本文提出了一种结合动态磁阻网格模型（DRM）和改进的铁损预测模型的永磁（PM）脉宽调制电源电机铁损预测方法。建立了高速列车永磁牵引电机的DRM模型。然后使用DRM方法获得一个周期的磁场分布。采用了一种改进的铁损预测工程模型。最后，仿真和测试结果表明，所提出的组合方法是准确和有效的有限元法（FEM）模型，更少的时间消耗。
In this paper, dynamic reluctance mesh model (DRM) combined with an improved iron losses prediction model are presented to provide fast and accurate way to evaluate the iron losses for permanent magnet (PM) motors with pulsewidth-modulated power supply. A DRM model for high-speed train PM traction motor is first built. The magnetic field distribution for one cycle is then obtained using the DRM method. An improved engineering model of iron losses prediction is applied. Finally, the simulation and testing results are presented to confirm that the proposed combined method is accurate and effective as the finite element method (FEM) model with much less time consumed.
