Abstract:
A stator core assembly for an automotive alternator of the type having a rotor assembly and a stator assembly, said stator assembly of the type having at least one phase and having an annular core defining an outside diameter, an inside diameter, and a plurality of radially projecting winding slots opening to said inside diameter but terminating short of said outside diameter, said stator core assembly comprising:a first continuous electrical conductor; a plurality of layers, N, each of said layers being defined by one substantially complete circumferential pass of said conductor around said stator core; said conductor including a plurality of straight portions that lay within said predetermined radially projecting winding slots, and a plurality of end loop portions that extend circumferentially to connect two of said straight portions, wherein the length of said end loop portions varies based upon the radial location of said particular layer within said stator core and the end loop axial height varies between radial positions within said stator core based upon the radial location of a particular layer within said stator core.
