1. 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.

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.
