Abstract
A new concept of active dynamic stabilizer aimed to operate the rotors at fairly high supercritical speed is here investigated. Instead of using the non rotating damping, as the classic literature suggest, a contra-rotating action is applied. Experiments were performed first on a flexible rotor, successfully stabilized by an eddy current magnetic damper. Advantages of contra-rotating the control forces of the active magnetic bearings of an electromechanical spindle are then described.
