    摘要： 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 thereto at the second coil-end group to form a lap winding. The wave winding and the lap winding are connected in series by the connection segments to form one of the plurality of phase-windings.

    摘要： The present invention provides a compact, efficient and noiseless alternator for an automotive vehicle which employs a double-layer coil arrangement in a slot for eliminating coil end interference as well as improving the space factor. An automotive alternator comprises a Lundel-type core rotor with 16 poles, and a stator with toothed portions of 96 poles spaced by slots. U-shaped conductor segments are installed in the slots. One portion of the conductor is accommodated in an outer layer portion of a predetermined slot, while the other portion is accommodated in an inner layer portion of a slot phase shifted by an electric angle of 180°. In this manner, all of the slots are separated into the inner and outer layers to accommodate a plurality of conductor segments. These conductor segments are connected only at one side of the stator to form a total of twelve wavy winding coils. These twelve wavy winding coils are divided into three groups each consisting of a serial connection of four wavy windings to constitute one phase of a three-phase stator coil.
