AI Technical Summary

Technical Problem

In existing flat wire hairpin winding schemes, the odd number of winding layers leads to high manufacturing and assembly difficulties, which is not conducive to mass production and cost optimization.

Method used

An even-layer winding design is adopted. The first branch is wound from the first layer to the last layer by the pole pitch, and then wound back to the first layer in the opposite direction. This process is repeated back and forth. Combined with flat layer winding, the winding branches are symmetrical. A double-branch design is adopted to simplify the process.

Benefits of technology

It reduces manufacturing difficulty, is suitable for mass production, improves motor efficiency, reduces motor losses and heat, improves temperature rise control, enhances motor reliability and quietness, and reduces manufacturing costs.

Abstract

本申请提供一种电机绕组的绕制方法、定子及电机,该绕制方法中,采用偶数层绕组双支路设计,根据极距将第一支路从第一层绕制到最后一层,再进行一次平层绕制,然后从最后一层反向串线回到第一层,来回重复绕制,当绕制到第一支路的出线端时,第一支路完成绕制,相应地,根据极距将第二支路从最后一层绕制到第一层,再进行一次平层绕制,然后从第一层绕制到最后一层,来回重复绕制,当绕制到第二支路的出线端时,第二支路完成绕制,在绕制过程中,对于单个支路,在绕组出、入线端两侧平层绕制的发卡节距为极距加一得到的值这样,保证绕组支路对称,提升电机的效率。这一链式绕制的绕组结构设计简单,工艺简洁,降低了制造成本,适合批量化生产。
