Patent ID: 7696659

Claim:
An alternator comprising: a rotor with a field wiring receiving a field current; a stator with a multi-phase stator wiring, an alternating current being generated in the stator wiring in response to a rotation of the rotor and the field current received in the field wiring; a single rectifier that converts the alternating current of the stator wiring into a direct current and outputs the direct current as an electrical energy generated in the alternator; and a single regulator that regulates the field current to control the electrical energy, wherein the regulator and the rectifier are disposed away from each other with the rotor between, and wherein the rotor receives a rotational force on a driving side thereof, the rectifier is disposed only on the driving side of the rotor, and the regulator is disposed only on an anti-driving side of the rotor opposite to the driving side.
