Abstract
A motor that includes a motor portion structured to house a stator and a rotor mounted to a shaft of the motor. The motor additionally includes a cooling portion disposed adjacent to the motor portion and separated from the motor portion by a structural interface. The cooling portion provides a cooling chamber structured to have a cooling fluid passed therethrough via a cooling fluid moving device that is structured to be coupled to and driven by the motor shaft. Furthermore, the motor includes a plurality of heat pipes having evaporator ends disposed within the motor portion and condenser ends disposed within the cooling chamber. During operation of the motor and cooling fluid moving device, the cooling fluid contacts the heat pipe condenser ends to extract heat from the condenser ends, hence cooling the evaporator ends of the heat pipes, thereby cooling the motor portion of the motor and the stator and rotor housed therein.
