ABSTRACT:
A metal film4is disposed between a permanent magnet3and a rotor yoke1, and the permanent magnet3and the rotor yoke1are subjected to beam welding. Since the metal film4is disposed between the permanent magnet3and rotor yoke1, and the metal film4as a laser beam irradiated portion is melted by vacuum beam or laser beam, the metal film4has brazing metal function in welding, so that the connection between the permanent magnet3and the rotor yoke1is strong. Since there is no need of embedding the permanent magnet3in the rotor yoke1and there is no need to use polymer adhesives, the cost can be reduced.
