Abstract
A permanent magnet manufacturing method according to an embodiment includes a heating step of disposing a field magnet part near a to-be-magnetized object, the field magnet part having a plurality of permanent magnets for magnetization arranged at predetermined intervals to apply a magnetization magnetic field to the to-be-magnetized object and heating the to-be-magnetized object to a temperature equal to or higher than the Curie point of the to-be-magnetized object, and a magnetization step of cooling the to-be-magnetized object having reached the temperature equal to or higher than the Curie point to a temperature lower than the Curie point and continuously applying a magnetization magnetic field to the to-be-magnetized object by the field magnet unit, and the permanent magnets for magnetization are isotropic SmCo sintered magnets in a predetermined shape.
