Abstract
A magnetic bearing for centering and controlling tilting of a first body relative to a second body includes centering members adapted to center the first body magnetically relative to the second body at least in the direction transverse to the reference axis, two permanently magnetized rings carried by a first ferromagnetic armature fastened to the first body, an annular plurality of (at least three) tilt windings fastened to the second body and each including two groups of circumferential strands respectively adapted to face each of the permanently magnetized rings regardless of the orientation of the hollow outer part, and an excitation circuit adapted to apply excitation currents to the tilt windings adapted to generate tilting forces in the air-gaps.
