A compressor system including a driver machine, for example a motor or a turbine, an epicyclic gearbox, and a centrifugal compressor, wherein the driver machine, the epicyclic gearbox, and the centrifugal compressor are connected in train configuration, i.e. the output rotary member of the driver machine is coupled to the input rotary member of the epicyclic gearbox and the output rotary member of the epicyclic gearbox is coupled to the input rotary member of the centrifugal compressor. The gear ratio of the epicyclic gearbox is greater than one, typically much more than one, thus increasing the rotation speed from input to output. |
