Abstract
The present invention provides an active electric torsional vibration damper and a method to realize the same. The invention relates to the field of vibration reduction technology for rotating machinery. The damper comprises a fixed module, a relative rotating module, conducting coils, magnetic-field producing elements. The present invention can be used to produce transient anti-torsion which is same in frequency, opposite in direction and corresponding in amplitude to achieve the effect of eliminating torsional vibration on the original shaft system. The damper realizes a prominent effect of eliminating torsional vibration without complex measures.
