根据本申请实施例的定子，在上伸出部122的外周壁上设置多个接线端子16卡槽，多个接线端子16插接在多个端子卡槽1221内，接线端子16安装方便，同时，端子卡槽1221能够对接线端子16的位置进行固定，加强了接线端子16与绕组14之间连接的稳定性，防止接线端子16发生变形同时能够使接线端子16与绕组14连接稳固。而且，通过在上伸出部122设置不同深度的缺口1222以及不同高度的凸起层，连接线15、绕组14的起始端1401和结束端1402可以方便地引出而沿上伸出部122的周向排布在不同高度的走线空间内，避免了连接线15在绕线时避免重叠和交叉，因此，绕组14的匝数可以更多，布线工艺和结构简单，不相互干涉，提高了电机性能。
根据本申请实施例提出的定子1还包括端子支撑座17，多个接线端子15安装在端子支撑座17上，接线端子16的下端从端子支撑座17伸出以插接在端子卡槽1221内，通过端子卡槽1221与端子支撑座17的配合，增强了接线端子16与绕组14连接的稳定性的同时，使接线端子16保持其位置度和挠度。
在一些实施例中，如图2和图3所示，端子卡槽1221的外侧设有用于钩挂起始端1401和结束端1402的端子挂钩12224，端子挂钩12224用于对绕组14的连接线15进行固定并使绕组14通过端子挂钩12224与接线端子15连接。

通过设置三个不同深度的第一缺口12221、第二缺口12222和第三缺口12223，能够使绕组14的起始端1401和结束端1402从第一缺口12221、第二缺口12222和第三缺口12223引出时，在上伸出部122的外周壁上能够自然形成不同高度的绕线路线，避免连接线15在绕线过程中重叠和交叉。
通过在上伸出部122设置不同深度的缺口1222以及不同高度的凸起1223，在上伸出部122的外侧周向形成不同高度的走线空间，绕组14的连接线15、起始端1401和结束端1402 可以方便地引出而沿上伸出部122的周向排布在不同高度的走线空间内，避免了重叠和交叉，因此，绕组14的匝数可以更多，布线工艺和结构简单，不相互干涉，提高了电机性能。

在一些实施例中，第一凸起12231临近上伸出部122的上沿，第二凸起12232临近第一缺口12221的底壁，第三凸起12233临近第二缺口12222的底壁，第四凸起12234在上绝缘框架12的轴向上临近第三缺口12223的底壁，当绕组14的连接线15从各个缺口1222引出上绝缘框架12并进入走线空间中时，第一凸起12231、第二凸起12232、第三凸起12233和第四凸起12234能够相互配合将各个绕组14的连接线15限制在走线空间的各层中并防止各层连接线15交叉重叠。
在一些实施例中，第三凸起12233与第四凸起12234在上绝缘框架12的轴向上的距离大于第一凸起12231与第二凸起12232、第二凸起12232与第三凸起12233在上绝缘框架12的轴向上的距离，当两组连接线15与同一相接线端子16连接时，能够使与同一相接线端子16连接的两组连接线15同时位于第三层走线空间中并且由于第三层走线空间大于第一层走线空间和第二层走线空间，能够使处于第三层走线空间中两组连接线15相互分离，在一些实施例中，第三层走线空间中还能够增加一个凸起，以使位于第三层走线空间中的连接线15相互分离。
在一些实施例中，第四凸起12234在上绝缘框架12的周向上的长度大于第一凸起12231、第二凸起12232和第三凸起12233中的任一个在上绝缘框架12的周向上的长度。
