Patent number: 11909266Abstract: A rotor includes a core and two or more ribs. The core has a through hole group that includes three or more through holes arranged in a circumferential direction. The through hole group is formed through a predetermined magnetic pole. The two or more ribs are configured as portions of the core, with each rib being interposed between adjacent through holes. A first of the ribs has a first inclination with respect to a magnetic pole centerline. A second of the ribs has a second inclination with respect to the magnetic pole centerline. The second inclination is larger than the first inclination. The magnetic pole centerline is a straight line that passes through a radial center line of the magnetic pole and an axial center of the rotor. The first rib is narrower than the second rib.Type: GrantFiled: May 14, 2021Date of Patent: February 20, 2024Assignees: Daikin Industries, Ltd., UNIVERSITY PUBLIC CORPORATION OSAKAInventors: Yoshinari Asano, Yoshihito Sanga, Masayuki Sanada, Shigeo Morimoto, Yukinori Inoue

Patent number: 10189110Abstract: A plurality of cutout members are cut out from a plate blank by a plasma arc generated from a plasma torch by a method including a piercing step and a cutting step. In the piercing step, an aperture is formed on an outer peripheral side of a cutout member by maintaining the plasma torch at a first height from the plate blank on the outer peripheral side of the cutout member while the plasma arc is generated from the plasma torch and by moving the plasma torch relative to the plate blank in a horizontal direction. In the cutting step, a continuous cutting groove is formed along an outer contour of the cutout member by setting the plasma torch at a second height lower than the first height and by moving the plasma torch in the horizontal direction along an incision part and a processing line continuing to the incision part.Type: GrantFiled: March 7, 2013Date of Patent: January 29, 2019Assignees: KOMATSU INDUSTRIES CORPORATION, KOMATSU LTD.Inventors: Yoshihiro Yamaguchi, Satoshi Ohnishi, Katsuo Saio, Kazunori Tsunekawa, Shigeo Morimoto

Patent number: 9800106Abstract: Satisfactory magnet torque is achieved while avoiding a reduction in the reluctance torque generated. The rotor core is provided with a plurality of magnet slots arranged in the circumferential direction of the rotor core and a gap formed of base holes and a projecting hole. The base holes extend from both ends in the circumferential direction of each magnet slot to the outer side of the rotor core. The projecting hole projects in the circumferential direction of the rotor core from at least one of peripheral portions, opposed to each other, of the base holes provided at both of the ends of the magnet slot, when viewed in an axial direction. The projecting hole is located closer to the magnet slot than to an outer peripheral side end of the base hole.Type: GrantFiled: March 4, 2015Date of Patent: October 24, 2017Assignees: DAIKIN INDUSTRIES, LTD., OSAKA PREFECTURE UNIVERSITY PUBLIC CORPORATIONInventors: Toshinari Kondou, Masayuki Sanada, Shigeo Morimoto, Yukinori Inoue
