  • Publication number: 20200052567
    Abstract: In a method of manufacturing a first magnet assembly, magnets each including a plating layer on a surface of the magnets are used as a first magnet, a second magnet, and a third magnet. In addition, the first magnet, the second magnet, and the third magnet are disposed in a first direction with same poles facing each other, a frame is brought into contact with the magnets in a second direction, and the frame and the magnets are gripped by a jig. Next, the magnets and the frame are welded to each other. After that, the grip of the jig is released and the jig is separated from the magnets and the frame. Thereafter, an adhesive is applied to the magnets and the frame.
