Abstract: An electrical submersible well pump motor has metal-to-metal sealing for the power cable electrical connection. A conductor passage in the motor head has a conical seat. A motor contact member electrically connected with the motor is located in the conductor passage below the seat. A metal tube has a lower portion that inserts into an upper portion of the conductor passage. A metal sealing ferrule encircles the tube, and a compression nut deforms the ferrule into sealing engagement with the seat and the tube. An electrical conductor extending from the power cable protrudes downward from the tube and has a conductor contact member on a lower end. The motor contact member and the conductor contact member stab into partial engagement with each other, defining a gap between terminal surfaces of the contact members that can close up during operation due to thermal growth.

Abstract: An electrical submersible pump assembly includes a motor having a stator with a bore extending along a longitudinal axis. A shaft with axially spaced apart rotor sections extends longitudinally through the bore. At least one lubricant pump is mounted to the shaft within the bore for circulating motor lubricant within the bore. A bearing carrier has an inner diameter in sliding engagement with an outer diameter of the lubricant pump. An anti-rotation member on an outer diameter of the carrier is in engagement with the bore of the stator to prevent rotation of the carrier.
