Patent number: 11996731Abstract: A core used in an axial-gap rotating electric device includes an annular back yoke and a plurality of teeth protruding in an axial direction that is perpendicular to a first flat surface of the back yoke. The plurality of teeth are provided on the first flat surface at intervals in a circumferential direction. The back yoke and the teeth are constituted of an integrally-molded powder compact. A first curved section that connects a peripheral surface of each tooth and the first flat surface of the back yoke is provided at a corner between the tooth and the back yoke. The first curved section has a curvature radius ranging between 0.2 mm and 1.5 mm inclusive.Type: GrantFiled: September 5, 2019Date of Patent: May 28, 2024Assignees: SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO ELECTRIC SINTERED ALLOY, LTD.Inventors: Tatsuya Saito, Tomoyuki Ueno, Hijiri Tsuruta, Yuichi Nakamura, Yuka Fukunaga
