  • the per-coil coil winding of the motor is formed by winding a winding of the original long span into two or more short-span windings.
  • the coil windings can be used in parallel, in series, or in series according to their homopolarity.
  • the new type of winding is designed as two or more short-span windings in the original one-phase per-pole coil winding.
  • the preferred winding made by this timing method has the following advantages:
  • phase invention Because the coil winding adopts the short span preferred winding method, it is much shorter than the original span. The size reduces the ineffective side of the winding. When the total number of turns per pole is constant, the copper wire is saved (the wire can be saved by 5%-15%), the copper consumption is reduced, and the efficiency is improved.

本申请要求于 2009 年 2 月 27 日提交中国专利局、 申请号为 200920136860.2、 发明名称为"电动机改进式绕组"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及一种电动机绕组的改进技术，特别是一种节材、 高效的电动机 改进式绕组， 亦称电动机优选绕组。 背景技术 随着科技的发展， 电动机的型号规格越来越多， 其线圈绕组也各有不同。 目前， 电动机生产厂家几乎是按照国际标准或者行业标准讲行绕组的生产， 以 现有三相 24槽 4极异步电动机为例， 其中一相每极线圈绕组 a是由线圈绕制 成一个跨距的绕组构成， 如图 1布置为 1-6, 7-12, 13-18 , 19-24, 这样， 存在 的缺点为： 一是线圈绕组跨距大， 无效边长， 从而造成了铜材的浪费； 二是工 作时线阻的增加， 致使铜损和电损耗加大， 使得电动机的使用寿命短； 三是绕 组利用率低， 用同样的铜材效率无法提高。 发明内容 本发明的目的是要提供一种电动机改进式绕组（亦称电动机优选绕组）， 它采用短跨距优选绕法，使得电动机线圈绕组不仅是具有设计合理， 连接使用 方便的优点， 而且具有节材、 降耗、 高效的显著优点。
本发明是这样构成的， 它包括线圈， 线圈绕制在定子槽内， 定子槽数在
24槽以上， 所述的电动机每极线圈绕组是由线圈将原有一个长跨距的绕组绕 制成二个或多个短跨距的绕组构成。 所述的线圈绕组可根据其同极同性进行并联、 串联、 或者并串联使用。 本使用新型是在原有一相每极线圈绕组是一个长跨距的绕组设计为二个 或多个短跨距的绕组， 这种改时方法制成的优选绕组肯有以下先优点：
1、 相发明由于线圈绕组采用短跨距优选绕制法， 比原有跨距缩短了许多 尺寸， 故减少了绕组的无效边， 在每极绕组总匝数不变的情况下， 也就节省了 铜线（可节省线材 5%-15%左右）， 降低了铜耗， 提高了效率。
2、 由于线阻减少， 故在工作时能够降低铜耗和电损耗， 提高绕组利用率， 从而增加电动机的使用寿命。
