The invention discloses a stator, a motor, an electric power steering system and a vehicle, the stator comprises an annular busbar and a stator insulation frame, and the lower end of the busbar is provided with a buckle extending downwards; the stator insulation frame is located below the busbar and is clamped and fixed with the busbar, the stator insulation frame comprises a plurality of frame units which are annularly arranged, each frame unit comprises an outer frame plate, an inner frame plate and a winding part, an outer contour is defined by the plurality of outer frame plates, and an inner contour is defined by the plurality of inner frame plates; wherein the outer contour surface of the outer frame plate and the inner contour surface of the inner frame plate are concentric arc surfaces, a buckling groove matched with the buckle is formed in the outer contour surface, a guide groove is further formed in the outer contour surface, and the guide groove is located above the buckling groove. According to the stator provided by the invention, the guide groove located above the buckling groove is formed in the outer contour surface, and the guide groove can provide a guide effect for the process that the buckle moves towards the buckling groove and is clamped, so that the buckle is convenient to align with the buckling groove.
本发明公开了一种定子、电机、电动助力转向系统及车辆,其中,定子包括呈环形的汇流排和定子绝缘框架,汇流排的下端设置有向下伸出的卡扣;定子绝缘框架位于汇流排下方并与汇流排卡接固定,定子绝缘框架包括呈环形排列的多个框架单元,每个框架单元均包括外框板、内框板以及绕线部,多个外框板围合成外轮廓,多个内框板围合成内轮廓;其中,外框板的外轮廓面和内框板的内轮廓面为同心的圆弧面,外轮廓面上设置有与卡扣配合的扣合槽,并且外轮廓面上还设置有导向槽,导向槽位于扣合槽的上方。根据本发明的定子,外轮廓面上设置有位于扣合槽的上方的导向槽,导向槽能为卡扣向扣合槽移动并卡接的过程提供导向作用,从而方便卡扣与扣合槽的对齐。
