Abstract : The purpose of the program was to demonstrate the feasibility of operating electric motors at higher power densities than attainable in motors of conventional design. An investigative phase of this program covered a variety of electromagnetic/mechanical design techniques in conjunction with several types of cooling techniques. After evaluation, two-phase fluid cooling using heat pipes was selected for development and an induction motor was built and tested at steady state power levels to 12.6 hp at 12,000 rpm. Heat pipes were used to increase the rate of heat removal in both the stator and the rotor. The heat pipes in the rotor acted as both electrical and thermal conductors while those in the stator were installed in the center of the stator slot to act as thermal conductors. (Author)
