A case study of an electric motor with Active Magnetic Bearings (AMBs) that is subjected to the waving of the supporting foundation is presented. The motor is intended for sea applications where the ship is disturbed by the oscillation of the waves. Initially, a tilt-and-translate PID controller is designed to stabilize the rotor in the magnetic bearing(More)
Squeeze film dampers are widely used in aircraft engines, land-based gas turbines, and other rotating machines to improve system damping. They often have entrained air within the oil film, which is usually not taken into account in rotordynamics analysis due to lack of good formulations of the effects involved. The effects on the damping force calculation(More)
