Abstract
In the alternating current generator for vehicle, an armature coil comprises a Y-connected first three-phase armature coil and a delta-connected second three-phase armature coil whose phase windings are inserted into same slots respectively. Each of the three-phase armature windings is provided with rectifying means for converting respective a.c. output into a direct current. The direct currents are summed to provide an output of the generator. It is effective to use a plurality of rotary magnet poles provided on a shaft of the generator for a compact a.c. generator in which the radial dimension of the rotary magnet poles is reduced.
