<p>The invention relates to an active magnetic suspension device of a rotor placed in a sealed enclosure. Each active radial bearing comprises a stator composed of electromagnetic windings associated with a magnetic yoke which has end pole pieces placed at a short distance from the annular armature mounted on the rotor, the electromagnetic windings being arranged outside the sealed enclosure. Each stator magnetic yoke of luminary material is extended at the level of the end pole pieces by a terminal portion of non-laminar material, of small thickness, which constitutes directly a portion of the wall of the sealed enclosure and is attached by welding to the non-magnetic sealed wall portions which are not situated facing the annular armature.</p> |
