Patent ID: 6940201

Claim:
A rotary electric machine, comprising: a rectifier device for rectifying voltages induced in the multi-phase winding; a stator core having a plurality of slots; and a multi-phase winding including a plurality of phase windings wound in the slots at predetermined angular intervals, wherein: one end of one of the phase windings is connected to a middle point other than both ends of another one of the phase windings in a cyclic manner among the phase windings; the multi-phase winding has a plurality of separate electric conductor segments connected in series; each of the slots receives therein generally a same number of the conductor segments; the electric conductor segments are connected together through respective end portions; each of the phase windings includes a first winding and a second winding connected in series, the first winding being connected to the middle point of the another one of the first phase windings and having a middle point to which a third one of the first phase windings is connected, and the second winding being connected to the rectifier device and the second winding having no middle point which is connected to the another one and the third one of the phase windings, and only a part of the first winding of each of the phase windings provides a Δ-connection of a stator winding of an alternator, and the second winding of each of the phase windings is connected to the rectifier device to provide a Y-connection of the stator winding of the alternator.
