摘要： Systems and methods for constructing electric motors in which a stator core includes inner and outer portions that enable slots for magnet windings to be open during construction and closed in the completed motor. One embodiment comprises a method in which an inner stator core having a plurality of slots is formed by stacking a set of laminations. The slots are open radially outward from an axis of the inner stator core and which are configured to accommodate turns of magnet wire. After the magnet wire is positioned in the open slots, an outer stator core comprising stacked laminations is positioned around the inner stator core, enclosing the slots. The inner and outer stator cores are then positioned within a housing and assembled into a downhole motor.

摘要： An electrical motor for an electrical submersible pump wherein the electrical motor has increased heat transfer capabilities. The electrical motor includes a housing and a plurality of stator laminations within the housing. Each stator lamination defines a central orifice and a plurality of lamination slots. A plurality of magnet wires pass through each of the plurality of lamination slots formed by the stacked plurality of stator laminations. Shrink wrap surrounds each of the plurality of magnet wires to secure the magnet wires in bundles. The result is that the wires are effectively bound together in a manner that allows oil to move freely inside the lamination slots surrounding the wire bundles. Since fluid can pass between and around the windings, the overall winding temperature will be normalized, essentially reducing hot spots that occur in prior art designs.

摘要： A submersible electric pump motor comprises an unvarnished stator structure having stator windings formed of conductors. The stator windings form end coils at each end of the stator for each phase. The end coils are tied to three arc-shaped, metal segments, each having an opening and positioned circumferentially within a circumferential groove. The metal segments are welded to the interior of the housing to provide a rigid surface. High temperature strings are wound through the openings in each metal segment and around the end coils for each phase to tie each end coil of that phase to that metal segment. This prevents the end coils of each phase from twisting during startup, sliding into the slots, and moving inwards towards a rotating rotor.

摘要： A power line for an electrical submersible pump has three metallic impermeable tubes. A single electrical conductor is located within each of the tubes. Each conductor has at least one elastomeric insulation layer surrounding it. An annular portion of the insulation layer of each of the electrical conductors is in tight contact with the tube to form a seal. The annular portions may be annular crimps formed in the tube at intervals. The annular portion could also be a continuous seal caused by swelling of the insulation layer due to contact with a hydrocarbon.

摘要： An electrical motor for a submersible well pump assembly has a brush for preventing arcing across the bearings. The motor has a housing and a stator stationarily mounted in the housing. A shaft extends through a cavity in the stator, the shaft carrying a rotor. Bearings are located at the base and head of the pump for stabilizing the shaft in the housing. A brush is stationarily carried by the housing in electrical common with the stator in the housing. The brush is also in sliding engagement with the shaft. The brush is located near one of the ends of the housing to reduce arcing across the bearing because of voltage differential between the shaft and the stator.

摘要： An inducer pump located internally in an electrical submersible pump motor enhances lubricant circulation within the motor. The inducer is located at the lower end of the shaft within a shaft bore. The inducer has a rod and a helical flight rigidly mounted to the rod. The inducer rotates in unison with the motor, pumping lubricant from a lower lubricant chamber upward through the shaft bore.

摘要： An electrical submersible pump assembly has a motor module coupled to a centrifugal pump module by a seal section module. A shaft assembly extends through each of the modules for causing the motor module to rotate the pump module. At least one of the modules has a sleeve extending around the shaft that is of a harder material than the shaft. A torque transmitting ring is deformed between an inner diameter of the sleeve and an exterior portion of the shaft. The inner diameter of the sleeve is a continuous cylindrical surface free of any torque transmitting shoulders. Friction created by the torque transmitting ring transmits the entire rotational force from the shaft to the sleeve.

摘要： A submersible well pump motor has features to prevent the carrier bearing from sliding axially along the stator due to thermal growth of the rotor. The rotor has a shaft and rotor sections spaced apart from each other. Carrier bearings are located between the rotor sections, each having an anti-rotation member that frictionally engages the inner diameter of the stator to prevent spinning of the carrier bearing. A deflectable thrust washer may be located between ends of the carrier bearing and the rotor sections. The thrust washer reduces in thickness in response to an axial thermal growth force due to axial thermal growth movement of the rotor sections and shaft. The thermal growth force is less than an amount of dislodging force required to cause the anti-rotation member to axially move relative to the stator. Rather than deflectable thrust washers, sacrificial thrust washers that dissolve prior to normal operation may be used.
