The system comprises a rotor of an electric motor inside which such an inner cylinder is coaxially arranged and a cylindrical stator (63) is fitted onto said rotor, in such a way making an electric motor in which the rotor is hollow and cylindrical and a propeller is arranged inside it that rotates with said rotor.
