Abstract

The disclosed lift pump employs a unique arrangement of conductive studs to transmit the three phases of motor power from the control board to the brushless motor. The conductive studs penetrate the wall of the motor/pump enclosure, which is otherwise non-conductive. The conductive studs are intentionally larger than needed to transmit the current used by the motor, and are arranged in thermal contact with heat conductive portions of the motor control board to transmit heat from the control board into the motor/pump enclosure where heat is transmitted to fuel passing through the assembly. An additional center heat sink is situated in a position aligned with heat generating capacitors that are part of the motor drive circuitry on the motor control board.
