摘　　要：建立了开关磁阻电机定子系统磁固耦合振动微分方程;在考虑开关磁阻电机位移场与电磁场相互作用、相互影响的条件下,利用麦克斯韦张量法和磁路法,推导出开关磁阻电机定子系统所受径向电磁力;结合梁函数组合法解得定子系统径向振动位移表达式。以一台8/6样机为例,将所求结果与二维有限元分析结果进行了对比,验证了所建模型的有效性,所建模型符合实际开关磁阻电机结构及运行特点。This paper investigates the magnetism and soldid coupling dynamic equation of the stator system ; The main exciting force of the vibration is electromagnetic force in the stator that is calculated using the Maxwell tensor and the magnetic method in consideration of the radial vibration displacements with the magnetic field in air gap coupling of the stator core; By means of the combination method of beam function, the analytic expressions formula of the radial vibration displacements of sta- tor core is derived. The model conforms to the actual switched reluctance motor structure and opera- tion characteristics. This paper provides theory basis of switched reluctance motor for structure optimization design and prediction and control of electromagnetic vibration and noise. With a model of 8/6 switched reluctance motor as an example, this paper verify the correctness of the analytical models comparing its results with the one obtained using the finite element method.
