Large High-Speed 2-Pole Synchronous MotorsTMEIC builds a range of custom designed,high-speed, high-power synchronous motors fordriving large compressors.The example on the left shows a 25 MWsynchronous motor designed for variable speedoperation from 2,500 to 3,780 rpm with a 7 kVvariable frequency drive.Other TMEIC designs are available for synchronousmotor top speeds up to 6200 rpm. This can allowlarge compressors to be driven without a gearbox.High Speed 25 MW 3,780 rpm Synchronous MotorPower Design – Motor Feature output levels up to 80 MW (107,200hp) are available, and speeds up to 6,200 rpm whenused with a matched variable frequency drive suchas the TMEIC TMdrive ® -XL85.Rotor – The rotor is a two pole, cylindrical designwith a shaft mounted brushless exciter.Bearings and Maintenance – Oil lubricated sleevebearings are used. No slip rings are required withthe brushless exciter.Quality Manufacturing and Standards – TMEIC’smotor manufacturing is certified to ISO 9001 andISO 14001. Motors can be certified by third partyagencies such as CSA Lloyd’s and Baseefa. Motorscan be designed to international standards such asIEC, NEMA, BS, and AS.Power 60 HZ 15 MW (20,100 hp) up to80 MW (107,200 hp)Supply VoltageEnclosureClassified AreasMotor SpeedInsulation Class3.3 kV to 13.8 k VTotally Enclosed Water to AirCooled – TEWAC/IP55Exp certification for use inhazardous ares Zone 1 & 2,using an internal pressurizationsystemUp to 6,200 rpmClass FAir-water HeatExchangerMotor Cooling uses a water-air heatexchanger with two shaft-mountedfans forcing cool air inwardsthrough the rotor and windingsStator CoilsCooling FanStator CoreCylindrical RotorHigh-Speed Synchronous Motor – Internal DetailsOil-fed Sleeve BearingBrushless Exciter has arotor mounted three-phasewinding, which feeds highreliability diodes on the shaftsupplying DC power to therotor field winding.9

Generators – Diesel and Turbine DrivenTMEIC produces a range of high-quality, customdesigned generators for power by turbines ordiesels. The four-pole designs provide powerlevels up to 50,000 kVA with 50 or 60 Hzfrequency at 1500 rpm or 1800 rpm. Higherspeed two-pole generators provide powerlevels up to 100,000 kVA.Reliability - All generators are built in the sameplant as, and to the same high standards as thelarge motors. Manufacturing procedures to obtainthe highest reliability include Vacuum PressureImpregnation of the insulation, employing a forgedrotor with integral pole bodies for the maximumshaft rigidity and higher critical speed, and accuraterotor shaft balancing.1 Rotor Shaft 10 Frame2 Bracket 11 Air Cooler Cover3 Bearing With Insulation 12 Air Cooler4 Fan 13 Stator Core5 Fan Guide 14 Stator Coil6 Main Terminal Box 15 Exciter Support7 Rotor Coil 16 Rotary Rectifier8 Pole Head 17 AC Exciter9 Rotor Coil Bracket 18 PMGMaintenance - Easy maintenance is realized usinga brushless AC exciter with a permanent magnetgenerator. The oil-fed sleeve bearings employa floating labyrinth seal to prevent leakage, andpositive internal pressure to prevent oil enteringthe generator.The cutaway drawing in the upper left shows atypical four-pole generator with top mounted aircooler and water heat exchanger.TM21-TGTypeTwo-pole, 5,000 to 100,000 kVA powerTypeFour-pole, 10,000 to 50,000 kVA powerRotorSolid cylindrical rotorRotorSalient pole solid rotorVoltageRated 11 kV, 13.8 kVVoltageRated 6.6, 11 kV, 13.8 kVSpeed3,000 rpm or 3,600 rpmSpeed1,500 rpm or 1,800 rpmFrequency50 or 60 HzFrequency50 or 60 HzPower Factor85% laggingPower Factor80~90% laggingEnclosureTotally enclosed, water to air cooled(TEWAC)EnclosureTotally enclosed, water to air cooled(TEWAC)InsulationRating F-Class insulationInsulationRating F-Class insulationExcitationBrushless exciter with PMGExcitationBrushless exciter with PMGBearingsSleeve bearings, oil lubricatedBearingsSleeve bearings, oil lubricatedOil0.1 Mpa bearing pressureOil0.1 Mpa bearing pressure10

Hazardous Area ProtectionTypes of Explosion Protected MachinesTMEIC provides motors with different levels of explosion protection for a range of operating environmentsfound in the process industries, in particular the Oil & Gas industry. Protection in dust environments, Zone 22,is available as ExtD according to IEC61241-1.Exn –Non-SparkingMachines which, in normal operation, are not capable of igniting asurrounding explosive atmosphere.Exe –Increased SafetyMachines that do not produce dangerous sparks or temperatures innormal service or starting. Special increased safety measures are taken.Exp –Inner PressurizedExplosive gas is excluded from the inside of the machine that maycause ignition. The motor housing is pressurized with air to ensureno gases enter.Exd –Flame ProofEnclosureMachines are constructed to contain an internal explosion and preventthe transmission of flame to the external atmosphere. The temperatureof operation is such that it cannot ignite the surrounding gas.Global Protection and CertificationExplosion protection certification for TMEIC’s motors has been obtained in most areas of the world,as illustrated in this table.USA UK Europe China Korea Russia Australia Canada OthersStandard NEC ENEN +ATEXGBIEC orKSIEC orASIEC orGOSTCSAIEC or ENCertificationBodyFM, UL,etc.BaseefaBaseefa,PTB, etc.CQST KOSHA CCVETestSafeorBaseefaCSABaseefaRecordsExdExpExeExnExdExpExeExnExdExpExeExnExdExpExeExnExdExpExeExnExpExnExdExnExdExpExeExn11
