Abstract
A motor for motorcycles includes a shaft, a rotor, an inner housing covering the rotor, a sun and planet gear unit, a generator, an outer housing, and a clutch as main components. The generator produces electricity to charge a battery when the motor moves the motorcycle so that the battery is always fully charged for operating the motor. The clutch will not engage a wheel of the motorcycle to rotate until rotation of the motor reaches a preset speed.
Claims1
A motor for motorcycles, comprising:
- a shaft;
- a rotor rotatively coupled to said shaft, said rotor having a plurality of conductive poles coupled thereto;
- an inner housing secured to said shaft and enclosing said rotor;
- a pair of carbon brushes secured to said inner housing for electrical coupling with said plurality of conductive poles as said rotor rotates;
- a plurality of magnets disposed within said inner housing adjacent said rotor;
- a sun gear rotatively disposed on said shaft and coupled to said rotor for rotation therewith;
- an electric generator coupled to said sun gear for rotation therewith to provide an electrical output for charging a battery;
- a plurality of planet gears pivotally coupled to an output gear and engaged to said sun gear to rotatably drive said output gear, said output gear being coupled to said shaft;
- an outer housing rotatively coupled to said shaft and secured to a wheel of the motorcycle;
- and,
- a clutch having a clutch body coupled to said outer housing and means coupled to said plurality of planet gears for transmitting rotational forces from said plurality of planet gears to said clutch body responsive to said transmitting means being rotated above a predetermined speed.
