전기자동차용 유냉식 인휠 모터의 방열 특성 연구

다국어 초록 (Multilingual Abstract)

Cooling the in-wheel motor in electric vehicles is critical to its performance and durability. In this study, thermal flow analysis was conducted by evaluating the thermal performance of two conventional cooling models for in-wheel motors under the continuous rating base speed condition. For conventional model #1, in which cooling oil was stagnant in the lower end of the motor, the maximum temperature of the coil was 221.7°C; for conventional model #2, in which cooling oil was circulated through the exit and entrance of the housing and jig, the maximum temperature of the coil was 155.4°C. Therefore, both models proved unsuitable for in-wheel motors since the motor control specifications limited the maximum temperature to 150°C.
