摘　　要：对有限元时步法在永磁电机中的应用进行了研究,阐述了基于二维场路耦合时步法的永磁电机模型。采用一台具有特殊转子磁路结构的永磁电机进行了仿真分析,结合试验结果证明了该模型的正确性并指出利用永磁电机的有限元模型结合控制策略是现代电机及其控制系统仿真的方向。Not only researches on permanent magnet motor using finite element time - stepping technique but also the PM electric machine model based on two dimensions field -circuit coupled time - stepping method are made. A PM synchronous motor with novel rotor structure is simulated as an example. Both the simulation and experimental results prove the correctness and feasibility of the computing models. It is also pointed out that using the PM motors finite element model combined with control strategies is the trend in the simulation of modern electric machine and control system.
