This disclosure describes various implementations of a downhole-blower system that can be used to boost production in a wellbore. The downhole-blower system includes a blower and an electric machine coupled to the blower that can be deployed in a wellbore, and that can, in cooperation, increase production through the wellbore.

A turbocharger system for an engine includes a rotor, a primary bearing system arranged to axially and radially support the rotor to rotate on a central rotational axis, a compressor coupled to a rotor to rotate with the rotor, a turbine coupled to the rotor to rotate with the rotor, and an electromagnetic actuator adjacent to the rotor. The electromagnetic actuator selectively acts on the rotor and supplements the axial support of the primary bearing system by applying a magnetic force on the rotor in a direction parallel to the central rotational axis of the rotor.

A fluid pumping and energy recovery device may include a housing that defines an impeller chamber and a motor/generator chamber. An impeller may reside within the impeller chamber; and a motor/generator may reside in the motor/generator chamber. The motor/generator may include a stator and a rotor. The rotor may be coupled to the impeller and supported (e.g., by magnetic bearings) to rotate in the stator. The rotor may generate electrical power in a generating mode and rotate in response to electrical power applied to the stator in a motoring mode. Seals may be adapted to hydraulically isolate the pump chamber from the motor/generator chamber by sealing against a rotating surface of the device. In certain instances, sealing is achieved using a bidirectional seal.

An electric machine system includes an electric machine and a companion device. The electric machine has a stationary member and a movable member that, by interaction of magnetic fields, at least one of moves relative to the stationary member or generates electricity when moved relative to the stationary member. One of the stationary member and the movable member includes a permanent magnet. The companion device is coupled to the electric machine to communicate mechanical movement with the movable member. In certain instances, the electric machine system has adaptations for operation of the electric machine system subsea and/or in a corrosive environment.
