Active magnetic bearings

Active Magnetic Bearings (AMB) are usually meant as Active Magnetic Suspension applied to support rotor spindles. Without contacts AMB are the better tribologycal answer for very high spin speed rotors. Test Rig with spindle on Active Magnetic Bearings.

The absence of lubricants make them almost perfect for high purity vacuum application such as turbomolecular pumps. Modal testing of Turbomolecular Pump rotor on Active Magnetic Bearings. (Courtesy of Elettrorava S.p.A.)
