摘要：针对永磁电机存在齿槽转矩影响运行性能的问题，通过分析电机齿槽转矩解析表达式的磁极参数，利用有限元软件建立3相4极24槽表贴式永磁同步电机仿真模型，分析永磁体剩磁感应强度、极弧系数以及永磁体厚度的变化对电机齿槽转矩的影响规律，最佳的磁极参数可有效削弱表贴式永磁同步电机齿槽转矩，改善电机运行性能。
关键词：齿槽转矩；剩磁感应强度；极弧系数；永磁体厚度
Abstract: The existence of the cogging torque affect the performance of the permanent magnet motor. By analyzing the magnetic pole parameters of motor cogging torque expressions, a simulation model of surfacemounted permanent magnet synchronous motor with 3 phases 4 poles 24 slots was established by using finite element software, the influence of permanent magnet remanence intensity, pole arc coefficient and permanent magnet thickness changes on cogging torque were analyzed. The optimal magnetic pole parameters can effectively weaken the cogging torque of surfacemounted permanent magnet synchronous motor, improve the motor operating performance.
Key words: cogging torque；remanence intensity；pole arc coefficient；permanent magnet thickness
