Abstract

A fluid compression system is disclosed having at least a compressor and a motor (or alternate driver) arranged within a hermetically-sealed housing. The motor rotates a shaft upon which the compressor is disposed, and the shaft is supported within the housing by first and second radial bearings arranged at first and second ends of the shaft, respectively. An intermediate radial bearing is also arranged on the rotatable shaft between the first and second radial bearings. The radial bearings can be active magnetic bearings and controlled by two sets of channels in a bearing control system in order to levitate and control the position of the shaft.
