摘　　要：利用Ansoft软件,对新型径向叠片磁阻转子的无刷双馈电机的电磁场进行了有限元计算,计算出了电机同步运行时的电磁转矩性能曲线,得到了实现最大电磁转矩控制的相位角关系和气隙磁密分布,为电机的优化设计和最优控制提供了理论指导。This paper afforded a brushless doubly fed machine （BDFM） with a novel radial reluctance rotor structure for finite element calculation of the field based on Ansoft. The maximum torque and torque characteristics were presented at synchronous operation. The phase relationships about the maximum torque control were obtained. And the distribution of the air gap magnetic density was achieved. All the results were investigated to provide the guide for the optimal design and optimal control of BDFM.
