Publication number: 20240047112Abstract: A cylindrical multipole magnet having an inner peripheral surface and an outer peripheral surface and having N- and S-poles alternately and continuously in a circumferential direction. A surface magnetic flux density of the outer peripheral surface is at least 0.2 times a surface magnetic flux density of the inner peripheral surface. The cylindrical multipole magnet contains an anisotropic rare earth magnetic powder and a resin, with a filling ratio of the anisotropic rare earth magnetic powder being at least 50 vol % but not higher than 65 vol % with respect to a total volume of the anisotropic rare earth magnetic powder and the resin.Type: ApplicationFiled: August 7, 2023Publication date: February 8, 2024Applicant: NICHIA CORPORATIONInventors: Rie YOSHIDA, Daichi ITAMI, Masahiro ABE, Kuniyasu KAWAMURA, Takayuki YANO, Muneo YAMAMOTO

Patent number: 11735358Abstract: A bonded magnet is provided which includes first and second components. The first and second components have first and second non-action surfaces, and first and second action surfaces that intersect the first and second non-action surfaces, respectively. First and second flux groups curve inside the first and second components from the first and second non-action surfaces to the first and second action surfaces, respectively. The areas of the first and second non-action surfaces are greater than the first and second action surfaces, respectively. The flux densities on the first and second action surfaces are higher than the first and second non-action surfaces, respectively. The pole on the first non-action surface is opposite to the second non-action surface. The first and second non-action surfaces are coupled to each other. The first flux groups continuously extend from one to another.Type: GrantFiled: October 19, 2020Date of Patent: August 22, 2023Assignee: NICHIA CORPORATIONInventors: Rie Yoshida, Michiya Kume, Kohei Ihara, Taku Ichimori
