摘　　要：根据稀土永磁同步电动机稳态运行时转子温升问题,对稳态运行时电机转子铜耗进行理论分析,利用有限元磁场分析软件对实际研制的稀土永磁同步电动机进行了仿真分析,计算出实际稳态转子铜耗。最后用实验验证了磁场仿真结果的正确性,证明了稳态运行时稀土永磁同步电动机实际存在转子铜耗。According to the heat problem in practical design of rare earth permanent magnetic synchronous motor, a point of view about the existence of copper losses in the rotor of rare earth permanent magnetic synchronous motor for true is presented. Copper losses of the rotor is analyzed theoretically. The result of analysis is simulated by the magnet software and validated by the experiment data of the motor test. The correctness of viewpoint is verified finally.
