Abstract
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.
