技术领域
本申请涉及电机技术领域，具体而言，涉及一种定子组件及包括该定子组件的电机。
背景技术
目前，在现有技术中对电机进行绕线处理时，由于绕线的绕线槽大小较为固定，从而使定子铁芯的功率等级受限，每次绕线前，均已经设定好对应的运行功率，极大影响产品的拓展，同时由于绕线方式较为单一，也影响绕线效率。
发明内容
为了解决上述技术问题至少之一，本申请的一个目的在于提供一种定子组件。
本申请的另一个目的在于提供一种包括上述定子组件的电机。
为了实现上述目的，本申请第一方面的技术方案提供了一种定子组件，包括：定子铁芯，所述定子铁芯包括：定子轭部；以及至少一个定子齿，每个所述定子齿沿所述定子轭部的轴向设置，且所述定子齿与所述定子轭部可拆卸连接；至少一个绕组，绕设于至少一个所述定子齿上，其中，所述定子轭部设有与所述定子齿的形状相适配的定子轭槽和/或定子凸台，所述定子齿穿过所述定子轭槽和/或所述定子凸台形成所述定子铁芯。

值得说明的是，定子齿身和定子齿靴的材质可以相同，也可以不同。
实施例四
