Motors for EU motor efficiency levelsA Europe-wide agreement willensure that the efficiency levelsof electric motors manufacturedin Europe are clearly displayed. Incontrast to the American legislationon motor efficiency the Europeanagreement does not establishmandatory efficiency levels.It basically establishes three classesgiving motor manufacturers anincentive to qualify for a higherclass.ABB is one of only a handful ofleading motor manufacturers inEurope to have a motor rangeto meet or exceed the minimumefficiencies stated in the highestlevel of the EU agreement of LVmotors.These efficiency levels apply to2- and 4-pole, three phase squirrelcage induction motors rated for400V, 50Hz with S1 duty class withthe output 1.1 to 90 kW, whichEU efficiency classes for 2-pole .693.9account for the largest volume onthe market.The efficiency of motors fromdifferent manufacturers are collatedin a database, EURODEEM,published by the EuropeanCommission.

InsulationABB uses class F insulation systems, which, withtemperature rise B, is the most common requirementamong industry today.1The use of Class F insulation with Class B temperaturerise gives ABB products a 25 C safety margin. This canbe used to increase the loading for limited periods, to operate at higher ambient temperatures or altitudes, or withgreater voltage and frequency tolerances. It can also beused to extend insulation life. For instance, a 10 K temperature reduction will extend the insulation life.Class F insulation system– Max ambient temperature 40 C– Max permissible temperature rise 105 K– Hotspot temperature margin 10 KClass B rise– Max ambient temperature 40 C– Max permissible temperature rise 80 K– Hotspot temperature margin 10 KInsulation system temperature class– Class F 155 C– Class B 130 C– Class H 180 CSafety margins per insulation class8ABB LV Motors / Cat.

Frequency converter drivesSquirrel cage induction motors offer excellentavailability, reliability and efficiency. With a frequencyconverter – a variable speed drive (VSD) – the motorwill deliver even better value. A variable speed drivemotor can be started softly with low starting current,and the speed can be controlled and adjusted to suitthe application demand without steps over a widerange. Also the use of a frequency converter togetherwith a squirrel cage motor usually leads to remarkableenergy and environmental savings.However, all motors are not suitable for variable speeddrive. There are several points that have to be taken intoaccount in the design and selection of the motor, if it isintended for variable speed operation.Within the General purpose motor range ABB offersmotors designed for both Direct On Line (DOL) andvariable speed applications.For more demanding applications the use of ABBProcess performance motors is recommended.The following points must be taken into account, whenselecting a motor to a variable speed drive:1. DimensioningThe voltage (or current) fed by the frequency converteris not purely sinusoidal. This may increase the losses,vibration, and noise of the motor. Furthermore, achange in the distribution of the losses may affect to thetemperature rise of the motor. In each case, the motormust be correctly sized according to the instructionssupplied with the selected frequency converter.When using ABB converters, please use ABB'sDriveSize dimensioning programme or the loadabilitycurves of the corresponding converter type for sizingthe motors. The loadability curve for applicable Generalpurpose motors used with ABB's ACS 600- and ACS800- frequency converters can be found in figure 3.2. Speed rangeIn a frequency converter drive, the actual operatingspeed of the motor may deviate considerably from itsnominal speed (i.e. the speed stamped on the ratingplate).For higher speeds, ensure that the highest permissiblerotational speed of the motor or the critical speed of theentire equipment is not exceeded. When high speedoperation exceeds the nominal speed of the motor, thefollowing points should be checked:– Maximum torque of the motor– Bearing construction– Lubrication– Balancing– Critical speeds– Shaft seals– Ventilation– Fan noiseGuideline values of maximum speeds for M3AA motorswithin the General purpose motor range are describedin figure 1 below. Exact values are available on request.Figure 1. Guideline values of maximum speeds for Generalpurpose motor in aluminium frame:Motor sizeSpeed r/min2-pole4-poleM3AA 90-100M3AA 112-200M3AA 225-280600045003600600045003600At low speed operation the motor’s ventilation fanlooses its cooling capacity, which causes a highertemperature rise in the motor and in the bearings. Aseparate constant speed fan can be used to increasecooling capacity and loadability at low speed. It is alsoimportant to check the performance of the grease at lowspeeds.3. LubricationVariable speed operation affects on the bearingtemperature, which must be taken into account whenselecting the lubrication method and grease type.For example the life time of sealed bearings can beremarkably shorter than in direct on line operation. Moreinformation can be found from product specific sectionsof this catalogue and from ABB’s Low Voltage MotorsManual.4. Insulation protectionFrequency converter supply causes higher voltagestresses at the windings of the motor than thesinusoidal supply. Thus, the insulation system andpossible filters must be selected according to the usedvoltage, cable length and converter type.When using ABB’s low voltage frequency converters,selection criterias mentioned in figure 2 must befollowed.5. Bearing currentsBearing voltages and currents must be avoided in allmotors. Assuming the use of ABB ACS 800 or ACS 550drive, with uncontrolled DC-voltage, insulated bearingsand/or properly dimensioned filters at the converteroutput must be used according to the instructions infigure 2. (For other alternatives and converter types,please contact ABB.) When ordering, clearly statewhich alternative will be used.For more information about bearing currents andvoltages, please contact ABB.ABB LV Motors / Cat. BU / Low Voltage General Purpose Motors GB 12-200491
6. Cabling, grounding and EMCThe use of a frequency converter puts higher demandson the cabling and grounding of the drive system. Themotor must be cabled by using shielded symmetricalcables and cable glands providing 360 bonding(also called EMC-glands). For motors up to 30 kWunsymmetrical cables can be used, but shielded cablesare always recommended.“Grounding and cabling of the drive system” (Code:3AFY 61201998 R0125 REV A) and the ABB’s LowVoltage Motors Manual.For fulfilling the EMC requirements, special EMCcable(s) must be used in addition to the correct cablegland mounting, with special, extra earthing pieces.Please refer to the manuals of the frequency converter.More information about grounding and cabling of avariable speed drive can be found from the manual1ValidityMeasures mentioned in Figure 2 apply to the applicable motors within the General motors range (not high-outputversions) with ACS 800 and ACS 550 drives with uncontrolled DC-voltage. For other alternatives and convertertypes, please contact ABB.Figure 2.

DU/dt -filter decreases the changing rate of the phaseand main voltages and thus reduces voltage stresses in the windings.DU/dt -filters also decrease so-called common mode currents and therisk of bearing currents.Common mode filtersCommon mode filters reduce so-called common mode currents inVSD applications and thus decrease the risk of bearing currents.Common mode filters do not significantly affect the phase or mainvoltages on the motor terminals.Insulated BearingsBearings with insulated inner or outer races are used as the standardsolution. So-called hybrid bearings, i.e. bearings with non-conductiveceramic balls, can also be used in special applications. Moreinformation for spare part selection is available on request.Figure 3.
