Stator winding having radial aligned wraps

摘要

An electric machine stator having end loop segments includes a multi-phase stator winding having a plurality of radially aligned partial wraps, wraps, and wrap sets, that are adapted to be placed in a plurality of circumferentially spaced axially-extending core slots in a surface of a stator core. The stator winding includes a plurality of slot segments alternately connected at the first and second ends of the stator core by a plurality of end loop segments to form the winding. The end loop segments include first and second sloped portions meeting at an apex portion. Each of the end loop segments includes a radial outward adjustment and a radial inward adjustment and forms a cascaded winding pattern.
