Abstract
A motor including a frame that defines a motor portion and an adjacent cooling portion, and a plurality of heat pipes disposed within and fully enclosed by the motor frame. Each heat pipe has an evaporator end disposed within the portion of the frame that defines the motor portion and a condenser end disposed within the portion of the frame that defines the cooling portion. A cooling chamber within the motor cooling portion is structured to have a fluid introduced therein by a working device such that at least a portion of the frame defining the cooling portion is cooled via the working fluid, thereby extracting heat from the heat pipe condenser ends and cooling the motor portion of the motor.
