  • Patent number: 9985486
    Abstract: A method of manufacturing a rotor for a magnet type rotating electrical machine includes the steps of: cutting and laminating pieces of the core of the rotor, to thereby form a core (3); mounting the core (3) on a rotating jig (10); forming a magnet piece (2p) into a predetermined shape by sintering; mounting a predetermined number of the magnet pieces (2p) on a regulating jig (20); pressing the magnet pieces (2p) by the regulating jig (20) while rotating the core (3) by the rotating jig (10), to thereby mount the magnet pieces (2p) on the core (3); and adjusting an axial position of the magnet piece (2p) so that an axial end surface of the core (3) and an axial end surface of the magnet piece (2p) are aligned with each other.
