如图5所示，为定子绕组2的每相第二路绕线22的绕线方式，2f具有第二引出线5，8e具有第二星点线6，定子绕组2的每相第二路绕线22的绕线起点为2f处，定子绕组2的每相第一路绕线21的绕线具体方式为：
2f->43f->1e->43d->1c->43b->1a->43a->37b->43c->37d->43e->37f->32f->38e->32d->38c->32b->38a->32a->26b->32c->26d->32e->26f->19f->25e->19d->25c->19b->25a->19a->13b->19c->13d->19e->13f->8f->14e->8d->14c->8b->14a->8a->2b->8c->2 d->8e。
通过此绕线方式进行绕线，可以优化定子绕组2的每相第二路绕线22的绕线结构，此种绕线方式能够使第二引出线5与第二星点线6均布置在焊接端232，可以充分利用焊接端232的高度。
并且，该定子绕组2路数容易调整，将定子绕组2的每相第一路绕线21的第一星点线4与定子绕组2的每相第二路绕线22的第二引出线5进行扭头焊接，即可由两路绕线变一路绕线，在路数调整时，不容易产生不平衡的电流，可以防止产生环流现象，从而可以防止电机失效。
另外，在绕线过程中，通过将多个跨跃段设置与其他跨越段不同的节距，将定子槽11的电位矢量平衡，抑制槽矩角的电位相角差，最终实现子路之间电位的均衡，可以抑制定子绕组2内部环流，有低温升效果，并且，在抑制环流的同时，也可抑制环流产生的谐波电磁激励，从而可以大幅度地抑制电机工作时的振动和噪声。
由此，通过定子铁芯1和定子绕组2配合，能够使第一引出线3与第一星点线4均布置在焊接端232，可以充分利用焊接端232的高度，也能够防止产生环流现象，可以防止电机失效。
在一些实施例中，如图2和图5所示，n＝i，需要解释的是，图2中第i槽可以为第1槽，图5中第n槽为第1槽，如此设置能够使每相第一路绕线21与每相第二路绕线22的设置更加合理，可以使定子绕组2的绕线结构得到优化，从而可以提升定子绕组2的工作性能。
在一些实施例中，如图10-图14所示，定子绕组2可以包括多个导体段，每个导体段可以包括弯折部231和分别连接至弯折部231的第一槽内部分233和第二槽内部分234,在焊接端232上多个导体段的位于相邻层的第一槽内部分233和第二槽内部分234焊接连接。第一槽内部分233穿过其中一个定子槽11中的其中一个槽层12，第二槽内部分234穿过另一个定子槽11中的其中一个槽层12，第一槽内部分233和第二槽内部分234穿过定子槽11后其端部超出定子铁芯1。
其中，第一槽内部分233的远离弯折部231的端部位于定子槽11外部，该部分结构可以构造出一焊接端232，相应地，第二槽内部分234的远离弯折部231的端部位于定子槽11外部，该部分结构可以构造出另一焊接端232。
导体段的垂直于其延伸方向的任一横截面为非圆形，作为一个实施例，横截面均为矩形形状。可选地，U形导体段的任一横截面为长方形形状，长方形的短边垂直于定子槽11底壁。更进一步地，在U形导体段的延伸方向上，U形导体段的横截面面积相等。当多个导体段同时插入到定子铁芯1的定子槽11内之后，相邻的导体段之间的防干涉 效果更好。

在一些实施例中，第二类导体段24位于第二跨跃段2112、第三跨跃段2113、第五跨跃段2115、第六跨跃段2116、第八跨跃段2122、第九跨跃段2123、第十一跨跃段2125、第十二跨跃段2126、第十四跨跃段2212、第十五跨跃段2213、第十七跨跃段2215、第十八跨跃段2216、第二十跨跃段2222、第二十一跨跃段2223、第二十三跨跃段2225和第二十四跨跃段2226。
