Abstract

Motor failure determining system and the method, including a current detector for detection of the input current in the compressor-driven motor; a flow detector for determination of flow of the compressible fluid intaken into the compressor; a compression ratio detector for determination of ratio of compression; a reference value generator unit for generation of reference limit value for comparison of the methods of the detection of current by the current detector and the reference limit value for determination of existence of failure in the motor compressor system, and a failure determining unit which, when detecting existence of failure in the motor compression system with current of over the reference limit value, the reference limit value would increase along with increase of the current of increase of the compression ratio.
