Patent number: 11764626Abstract: A rotor includes a rotor core, a plurality of magnets positioned radially outside the rotor core, a rotor cover having a tubular portion surrounding the rotor core and the magnet, and a resin portion coupling the rotor core and the magnet with each other. The resin portion has a first lid portion positioned on one axial side of the rotor core and the magnet. The rotor cover has a flange portion projecting radially inward from the tubular portion on one axial side of the first lid portion. The first lid portion has a recess portion depressed from a surface on one axial side of the first lid portion. The recess portion is positioned at a position overlapping between the circumferentially adjacent magnets. The flange portion has a first swage portion swaged to the other axial side and positioned inside the recess portion.Type: GrantFiled: August 2, 2019Date of Patent: September 19, 2023Assignee: NIDEC CORPORATIONInventors: Masato Aono, Hideaki Uchise, Tatsuya Ito

Patent number: 11760184Abstract: A pipe connection portion of a damper case has an opening opened toward the rear side. In an end surface around the opening in the pipe connection portion, a recess is formed in an inner diameter portion. The recess is recessed to the front side as compared to another portion of the end surface. In an end surface of a pipe member, a groove portion is formed in an outer diameter portion. The groove portion is recessed to the rear side as compared to another portion of the end surface. A first seal member and a second seal member are interposed between the end surface of the damper case and the end surface of the pipe member, and the damper case and the pipe member are sealed by the seal members in a liquid-tight manner.Type: GrantFiled: October 14, 2021Date of Patent: September 19, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Manabu Oshida, Hideaki Uchise, Yuya Fujiwara

Patent number: 11271448Abstract: A stator includes a stator core, an insulator attached to the stator core, and coil wires. The insulator includes base portions respectively surrounding outer peripheral surfaces of teeth and an outer wall portion located immediately above the core back and extending in a circumferential direction. Each of the coil wires includes coils into which each of the coil wires is wound around more than one of the teeth by concentrated winding, a connecting wire connecting the coils, and a pair of lead wires located at two ends of each of the coil wires and extending from the coils. The connecting wire of each of the coil wires includes at least one outside-passing portion extending along an outer surface of the outer wall portion on a radially outer side of the outer wall portion.Type: GrantFiled: June 25, 2018Date of Patent: March 8, 2022Assignee: NIDEC CORPORATIONInventors: Hideaki Uchise, Takayuki Migita, Hiroshi Kitagaki, Tatsuya Ito, Akihiro Okita

Patent number: 8109742Abstract: A rotor yoke includes a substantially flat or annular flat cover portion coaxial or substantially coaxial with a rotational axis and a substantially cylindrical side wall portion extending from an outer circumference of the cover portion in a parallel or substantially parallel relationship with the rotational axis. The rotor yoke further includes a substantially annular flange portion extending radially outwards from an open end of the side wall portion. The cover portion and the side wall portion define a cup portion whose center of gravity deviates from the rotational axis in a plane perpendicular or substantially perpendicular to the rotational axis, and the flange portion has an outer circumferential circle whose center deviates from the rotational axis in a direction opposite to the deviation direction of the center of gravity of the cup portion.Type: GrantFiled: May 19, 2009Date of Patent: February 7, 2012Assignee: Nidec CorporationInventors: Shinya Tabata, Tadaaki Fujinaga, Yoshitaka Hiraishi, Hideaki Uchise, Takashi Tsukada
