PURPOSE: To obtain an AC generator for a vehicle, capable of reducing an electromagnetic sound of 12f components of higher harmonic sound which is very displeasing to auditory organs and the sound of wind, reducing uncomfortable noise, also low suppressing a decrease of an output by a phase difference. CONSTITUTION: In this AC generator, having a number of slots 61a of 2 per phase and one pole, a space between center lines A extended in a diametric direction of opening parts O1, O2 of each adjacent slot 61a is unevenly formed, first/second three-phase stator windings are wound to a stator core 61 with a phase difference of electrical angle 31 to 34deg..
