tailieunhanh - Magnetic Bearings, Theory and Applications

The term magnetic bearing refers to devices that provide stable suspension of a rotor. Because of the contact-less motion of the rotor, magnetic bearings offer many advantages for various applications. Commercial applications include compressors, centrifuges, high-speed turbines, energy-storage flywheels, high-precision machine tools, etc. Magnetic bearings are a typical mechatronic product. Thus, a great deal of knowledge is necessary for its design, construction and operation. This book is a collection of writings on magnetic bearings, presented in fragments and divided into six chapters | Magnetic Bearings Theory and Applications edited by Bostjan Polajzer SCIYO Magnetic Bearings Theory and Applications Edited by Bostjan Polajzer Published by Sciyo Janeza Trdine 9 51000 Rijeka Croatia Copyright 2010 Sciyo All chapters are Open Access articles distributed under the Creative Commons Non Commercial Share Alike Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
