摘　　要：以一台50 k W永磁驱动电机为例,根据流体力学和传热学原理,利用有限体积法对电机温度场进行了研究,分析出其温度分布规律。该结果与实验所获数据相吻合,证实了计算方法和计算结果的合理性。但是为了有效地解决由于接线盒所在区域温升过高,温度梯度较大的问题,提出4种对接线盒结构的优化方案,对其不同方案下电机整体温度分布及接线盒所对应的电机内部径向区域温度场特性进行了详细地分析,所得结论为永磁驱动电机结构的优化设计提供了理论参考。A 50 kW permanent magnet drive motor was taken as an example to investigate the thermal per- formance, in order to improve the cooling effect of fluid. On the basis of hydromechanics and heat trans- fer theory, temperature field was studied using finite volume method, the temperature distribution was ob- tained, the results of temperature correspond with the measured results, and the rationality of the calcula- tion method and calculation results were verified. Therefore, in order to cool the working temperature of junction box, four optimization schemes were carried out. The temperature rise and temperature field characteristics for whole PMSM and the components which according to the junction box in axial direction were analyzed in detail. The conclusions have a significant reference for designing and optimizing the PMSM.
