Abstract
A device for detecting and correcting a radial oscillations of a rotor, particularly a rotor in a magnetic suspension, for the purposes of creating a restoring force to hold the rotor centrally of the stator, wherein several pairs of radial displacement detectors are coupled together and are relatively spaced such that the signals emanating from diametrically opposite detectors of each pair are cancelled out and the signals emanating from adjacent detectors of each pair are averaged to eliminate the effects of variations in the radius of the rotor.
