Abstract
A photonically powered electromagnetic generator is provided. In another aspect, a generator includes a photon source configured to emit photons, a photovoltaic cell configured to receive the photons, a rotor including a yoke and wire windings, a stator surrounding the rotor, and the rotor being configured to create electromagnetism due to its receipt of electricity from the photovoltaic cell when the photovoltaic cell receives the photons, without the use of a brush and without the use of a permanent magnet.
Claims23
A generator comprising:
- a photon source configured to emit photons;
- a photovoltaic cell configured to receive the photons;
- a rotor including a yoke and wire windings;
- a stator surrounding the rotor;
- and
- the rotor being configured to create electromagnetism due to its receipt of electricity from the photovoltaic cell when the photovoltaic cell receives the photons, without the use of a brush and without the use of a permanent magnet.
A generator comprising:
- a photovoltaic receiver;
- a laser or LED light source emitting light to the photovoltaic receiver;
- a rotor electrically connected to the photovoltaic receiver;
- a stator surrounding the rotor;
- the light source and the photovoltaic receiver being located within an optics housing attached to a drive housing containing the rotor and the stator;
- the rotor creating electromagnetism and rotating within the stator when the photovoltaic receiver sends electricity to the rotor, without the use of a brush and without the use of a permanent magnet;
- and
- the electromagnetism ceasing substantially simultaneously when the light ceases to be sent to the photovoltaic receiver.
A generator comprising:
- a photon source configured to emit photons;
- a photovoltaic cell configured to receive at least a majority of the photons;
- a rotor including teeth and wire windings, the wire windings being electrically connected to the photovoltaic cell;
- a stator surrounding the rotor;
- a photosensor;
- the rotor rotating within the stator when the photovoltaic cell sends electricity to the rotor, without the use of a brush and without the use of a permanent magnet;
- and
- a slotted position indicator, the position indicator rotating with the rotor, the photon source emitting some of the photons through at least one slot in the position indicator, and the photosensor sensing the photons passing through the position indicator to assist in determining a rotational position of the rotor.
