    Abstract: The invention relates to a mounting for a turbo-machine rotor (16). Said mounting is characterized in that radial support of the rotor is assured by one or more permanent magnet bearings (20, 22). One or more single-thrust sliding bearings (24) provide axial support. The permanent magnet bearings (20, 22) also serve as a lifting device for the sliding surfaces of the hydrodynamic sliding bearings (24). A force (A), acting in the opposite direction from the axial force (B), is generated by axial displacement of the rotor-sided bearing elements (28) of the permanent magnet bearing (22), in relation to the housing-sided bearing elements (30), counter to the direction of axial force (B). This force (A) separates the sliding surfaces of the hydrodynamic sliding bearings (24) from each other in the stopping phases of the rotor. Once it has come to a stop, and when it is in the starting and stopping phases, the rotor is guided by one or more sliding or rolling bearings. These are so configured that, at low rotational speed and when at a standstill, they have a substantially lower moment of friction than the hydrodynamic sliding bearings used in the mounting.

    Abstract: A full levitation magnetic bearing system for support of a rotating body (71), such as a flywheel (92), about an axis of rotation includes passive radial magnetic bearings (70) that generate passive radial centering forces to counteract displacements of the rotating body (71) from its axis of rotation during rotation, and an axial actuator (102) for stabilizing the axial position of the rotating body (71). The passive radial magnetic bearings (70) include multiple concentric, radially spaced apart, axially magnetized ring magnets (73) on a stationary stator (72) and magnetically co-operating concentric pole rings (74) on a ferromagnetic end portion of a rotor (71). The rotor pole rings (74) are axially aligned with the magnet rings (73) when the rotor (71) is radially centered on the stator (72). Magnetic flux from the permanent magnet rings (73) passes directly across the airgap (78) between the axially facing surfaces of the magnet rings (73) and the rotor pole rings (74) and through rotating ferromagnetic section of the rotor (71), thereby generating both an axial attractive force and a passive radial centering force from the pole rings (74) tending to align with the stationary magnetized rings (73).
