铝漆包线在单相交流永磁同步电机上的应用

Application of Aluminum Enameled Wire into the AC Single-phase PM Synchronous Motor

U形铁心永磁同步电机定子绕组由两个集中绕组串联连接,原采用环形绕线工艺,使用铜漆包线,线径在0.21 mm^0.40 mm之间。现将铜漆包线绕组改为铝漆包线绕组,经实践技术可行,成本优势明显。文章从铝漆包线电磁方案调整、绕组绕制、铝漆包线褪漆膜、铝漆包线焊接和焊点防腐蚀等方面作了详细介绍。

Stator windings of the PM synchronous motor with U-shaped core were connected by two concentrated winding in series. Usually, the copper enameled wire was employed within the diameter from 0.21mm to 0.40mm while circular winding process was conducted. The technology of applying aluminum wire to replace the original copper wire was proved feasible in the practice of the production of this motor, thus, the cost advantages became very obvious. The technical solutions were introduced in detail in the fields of electromagnetic program adjustments, aluminum wire winding, aluminum wire faded paint, aluminum wire welding, corrosion protection and etc.
