An alternator for a vehicle includes a stator (2) having a stator core (32), a stator winding having a first coil-end group (311a) and a second coil-end group (31b) on the opposite ends of the stator core (32), a rectifier (5) disposed near the first coil-end group (31a) and an air drive unit (11, 12) for cooling the first and second coil-end groups (31a, 31b). Because the first coil-end group (31a) has a larger surface to be cooled than the second coil-end group (31b), temperature of both coil end groups (31a, 31b) are controlled to be equal. <IMAGE> |
