1. A stator for a dynamoelectric machine, comprising: a generally cylindrically-shaped stator core having a plurality of circumferentially spaced axially-extending core slots in a surface thereof, said core slots extending between a first and a second end of said stator core; and a stator winding including at least one layer of conductors having a plurality of phases, wherein said at least one layer of said phases includes substantially straight segments disposed in a plurality of said core slots that are located at the same radial distance from the central axis of the stator core having end loop portions connecting two straight segments of said phase, wherein said end loop segments form a cascaded winding pattern while keeping said end loop segments substantially radially within their respective layer, and wherein said straight segments have a circumferential width C 1 and said end loop segments have a circumferential width C 2 less than said circumferential width C 1 , and wherein at least one of said phases is radially shifted.
