Title
(ZH) 一种结构改良的电机定子
Abstract
(ZH)

本实用新型公开了一种结构改良的电机定子,其包括定子齿,相邻的两个定子齿的齿根之间桥接拱桥部;该结构改良的电机定子通过两种方式来避免磁场干扰,其一,各拱桥部具有一个沿着多边形依次连接的至少两条侧边延伸而成或者沿着椭圆形侧边延伸而成或者呈“M”形状的拱圈;其二,各定子齿的齿根位置设置放大区端口,各拱桥部分别介于相邻的两个定子齿的齿根之间,且位于相应的放大区端口范围外。上述两种结构形式的电机定子分别通过扩大定子槽底部所设的拱桥部的两端空间的方式以增加磁场通过的空间,进而避免产生干扰;同时,上述两种结构形式的电机定子能够维持通过拱桥部切割相邻磁场所能获得的功效,还具有避免干扰的优化效果。
