Abstract
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 a plurality of filars, each filar extending circumferentially around the stator core to form a plurality of layers. Each of the filars is a conductor having a plurality of substantially straight segments disposed in the core slots. The straight segments are alternately connected at the first and second ends of the stator core by a plurality of end loop segments. The filars of a particular phase each have an average radial position within the stator core, and are staggered throughout the layers such that a distance between the average radial position of each filar and the average radial position of the other filars is minimized.
