The mounting errors of displacement sensors, the influence of rotor weight and processing quality will make the working position relative to the reference location center of the rotor shift for the magnetic bearings. In different equilibrium positions have different stiffness, so the stiffness namely variable stiffness changes with the actual work situation for the magnetic bearings. In the paper,...
Active Magnetic Bearing (AMB) system has been used in higher rotating speed and higher precision rotor system, the influence of time-delay can't be neglected. The focus of this paper is presents the influence and demonstration of the system time delay effects on AMB system that has been usually disregarded. Then, we present both explicit formulas and numerical solutions to determine the maximum delay...
