摘　　要：双凸极电机的径向磁吸力是电机产生振动与噪声的主要来源。该文运用有限元方法,对1台双凸极结构的开关磁阻电机进行了径向磁吸力的计算,得到了径向磁吸力与转子位置角及相电流的关系。其结论为描述双凸极电机径向磁吸力的非线性模型奠定了基础,同时对于设计优化电机结构以减小振动与噪声有较好的指导意义。The radial magnetic force is the primary source of vibration and noise in doubly-salient motor. This paper utilized finite element method to compute the radial magnetic force of a switched reluctance motor wihch is a kind of doubly-salient motor. The relationship between the radial magnetic force with the rotor position and phase current were obtained, which laid a foundation for describing non-linear model of radial magnetic force. It＇s instructive to optimize the design of motor to reduce the vibration and nosie.
