  • Hybrid system of engine and motor generator
    Patent number: 8961366
    Abstract: An engine is provided with an output shaft and a motor generator connection shaft of a crankshaft at ends of a crank case and adapted such that the output shaft can be connected with an external driven apparatus. A motor generator has stators relatively fixed to the crank case and a rotor coupled with the motor generator connection shaft and rotating relative to the stators. An external apparatus connection shaft is connected with the rotor and disposed at an end of the motor generator on the opposite side of the engine. A clutch is disposed between the motor generator connection shaft and the rotor. A power storage unit stores electric power generated by the motor generator and supplies the electric power to the motor generator. A controller switches between an electric power generation function and a motor function, and engages and disengages the clutch.
