ABSTRACT:
A rotating machine having a rotor comprising a flexible shaft with a plurality of masses distributed along the shaft. Included within these masses are magnetic disks. Magnetic bearings are attached to the housing and coact to support the rotor in only a radial direction or in both radial and axial directions. Bearing sensors are used to measure the shaft position local to each bearing relative to a face of each bearing. Variable magnetic bearing parameters are controlled so as to change values of stiffness and damping of the magnetic bearings in response to the measurements from the bearing sensors. These controls can be direct analog circuitry, or digital components, or a combination of digital and analog components.
