Method of forming a stator having skewed slots

Abstract:

A method of inserting a winding into a stator having skewed slots formed on an inside diameter of a stator lamination includes forming a conductor having a plurality of slot segments, loading the conductor into a plurality of skewed slot elements of a linear cartridge having a first end, a second end, and a linear axis connecting the first end and the second end, the plurality of skewed slot elements being angled relative to the linear axis, transferring the conductor from the linear cartridge to a plurality of skewed slot members formed in an outside diameter of a rotary cartridge, inserting the rotary cartridge into the inside diameter of the stator lamination, and shifting the conductor from the rotary cartridge into the skewed slots of the stator.
