<p>A motorized compressor comprises a compressor component 20, and a drive component 10, 11 coupled together with a unitary, one-piece transmission component 10A, preferably a drive shaft. The drive component 10, 11 is typically a hydraulically, electrically or pneumatically driven motor, which, by means of said transmission component 10A, rotationally drives the compressor component 20. All the components are integrated within a common pressure housing which includes an entry port and exit port by means of which the fluid to be compressed enters and exits said housing. The compressor is characterized in that the compressor component 20, drive component 10, 11 and said transmission component 10A are rotatably mounted in three magnetic bearings 2, 6, a pair of said bearings 6 being disposed at remote ends of said transmission component 10A, and a third bearing 2 being disposed between said drive component 10, 11 and said compressor 20 component, the stator 14 of the third bearing 2 being split so as to enable easier assembly of the compressor unit. A pair of auxiliary bearings 9 may be provided at each end of the shaft 10A, and a there may be provided a single primary thrust bearing 8.</p> |
