Beschreibung
Zusammenfassung:	The invention discloses a three-motor driven single-screw compressor. The three-motor driven single-screw compressor comprises a screw arranged in a machine shell and two star wheels symmetrically arranged on the two sides of the screw. The screw and the two star wheels are independently connected with three motors through couplers, the three motors are connected with a power source, and the rotating speeds of the motors can be controlled through a frequency converter. The frequency converter is provided with a controller, the rotating speed ratio is set in the controller, and the set frequency is set in the frequency converter. The screw and the star wheels rotate synchronously and do not make contact with one another, and a sealed air cavity is formed by a screw groove of the screw, theinner wall of the machine shell and teeth of the star wheels. The machine shell is provided with a gas inlet and a gas outlet, gas enters the screw groove from the gas inlet through a gas suction cavity, when the teeth of the
