摘　　要：介绍了一种永磁爪极步进电机 ,由于其特殊的爪极结构 ,磁场分布情况较复杂 ,其理论分析与设计制造都与一般步进电机不同 .本文根据该电机的特殊结构 ,得出其等值磁路图和磁钢工作图 ,并对四相双四拍永磁爪极步进电机的工作原理及其控制系统作了阐述 .在此基础上 ,对该电机的静态转矩与空载起动频率进行了计算 .通过实验结果及数据比较 ,验证了分析方法的正确性 .Presents a claw pole permanent magnet stepping motor.Because of the uniqueness of the claw pole structure and the complexity of the field distribution,it is quite different from traditional motors in theoretical working principle and in design. After the equivalentmagnetic circuit and the working drawing of the magnet steel are obtained from the distinctive structure of the claw pole permanentmagnetstepping motor,the operating principle and control system of this motor are then analyzed.Calculations yielded the static moment and no load starting frequency of the prototype.Clase agreement of calculated results with the experimental results proved the soundness of the method in this paper.
