Document Type and Number:
Japanese Patent JP7344098
Kind Code:
B2
Abstract:
To provide a manufacturing method of a permanent magnet capable of heating and magnetizing with lower energy in a shorter time.SOLUTION: A manufacturing method of a permanent magnet rotor includes heating a permanent magnet rotor having a rotating shaft in the center of an iron core and having a magnet before magnetizing in the iron core, and then magnetizing the permanent magnet rotor includes a heating step of heating the permanent magnet rotor to obtain a rotor after heating, a magnetizing step of magnetizing the permanent magnet after heating contained in the rotor after heating to obtain a rotor after magnetizing containing the permanent magnet after magnetizing, and a post-treatment step of passing the rotor after magnetizing through a path made of a soft magnetic material.SELECTED DRAWING: Figure 1
