Abstract:
A single body motor/generator dual function device comprising a rechargeable battery, a switching means for switching between a motor mode and a generator mode, a rotor and stator structure including a rotor and a stator, at least two transmission devices and a forward/reverse clutch means for selectively connecting one of said two transmission devices between said rotor and a power output device connected to a load depending on whether said motor/generator is in said motor mode or said generator mode,wherein when the switching means is located at a first position, power is supplied from the rechargeable battery to the rotor and stator structure, and a first of the two of the transmission devices is connected between the rotor and the power output device such that the rotor transmits power to the output device through the first transmission device, and wherein when the switching means is located at the second position, the rotor and stator structure is used as a generator, and the battery is recharged upon applying external force to the load and selecting a second of said two transmission devices such that the load drives the second transmission device to rotate the rotor and induce an electromotive force that recharges the battery.
