An auxiliary power motor with improved structure includes wheel shell, rotor ring, stator plate, central wheel axle and control circuit.

一种改良结构的辅助动力马达，包括轮壳、转子环、定子盘、中心轮轴及一控制电路，转子环的内环面埋设磁铁，定子盘周围固设环形矽钢片，其外环面具有多个T形齿牙，其齿数为非转子环磁铁数的公倍数，矽钢片设有三相星形线圈绕组，且于定子盘电机最佳启动角度处设有霍耳元件组；借此将定子盘固设于中心轮轴，令轮壳夹设住转子环并套设于中心轮轴两侧，当转子环旋转时，即可降低磁极间的钝齿转矩，令电动车行进更加顺畅无噪音。
