摘要

提出了一种计算单极四相混合式步进电机定子表面振动的简单模型。利用磁导率模型及其等效磁路计算了每极的近似径向磁力。根据计算的径向磁力和定子迁移率的测量值，估计了定子极顶的径向振动谱。计算结果与实测结果吻合较好。由于电动机的特殊结构和激励，这种分析方法与一般用于感应电机振动研究的方法有很大的不同。

A simple model to calculate the stator radial vibration of a hybrid stepping motor

A simple model for calculating the stator surface vibration of a unipolar four-phase hybrid stepping motor is presented. The approximate radial magnetic force per pole is calculated using a permeance model and its equivalent magnetic circuit. Based on the calculated radial magnetic forces and the measured stator mobility values, the radial vibration spectrum on top of a stator pole is estimated. The results show a reasonable agreement between the calculated and measured radial vibration levels. This verifies the analytical approach which, due to the special structure and excitation of the motor, is significantly different from the technique commonly employed for vibration study of induction machines.<>
