Abstract :
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 time which causes onset of system instability. Numerical simulation results of time delay effects on Single-DOF AMB system are presented in detail.
