Abstract
In an alternator stator for vehicle, each of the phase-windings includes first and second coil-end groups at opposite axial ends the stator core. Each of the slots includes radially aligned six layers. Each of the phase-windings comprises a plurality of sets of U-shaped segments disposed in a pair of slots separated from each other by a pole-pitch and a plurality of connection segments formed from the U-shaped segments. Each of the sets includes a large segment having a pair of the conductor members disposed in the innermost and the outermost layers, a medium segment having a pair of the conductor members disposed in the layers inside the innermost and the outermost layers to be surrounded by the large segment at the first coil-end group, a small segment having a pair of conductor members respectively disposed in the middle two layers to be surrounded by the medium segment at the first coil-end group. The small segment of one of the sets is connected in series with the small segment of another adjacent thereto at the second coil-end group to form a wave winding. The large segment of one of the sets is connected in series with the medium segment of another of the sets adjacent there…
