Publication number: 20230296103Abstract: A motor and a fan device are provided. The motor includes a motor bracket; a conductive shaft fixed to a front surface side of the motor bracket; a rotor rotatably supported on the shaft; a stator fixed to the front surface side of the motor bracket inside the rotor and wound with a plurality of coils for generating a magnetic field to rotate the rotor; a substrate, a front surface thereof mounted with a driver circuit for controlling magnetic field generation by the coils; and a driver case fixed to a rear surface side of the motor bracket and forming an accommodation space accommodating the substrate between itself and the motor bracket. A positive wiring of the driver circuit is mounted outside a region on the substrate overlapping the shaft when the motor is viewed from an axial direction of the shaft.Type: ApplicationFiled: February 4, 2023Publication date: September 21, 2023Applicant: MITSUBA CorporationInventors: TAKAHIKO OGANE, SATOSHI TAKEDA, HIROKAZU TAKADA, Satoshi NAGAMOTO, KEIICHI HOSOI

Patent number: 7854093Abstract: An automatic opening/closing apparatus for vehicle, which is provided with a tensioner mechanism for applying a predetermined tension to a cable member, is downsized. A case of a driving unit is provided with a tensioner housing, and the tensioner mechanism for applying the predetermined tension to a cable is accommodated in the tensioner housing. The tensioner mechanism includes a pulley holder movably mounted on a guide shaft, and a spring for biasing the pulley holder, wherein a movable pulley is rotatably supported by the pulley holder. The cable drawn in the tensioner housing is wound about the movable pulley so that a direction in which the cable is drawn out from the case is substantially parallel to a direction in which the cable is drawn out from a driving drum, whereby the predetermined tension is applied to the cable by a spring force of the spring.Type: GrantFiled: January 30, 2008Date of Patent: December 21, 2010Assignee: MITSUBA CorporationInventors: Yasushi Yoshida, Yoshitaka Sekine, Yoshitaka Urano, Hiroshi Eguchi, Satoshi Nagamoto

Patent number: 7815242Abstract: An automatic opening/closing apparatus for vehicle is downsized, and cost of the automatic opening/closing apparatus is reduced by reducing the number of its components. A driving drum is rotatably accommodated in a main body case of a driving unit, and one ends of cables are connected to a sliding door and the other ends are wound around the driving drum. An electric motor is attached to the main body case, and the driving drum is driven for rotation. A tensioner mechanism applying a predetermined tension to the cables is accommodated in the main body case. A control device, including a control substrate and a substrate case for accommodating the control substrate, is disposed to be overlapped on an axial-directional side of the driving drum to a portion of the main body case for accommodating the tensioner mechanism, whereby an operation of the electric motor is controlled by the control device.Type: GrantFiled: January 30, 2008Date of Patent: October 19, 2010Assignee: Mitsuba CorporationInventors: Yasushi Yoshida, Yoshitaka Sekine, Yoshitaka Urano, Hiroshi Eguchi, Satoshi Nagamoto
