ABSTRACT:
The present invention relates to a system employing an active magnetic bearing for controlling and isolating rotor vibrations. The invention includes an active magnetic bearing having a stator, an armature and an inner bearing located within the central bore of the armature. The active magnetic bearing has dynamic stiffness sufficiently low with respect to the inner bearing so that the inner bearing tracks shaft motion in an oscillatory manner while magnetically suspended during flotation of the active magnetic bearing. The inner bearing can be either a fluid film bearing or a rolling element bearing. The system allows for continued operation in the event of failure of the active magnetic bearing.
