Abstract
A magnetic bearing rotating structure includes a rotor magnetically supported in a housing by a magnetic bearing. A back-up bearing arrangement is used to resist impact on the rotor, including a fixed bumper bearing for resisting a sudden impact, and an auxiliary bearing for rotatably supporting the rotor while the magnetic bearing resumes operation.
