dc.description.abstract	This paper presents the experience of the authors with a turboexpander (TEX) equipped with active magnetic bearings (AMBs) in a natural gas processing facility. The TEX was unable to achieve design performance due to high sub-synchronous vibration since its commissioning. Rotordynamic simulations revealed that the most likely root-cause of the high vibration was the excitation of an unstable rigid body mode of the rotor-bearing system due to high cross-coupled stiffness effects. This paper also contains a summary of the redesign features incorporated in the TEX that resolved the sub-synchronous vibration.	en
