Abstract:
An automotive alternator comprising:a stator having: an annular stator core in which slots are disposed at a ratio of two per phase per pole; and a stator winding mounted to said stator core, wherein said stator winding is provided with six winding phase portions each installed in a slot group including every sixth slot of said slots such that each of said slot groups is successively offset by one slot, each pair of said six winding phase portions having a phase difference corresponding to an electrical angle of approximately 30 degrees is connected by an interphase crossover portion, and said interphase crossover portions are arranged so as to be separated in an axial direction from coil ends of said stator winding and so as to be offset in a circumferential direction so as not to overlap each other in a radial direction.
