Abstract
Active radial magnetic bearing with solid rotor comprising a stator composed of an armature and electromagnetic coils, a rotor fast with a rotary shaft and placed opposite the stator, detectors for detecting the radial position of the rotor with respect to the stator, and servo-control circuits for adjusting the current going through the electromagnetic coils according to the value of the signals delivered by said position detectors. The electromagnetic coils are so designed as to create a rotating sinusoidal magnetic field with radial flux, the electromagnetic coils comprising a plurality of windings distributed over the periphery of the stator and supplied in succession one after another from the servo-control circuits. This type of bearing helps going through critical frequencies.
