Patent number: 9793768Abstract: A rotor has a projection part projected from an inner wall of a central hole part toward a central axis and a rib part defined between opening parts adjacent with each other in a circumferential direction. A first imaginary straight line is defined to extend from the central axis outward in a radial direction through a center of the projection part. The projection part is formed so that the first imaginary straight line passes the opening part. A second imaginary straight line is defined to extend from the central axis outward in the radial direction through a center of the rib part. The rib part is formed so that the second imaginary straight line passes a center of a pole part or an intermediate position between pole parts adjacent with each other in the circumferential direction.Type: GrantFiled: August 4, 2014Date of Patent: October 17, 2017Assignee: DENSO CORPORATIONInventors: Asuka Tanaka, Tatsuya Inagaki

Patent number: 9431859Abstract: A motor is provided having a consequent-pole type rotor that has soft magnetic material poles and magnetic poles positioned around the rotor in an alternating manner. A convex surface on each of the poles is formed as a surface in which a midpoint of the convex surface has a radial distance from the rotation axis that is greater than a radial distance of the circumferential edges of the convex surface from the rotation axis. A radial width of a first magnetism transfer part of a cylindrical yoke and a radial width of a second magnetism transfer part of the magnetic pole fulfill a relationship such that an appropriate balance of the magnetic resistance between the first magnetism transfer part and the second magnetism transfer part is achieved. As a result, cogging torque is reduced without reducing output torque.Type: GrantFiled: December 27, 2013Date of Patent: August 30, 2016Assignee: DENSO CORPORATIONInventors: Makoto Taniguchi, Hiroki Tomizawa, Tatsuya Inagaki, Masahiro Goto

Publication number: 20140145564Abstract: A housing and a rotary shaft of a motor are formed of non-magnetic material. A soft magnetic member is provided between a first axial end surface of a fixed core and a bearing. The soft magnetic member is provided on the fixed core side relative to the first bearing thereby to suppress magnetic flux leaking to a vicinity of one end part of the rotary shaft by leading the magnetic flux, which is generated from a rotor, to the rotor core through the fixed core and a casing. A magnetic angular position sensor fixed to one end part of the rotary shaft can detect a magnetic angular position of the rotor accurately without being affected by external magnetic field. As a result, noise generated by vibration of the motor can be suppressed.Type: ApplicationFiled: September 16, 2013Publication date: May 29, 2014Applicant: DENSO CORPORATIONInventors: Makoto TANIGUCHI, Jirou HAYASHI, Tatsuya INAGAKI, Akihito NAITOU, Hiroki TOMIZAWA, Masaaki YAMADA, Masashi YAMASAKI, Yasufumi MATSUO, Shuhei MIYACHI, Nobuhiko URYU

Patent number: 7755907Abstract: An upper lid and a bottom lid are fastened to flange portions formed in outer side surfaces of a casing main body. A metal collar to which a screw serving as pressing means (a fastening member) is inserted is embedded in each flange portion. Both end portions of each of the metal collars protrude at a predetermined length toward the upper lid and the bottom lid from the flange portion. A predetermined interval corresponding to the length of the protruding portion of the metal collar is created between the casing main body and the upper lid and between the casing main body and the bottom lid, by bringing the upper lid and the bottom lid into contact with the protruding portions of each of the metal collars at a time of assembling.Type: GrantFiled: February 13, 2007Date of Patent: July 13, 2010Assignee: Jtekt CorporationInventor: Tatsuya Inagaki
