摘　　要：针对开关磁阻电机特殊双凸极结构和非线性磁饱和产生较大电磁噪声的问题,设计一台相数最少的新型结构单相开关磁阻电机。对引起电磁噪声的径向力进行计算,分析径向力的产生原理和分布情况,采用有限元仿真软件Ansoft对其进行静态和动态磁场的仿真,并从结构参数出发对定子所受径向力进行优化,从而减少单相开关磁阻电机的电磁噪声和转矩脉动。In view of problems of switched reluctance motor＇ s special doubly salient structure and nonlinear mag- netic saturation resulting in large electromagnetic noise, designed a new structural single-phase switched reluctance motor to compute the radial force which causing electromagnetic noise, and analyzed the radial force generation principle and distribution. Applied finite element simulation software Ansoft to simulate its static and dynamic magnetic field, and from structural parameters optimized the radial force on stator, thereby reducing electromagnetic noise and torque ripple of single-phase switched reluctance motor.
