摘要

针对电动汽车驱动电机在整车极限工况下的温升问题,采用流-固共轭传热数值计算方法对永磁同步电机的散热性能进行了仿真计算,得到了不同工况下电机定转子的温度分布规律。利用滑环模块解决了转子温升测试的难题,将不同整车工况下电机的温升测试数据和计算流体动力学(CFD)仿真结果对比,验证了仿真计算模型及方法的准确性,为整车在各种行驶路况下准确获取电机内永磁体工作温度提供了理论支持。
        Aiming at the temperature rise problem of drive motor for electric vehicle under extreme conditions, the numerical method of fluid-solid conjugate heat transfer was used to simulate the heat dissipation performance of a permanent magnet synchronous motor. The temperature distribution of the stator and rotor under different working conditions was obtained. The slip ring module was used to solve the problem of rotor temperature rise test. The data of temperature rise test and computational fluid dynamics(CFD) simulation results of different vehicle conditions were compared to verify the accuracy of the numerical model and method. This research provided theoretical support for accurately obtaining the operating temperature of permanent magnets in the motor under driving conditions.
