MAGNET-TYPE ROTATING ELECTRIC MACHINE

摘要

There is provided an alternating current generator for a vehicle, including: a rotor (1), a flywheel (3), and main magnets (4) and auxiliary magnets (5) alternately arranged; and a stator (2). Each of the main magnets (4) is magnetized to an N-pole and an S-pole in a radial direction, whereas the main magnets (4) are arranged so that the main magnets (4) adjacent to each other through corresponding one of the auxiliary magnets (5) therebetween are magnetized to have opposite polarity patterns. Each of the auxiliary magnets (5) is magnetized to the N-pole and the S-pole in the circumferential direction, whereas the auxiliary magnets (5) are arranged so that the auxiliary magnets (5) adjacent to each other through corresponding one of the main magnets (4) therebetween are magnetized to have opposite polarity patterns.
