Abstract
A lift fluid driven downhole electrical generator and method for generating and controlling the electrical output from the electrical generator is disclosed. The electrical generator comprises a housing having a lift fluid port in a sidewall portion thereof for allowing the flow of lift fluids therethrough. A rotor is rotatably disposed within the housing. The rotor converts lift fluid pressure to rotary motion when the lift fluid travels through the lift fluid port and impinges the rotor. The electrical generator also includes an electromagnetic assembly having a first portion that is rotatable with the rotor and a second portion that is stationary with the housing. The electromagnetic assembly converts the rotary motion to electricity as the first portion of an electromagnetic assembly rotates relative to the second portion of the electromagnetic assembly.
