A hermetic reciprocating compressor for refrigerators and freezers, driven by a brushless-type electric motor and provided with a frequency control arrangement to let the motor run at any speed that is compatible with a correct operation of the compressor, achieving an increase in the overall efficiency, a reduction in the operating noise and a reduction in the energy consumption of the compressor. The new compressor design makes it possible to standardize and reduce the number of compressor models which are required to cover a broad application range in refrigeration appliances.
