Stator winding having transitions

摘要

A stator for an electric machine includes a generally cylindrically-shaped stator core having a plurality of circumferentially spaced core slots. A stator winding includes a plurality of phases, each including at least a first filar and a second filar extending circumferentially around the stator core to form a plurality of layers. Each of the filars is a conductor having a plurality of slot segments disposed in the core slots. The slot segments are alternately connected at the first and second ends of the stator core by a plurality of end loop segments that may form a cascaded winding pattern. The plurality of filars of each phase alternating radial positions with one another within at least one end loop segment at discreet locations around the stator core such that the average radial position of the slot segments of the first filar conductors is substantially equal to that of the second filar.
