  • Patent number: 10103600
    Abstract: A flywheel based energy storage system which can include one or more flywheels and a motor/generator unit is disclosed. The system can include a universal joint connecting a suspended flywheel and motor/generator to another body (e.g., frame or mounting point on another structure).

  • Patent number: 10063115
    Abstract: Provided is a rotor for use in an inner rotor-type motor, comprising a plurality of magnets arranged in a circumferential direction around the center axis, and a rotor core formed of a magnetic material. The rotor core has an inner core part and a plurality of outer core parts. The plurality of outer core parts and the plurality of magnets are alternately arranged in a circumferential direction at a radially outer side of the inner core part. The magnet has a pair of circumferential end surfaces which are magnetic pole surface, and at least one of them is a protruded surface. Also, the magnet has a portion of which circumferential width is wider than a circumferential width of an outer end surface. For this reason, the volume of the magnet can be increased and the magnetic force of the rotor can be increased, without the need to increase the diameter of the rotor. As a result, when such rotor is incorporated into a motor, the torque of the motor can be improved.
