<p>PROBLEM TO BE SOLVED: To provide a manufacturing device capable of obtaining a rotor for a magnet-inclusion type motor that is excellent in magnetic balance and rotation balance.SOLUTION: A device of manufacturing a rotor for a magnet-inclusion type motor, comprises: a housing part (10) housing a rotor core (R1); a plurality of orientation yokes (11, etc.) arranged uniformly around the housing part, and guiding an orientation magnetic field to be applied to slots (s1, etc.) of the rotor core; and an orientation magnetic field sources (m11, etc.) arranged around the orientation yokes and that is a magnetomotive source of the orientation magnetic field. An anisotropic bonded magnet is filled and molded in the slot of the rotor core, and thereby, a magnetic pole can be formed. The housing part consists of a cylindrical mold (1) in which a magnetic permeable part (11c) having an integrally-continuous inner peripheral surface surrounding an outer peripheral surface of the rotor core and having a small magnetic resistance, and a magnetic shielding part (11b) having a magnetic resistance larger than that of the magnetic permeable part, are alternately and uniformly arranged in a circumferential direction.</p> |
