Abstract
A contactless magnetic bearing system comprises a passive axial bearing element which serves to exert axial stabilizing forces on the rotor and at the same time exerts radial destablizing forces thereon, a controlled or active radial bearing element for counteracting these radial destabilizing forces and a passive radial bearing element which supports and journals the rotor at a position axially spaced from the two first-mentioned bearing elements. The axial destabilizing forces produced by the passive radial bearing are counteracted by the much stronger axial forces exerted by the passive axial bearing element.
