摘　　要：介绍了凸极同步电机磁极的结构型式及其固定方法,并对固定磁极用螺栓的受力进行了分析,避免了常规思路下预紧力与离心力叠加的所导致的螺栓材质及型号的错误选择问题,为后续电机的设计提供了参考。This paper introduces the structure type and fixing method of salient pole synchronous motor, and analyzes the stress of the fixing bolt of magnetic poles. It avoides the wrong selection of bolt material and type caused by the superposition of pretightening force and centrifugal force in the conventional way, and provides a reference for the subsequent motor design.
