Abstract
A wind generator includes a first rotor disposed with a first axis of rotation for converting wind energy into rotational energy and a second rotor disposed with a second axis of rotation different from the first axis of rotation. With sufficient wind, the first rotor provides power to a first field rotor of a generator and the second rotor provides power to a second field rotor of the generator. When the field rotors rotate relative to each other electrical energy is generated.
Claims6
An electrical generator for converting energy from wind into electrical energy comprising:
- a first rotor for converting wind energy into rotational energy and disposed with a first axis of rotation;
- a second rotor for converting wind energy into rotational energy disposed with a second axis of rotation different from the first axis of rotation;
- a generator having;
- a first field rotor in mechanical communication with the first rotor for receiving rotational energy therefrom, and
- a second field rotor in mechanical communication with the second rotor for receiving rotational energy therefrom,
- a first transmission for receiving rotational energy from the first rotor and providing rotational energy to the first field rotor;
- and
- a second transmission receiving rotational energy from the second rotor and providing rotational energy to the second field rotor,
- wherein in use rotation of the first rotor in response to wind causes rotation of the first field rotor in a first direction and rotation of the second field rotor in a response to a wind with approximately same direction and energy causes rotation of the second field rotor in a second opposite directions;
- and wherein each of the first transmission and the second transmission is a variable ratio transmission.
