Active magnetic bearings (AMB), controller, back up bearings

Design of magnetic bearing controllers
Analysis of the rotordynamic stability in closed loop condition of the magnetic bearing controller including all relevant effects such as rotor fluid interaction
Rotordynamic response analyses to unbalance and transient forces in closed loop condition of the magnetic bearing controllers
Assessment of the magnetic bearing capacity considering all relevant dynamic and static forces
Transient analyses of rotor drops into back up bearings in order to specify and assess the auxiliary bearing design, especially the stability against whirling

High speed spindle supported on magnetic bearings running at a maximum speed of 120'000 rpm
