Vibrations controlling apparatus of rotating machines with active magnetic bearings

摘要

The vibration control device for a rotating machine using an active magnetic bearing according to an embodiment of the present invention includes a rigid body rotating body, an electromagnetic bearing connected to a rotating shaft of the rigid body body, and an electromagnetic bearing, which is used for mass imbalance of the rigid body rotating body. The stiffness value and the damping value of the electromagnetic bearing can be controlled, and the mass imbalance of the rigid body rotating body can be controlled to generate a response vector and a sensor unit measuring a response vector that applies a load of an opposite phase to the external force vector. In addition, the vibration control device of the rotating machine by the active magnetic bearing as described above may be implemented in various ways according to the embodiment.
