ABSTRACT:
A radial active magnetic bearing for supporting a rotary shaft in a casing is provided with at least one back-up bearing constituted by a first ring fast with the rotary shaft and a second ring fast with the casing, the rings being concentric and defining a free space whose length in the radial direction is about one half the length of the mean air gap of the radial magnetic bearing. The first and second rings are preferable anchored, respectively, in the stator laminated ferromagnetic rotor armature and in the stator laminated ferromagnetic stator core of the radial active magnetic bearing which may also provide hydrodynamic effects by pumping fluid into the air gap of the bearing.
