Single body motor/generator dual function device
First Claim
1. 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.

Abstract
A dual function motor/generator includes a rechargeable battery, a mode switching device, a dual function rotor/stator structure, at least two transmission devices and a clutch device for selecting one of the two transmission devices depending on whether a motor or generator mode is selected. When the dual function motor/generator is used as a motor, power is supplied from the rechargeable battery controlled by the mode switching device to a driven load through the rotor/stator structure and one of the transmission devices, and when used as a generator, the battery is recharged by applying an external force to the load such that the load drives the other transmission device to rotate the rotor in a direction opposite a direction of rotation of the rotor in the motor mode, and thereby induce an electric current in the rotor/stator structure to recharge the battery.
