Abstract

In this paper, the diagnosis method for AC traction motor is to reduce their maintenance loads. We tried to apply this method to maintenance of traction motor in railway vehicle. Sample coils for stator of traction motor were tested by accelerative thermal degradation which composed of heat, vibration, moisture, and overvoltage applying. Reliability and expected life were evaluated on the insulation system for 200 class traction motor.
