Abstract:
1. A method of forming a stator core assembly for an electric machine of the type having a rotor assembly and a stator assembly, the stator assembly of the type having an annular core defining an outside diameter, an inside diameter, and a plurality of radially projecting winding slots opening to the inside diameter but terminating short of the outside diameter, the core further defining a lead side and an opposite non-lead side, the method comprising the steps of: a) providing two electrical conductors designated as conductor A and conductor B, b) winding the conductors into the winding slots where: c) the winding including placing a first lead of conductor A into the slot number d) the winding including placing a first lead of the conductor B into slot number n+1 with the conductor B first lead extending from the stator lead side end, e) the winding including shifting the conductor A to the slot number n+1 thereby forming an end loop on the non-lead side end and lying in the slot number n+1 radially shifted inwardly from the conductor B and located in the second outermost radial portion of the slot, f) the winding including shifting the conductor A to the slot number g) the winding including shifting the conductor B to the slot number h) the winding including shifting the conductor B to the slot number i) repeating winding steps e) through h) for every n+1 slot, through slot number m+1−n for conductor A, and slot number j) the winding including shifting the conductor A from slot M+1−n radially inward into the third outermost portion of slot number k) repeating steps e) through j), thereby forming additional layers through L wherein the conductors A and B of each layer K will lie in
