AI Technical Summary

Technical Problem

In a 6-layer 8-pole 48-slot flat wire motor, various spans and span differences lead to uneven current distribution, increasing copper loss and circulating current loss. At the same time, the complex structure of the winding ends increases manufacturing costs and defect rate.

Method used

U-shaped hairpins with spans of 5, 6, and 7 are used to evenly distribute the current and simplify the winding end structure. The average span of U-shaped hairpin one, U-shaped hairpin two, and U-shaped hairpin three is 6, which reduces the variety and difference of spans. The welded ends are formed in six layers along the radial direction of the stator core, and the welded ends of U-shaped hairpin three are staggered by five layers to simplify the alternating arrangement.

Benefits of technology

It achieves uniform current distribution, reduces circulating current loss, simplifies the winding end structure, reduces processing costs and production difficulty, and improves motor efficiency and the feasibility of automated production.
