Abstract:
1. A motor comprising: a frame that defines a motor portion and an adjacent cooling portion that is separated from the motor portion by a structural interface disposed within the frame to define a cooling chamber within the motor cooling portion; an electrical package disposed within the motor portion such that the motor frame encloses the electrical package from exterior elements, the electrical package comprising a rotor and a stator; and a plurality of heat pipes disposed within and fully enclosed by the motor frame, the heat pipes having an evaporator ends disposed within the portion of the frame that defines the motor portion and condenser ends disposed within the portion of the frame that defines the cooling portion, wherein the cooling chamber is structured to have a working fluid introduced therein by a working device that is structured to be driven by the motor shaft and is operable to pump a high volume of the working fluid into the cooling chamber such that at least a portion of the frame defining the cooling portion is cooled via the working fluid introduced into the cooling chamber and via contact with the working device mounted thereto, thereby extracting heat from the heat pipe condenser ends and cooling the motor portion of the motor.
