ABSTRACT:
A stator for an electric machine includes a generally cylindrically-shaped stator core having a plurality of core teeth that define a plurality of core slots, the core slots extend between first and second ends of the stator core. A stator winding has a plurality of phases, N, each phase including at least one conductor having a plurality of slot segments housed in the core slots, the slot segments are alternately connected at the first and second ends by a plurality of end loop segments. At least one conductor has a slot segment that is switched with an adjacent conductor such that the conductor has an end loop segment having a pitch equal to N+1 and the end loop segment of the adjacent conductor has a pitch equal to N−1, wherein the end loop segments of the conductor and the adjacent conductor do not cross one another. The stator also reduces overall noise of an electric machine.
