摘要
本文提出用向量位分析增强型混合式步进电动机齿层磁场的边值问题,并介绍用有限元法求解时边界条件的处理方法,分析的步进电动机齿层区域包括:气隙、定转子齿层部分铁心和定子槽中水磁体。文中对不同情况下的齿层磁场分别进行了计算并作出其磁场分布图,可以形象地说明增强型混合式步进电动机齿层区域磁场的变化:还与标量位分析模型作了比较.证明两种方法的等效性。
A Vector potential analysis model for the boundary value problem of the tooth layer magenetic field in enhanced hybrid stepping motors is presented. The consid- ered region of the tooth layer includes: airgap, permanent magliet embedded in the stator slot and saturated iron core. A treatment method of the boundary condi- tion is introduced whcn a finite element method is used. The tooth layer magne- tic fields in various cases are calculated and flux lines are plotted. it is helpful to recognize the difference between the tooth layer magnetic fields in enhanced hybrid stepping motors and standard stepping motors, Also, comparison of the vector potential model with scalar potential model is given. They are proved to be equ- ivalent
