The invention provides a stator assembly, a wheel hub motor with the stator assembly and an electric vehicle, the stator assembly comprises a stator assembly, a winding and a limiting frame, the stator assembly comprises a tooth part without a tooth boot and a yoke part which has a certain thickness and is closed, and the tooth part is distributed on the periphery of the yoke part; the winding is arranged on the tooth part; the limiting frame is connected with the stator assembly, and the limiting frame is used for limiting the radial position of the winding relative to the tooth part. According to the stator assembly provided by the embodiment of the invention, the material utilization rate of the silicon steel sheets can be improved by arranging the tooth parts without the tooth boots, and meanwhile, the tooth parts without the tooth boots are favorable for winding a winding on an external tool, and then the winding is radially inserted into the tooth parts; due to the lack of tooth boots for positioning the windings, the windings have the risk of sliding out of the tooth parts, the limiting frames can effectively prevent the windings from sliding out of the tooth parts, and stable and reliable product performance is guaranteed.
本发明提供一种定子总成及具有该定子总成的轮毂电机、电动车,定子总成包括定子组件、绕组及限位架,所述定子组件包括无齿靴的齿部及具有一定厚度且形成封闭的轭部,所述齿部分布在所述轭部的外周;绕组设置于所述齿部;限位架与所述定子组件连接,限位架用于限制所述绕组相对所述齿部的径向位置。本实施例的定子总成通过设置无齿靴的齿部可以提高硅钢片的材料利用率,与此同时,无齿靴的齿部有利于绕组在外部工装上完成绕线,然后再径向插入到齿部;由于缺少齿靴对绕组定位,绕组存在从齿部滑出的风险,而限位架可以有效的避免绕组从齿部滑脱,保证产品性能稳定可靠。
