  • Active and passive refrigeration systems for downhole motors
    Patent number: 10822932
    Abstract: A pumping system has a motor, a shaft assembly connected to the motor, a production pump connected to the shaft assembly and driven by the motor, an electrical generator connected to the shaft assembly and driven by the motor, an oil circulation pump connected to shaft assembly and driven by the motor, and a heat exchanger. The heat exchanger includes an outer housing, a heat exchange core inside the outer housing, a plurality of heat exchange fluid passages extending through the heat exchange core, and one or more thermoelectric cooling modules in contact with the outer housing and the heat exchange core. The one or more thermoelectric cooling modules are powered by the output from the electrical generator. The oil circulation pump circulates motor lubricant oil between the motor and the heat exchanger.

  • HYBRID MOTOR AND AN ASSOCIATED METHOD THEREOF
    Publication number: 20180233970
    Abstract: A hybrid motor includes a motor shaft, a stator comprising a stator core, a plurality of stator windings wound around the stator core, and a plurality of stator bearings for supporting the motor shaft against the stator core. The hybrid motor further includes a rotor disposed within the stator. The rotor includes a plurality of rotor core segments disposed along an axial direction and coupled to the motor shaft. The plurality of rotor core segments includes a damping rotor core segment and a synchronous rotor core segment. The rotor also includes a plurality of rotor bearings for supporting the motor shaft against plurality of rotor core segments.
