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
