■The second of two 60,000 hp (44,743 kW), 600 rpm, dual 3-phase motors (left) for the Arnold Engineering Development Center in Arnold AFB,Tennessee, U.S.A., is shown undergoing a no-load mechanical test. After testing, the 210,000 lb. (95,238 kg) wound rotor is prepared for installation ofthe coupling hub before shipment (right) in November 2003.The motors replace two 35,000 hp (26,100 kW) motors in a train of equipment that includestwo existing 83,000 hp (61,894 kW) motors connected by indexing couplings that drive a single-stage transonic compressor on one end of the train or afour-stage supersonic compressor train on the other end.The system supports both subsonic and supersonic wind tunnel testing of aircraft propulsionsystems.INDUSTRIAL MOTORS AND MORETECO-Westinghouse AttributesMany Factors to its SuccessBy Norm ShadeTECO-Westinghouse MotorCompany (TWMC) of RoundRock, Texas, U.S.A., manufactureselectric motors and generators,offering a broad selectionranging from 0.25 to100,000 hp (0.2 to 74,571 kW).In addition, said Mike Kuo,TWMC president, “We alsosupply motor controls and provideengineering services, genuineWestinghouse renewalparts and large motor repairs.Our company’s products areused to drive pumps, fans,compressors, rolling mills,grinders, crushers and a varietyof other rugged applications.”While the Westinghousename has been associatedwith electric motors since1888, the connection withTECO developed rapidly overthe last 15 years. The WestinghouseMotor Company (WMC)was established in 1988 as ajoint venture between WestinghouseElectric and TECOElectric and Machinery Co.Ltd. Under that arrangement,WMC designed and manufacturedlarge, custom AC andDC products at the RoundRock facility, while more standardizedproducts were manufacturedby TECO’s modernmanufacturing facilities inTaiwan with WMC providingdesign and technical support.WMC marketed, sold and distributedthese productsthroughout the North Americanand select internationalmarkets under the WestinghouseMotor Company name.In 1995 TECO acquired100% of the joint venture,made a significant investmentin the Round Rock facility andbegan to manufacture morestandardized products there inorder to reduce lead-time tosupport the local market.Concurrent with changing thecompany name to TECO-Westinghouse Motor Companyin 1997, TWMC formed aService Group to provideservice on TWMC and othermanufacturer’s motor and motorrelated products.In 1998 TWMC merged withTECO American, and all TECOmotor operations in NorthAmerica were consolidatedinto TWMC with the resultantexpansion of the product linesto include NEMA T-frame motorsand TECO designed motors.This gave TWMC responsibilityfor sales, marketing,and distribution for TECO ACinduction and synchronousmotors and DC motors productsin the U.S.A., rangingfrom 0.25 to 100,000 hp (0.19to 74,571 kW).TWMC manufactures abroad range of AC inductionmotors that are used in compressor,fan and pump driveapplications. The company’sfabricated steel frame inductionmotor line, ranges from250 to 30,000 hp (186 to22,371 kW) at 300 to 3600rpm in both horizontal andvertical configurations and forvoltages from 2.3 to 13.8 kV.“These high-efficiency motorscombine sophisticated designtechnology with advanced materialconstruction,” saidMichael Bachmeyer, generalmanager for engineered ACproducts. Standard features includerugged thru-bolt copperor copper alloy rotor bar constructionand end rings, formwound windings withWestinghouse-developedThermalastic epoxy Class F insulationsystem, and either antifrictionor spherically seatedRenk split-sleeve bearings.For demanding petroleumand chemical applications, theRock 541 line of custom-designedmotors is available tomeet or exceed API 541 orother specifications. For specializedindustrial applicationsrequiring induction motorswith two predeterminedspeeds and a single-winding,the company offers PAM (PoleAmplitude Modulation) motorsin sizes from 1000 to17,000 hp (746 to 12,677 kW).TWMC also offers severalstocked products includingthe Global Series of totally enclosedfan-cooled (TEFC) motorsranges in size from 150 to2000 hp (112 to 1491 kW).They are available for speedratings from 900 to 3600 rpmand either 2300 or 4160 V systems.Designed to operate in avariety of industrial environments,the Global series has arugged cast-iron frame andend brackets for rigidity andexcellent corrosion resistance.“These machines have numerousfeatures to ensure longtermperformance includingcopper rotor construction, acorrosion resistant externalfan and Class F insulation,”explained Bachmeyer. “Theyare the ideal choice when areliable induction motor isneeded in a dirty or corrosiveoperating environment.”Standard TEFC motor sizesto 900 hp (522 kW) are availablefrom stock. In addition tothe extensive Round Rockwarehouse, the company hasregional warehouses in Reno,Nevada; Allentown, Pennsylvania;and Spartansburg,South Carolina, U.S.A.
