The steady state temperatures of a conventional, 15 HP electric motor were compared to those of a rotating-heat-pipe cooled motor under identical loading conditions. Fourteen thermocouples were used to measure temperatures at various
locations within the motor. Seven of these were placed in rotating parts of the motor and were recorded through a mercury slip ring unit. Tests were made with the electric motor in its original configuration (i.e. with a solid shaft),with its solid shaft replaced by a rotating heat pipe, and with this heat pipe unit containing segmented external fins
to increase air cooling. The modifications did not show a decrease of motor
temperatures. This was probably due to a lack of cooling air through the motor casing. Recommendations for future work are included.
