摘　　要：本文对高功率密度轮毂电机温度场建模问题进行研究,通过热路模型理论分析给出温度场预测精度的影响因素,提出一种按损耗分布加载的精确温度场仿真方法。采用正交傅里叶分解算法对铁耗进行分析,揭示永磁电机铁耗的分布规律;结合热路模型分析以及与传统仿真方法对比,指出轮毂电机高速运行情况下采用该方法的必要性。This paper mainly investigates temperature field modeling of high power-density in-wheel motor. Theoretical analysis of thermal circuit model presents the influencing factors for prediction accuracy of temperature field. A new accurate temperature field simulation method based on loading the heat source according to loss distribution is improved. Iron-loss distribution of the permanent magnet motor is given by analyzing iron loss with orthogonal Fourier decomposition method. Based on the analysis of thermal circuit model and the comparison with traditional simulation method, this paper points this method is imperative for in-wheel motor at the condition of high speed running.
