Abstract:
1. A permanent magnet magnetizing apparatus comprising: a heating section; a magnetizing section axially disposed as a discrete structure from the heating section; and a holding member for holding a magnetization object, the holding member being movable relative to the heating section and the magnetizing section, wherein the magnetization object heated in the heating section is transferred to the magnetizing section and is magnetized therein; and the heating section and the magnetizing section are supported so that at least one of the heating section and the magnetizing section is movable toward and away from the other; and the magnetization object is heated in the heating section when the magnetizing and heating sections are in a spaced-apart relation to each other, the magnetizing and heating sections are brought closer to each other while the magnetization object is still being heated, the magnetization object is then transferred to the magnetizing section to be magnetized therein, and then the magnetizing and heating sections are brought into a spaced-apart relation.
