Abstract
A torque control apparatus for enclosed compressors wherein a load torque, applied to an enclosed compressor, is detected by a position detector provided on the rotating portion of the compressor and a temperature detector provided in a refrigeration cycle. A voltage or current supplied to the compressor is controlled in accordance with the load torque to control the motor output torque of the compressor.
