INTERACTION BETWEEN CONVERTER AND VEHICLE DRIVE. CONSIDERATIONS AND RECENT INVESTIGATIONS OF THREE-PHASE DRIVES

P.K. Sattler

Abstract

The use of the three-phase induction motor drive for rail vehicles is considered. Research activities in West Germany are reported which showed that due to new cooling systems, for instance cooling by heat pipes or by water, the weight of three-phase induction motors has been reduced to 33% of the conventional 16 2/3-Hz-traction motor. The importance of oscillating torques is discussed, along with feeding of induction motors for traction with a constant current converter.
