摘　　要：针对不对称六相分数槽绕组合成磁势的对称性问题,采用槽号相位图法及单元电机理论,对三种典型的不对称六相绕组磁势进行分析。通过与对称三相及六相绕组比较,得出其合成磁势的性质与分数槽绕组每极每相槽数表达式的整数及小数部分取值有关,其变化规律是:在设计允许范围内,整数部分值选取的越大,其特性就越接近对称绕组;当整数部分值一定,小数部分取值越大时,其合成磁势对称性越好。The magnetic motive force（MMF） of the asymmetrical hex winding motor with fraction slots is analyzed in the paper.In order to deal the resultant MMF symmetry problem of the motor which asymmetrical hexa-winding and fraction slots are installed on,the phase diagram and unit motor theory are adopted,and three typical asymmetrical hex-winding MMFs have been analyzed.Through the comparison to the symmetrical three phase windings,the results show that,the characteristics of the MMF are related with the integer and decimal parts of fraction slot numbers per-pole-per-phase.In the allowance,the more of the integer parts are,the better the asymmetrical hexa-windings approach.When the integer parts keep constant,the more of the decimal parts are,the better of the MMF symmetry get.
