AND COMPANY HISTORYMISSION STATEMENTElinco brings world class motor design together with state of the art manufacturingand just in time delivery to achieve high satisfaction for each and everycustomer.COMPANY HISTORYElectric Indicator Company (ELINCO) was founded in 1926 in Stamford,Connecticut to manufacture instruments and controls for electric utility companies.It entered the specialty fractional horsepower motor business around the beginningof World War II and has been designing and manufacturing high performanceprecision electric motors in Connecticut ever since. The company moved toWilton Connecticut in 1962, and then to Norwalk, Connecticut in 1973, and again toFairfield and Bridgeport Connecticut in 2000, where it currently resides. The plantis a clean, well maintained facility, operated by an experienced staff, dedicated toproducing customized motor designs to the highest quality standards.ELINCO pioneered the development of the Hysteresis Synchronous motorand was a leader in this technology. In the early 1980’s, ELINCO recognized theinherent advantages of brushless DC motors and developed the slotless brushlessDC motor, which gives unique performance advantages over conventional brushlessDC motors (see “Why Slotless Whitepaper” at www.elincoinc.com). This hasresulted in a strong proprietary and patented position with “slotless” brushless DCmotor technology. The company has produced hundreds of variations of slotlessbrushless DC motors.ELINCO acquired the General Electric SELSYN (self synchronous) motorline in 1993. In 1994 ELINCO acquired the Inertial motor product line and relocatedthe line from Doylestown, Pennsylvania to the Norwalk plant. The Inertialproducts have extremely low inertia and are able to accelerate to 5000 RPM in lessthan one millisecond. In 1994 ELINCO acquired a part of the Philips Airpax motorline.ELINCO’s overall product lines now includes Slotless Brushless Motor (formwound and random wound), Custom Air Moving Devices, and Brushless Motorsover 2500 RPM.Elinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

SMALL BRUSHLESS DC MOTORSPrinciples of OperationThe differences between a DC motor having a mechanical commutation system and a BLDC motor aremainly found in :• the product concept• the commutation of phase currents.From the user’s point of view, brushless DC motors follow the same equations as those with brushes:torque is proportional to current; speed depends on the voltage and the load torque.The commutation of brushless motorsIn the conventional DC motor commutation takes place mechanically through the commutator-and-brushsystem. In a BLDC motor, commutation is done by electronic means. In that case the instantaneous rotorposition must be known in order to determine the phases to be energized.The angular rotor position can be known by:• using a position sensor (Hall sensor, optical encoder, resolver)• electronically analyzing the back-EMF of a non-energized winding. This is called sensorless commutation.Use of Hall sensorsIn general, BLDC motors have three phase windings. The easiest way is to power two of them at a time,using Hall sensors to know the rotor position. A simple logic allows for optimal energizing of the phases asa function of rotor position, just like the commutator and brushes are doing in the conventional DC motor.Use of an encoder or resolverThe rotor position may also be known by use of an encoder or resolver. Commutation may be done verysimply, similar to the procedure with Hall sensors, or it may be more complex by modulating sinusoidalcurrents in the three phases. This is called vector control, and its advantage is to provide a torque ripple oftheoretically zero, as well as a high resolution for precise positioning.Use of Back-EMF analysisA third option requiring no position sensor is the use of a particular electronic circuit. The motor has onlythree hook-up wires, the three phase windings are connected in either triangle or star. In the latter case,resistors must be used to generate a zero reference voltage. With this solution the motor includes no sensorsor electronic components and it is therefore highly insensitive to hostile environments. For applicationssuch as hand-held tools, where the cable is constantly moved, the fact of just three wires is anotheradvantage.The functioning of a sensorless motor is easy to understand. In all motors, the relation of back-EMF andtorque versus rotor position is the same. Zero crossing of the voltage induced in the non-energized windingcorresponds to the position of maximum torque generated by the two energized phases. This pointof zero crossing therefore allows to determine the moment when the following commutation should takeplace depending on motor speed. This time interval is in fact equivalent to the time the motor takes tomove from the position of the preceding commutation to the back-EMF zero crossing position. Electroniccircuits designed for this commutation function allow for easy operation of sensorless motors.As the back-EMF information is necessary to know the rotor position, sensorless commutation doesn’twork with the motor at stall. The only way of starting is to pilot it at low speed like a stepper in open loop.8Elinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

Remember:- for commutation, position sensors are necessary when operating in incremental mode-sensorless commutation is recommended only for applications running at constant speed and load.Operating principle of BLDC motors:It follows the same equations as the DC motor using mechanical commutation except that parameterslike iron losses and losses in the drive circuit are no longer negligible in applications where efficiency is ofprime importance.Iron lossesThey depend on speed and, in the torque formula, may be introduced as viscous friction. The equation foruseful motor torque becomes:M m= k·l m– k v·ω-M fWith M m= motor useful torquek = torque constantl m= motor currentk v= viscous coefficient for iron lossesω = angular velocityM f= bearing frictionLosses in the electronicsThe current and voltage required by the motor and the drive circuit to be operated at the desired speedand torque depend also on the drive circuit.As an example, a driver bridge in bipolar technique will reduce the voltage available at the motor terminalsby about 1.7V, and the total current must include the consumption of the circuitry.BLDC MOTORS SLOTLESS BLDCSTEPPING MOTORSElinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

SLOTLESS BRUSHLESS DC MOTORSWhat is an Elinco slotlessbrushless DC (SBLDC) motor?An Elinco slotless brushless DC (SBLDC) motorconsists of a stator winding positioned inside alaminated stator ring (without conventional teeth)and a permanent magnet motor. This providesmore peripheral space for the stator winding.This also allows more magnet surface area andux. Powerful rare earth magnetsprovide high torque to motor weight ratios. Theabsence of stator teeth enables more copperwinding and power density which can developmore torque. It also eliminates torque coggingand minimizes audible noise.When others say they can't, wesay we can... and do!Whether the issue is speed, power, weight, size,ciency, noise, torque ripple, heat rise, etc.,each or all are optimized to achieve customperformance with relatively short design andresponse time.Tooling charges for custom prototypes arenominal.

STEPPING MOTORSFeatures of SteppingMotorsIn stepping motors, angle of rotation is proportionalto the number of input pulses.In stepping motors, the angle of rotation per step (stepangle) is determined depending on their construction,and, for a given number of pulse signals, the angle ofrotation is proportional to the step angle. For example,in order to make a stepping motor of 1.8 degree stepangle rotate by 90 degrees, the number of pulse signalsrequired is obtained as N= 50 from the equation of1.8 X N = θIn general, it is put as:θo X N = θwhere θo : Step angle (deg./step)N : Number of input pulsesθ : Angle of RotationAngular error per one step is small, and errors arenot accumulated.Angular error per step (static angular error) is as smallas plus/minus 5%. Because this error is not accumulated,even if rotors are rotated continuously, the error isstill plus/minus 5% of the step angle.Characteristics of response to starting/stopping areexcellent.Thanks to the excellent response characteristics of thestarting/stopping signals in self-starting area (region),stepping motors can reverse their rotation instantaneously.Starting and stopping can be done simply bysending pulse signals into the drive circuit or not, andfurther, rotation reversal can be made only by changingthe input port of pulse signals to CW or CCW. However,acceleration and deceleration time must be taken intoaccount because slow-up and down control is needed inthe slew region.Very low synchronous speed is obtainable underdirect coupling of motor shaft.Stepping motors can be driven at very low synchronousspeed by widening the pulse intervals from the pulsegenerator without using a reduction mechanism suchas gear train. It not only simplifies the system, but alsoeliminates errors such as gear back-lash.Stopping position can be maintained by holdingtorque.Stepping motors have a large holding torque whenwindings are excited. In the PM type and HB motorswhich have a permanent magnet, rotors have a holdingtorque (detent torque) even in the unexcited condition.Excellent Controllability is obtained in open-loopcontrol.In DC servo motors, speed and/or positioning is controlledby sensing the motor operation with an encoder ortachogenerator, but in stepping motors, control reliesonly on pulse signals from a pulse generator. Therefore,no sensor and operating circuit are needed.GlossaryVariable Reluctance type stepping motorsThis type of stepping motor has a construction consistingof a rotor of magnetic material in the shape of a gearand an excited stator. Attraction between these partsgives the motor rotation. Step angle accuracy is high,but output torque is rather poor.Permanent Magnet type stepping motorsThis type of stepping motor has a permanent magnetrotor, and step angle is comparatively large. This typeof motor is poorer in step angle accuracy and outputtorque compared with other types, but featured by lowcost.Hybrid type stepping motorsThis is a hybrid type of VR and PM type motors. Rotorhas teeth on its periphery and stator has also manyteeth in its inner periphery. Further, the rotor has a builtinpermanent magnet. Small step angle, high torque andhigh accuracy feature this type of motorRated voltageRated voltage in the motor specifications is set so thattemperature rise meets standard value.Rated currentThis is the current that flows in the motor when the ratedvoltage is applied. In the case of stepping motors, thiscurrent flows when motors are excited and stopped.Step angleThis is the angular displacement of the rotor when onepulse is applied.Holding torqueThis is the maximum torque which a stepping motorgenerates when it is excited at the rated voltage and anangular displacement is given from outside. This is avery important factor because it makes the foundation ofthe torque generated by stepping motors.Detent torqueThis is the torque generated in the motor with a permanentmagnet rotor such as PM type and HB type whenan angular displacement is given to the output shaftwithout excitation.20Elinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

Self-starting regionThis is the region in which motors can be started andstopped instantaneously.Pulse rateThis is the number of pulses in a unit time, and is shownin the unit “pps” which means “pulses per second.” Therelation between pulse rate, speed (rpm) and angularvelocity (rad/s) is given as below.Pull-outThis means coming out of synchronized operation bybeing unable to follow the pulse signal from the pulsegenerator. Over-loading is the general cause, but noise(Electric/ Electro-magnetic) is a cause in some cases.Slow-up/slow-downIt is a kind of control to raise pulse rate to drive steppingmotors in the slew region to make them exhibit theircapability to the fullest. Among various methods, anexample of trapezoidal driving is shown in Fig. 2.where ω : Angular velocity (rad/s)π : Circular constantθs: Step angle (deg.)N : Speed (rpm)P : Driving pulse rate (pps)Maximum self-starting frequency (pps)This is the maximum pulse rate in the self-starting region.Care must be taken, because it varies dependingon the load inertia.Slew RegionIn this region, driving is possible only by slow-up/ slowdowncontrol.Maximum response frequency (pps)This is the maximum pulse rate in the slew region.Pull-in torqueThis is the torque generated when started in the selfstartingregion, and it is also called “synchronizationtorque.”Resonance phenomenonWhen stepping motors are driven, torque decrease, missteps,vibration, and other unfavorable phenomena mayoccur at some specific frequencies. It is called “Resonancephenomenon,” and is caused by the coincidenceof intrinsic vibration frequency and input pulse frequencyof the motor. It is experienced generally in the range of100 to 200 pps. It is impossible to eliminate this resonancefully, but the defect can be reduced by changingexcitation mode or providing a damper.BLDC MOTORS SLOTLESS BLDCSTEPPING MOTORSPull-out torqueThis is the torque generated when driven in the slewregion.Elinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

Basic Characteristics ofStepping MotorsDynamic characteristic of stepping motorTORQUE-SPEED characteristicsFig. 21 shows the relation between torque and rotatingspeed of stepping motor. When stepping motors aredriven in the self-starting region, they can be started orstopped instantaneously by sending necessary pulsesignals into the drive circuit. Stepping motors have a“Slew Region” in their operating range. In this region,stepping motors can be operated at high synchronousspeed at their full capacity. To bring stepping motors intothis running region, they must be started at first in theself-starting region and then the pulse rate is increasedgradually in a short time by slow-up/slow-down control.wherePL : Max. self-starting frequency with load inertia(pps)Ps : Max. self-starting frequency of motor only (pps)JP : Moment of inertia of rotor (oz-in 2 )JL : Moment of inertia of load (oz-in 2 )TRANSIENT RESPONSE characteristicsThe rotor of a stepping motor stops at a stable point(theoretical stop point) after repeating attenuation vibration.This is a very important characteristic because itaffects vibration, misstep, stopping time and others. It isalso affected by the motor construction, exciting mode,load conditions, etc. Therefore, it must be reviewedcarefully in motor design.1) Rise-up timeIt is the time needed for the rotor to reach the stepangle for the first time after a pulse signal is applied.2) Settling timeThis is the time from application of a pulse signal tothe stop of rotor after attenuation of rotor vibration.PULSE-INERTIA characteristicsStepping motors do not rotate smoothly at constantspeed like induction motors and DC motors, but repeatstart, acceleration, deceleration and stop. Such characteristicsof motion are heavily affected by the momentof inertia of the load. As the load inertia increases, theself-starting region is narrowed. The maximum selfstartingfrequency of stepping motors with load inertia isexpressed approximately by the following equation.Static characteristics of stepping motorsStep angle accuracyThis is the error for the theoretical rotating angledetermined by the exciting mode adopted or mechanically.This error may be caused by the dispersion ofmechanical accuracy and winding resistance. It includes(1) Positional accuracy, (2) Stop position error and (3)Hysteresis error.1) Position accuracyStarting from any one point, the rotor is rotated onestep by one step through 360 degrees. An angularerror between the theoretical position and actualposition for every step is measured through 360degrees. One half of the difference of maximumpositive error and maximum negative error is called“Positional accuracy,” which is shown below.22Elinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

An angular errorbetween the theoretical position and actual positionfor every step is measured through 360 degrees.The maximum angular error for one step amongthem is called “stop position error” which is shown asbelow.orwhere Es : Stop position error (%)+Δαi : Max. positive value (degree)[ θ(i+1) - θi ]-Δαj : Max. negative value (degree)[ θ(j+1) - θj ]3) Hysteresis errorStepping motors have some discrepancies in thestop positions in CW and CCW rotation. This error iscalled “Hysteresis error,” and the maximum discrepancybetween both rotations is taken in general.Angle-Static torque characteristicsIn an excited stepping motor with its rotor held at a stopposition, when external torque is applied to the outputshaft to give angular displacement to the rotor, the relationbetween the angular displacement and the restoringtorque is called “Angle- Static torque characteristics.”Some difference is found depending on the motor constructionand exciting mode, but it is expressed approximatelyby the Equation (1) and (2)-----------------------------(1)BLDC MOTORS SLOTLESS BLDCwhereθs : Step angleTm : Holding torqueθ : Angular displacement------------------------(2)STEPPING MOTORSElinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

Actions for VibrationReduction of SteppingMotorsThe biggest problem in the use of stepping motors is“Vibration.” In this section, kinds of vibration and actionsfor the improvement are explained.Vibration caused by resonanceThis is the vibration generated when the naturalfrequency of motor coincides with the input pulsefrequency. The range of 100 to 200 pps is where it isgenerated, and, in some cases, the motor will pull out ofthe synchronous speed.Vibration at low speed operationStepping motors rotate by repeating start and stop inevery step angle. Motor behavior is the repetition ofattenuation vibration, which generates large vibrationnaturally at low speed.4) To provide mechanical damperThis is a method of absorbing vibration by applyingmechanical braking force from outside. Mechanicaldampers include friction damper, flywheel damper,viscous damper and magnet damper.5) To provide electrical damperThis is a method to absorb vibration energy bychanging the condition of the surge absorbing circuitin the output stage of driver. A typical example iscapacitor damper.Capacitor damperIn this method, a capacitor is inserted between everyphase. Using the electro-motive force at ON/OFF oftransistors, a certain amount of current is applied tothe windings, which were released from excitation, forbraking. In this method it must be noted that torque isdecreased at high speed.Vibration at medium and high speedsThe attenuation vibration of stepping motor is shown inFig. 26. The over shoot in Fig. 26 affects the vibration atmedium and high speed.Actions for improving vibrationThe following actions are taken for the improvement ofvibration.1) To operate at a frequency out of resonance frequencyIn driving stepping motors, the frequency must beset basically out of resonance frequency range of100 to 200 pps.2) To change excitation modeBy changing the excitation mode to 1-2 phase excitation,the step angle is halved, resulting in smallervibration at low speed.3) To change load torqueBy increasing load torque, especially frictionaltorque, vibration energy is absorbed to reduce vibration24Elinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.

APPLICATION NOTICESTemperature riseHeat radiation of the motor must be considered whenthe motors are driven. Heat generation of the steppingmotors is generally higher than others depending on thevarious conditions. Please do not allow the temperatureof the motor housing to exceed 212° F (100 ° C).Direction of rotationThe direction of rotation is defined in the catalogue asviewed from the front of the mounting fac`e.Measuring the temperature of the motor:Thermometer methodThe temperature of the motor is measured by using athermometer or thermocouple attached to the center ofthe motor housing, after the temperature rise becomessaturated.Calculation methodThe temperature of the motor winding can be calculatedby the following formula.Temperaturet [°C] : Ambient temperatureΔ t [°C] : Temperature riseR 1[°C] : Winding resistance of the motor at theambient temperatureR 2[°C] : Winding resistance of the motor afterthetemperature risebecomes saturated.In case of this method, the winding temperature T °Cmust not exceed the allowable temperature of the motorinsulation class.Installation of the motorsMounting directionAny direction is not restricted in the installation of themotor, but usually mounting motors sideways is recommended.Regardless of the mounting direction, pleasetake care with the overhung load and thrust load on theshaft, and also free it from any shocks on the shaft.Heat dissipationThe temperature rise of stepping motors is relativelyhigh; please mount the motors tightly on the metalsurface with good thermal conductivity such as steel oraluminum by the screw and nut with a spring washer forthe heat dissipationNoise reductionA stepping motor itself easily generates vibration due tothe oscillatory step operation of the rotor even when themotor is driven at a high pulse rate, and when this vibrationis harmonized with the mounting plate, vibrationnoise is amplified and causes high acoustic noise. Inthis case, please reconsider the drive frequency and/orthe thickness and material of the mounting plate or drivingmethod. When the temperature of the motor seemslow, a rubber plate can be used effectively between themotor mounting face and mounting plate for the vibrationabsorption.Alignment of the loadWhen the motor drives a load by coupling directlyboth axes of the motor and load, please use a flexiblecoupling ring or other suitable items to make sure it getsaligned properly. Otherwise, vibration will be caused andthe life of bearings will be shortened.BLDC MOTORS SLOTLESS BLDCSTEPPING MOTORSElinco International Inc. 1525 Kings Highway East, Fairfield, Ct 06824Ph.
