IN THE CANADIAN PATENT AND TRADEMARK OFFICE PATENT APPLICATION entitled : Device for compensating geometrical defects in the ring of a radial detector of the active magnetic suspension of a rotor. Maurice BRUNET Inventors: Michel LACOUR Applicant : SOCIETE EUROPEENNE DE PROPULSION ABSTRACT OF THE DISCLOSURE For compensating the geometrical defects of the annular armature of a radial position detector slaving an active radial magnetic bearing, a reference rotor having a small diameter is co-axially mounted within the rotor supporting the annular armature. The rotor supporting the annular armature and the reference rotor are both rotated in synchronism whilst a reference surface of the reference rotor is sensed by an additional radial position detector. A plurality of data representing the geometrical defects of the annular armature as a function of the angular position of the rotor are derived from the output of the additional radial position detector and stored in a memory to be applied to a compensation circuit linked with the radial position detector.
