Abstract
An alternator for a vehicle has a rotor with a field wiring, a stator with a three-phase stator wiring, a regulator, and a rectifier. The regulator and rectifier are disposed away from each other with the rotor between. An alternating current is generated in the stator wiring in response to a rotation of the rotor and a field current received in the field wiring. The rectifier converts the alternating current into a direct current and outputs the direct current as an electrical energy generated in the alternator. The regulator regulates a value of the filed current to control the electrical energy. The rectifier acts as a heat generating member, but heat generated in the rectifier is hardly transmitted to the regulator disposed away from the rectifier.
