This work proposes a comprehensive numerical dynamic model of a flexible-rotor bearing
system based on the Hertzian and cubic polynomial nonlinear contact force methods. The …

In electrodynamics, the levitation ensues when there is a relative motion between a stator
and a conductor owing to which high eddy currents are induced. The repulsive forces …

New technologies are being developed to elaborate cutting-edge electrical jet engines to
replace classical constructions. These new concepts consider the possibility of using …

Vibration analysis remains the most used technique for the maintenance of rotating
machines, despite requiring their availability. However, with the emergence of Industry 4.0 …

The paper considers passive magnetic bearings for small and medium-sized rotating rotors.
It proposes several schemes of a magnetic support made using two permanent annular …

To evaluate the important characteristics of electrodynamic bearings (EDB) finalizing electric
pole frequency (ω rl) is essential. This research article explores the evaluation of ω rl and …

Permanent magnetic bearings (PMBs) hold great potential for various applications such as
artificial heart pumps, space equipment, and flywheels. This is due to their notable …

A typically new semi-analytical finite element approach has been used to calculate the force
and moment of permanent magnet bearing (PMB) in this article. PMB stator and rotor consist …

The demand for low-loss and low-cost magnetic bearings is high. Currently, prevailed
reliable solutions for the magnetically supported rotor are active or partially passive (hybrid) …
