StandardsType DesignationEMT Motors are designed, manufactured andtested to the following StandardsEMT Motors are designated by standard codes:IEC 60034-1IEC 61972 / 60034-2IEC 60034-5IEC 60034-6IEC 60037-7IEC 60034-8IEC 60034-9IEC 60034-14IEC 60072-1AS/NZS 1359.5.2004Ratings & PerformanceLosses & EfficiencyDegrees of ProtectionMethods of Coolingconstruction mountingTerminal & MarkingsNoise LimitsVibration MechanicalDimensions & OutputsMEPS2 EnergyEfficiency StandardsExample AHE 132S12 B3AHE132S12B3Aluminium FrameIf absent frame is Cast IronEnergy Efficient (MEPS2 / IE2)IEC Frame size (shaft height mm)Stator core length.1 Short, 2 Long, 3 Extra longNumber of poles2 3000rpm 4 1500rpm6 1000rpm 8 750rpmMounting arrangementB3 Foot B5 Flange B35 Foot & FlangeB14A / B14B Face mount flangeNameplatesAll EMT motors are fitted with Stainless Steelnameplates. Rating and performance data isembossed and stamped to ensure it can remainpermanently identifiableMounting ArrangementThe design of all EMT motors is such that theycan be operated in all horizontal-mountingpositions, providing consideration is given to thelocation of drain holes and bearing life EMTMotors are available in B3 foot mounted, B5flange mounted, B14A face and some B14Bmounting configurations. For confirmation ofvertical operation requirements please refer toour offices for assistance with bearing designrequirements.CoolingMotors in standard form are Totally EnclosedFan Cooled (TEFC IC411). Cooling fans ene or high pressure die cast alloy.All fans are bi-directional and fan covers arerigid pressed steel. Other cooling formatsavailable areooIE416 Forced Ventilation for VSD useIE418 Pad mount for external ventilationForced Ventilation IE416All three phase EMT Motors are suitable forInverter Duty applications. For constant torqueapplicationswhereamotoroperatescontinuously below 50% of its rated speed, aConstantVelocityCoolingUnitisrecommended, to providing continuous coolingair over the motor regardless of the output shaftspeed.EMT also recommends the fitting of insulatedbearings on motors above 90kW to eliminatecirculating currents and prolong bearing life.It should be noted that with VSD applicationswhere speed frequently exceeds 60Hz a torquedrop off may be experienced necessitating theuse of a higher kW motor, contact our officesfor recommendations in this regard.RotorsDutyAll EMT motors are Continuous Duty Ratedo(S1), based upon max ambient of 40 C andaltitudes below 1000 metres. For applicationswhere motors are required to meet duty ratingsfrom S2 to S9 please contact our offices forassistance3All rotor windings and end rings are one-piecedie cast aluminium with cooling fins to provideinternal air movement. Shafts are made fromhigh quality carbon steel. See data tables fordimensions.

BalancingTerminal BoxesRotors are dynamically balanced to severitygrade normal (N) as specified in relevant IECand Australian standards. EMT motors can besupplied with either a reduced (R) or special (S)vibration level upon request.All terminal boxes can be rotated in 90 degreesteps through 360 degrees. Metric conduitentries are provided on all motors. Refer todimension data for number and size of entries.The terminal box material on frames type AHE63 to AHE 160 is Alloy and frames HE 132 toHE 450 have Cast Iron boxes.

Class H motors are available onrequest. All designs limit rise to 80 Deg C at FLInsulation materials are divided 3 generalclasses each having a recommendedtemperature range under normal operatingconditions. Exceeding these limits will reducemotor life proportionally.Temperature Limits for variouswinding insulating classes.B130F155Special bearing arrangements can be providedto suit various applications.

Anti-Condensation HeatersTerminal Connections (Three phase)All EMT motors can be fitted with anticondensation heaters, installed around thedrive end windings these usually energisedwhen the supply to the motor is switched offHeater power ratings normally used are shownin the table below. The standard supply voltageis 220 - 240V AC but other supply voltages canbe provided upon request.All 3 phase motors have six terminals. EMTmotors are compatible for use with single-phasevariable frequency controllers up to 3kW and 3phase variable frequency controllers throughoutthe entire range.Motor Frame Size56 – 7180 – 112132 – 200225 - 280315 – 400Power( Watts )825405499DOL terminations 3KW and below are:Delta 220/240V 50Hz or 260/280V 60HzStar 380/415V 50Hz or 440/480V 60HzDOL terminations 4KW and above are:Delta 380/415V 50Hz or 440/480V 60HzStar 660/720V 50Hz or 760/830V 60HzTerminal Connections (Single phase)Thermistor ProtectionEMT motors rated at 11KW and above are fittedwith one set of 3 x PTC Thermistors embeddedinto the windings during manufacture.Thermistors can also be fitted to motors inframe sizes 63 to 132 as an option.Optional Over-Temperature ProtectionAdditional protection devices on request:Alarm Thermistors:A second set of PTC Thermistors with a lowertemperature rating, can be installed to providean over temperature alarm warning prior to anytrip activation of the main thermistorsPT100 Thermocouples:These platinum resistance thermometersprovide variable linear resistance in proportionto winding temperature. They are particularlysuitable for continuous temperature monitoringapplication requirements in windings andbearings.5See connection diagram for single phasemotors in this section.Both MY and ML Series Single-Phase motorsare suitable for applications where reversing ofdirection is required, either by simple changingof connection bridges or by use of an externalreversing switch.Motors from frame size 56 to 90 are suitable for240V 50Hz connection. Motors of frame size100 and above are Dual Voltage rated andsuitable for connection to 240V or 480V, 50Hzsingle phase supply.Single Phase Centrifugal Start SwitchCap Start/Cap Run motors utilise a solid,internal centrifugal switch plate mechanism thathas a larger diameter than the motor bearings,therefore eliminating potential damage to theswitch plate when the motor is dismantled formaintenance. The switch plates on larger MLseries motors have dual start switch contacts,making them suitable for applications that havea long run up time.
