The embodiment of the invention provides a stator assembly, a motor structure, an electric power steering system and a vehicle, and the stator assembly comprises a stator core which comprises a plurality of stator teeth, and a stator winding is wound on the stator teeth; the insulating frame is arranged at the two ends of the stator teeth in the axial direction of the stator core, and the insulating frame comprises a first baffle arranged on the radial inner side of the stator core; the insulating sheets are arranged on at least one side of the stator winding on each stator tooth along the circumferential direction of the stator core; wherein a first protrusion and a second protrusion are arranged at the two circumferential ends of the first baffle respectively, the radial positions of the first protrusion and the second protrusion are not overlapped, and a circumferential gap exists between the adjacent first protrusion and second protrusion. In the technical scheme of the invention, after a plurality of stator windings are wound on the stator teeth, the insulating sheets placed among the stator windings are blocked by the first bulges and the second bulges in a staggered manner, so that the effect of preventing slipping is realized.

    本发明的实施例提供了一种定子组件、电机结构、电动助力转向系统和车辆,其中,定子组件包括:定子铁芯,定子铁芯包括多个定子齿,定子齿上绕有定子绕组;绝缘架,沿定子铁芯的轴向设于定子齿的两端,绝缘架包括设于定子铁芯的径向内侧的第一挡板;绝缘片,沿定子铁芯的周向设于每个定子齿上定子绕组的至少一侧;其中,第一挡板的周向两端分别设有第一凸起和第二凸起,第一凸起和第二凸起的径向位置不重叠,相邻的第一凸起和第二凸起之间存在周向间隙。本发明的技术方案中,在多个定子绕组在定子齿上完成绕线后,放置在定子绕组之间的绝缘片会被第一凸起和第二凸起交错挡住,从而实现防止滑落的效果。
