Active magnetic bearings (AMBs) have various advantages over traditional bearings. Backup bearings are an essential part of AMB because they support the rotor while it is not operating and they prevent rotor-stator contact if failure occurs in the AMB. To investigate backup bearing behavior during rotor dropdown events a test rig without actual AMBs was built. Measurements with the test rig have strong correlation with the measurements of actual magnetic bearing system. This proves that the test rig with the pneumatic dropdown system is valid for backup bearing tests.
