A centrifugal compressor assembly, especially one having two or more stages, has a first compressor casing having a fluid inlet and a fluid outlet and a first impeller rotatable within the first compressor casing. A second compressor casing provided having a fluid inlet and a fluid outlet and a second impeller rotatable within the second compressor casing. Drive for the compressors is provided by a switched reluctance motor disposed between the first and second compressor casings and comprising a stator and a rotor rotatable within the stator. A drive shaft is provided, wherein the first impeller, second impeller and the rotor are mounted on the drive shaft and rotatable therewith.
