ABSTRACT:
A magnetic bearing arrangement for a rotor, having permanent magnets to absorb radial bearing forces, and having an axial stabilizer which keeps the rotor in a contactless position in relation to the stator. Attached to the stator are electric coils, which interact with magnetizable parts fastened to the rotor. To make the bearing arrangement as independent as possible from the spatial orientation of the rotor axis, and from housing deformations, there is provided, in the vicinity of the rotor center of gravity, a center-of-gravity bearing having a comparatively high radial rigidity and at another point of the rotor there is provided a stabilizer bearing, having a radial rigidity which is less than that of the center-of-gravity bearing. The center-of-gravity bearing supports the major portion of the rotor weight, and the stabilizer bearing is primarily responsible for the static and dynamic stabilization of the entire system.
