An automotive alternator is capable of reducing electromagnetic noises and wind noises of 12f components, which are extremely unpleasant higher harmonic noises to the ears, thereby permitting uncomfortable noises to be reduced, and also capable of suppressing a drop in output caused by a phase difference. In the alternator, two slots are applied per pole in a phase, spaces between centerlines that extend in a radial direction of openings of adjoining slots are formed to be irregular, and a first three-phase stator winding and a second three-phase stator winding are wound around a stator core with a phase difference of an electrical angle ranging from 31 to 34 degrees.
