Summary

THE ROTOR IS SUPPORTED BY HELIUM LUBRICATED GAS BEARINGS. A CONTROLLED ATTRACTIVE MAGNETIC BEARING IS ADOPTED AS AUXILIARY. THE SPECIFICATIONS OF THE COMPRESSOR ARE: TYPE: TWO-STAGES WITH INTERCOOLER ; FLOW RATE: 75 G/S ; TOTAL COMPRESSION RATIO EXCLUDING THE PRESSURE LOSS IN INTERCOOLER: 1.69 ; INLET HELIUM TEMPERATURE: 80 K ; ROTATIONAL SPEED: 700 RPS ; MOTOR OUTPUT: 10.2 KILOW. THE ROTOR SUPPORTED BY THE BEARING OPERATED STABLY UP TO 44,000 RPM. THE CONTROLLED ATTRACTIVE MAGNETIC BEARING GAVE AN ADEQUATE CLEARANCE TO THE THRUST GAS BEARING IN START AND STOP CONDITION, SO THAT THE ROTOR WAS ABLE TO START MANY TIMES WITHOUT ANY DAMAGE TO THE GAS BEARINGS.
