  • Publication number: 20190074740
    Abstract: A method of manufacturing a rotor includes: applying the adhesive to an adhesive placement position on an outer peripheral surface of the permanent magnet or an inner peripheral surface of the magnet hole, the adhesive containing an expansive agent that is expanded by being heated to a temperature that is equal to or higher than an expansion temperature; drying the adhesive after applying the adhesive; inserting the permanent magnet into the magnet hole of the rotor core after drying the adhesive; and fixing the permanent magnet and the rotor core to each other using the adhesive by expanding the expansive agent and curing the adhesive by heating the adhesive to a temperature that is equal to or higher than the expansion temperature after inserting the permanent magnet.

  • Patent number: 8272984
    Abstract: An endless metal belt including a ring formed by laminating endless metal plates; and multiple elements continuously attached to the ring. Each of the elements has a body, a head connected to the body by a pillar, and slots formed between the body and the head on left and right sides of the pillar, respectively, for receiving the ring. The elements satisfy the equations (h/t)<1 and (S/h)>40, where h is a width of the slots, t is a plate thickness of the elements, and S is an area of the head.
