Abstract
A magnetic bearing arrangement for a rotor rotating in a stator comprises a first magnetic bearing with at least one permanent magnet on the stator or rotor cooperating with component parts on the rotor or stator respectively composed, at least partially, of ferromagnetic and/or permanent magnetic material, a second magnetic bearing with at least one actively controlled electromagnet on the stator cooperating with component parts on the rotor respectively composed at least partially of ferromagnetic and/or permanent magnetic material, and a sensor for sensing the axial position of the rotor and at least one damping circuit for damping oscillations in a radial direction or about axes perpendicular to the axis of rotation of the rotor, the two magnetic bearings having a substantially co-axial construction to provide passive stabilization in a radial direction.
