ABSTRACT:
The first, second and third winding for the stator of a three phase AC machine having n grooves per pole and phase are wound either sequentially or simultaneously. When wound sequentially, the first, second and third winding start at, respectively, a first, second and third groove and end at a first, second and third end groove. The starting grooves are adjacent grooves, that is spaced from each other by a number of grooves equal to n. The same is true for the end grooves. The wires are then interconnected such that the winding start and the winding end of the second winding are electrically interchanged. The winding process takes place in one direction only. When all windings are wound simultaneously, the winding process takes place in a first direction and, upon reaching the end grooves, the winding direction is reversed without creating a winding end at the end grooves. The winding ends are created when the winding in the opposite direction is completed.
