摘　　要：电动运行时电励磁双凸极电动机存在转矩脉动的问题,特别是电流换向容易造成很大的转矩脉动。从理论上分析了电流换向过程,利用Maxwell和Simplorer软件的联合仿真验证理论结果,并采用半桥控制电路改善仿真结果,为DSEM电动机的转矩优化设计提供参考。Doubly salient electro-magnetic motor has the problem of torque ripple in the electric operation especially large torque ripple is made by current transfer easily. The current transfer process was analysized and the theoretical result was proved by using the union simulation of Maxwell and Simplorer. The simulation was improved by using half bridge cir- cuit for providing reference about the torque design optimization of DSEM.
