ABSTRACT:
An electromagnetic bearing system for a movable (usually rotatable) member on a stationary member has bearing coils wound on a core for producing a magnetic field for supporting the movable member. High frequency sensor currents are applied to the bearing coils or to separate sensor coils on the same core or core portion as the bearing coils. The sensor currents produce signals responsive to deviation of the movable member from a desired position in which it is to be supported. These signals are amplified to provide bearing currents which are fed to the bearing coils.
