ABSTRACT:
A fluid rotating apparatus includes a plurality of rotors accommodated in a housing, at least one of the rotors having its outer diameter different from that of the other of the rotors. Bearings are provided for supporting rotary shafts of the plurality of rotors. A fluid suction port and a fluid discharge port are formed in the housing. A motor is provides for rotating at least one of the plurality of rotors, and a control system for synchronously controlling the plurality of rotors in a contactless manner is provided for each rotary shaft of the plurality of rotors.
