Abstract:
A multiple phase winding for use in electromotive devices using an axial gap structure, comprising:a plurality of individual windings, each of said individual windings corresponding to a single phase and having a first face directed in a first axial direction and a second face directed in the opposite axial direction; each of said individual windings also defining a plurality of working length portions, and a plurality of interior and exterior end turn portions; wherein the first face of one of said individual windings crosses over the second face of another of said individual windings in the area of at least one of their respective interior and exterior end turn portions, defining a crossover area, and wherein the crossover areas of the first and second faces of said respective individual windings define intermeshing notches, resulting in said multiple phase winding having at least one end turn region with at least a portion of the first face of that one end turn region lying in a first plane and comprising portions of all of the first faces of all of the respective end turn portions of all of said individual windings, and at least a portion of the second face of that one end turn region lying in a second plane and comprising portions of all of the second faces of all of the respective end turn portions of all of said individual windings.
