进一步地，多个第一冲片100叠设出定子铁芯10的主体段，第一冲片100包括第一定子槽1004；第二冲片200沿定子铁芯10的轴向，第二冲片200叠设于主体段的两端。
在该实施例中，如图4所示，定子铁芯10由多个冲片沿着轴向连续层叠构成。其中，定子铁芯10包括至少两种冲片。沿定子铁芯10的轴向，定子铁芯10中间部分为主体段，由多个第一冲片100连续堆叠形成，第一冲片100包括沿周向分布的多个第一定子齿1002；定子铁芯10的两端部分由多个第二冲片200叠加在一起形成，也即第二冲片200叠设于主体段的两端。其中，第一冲片100的结构与第二冲片200的结构不同。通过采用两种结构的第一冲片100和第二冲片200，通过第一冲片100保证电机1的整体性能，通过在端部设置第二冲片200，使得第二冲片200与第一绝缘骨架20和第二绝缘骨架30进行安装配合，进而进一步地在定子铁芯10的轴向上减小电机1的轴向尺寸，有利于电机1小型化设计。
进一步地，多个第一冲片100构成了定子铁芯10的主体段，位于主体段两端的第二冲片200的数量可以分别为一个或多个，示例性地设置数量，可以根据具体的电机1设置参数进行设定，在此不再赘述。

可以理解的是，第二绝缘骨架30与第一绝缘骨架20互相对应，因此，在第一绝缘骨架20的过线槽206上设置有限位槽，那么在第二绝缘骨架30也具有限位槽，其中，限位槽在沿内侧壁302到外侧壁304之间的底板306上均匀分布。

可以理解的是，电机1的引出导线口靠近于引线槽，因此，第一绝缘骨架20靠近电机1的引出线一侧，那么相对的第二绝缘骨架30远离电机1的引出线一侧。
进一步地，绕组40绕设于第一绝缘骨架20的绕线匝数与绕组40绕设于第二绝缘骨架30的绕线匝数相同。

进一步地，通过对第二侧壁204的高度作出合理限定高度后，再利用第二侧壁204的高度对第一侧壁202的高度进行限定，以实现对整个第一绝缘骨架20的高度进行限定，进而实现了电机1设计的合理化，即满足对绕组40的限位作用，又能够最大限度地降低第一绝缘骨架20的高度，从而有效降低电机1体积，有利于电机1小型化。
