To reduce electromagnetic noise and wind noise of an alternator, it is proposed that the number of slots in a stator is set to one per set, per phase, per pole, and to dispose stator windings such that two sets of three-phase coils have a phase difference from each other, and center-to-center intervals of circumferential gaps of adjoining slot openings are non-uniform. In particular, it is proposed that circumferential width of flanges at distal ends of teeth are set such that the flanges at both distal ends of the teeth (65a, 65b) installed between adjoining claw-shaped magnetic poles overlap proximal ends of claw-shaped magnetic poles (22, 23) as observed from a radial direction. <IMAGE>
