Magnetic actuator control of oil whip instability in bearings

Magnetic actuators are successfully used in the control of the rotating machinery by using its feedback to eliminate the undesired vibration. Control algorithms could be implemented through the magnetic forces applied using the magnetic actuator which could be controlled through the current induced in the coils. A novel bearing is introduced integrating the journal bearing ability to carry high loading conditions and the magnetic actuator active control action. This enables the increase of the speed reached by the rotors by avoiding the journal bearing oil instability by implementing active control actions using the magnetic actuator force.
