Reduction of rotor vibration is very important for safe and efficient functioning of all rotating machines. Active vibration control methods for rotors were studied in order to enhance machine's dynamic behavior, durability, and operating range. This paper proposes two different active vibration control schemes for controlling transverse rotor vibr...

... Multi-harmonic vibrations induced by the imbalance, misalignment and load-torque effects at multiple operating speeds were suppressed in an AMB controlled driveline system. In [123,124] it was observed that by incorporating stiffness and damping effects, electromagnetic exciters help to reduce unbalance response amplitude and simultaneously raise stability limit speed of the rotor-shaft system. It was also found that there exist specific locations of the exciters along the shaft length that provide substantial reduction of response and increment of stability limit speed with relatively low value of control current. ...
In this paper a critical review of literature on applications of Active Magnetic Bearings (AMBs) systems in flexible rotordynamic systems have been presented. AMBs find various applications in rotating machinery; however, this paper mainly focuses on works in vibration suppression and associated with the condition monitoring using AMBs. It briefly introduces reader to the AMB working principle, provides details of various hardware components of a typical rotor-AMB test rig, and presents a background of traditional methods of vibration suppression in flexible rotors and the condition monitoring. It then moves on to summarize the basic features of AMB integrated flexible rotor test rigs available in literature with necessary instrumentation and its main objectives. A couple of lookup tables provide summary of important information of test rigs in papers within the scope of this article. Finally, future directions in AMB research within the paper’s scope have been suggested.
