Patent ID: 7569955

Claim:
An electric motor comprising: a motor portion comprising a stator and a rotor that when energized with electric current, the rotor is caused to rotate by a resulting magnetic field, wherein the motor portion comprises a motor frame that encloses the rotor and stator from exterior elements; a cooling portion adjacent the motor portion and separated from the motor portion by a structural interface, the cooling portion comprising: a cooling chamber filled with a quantity of motor cooling fluid that is prevented by the structural interface from entering an interior of the motor portion; and a mounting plate structured to provide a sidewall of the cooling chamber such that the motor cooling fluid within the cooling chamber of the motor contacts the mounting plate, the mounting plate structured to have a pumping device, driven by the motor, mounted thereto such that a pump medium pumped by the pumping device thermally contacts and cools the mounting plate such that the mounting plate provides an infinite cold plate operable to cool the motor cooling fluid within the cooling chamber of the motor; and a plurality of heat pipes disposed within the motor portion and extending from the motor portion into the cooling chamber such that the motor cooling fluid, cooled by the mounting plate that is cooled by the pump medium, contacts the portion of heat pipes extending within the cooling chamber in order to remove heat from the heat pipes.
