An alternator for a vehicle has a pair of Lundell type magnetic poles (9) each provided with a plurality of claw-shaped pole pieces (9b) and permanent magnets (11) each disposed between a space formed by opposed side surfaces of the circumferentially adjacent claw-shaped pole pieces (9b) and magnetized so that the respective polarities of its circumferentially opposite ends are the same as those of the claw-shaped pole pieces. Each permanent magnet is disposed so that the ratio of the length of the permanent magnet (11) to the length of the space formed between the claw-shaped pole pieces (9b) is in the range of 50% to 80%. <IMAGE> |
