KNURLED MULTIPLE CONDUCTOR WINDINGS

摘要

An example electric machine includes a stator disposed about an axis having a plurality of slots. The electric machine also includes a plurality of windings each having a first portion and a second portion. At least two of the plurality of windings are at least partially disposed within each of the plurality of slots. At least one of the first portion or second portion of at least one of the plurality of windings of each slot includes a first exposed end with a surface having a plurality of grooves, the surface in contact with a second exposed end of at least one other winding of the same slot. The first exposed end and second exposed end form a joint between the plurality of windings. A braze material is dispersed in a plurality of grooves disposed between the first exposed end and the second exposed end.
