The one-way clutch connects the input rotor to the output rotor such that the input rotor and the output rotor are rotatable together with each other when a rotation speed of the input rotor exceeds a rotation speed of the output rotor, and that disconnects the input rotor from the output rotor when the rotation speed of the input rotor falls below the rotation speed of the output rotor. The one-way clutch has a rotation speed limiter that disconnects the input rotor from the output rotor when the rotation speed of the output shaft exceeds a predetermined value.

  • Publication number: 20130278096
    Abstract: A hybrid induction motor includes an inductive rotor and an independently rotating permanent magnet rotor. The inductive rotor is a squirrel cage type rotor for induction motor operation at startup. The permanent magnet rotor is axially displaced and variably coupled to the inductive rotor (or to a motor load) through a clutch and is allowed to rotate independently of the inductive rotor at startup. The independently rotating permanent magnet rotor quickly reaches synchronous RPM at startup. As the inductive rotor approaches or reaches synchronous RPM, the coupling between the inductive rotor and the permanent magnet rotor increases until the two rotors are coupled at the synchronous RPM and the motor transitions to efficient synchronous operation.

  • Publication number: 20130221778
    Abstract: A double drive shaft motor has a field rotor supported by a first rotating shaft, a magnetic induction rotor supported by a second rotating shaft, a stator supported by a motor housing casing, a first rotation limitation section arranged between the motor housing casing and the first rotating shaft, a magnetic bi-directional clutch arranged between the motor housing casing and the second rotating shaft, and a magnetic bi-directional clutch arranged between the first rotating shaft and the second rotating shaft. Each magnetic bi-directional clutch operates by receiving a rotational force supplied from the corresponding rotating shaft without using any outside energy to maintain a connection state of the corresponding rotating shaft. The first rotation limitation section is a one-way clutch without requiring any electric control. This makes it possible to make plural operation states, for example, eight operation states from an engine start to an EV drive of a vehicle.

  • Publication number: 20130147207
    Abstract: A starter comprises an electric motor which drives a rotor shaft, a drive shaft that can be rotationally coupled to the rotor shaft, and a pinion mounted on the drive shaft and movable in a translational movement between a rest position and an active position by a movement system. The starter comprises a coupling system that couples a rotary movement in one direction of rotation of the rotor shaft to the pinion. The coupling system moves from an uncoupled state into a coupled state and vice versa. In the coupled state, the rotor shaft is firmly attached to the pinion in the starting direction of rotation. In the uncoupled state, the pinion is disconnected from the rotor shaft in both directions of rotation. The starter further comprises a movement system for moving the pinion from the coupling system into the uncoupled state as it moves the pinion into active position.

    Abstract: A hybrid transmission includes a transmission housing and a motor/generator stator configured to be attached to the transmission housing. A clutch housing is configured to be attached to the motor/generator stator, such that the clutch housing is not directly attached to the transmission housing but is statically fixed. An axis of rotation defines a coordinate system having axial, radial, and clocking rotations. A first piloting feature may be formed on the clutch housing and a second piloting feature on the transmission housing. The first and second piloting features cooperate to axially and radially orient, but not attach, the clutch housing relative to the transmission housing. Third and fourth piloting features cooperate to orient the clocking rotation of the clutch housing. Stator bolts may permanently locate and attach the motor/generator stator to the transmission housing, and clutch bolts permanently locate and attach the clutch housing to the motor/generator stator.

    Abstract: A hand crank generator includes a crank, a gear transmission, and a generation motor generator driven by the gear transmission. The crank and the gear transmission are coupled to each other. A clutch gear is coupled between the crank and the gear transmission. The crank is manually driven to further drive the gear transmission, and the generation motor generator is driven to generate electric current through the clutch gear. When the cranking stops, the clutch gear disengages from a motor generator gear disposed on the generation motor generator. A weighted wheel continues to revolve under inertia for a while to drive the generation motor generator to keep on generating electric current, so that the purpose of saving manual efforts can be achieved.
