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 forin-wheel motors under the continuous rating base speed condition. For conventional model #1, in which cooling oil wasstagnant 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 ofthe coil was 155.4°C. Therefore, both models proved unsuitable for in-wheel motors since the motor controlspecifications limited the maximum temperature to 150°C.
