Abstract: A landing bearing assembly for a rotary machine rotatable around a central axis and having a stator, a rotor with a shaft, a magnetic bearing, an auxiliary rolling bearing with two lateral faces, a landing sleeve facing, in normal operation of the rotary machine when the rotor is supported only by the magnetic bearing, the auxiliary rolling bearing at a nominal distance defined as the landing airgap El, the auxiliary rolling bearing coming into contact with the landing sleeve upon landing of the rotor in the event of a high shock. The assembly further provides a compliance ring with a nominal thickness Eo made from a material with a lower mechanical stiffness than the material constituting the other components of the landing bearing assembly to first absorb some energy of the shock by elastic deformation resulting in a reduction of its thickness.

Abstract: A radial magnetic bearing assembly having an unsymmetrical stator. The assembly comprises fewer or smaller electromagnets, and thus capacity, in the two lower quadrants below the rotor in use, in comparison to the electromagnets, and thus capacity, in the two upper quadrants above the rotor in use. This creates space in the two lower quadrants that can advantageously be used to move for example instrumentation and cooling from other places of the assembly to make the bearing assembly compactor, and also to be able to put instrumentation and cooling where it is best needed, close to the rotor.
