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： Systems and methods for insulating the Y-points of three-phase electric motors commonly used in ESP systems, in which the Y-points are not grounded or tied to a reference voltage, and may consequently experience high voltages. One embodiment is an apparatus for insulating the Y-point of the motor using an electrically insulating enclosure. The enclosure has apertures that extend from a cavity therewithin the to the exterior of the enclosure. The cavity accommodates the Y-point of the motor. The conductors which are connected at the Y-point junction extend from the cavity to the coils of the three-phase motor, and possibly to an instrument package. Seals are formed at the apertures to provide an electrically insulating barrier between the Y-point and the exterior of the enclosure. The cavity may be filled with an insulating material such as potting compound or oil.

摘要： A submersible pump assembly includes a rotary pump and an electrical motor operatively connected to the pump for driving the pump. A seal section is connected between the motor and the pump for reducing a pressure differential between lubricant in the motor and hydrostatic well fluid pressure. A shaft assembly extends from the motor through the seal section and the pump. A sleeve surrounds the shaft assembly. A carrier body has an inner diameter surface. An anti-rotation member is on an exterior of the carrier body in static engagement with an inner diameter surface of the pump assembly for preventing rotation of the carrier body. An annular metal radially deflectable spring is located between and in contact with an outer diameter surface of the sleeve and with the inner diameter surface of the carrier body. The spring is a wave spring with undulations.

摘要： Systems and methods for preventing rotation of rotor bearings in electric motors which enable retrofitting of conventionally designed bearings to use spring-loaded keys instead of elastomeric T-rings to prevent rotation while allowing axial movement of the bearings within a stator bore. An elongated, curved spring arm is positioned in the nesting groove at the outer periphery of the bearing. One end of the spring may be secured to the bearing by positioning an S-shaped bend in the spring arm through a hole in the floor of the nesting groove. A key at the opposite end of the spring arm is urged radially outward by the spring arm. The key may be positioned in a slot in the outer portion of the bearing, and the spring arm may be retained in the groove by a retaining pin installed in the groove.

摘要： The invention includes a retention system and method for stator magnet wires. In embodiments, the retention system includes a packing ring that can swell to a larger size following installation. In embodiments, the lubricant used in the motor causes the packing ring to swell. When the packing ring swells, it exerts pressure against the end turns of the stator magnet wires, and can contour to the shape of the wires so that there are no pressure points on the wires. A rigid support ring can be positioned concentric with the packing ring so that the packing ring does not swell toward the axis of the motor housing.
