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 selecting one of said two transmission devices corresponding to a selected one of said modes, wherein when the switching means is located at a first position, the rotor and stator structure is used as a motor, wherein power is supplied from the rechargeable battery to a driven load through the rotor and stator structure and one of the transmission devices, and when the switching means is located at the second position, the rotor and stator structure is used as a generator, wherein the battery is recharged upon applying external force to the load and selecting the other of said two transmission devices such that the load drives the 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.
