Abstract:
An a.c. generator for a vehicle, comprising:a rotor rotatably supported within a case; and a stator comprising a cylindrical stator core in which a plurality of slots are formed at given intervals circumferentially so as to open toward the inner peripheral side thereof and a stator winding constructed by connecting three single-phase windings wound on said stator core into a Y connection, said stator being fitted onto said case so as to surround said rotor, wherein each of said single-phase windings comprises a first winding which is connected into the Y connection and a second winding which is connected in series to said first winding and has a given phase difference in electrical angle with respect to said first winding, and wherein a connecting portion of said first winding and said second winding constituting each of said single-phase windings is connected to a pair of three-phase diode bridges, and an end portion of said second winding of each of said single-phase windings is connected to another pair of three-phase diode bridges.
