Abstract
In one aspect, a stator is provided having a first cylindrical surface with a plurality circumferentially spaced winding slots, each winding slot extending along an axial length of the first cylindrical surface and formed to embed a segment of a single stator winding, Each stator winding is preformed as a closed loop and two substantially parallel segments of each stator winding formed to be embedded in a first and a second winding slot of the stator, with the second winding slot being the third adjacent winding slot to the first winding slot. Each of the three stator windings has a first winding head segment leaving the winding slots in axial direction of the stator, the first winding head segment of a first winding of the three stator windings describing in space in parts a combination of a rotation about an axis and a translation along that axis.
