Elliott was among the first to utilize magnetic bearings in critical service centrifugal compressors. Today Elliott compressors incorporate proprietary EDGE technology with advances in aerodynamics, rotor dynamics, computerized equipment selection, process simulation, and metallurgy, as well as custom-engineered lubrication, seal and piping. Heinz P. Bloch, Claire Soares, in Turboexpanders and Process Applications, Turboexpander Applications for Active Magnetic Bearings. Active magnetic bearings are certainly suitable for turboexpanders. These bearings are now being used in the aerospace and machine-tool industries, as well as in a variety of both light and heavy industries.
Compressor surge is a form of aerodynamic instability in axial compressors or centrifugal compressors. The term describes violent air flow oscillating in the axial direction of a compressor, which indicates the axial component of fluid velocity varies periodically and may even become negative. In early literature, the phenomenon of compressor. These oscillations can cause extensive damage to the compressor casing and internal components. In this thesis, we present an active surge control scheme that modulates the impeller axial position to stabilize the flow in active magnetic bearing (AMB) supported centrifugal compressors.
Yoon SY, Lin Z, Allaire PE. Control of surge in centrifugal compressors by active magnetic bearings: Theory and implementation. Springer Science & Business Media; Centrifugal, two-stage, magnetic-bearing chiller compressors equipped with variable-speed drives are a relatively new technology that operates at a high efficiency. Based on this case study, independent analysis by the U.S. Department of the Navy has verified that magnetic bearing compressors operate more efficiently than reciprocating and screw compressors, especially during partial load.

Meaning of Surge in a Centrifugal Compressor Ask a chemical or mechanical engineer, what does a compressor surge do, and he would shudder merely thinking of the consequences.
The centrifugal compressor is the heart of any oil & gas facility and since the last years has been subjected to scrutiny as to what is the perfect control mechanism.
Get this from a library. Control of surge in centrifugal compressors by active magnetic bearings: theory and implementation. [Se-yŏng Yun; Zongli Lin; Paul E Allaire]. • The focus of the control element is the use of a close coupled valve as a means of stabilising surge and rotating stall.
Little work has yet been published on this. Using techniques such as backstepping and passivity, controllers for a close coupled valve in the compression system are derived in order to stabilise the compressors and extend. Employing the active magnetic bearings (AMBs) of a compressor built for the experimental study of surge, the axial clearance between the impeller and the static shroud is servo controlled, and the measured variations in the compressor output flow are compared with the mathematical model.
Active magnetic bearings used on oil-free centrifugal refrigeration compressors have lower stiffness than conventional oil-lubricated journal or rolling element bearings. The lower stiffness of these bearings makes them sensitive to internal flow instabilities that are precursors of rotating stall or compressor surge.
At operating conditions far away from surge the internal flow is very stable. On the control of single stage centrifugal compressor surge with active magnetic bearings, in The 13th International Symposium on Magnetic Bearings (ISMB13).
Arlington, VA. Active control on surge in centrifugal compressors is a crucial case; AMBs have been widely used in such application that needs high dynamic performance. The bearingless motors are also shown promise as an effective means to produce both torque and magnetic levitation with a.

Control of surge in centrifugal compressors by active magnetic bearings theory and implementation /. magnetic bearings (AMBs) under several operating conditions. First, the working principle of the magnetic thrust bearing is introduced, and the tracking performance of the rotor under the low frequency is verified by experiments.
Then, the Greitzer model of centrifugal compressor is estab-lished. The variable speed centrifugal chiller compressors with active magnetic bearings save energy as compared to the conventional chillers by eliminating losses due to bearing friction and reduce maintenance costs.
