  • Motor device
    Patent number: 10491084
    Abstract: Provided is a motor device that makes the influence of noise more equal between two signal processing circuits. A rotation angle sensor has a bias magnet, a magnetic sensor unit, a first signal processing circuit, and a second signal processing circuit. The first signal processing circuit is placed symmetrically with the second signal processing circuit in a longitudinal direction of a substrate with respect to the magnetic sensor unit located on a line extended from a central axis of a rotary shaft. An inverter is also placed symmetrically with an inverter in the longitudinal direction of the substrate with respect to the magnetic sensor unit.
    Type: Grant
    Filed: July 3, 2017
    Date of Patent: November 26, 2019
    Assignee: JTEKT CORPORATION
    Inventors: Kohei Ishikura, Tsutomu Hibi
