摘　　要：低速永磁直线同步电机(LPMLSM)是利用齿槽效应引起的气隙磁导变化原理工作的,根据LPMLSM的基本结构和工作原理用解析法分析了永磁体和电枢绕组单独作用时的气隙磁场,并将电机模型进行等效,得出了合理二维场磁密分布,结果表明与理论分析一致。The principle of low speed permanent magnetic synchronous linear motor（LPMLSM） is based on the air-gap permeance caused by the slot effect. According to the basic structure and working principle of LPMLSM. Analysis method is adopted to analyze the permanent magnet and armature winding that act on the air-gap field alone ,equivalent model is obtained to analyze the distribution of the magnetic field, obtaining the air-gap field of LPMLSM, the result is in accord with the theory.
