<p>The present invention provides a robust backup bearing for continuous operation of a rotor. The backup bearing is a magnetic bearing assembly (100) for supporting a rotor (102) adapted to rotate about an axis of rotation. The assembly comprises a plurality of active magnetic bearings (104, 106) positioned axially along the rotor (102) to provide radial support to the rotor (102). The assembly also comprises a plurality of permanent magnetic bearings (108, 110) positioned axially along the rotor (102) as backup bearing to provide radial support in case of a failure of one or more of the active magnetic bearings (104, 106).</p> |
