US Classification:

310 74, 31015612, 310 905

Abstract:

An electric machine includes a generally annular outer rotor supported to rotate about a rotational axis. The outer rotor defines an internal cavity therein and has a plurality of permanent magnets in the internal cavity generating a first magnetic field. An inner rotor is in the internal cavity and is supported to rotate about the rotational axis. The inner rotor has a plurality of permanent magnets about its perimeter that generate a second magnetic field. A generally annular stator is in the internal cavity between the outer rotor and the inner rotor. The stator has a stator winding supported by a non-magnetically conductive stator core. The stator winding is arranged to generate a field that interacts with the first and second magnetic fields. One of the outer rotor or the inner rotor is mechanically coupled to drive a load. The other of the outer rotor or the inner rotor is not mechanically coupled to drive the load.

Abstract:

A downhole-type device includes an electric machine. The electric machine includes an electrical rotor configured to couple with a device to drive or be driven by the electric machine. An electrical stator surrounds the electric rotor. The electric stator includes a seal configured to isolate stator windings from an outside, downhole environment. An inner surface of the seal and an outer surface of the electric rotor define an annulus exposed to the outside environment. A bearing couples the electric rotor to the electric stator. A lubrication system is fluidically coupled to the downhole-type device. The lubrication system includes a topside pressure pump and a downhole-type distribution manifold configured to be used within a wellbore. The distribution manifold is fluidically connected to the topside pressure pump and the bearing to receive a flow of lubricant from the topside pressure pump.

International Classification:

E21B 43/12
E21B 33/12

Abstract:

An electric motor is configured to be positioned in a well. The motor includes a housing flooded with an incompressible fluid, a seal, a stator in the housing, and a rotor-impeller. The housing is configured to affix to a tubing of the well. The housing defines an inner bore having an inner bore wall continuous with an inner wall of the tubing for flow of well fluid. The housing defines a port that can be in fluid communication with the well. The seal seals the port against ingress of fluid. The seal is movable by the well fluid to apply a pressure on the incompressible fluid to equalize pressure between the incompressible fluid and the well fluid. The rotor-impeller is configured to be positioned within the inner bore of the housing. The rotor-impeller is configured to be retrievable from the well while the stator remains in the well.

Abstract:

A downhole-type system includes a rotatable shaft, a downhole-type magnetic bearing coupled to the rotatable shaft, a downhole-type sensor, a surface-type controller, and a surface-type amplifier coupled to the magnetic bearing. The magnetic bearing can control levitation of the rotatable shaft. The downhole-type sensor can detect a position of the rotatable shaft in a downhole location and generate a first signal based on the detected position. The surface-type controller can receive the first signal, determine an amount of force to apply to the shaft, and generate a second signal corresponding to the determined amount of force. The surface-type amplifier can receive the second signal, amplify the second signal to a sufficient level to drive the magnetic bearing to apply force to the rotatable shaft to control the levitation of the rotatable shaft at the downhole location, and transmit the amplified second signal to the magnetic bearing.
