Abstract
An ac generator for a vehicle includes a rotor having a field coil, a stator having a stator winding disposed around the rotor to provide ac power in cooperation with the rotor, a brush unit disposed near a rotation axis of the rotor, and a voltage regulator for controlling output voltage of the ac power. The voltage regulator has a regulator circuit section and a heat sink for dissipating heat generated by the regulator circuit section. The heat sink has a plurality of axially projecting cooling fins that extends in a circumferential direction of the rotor.
