Abstract: A subsea pump assembly includes a tubular conduit that has an upstream end plate and an inlet for flowing well fluid into an interior of the conduit. A power cable opening extends through the upstream end plate. An electrical submersible pump and motor are in the interior of the conduit. The motor has a motor assembly housing with an upstream end having an electrical insulator opening. An end connection secures the upstream end to an interior side of the upstream end plate with the insulator opening registering with the power cable opening. An insulated electrical connector is mounted in the insulator opening. A motor wire in the motor assembly housing joins to an inner end of the electrical connector. A power conductor extends from exterior of the conduit through the power cable opening and joins to an outer end of the electrical connector.

Abstract: An integrated circuit for controlling operation of a motor of a fan assembly. The fan assembly includes a housing and a fan. The motor is in the housing. The housing is void of sensors. The motor is configured to rotate the fan. The integrated circuit includes a detection module and a first control module. The detection module is separate from the fan assembly. The detection module is configured to detect a voltage induced in a first coil of the motor or a back electromotive force received from the first coil of the motor. The first control module is configured to receive a control signal from a second control module and control the operation of the fan based on (a) the control signal, and (b) the voltage induced in the first coil of the motor or the back electromotive force. The second control module is separate from the integrated circuit.

Abstract: A fluid pump includes a hollow housing, an electric motor having an armature with a commutator, a pump section rotationally coupled to the electric motor for receiving fuel at a relatively low pressure through a fuel inlet and pressurizing the fuel to a relatively high pressure, a motor brush is in electrical contact with the commutator and including a shunt wire extending therefrom, and an end cap that closes one end of the housing and defines a high pressure chamber with the housing. The end cap includes a hollow brush tower extending therefrom and defining a brush holder slidably receiving the motor brush therein such that the brush holder defines in part the high pressure chamber. The end cap also includes an aperture with the shunt wire extending therethrough such that the shunt wire is sealed with the aperture to prevent the fuel from passing therethrough.

Abstract: A submersible electrical motor that drives a pump has an electrical connector receptacle base. A plug opening extends from the base into an interior of the motor and has a side wall extending around a plug opening axis. An electrical connector plug at an end of a motor lead has a nose portion that stabs into the plug opening and is surrounded by the side wall. An inward facing shoulder formed in the side wall faces inward into the motor. An outward facing shoulder on the nose portion faces outward from the motor interior and registers with the inward facing shoulder when the nose portion is fully received within the plug opening. A retainer inserts into engagement with the inward and outward facing shoulders to prevent outward movement of the plug in the plug opening. The retainer may be a pin or a ring.
