Signal Bypass Routed Through a Motor of an Electrical Submersible Pump

摘要

An electrical submersible pumping system includes a well fluid pump driven by a three-phase motor. The motor has a stack of motor laminations mounted in a housing. The motor laminations have axially aligned slots spaced circumferentially around a bore. Motor windings are wound through the slots for receiving three-phase power provided to the motor. At least one set of three control lines extend axially through the motor laminations radially outward from the bore and equally spaced around the axis, The control lines may extend through channels on the outer diameter of the motor laminations. The control lines may also extend through the same slots that contain the windings. The control lines extend to a downhole element below the motor for controlling the downhole element.

1. An electrical submersible pumping (“ESP”) system comprising:
a well fluid pump: a three-phase motor operatively connected to the pump and comprising; a housing having a longitudinal axis; a stack of motor laminations mounted in the housing, the motor laminations having axially aligned slots spaced circumferentially around a bore; motor windings wound through the slots for receiving three-phase power provided to the motor; and at least one set of three control lines extending axially through the motor laminations radially outward from the bore and equally spaced around the axis.
