Patent ID: 7170211

Claim:
A stator for an electric machine, comprising: a generally cylindrically-shaped stator core having a plurality of circumferentially spaced and axially-extending core slots in a surface thereof, said core slots extending between a first and a second end of said stator core; a stator winding having a plurality of phases, each phase comprising at least a first filar and a second filar extending circumferentially around said stator core to form a plurality of layers; each of said filars being a conductor having a plurality of slot segments disposed in said core slots, said slot segments alternately connected at said first and second ends of said stator core by a plurality of end loop segments, said first filar having a first set of a plurality of consecutive slot segments having at least a first and second consecutive slot segment wherein each slot segment is disposed at substantially the same radial distance from a central axis of said stator core and having a second set of a plurality of consecutive slot segments having at least a third and fourth consecutive slot segment wherein each slot segment is disposed at substantially the same radial distance from a central axis of said stator core; said plurality of consecutive slot segments of said first set being disposed at substantially the same radial distance from a central axis of said stator core as said plurality of consecutive slot segments of said second set; and said slot segments of said first and second filars of a particular phase alternating radial positions with one another within at least one discreet location around said stator core.
