전동차 AC 견인전동기의 가속열화에 관한 연구

초록

In this paper, the diagnois 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 dor stator of traction motor were tested by accelerative thermal dagradation which composed of heat, vibration, vibration, moisture, and overvoltage applying. Reliability and expected life were evaluated on the insulation system for 200 class traction motor.
