PROBLEM TO BE SOLVED: To impart flexibility to motor characteristic by obtaining a variety of magnetizing patterns. SOLUTION: In this magnet magnetizing device, an outer peripheral side magnetizing yoke 41 having a plurality of winding parts C11, C12,... is arranged along the circumferencial direction on the outer peripheral surface side of a cylindrical magnet 40, and an inner peripheral side magnetizing yoke 42 having a plurality of winding parts C21, C22,... is arranged along the circumferencial direction on the inner peripheral surface side of the magnet 40. Currents are applied to the respective winding parts of the yoke 41 and the yoke 42, in a specified direction for each of the respective winding parts, and magnetization at specified pitches is executed in the circumferential direction of the outer peripheral surface and the inner peripheral surface of the magnet 40. By variously setting the magnetizing condition like the current direction, particular magnetizing patterns due to the magnetizing condition can be obtained. |
