Abstract：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.
