Abstract
A brushless-type alternator has a rotor, which comprises a pair of pole cores. The pole cores include a plurality of nail parts, respectively. The nail parts are arranged alternately in a rotating direction of the rotor. The nail parts are coupled to-each other with a non-magnetic ring. A permanent magnet is interposed between adjacent two of the nail parts, and fixedly held in position with the non-magnetic ring. The permanent magnets are located radially inside or outside the non-magnetic ring.
