Active Balancing of a High Speed Rotor in Magnetic Bearings - …

Abstract. This paper describes the appliion of an open loop control technique for the attenuation of unbalance response in a high speed rotor. The test rig is a mock up of a dual wheel compressor with an operating speed range of 30,000 to 70,000 rpm. The rotor has a third critical speed (first bending mode) at 24,050 rpm which is lightly damped.
