This research was conducted in order to better identify the torque loss of a hermetic rotary compressor for one revolution, and to directly obtain the actual shaft power of the compressor. Torque of the compressor was measured for one revolution by attaching a strain gauge to the part of the rotary compressor crank shaft where the compressor was connected with the motor. The torque loss was obtained from the difference between this torque and the effective compressive torque required to compress a discharge of refrigerant gas. Loss due to over-compression was identified from this torque loss. Moreover, the actual shaft power gained by the compressor and motor output were compared.
