Abstract
An electrical submersible pump assembly has modules including a pump, upper and lower tandem motors, and a pressure equalizer coupled to the motors. A thrust bearing support member is provided in the lower tandem motor and has a central counterbore with a thrust bearing located in the counterbore. Motor wire holes extend axially through the thrust bearing support member and are spaced radially outward from the counterbore. Motor wires of the lower tandem motor extend through the motor wire holes. A plurality of slots extend radially from the motor wire holes to the counterbore. Each of the slots have an axial length at least equal to an axial length of each of the motor wire holes, and a width greater than a diameter of each of the motor wires of the lower tandem motor.
