1. A stator, comprising: a substantially cylindrical core having two axial ends and a plurality of longitudinally extending slots formed therebetween;a first winding set formed as a continuous first wire disposed about substantially the entire circumference of the core, is disposed in a radial layer of a first slot of the plurality of slots and in two radial layers of a second slot of the plurality of slots adjacent to the first slot;a second winding set formed as a continuous second wire disposed about substantially the entire circumference of the core, is disposed in two other radial layers of the second slot and in a radial layer of a third slot disposed adjacent to the second slot whereby the second slot is disposed between the first and third slots;wherein the first wire is disposed in one additional layer in one of the first and third slots and the second wire is disposed in one additional layer of the other one of the first and third slots whereby the first wire and second wire are disposed in two layers of the first slot, in four layers in the second slot and in two layers of the third slot;wherein the first and second wires define at least one 5-7 pitch end loop section wherein, at a first one of the axial ends of the cylindrical core, the first wire defines a first end loop that exits from the first slot and enters an eighth slot disposed seven slots in a first circumferential direction from the first slot whereby there are six slots disposed between the slots exited and entered by the first end loop and wherein, at the first one of the axial ends, the second wire defines a second end loop that exits from the second slot and enters a seventh slot disposed five slots in the first circumferential direction from the second slot whereby there are four slots disposed between the slots exited and entered by the second end loop;wherein the first and second wires each define 6 pitch end loops on the first one of the axial ends of the cylindrical core on each circumferentially adjacent side of the at least one 5-7 pitch end loop section whereby there are five slots disposed between the slots exited and entered by the first and second wires for each of the 6 pitch end loops; andwherein the two radial layers in which the first wire is disposed in the second slot are radially innermost and radially third innermost, and wherein the two radial layers in which the second wire is disposed in the second slot are radially second innermost and radially fourth innermost.
