철도차량 성능향상을 위한 각륜구동전동기 시스템

초록

Conventional induction motor driving system using the inner and outer radius of the curved lines by the car speed difference between the wheels is pulled to one side, so that the wheel and rail wear and noise is generated, and the maintenance cost is increased. In addition, the efficiency of the induction motor is cooled by the outside air is low, foreign matter way costly maintenance due to the structure in which there is need improvement. Thus,the use of high-energy class of urban rail-curve given that a high percentage of efficiency than conventional motors and rotate each curve so that the curve of the wheel when driving to improve traceability and reduce noise and maintenance costs of the permanent magnet synchronous independent wheeltype traction motor skills need to be developed."
