A purpose is to provide a rotor manufacturing method including a magnet assembly formed of divided permanent magnet pieces to enhance insulation and advance cost reduction. The rotor manufacturing method includes forming permanent magnet pieces (60) by dividing a permanent magnet (50), arranging and resin-molding the permanent magnet pieces (60) to form a magnet assembly (40), and placing the magnet assembly (40) in a rotor (10). The method includes placing the permanent magnet pieces (60) all together in a molding die (200) for use in resin-molding, and moving the permanent magnet pieces (60) by a moving means provided in the molding die (200) to move the permanent magnet pieces (60) within the molding die (200), thereby forming the magnet assembly. |
