    Abstract: An electric machine stator having end loop segments includes a multi-phase stator winding having a plurality of radially aligned partial wraps, wraps, and wrap sets, that are adapted to be placed in a plurality of circumferentially spaced axially-extending core slots in a surface of a stator core. The stator winding includes a plurality of slot segments alternately connected at the first and second ends of the stator core by a plurality of end loop segments to form the winding. The end loop segments include first and second sloped portions meeting at an apex portion. Each of the end loop segments includes a radial outward adjustment and a radial inward adjustment and forms a cascaded winding pattern.

    Abstract: A stator core assembly for an electric machine of the type having a rotor assembly and a stator assembly 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 the inside diameter but terminating short of the outside diameter. The stator core further comprising a plurality of layers, N, each layer including a first continuous electrical conductor designated as A conductor and a second continuous electrical conductor designated as B conductor, thereby including two electrical conductors per layer and an even number of electrical conductors in total. A plurality of electrical connections in between and interconnecting the conductors includes at least one parallel connection and one series connection, such that the plurality of connections define an odd number of electrical turns.

    Abstract: A stator core assembly having an annular core defining an outside diameter, an inside diameter, and a plurality of radially projecting winding slots. A first electrical conductor and a second continuous electrical conductor are inserted within the winding slots circumferentially around the stator core. The conductors form a plurality of layers, each layer being defined as one substantially complete circumferential pass of the conductors around the stator core. Each of the conductors include a plurality of straight portions that lay within the winding slots, and a plurality of end loop portions that extend circumferentially to connect two of the straight portions. The length of the straight portions and end loop portions vary between the layers based upon the radial location of the particular layer within the stator core and a pre-determined axial height of the end loop portions.
