摘　　要：三相不对称分数槽绕组与对称分数槽绕组相比,没有比较系统的排列方法,只有通过研究分析不对称分数槽绕组的排列特点提出每极每相槽数q的分母为3时绕组排列的新方法,并对q分母为6时绕组排列问题进行了简单的分析。另外,针对不对称绕组中通有不对称电流运行时的磁势谐波问题进行了探讨,编制了Matlab通用程序,并利用程序和新的绕组排列方法对定子绕组进行磁势谐波分析并调出有用的结论,为电机的设计、改造以及电机运行磁势谐波分析提供参考。The three-phase asymmetrical fractional-slot windings have no more systematical method of arrangement compared with symmetrical fractional-slot windings.Through research and analysis of asymmetrical fractional-slot winding＇s arrangement characteristics,this paper presents a new method of arranging winding when the denominator of the number of slots per pole per phase q is three and carries out a simple analysis on winding arrangement when the denominator q is six.Furthermore,the problem of magnetic potential harmonic was discussed when the asymmetrical winding has an asymmetrical current and Matlab program was prepared.With the new method and program,this paper analyzes the harmonic magnetic potential of stator windings and gets a useful conclusions.It can provide reference for design and renovation of motor and analysis of harmonic magnetic potential when the motor is running.
