IN THE CANADIAN PATENT AND TRADEMARK OFFICE PATENT APPLICATION entitled : Method and device for reducing the vibrations of rotating machines equipped with an active magnetic suspension. Applicant : Société styled : SOCIETE EUROPEENNE DE PROPULSION In the names of : Helmut HABERMANN Maurice BRUNET André TASSEL ABSTRACT OF THE DISCLOSURE A device for reducing the vibrations of a rotating machine equipped with an active magnetic suspension comprises at least two vibration detectors located on the machine frame for detecting disturbances applied to the frame, and at least an additional selection feedback loop with narrow band and high gain whose central frequency is synchronized with a reference frequency and which receives signals delivered by the vibration detectors. The additional selective feedback loop compri- ses means for integrating the signals delivered by the vibration detectors and filtering means for eliminating the transient signals whose frequency is not linked to the reference frequency.
