摘　　要：从分数槽绕组的基本概念出发,简述了分数槽绕组的基本特征和对称条件,介绍了它在永磁无刷电动机和永磁交流伺服电动机中的应用;重点对中小型永磁无刷电动机中广泛使用的y=1的分数槽绕组进行分析,给出了常用的槽极配合和绕组设计计算参数,阐明了分数槽绕组对齿谐波电势和齿槽转矩削弱的规律。According to the concepts of fractional-slot winding, the basic characteristics and symmetry Condition is given. Applications of fractional-slot winding in PM brushless motor and PM AC servo motor have been presented. The fractional-slot winding of y = 1 widely used in middle and small PM brushless motor is analyzed, and slot concert and winding design calculate parameter is given. Some laws of slot harmonic electromotive force and reduciug cogging torque of fractional-slot winding is proposed.
