He holds 21 authorized invention patents.

## **Preface to "Selected Papers from the 16th International Symposium on Magnetic Bearings (ISMB16)"**

Magnetic bearing is an electromagnetic device that provides magnetic force in order to suspend shafts, in contrast to other conventional bearings which rely on mechanical force. With the inherent distinguished features including the absence of mechanical wear, the elimination of lubrication, long life expectation, tunable stiffness and damping, as well as high attainable rotating speeds, magnetic bearings are widely applied in compressors, bearingless motors, and other high-speed rotating machinery applications. The fast and continued expansion of magnetic bearings has trigged enormous interest in both academia and industry. In 2018, the 16th International Symposium on Magnetic Bearings (ISMB16) was held in Beijing, China. In this symposium, six plenary speeches and 112 selected papers were presented. Herein, eight distinguished papers were selected to be published as Special Issues. These papers are suggested to provide new insights for the development of magnetic bearings, with emphasis on thermal behavior analysis, electrodynamic thrust bearings analysis, viscoelastic damping design, magnetic spring, condition monitoring, self-bearing motors performance.
