Abstract
Providing power to a downhole-type tool includes rotating a rotor of a downhole power unit about a longitudinal axis, generating, with a generator stator assembly of a generator positioned adjacent the downhole power unit, an amount of power in response to rotating the rotor, and supplying, with the generator, the amount of power to at least one downhole-type tool proximate to the downhole power unit. The at least one downhole-type tool is operable using the supplied amount of power.
Claims33
A method for providing power to a downhole-type tool, comprising:
- rotating a rotor of a downhole power unit about a longitudinal axis, the downhole power unit comprising an electric motor comprising an electric stator, and the rotor comprising a permanent magnet;
- generating, with a generator stator assembly of a generator positioned adjacent the downhole power unit, an amount of power in response to rotating the rotor, the generator stator assembly positioned adjacent to the electric stator of the electric motor;
- and
- supplying, with the generator, the amount of power to at least one downhole-type tool proximate to the downhole power unit, the at least one downhole-type tool operable using the supplied amount of power.
A system for providing power to a downhole-type tool, comprising:
- a downhole-type power unit comprising a rotor and an electric motor comprising an electric stator, the rotor comprising a permanent magnet, the rotor configured to rotate about a longitudinal axis;
- a generator comprising a generator stator assembly positioned adjacent to the rotor of the downhole power unit, the generator stator assembly positioned adjacent to the electric stator of the electric motor, and the generator configured to generate an amount of power in response to rotation of the rotor;
- and
- at least one downhole-type tool proximate to the downhole power unit, the generator configured to supply the amount of power to the at least one downhole-type tool, and the at least one downhole-type tool being operable using the amount of power.
A method for providing power to a tool, comprising:
- rotating a rotor of an electric motor about a longitudinal axis;
- generating, with a generator stator assembly of a generator positioned adjacent the rotor of the electric motor, an amount of power in response to rotating the rotor, where the generator comprises a generator rotor, the generator rotor comprises a permanent magnet, the generator rotor is mechanically coupled to the rotor of the electric motor, and the generator stator assembly is positioned surrounding the generator rotor;
- and
- supplying, with the generator, the amount of power to at least one electric device proximate to the electric motor, the at least one electric device operable using the amount of power.
