Abstract: A rotor bearing system radially supporting a rotor, held in magnetic suspension without contact, by active radial magnetic bearing phased arrays, bearing sensors used to measure the rotor motion and bearing properties, a controller system used to adjust variable magnetic bearing parameters via amplifiers for each array element in response to bearing sensors, to change bearing local array element stiffness and damping, generating bearing forces for levitating the rotor, stabilizing rotor vibrations, and acting as a rotor vibration actuator.
