  • Patent number: 9709015
    Abstract: A power generation unit includes a motor generator having a rotor with magnet, and a stator with coils driven in a plurality of phases, the coils of the respective phases not being connected to each other; and a driving control part that performs control so that a coil of each phase of the stator is brought into any one of a first state in which torque is generated by the rotor, a second state in which both ends of the coil are electrically released, and a third state in which both ends of the coil are short-circuited.
    Type: Grant
    Filed: December 11, 2013
    Date of Patent: July 18, 2017
    Assignee: HONDA MOTOR CO., LTD.
    Inventors: Katsuhiro Ouchi, Takeshi Yanagisawa, Yutaka Sonoda, Tatsuya Shiozawa, Atsushi Katayama, Hitoshi Kurosaka
  • Patent number: 9637008
    Abstract: A generator motor unit includes a generator motor including a rotor equipped with magnets, and magnetic bodies that protrude from a wall surface, a first stator that makes magnetic flux act on the magnets, thereby generating torque in the rotor, and a second stator that makes magnetic flux act on the magnetic bodies, thereby generating torque in the rotor; and a controller that controls energization of coils of the first stator and the second stator.
