Abstract
In an alternator for a vehicle having a field coil for generating rotating magnetic field and stator coils for generating alternating current voltages in response to the rotating magnetic field, the stator coils are grouped and wound in a dual winding system. In order to reduce magnetic noise, a first group of coils are provided in contact with a stator core and the second group coils. The first and second group of coils are shifted from each other by .pi./3 radian in electrical angle.
