Multi-DOF rotor model based measurement of stiffness and damping for active magnetic bearing using multi-frequency excitation
Comparing AMB with traditional mechanical bearing. Parameters identification for AMB supporting. Multi-DOF rotor model based measurement. Lowest peak value of multi-frequency signal superposition. Avoid great rotor vibration and magnetic force saturation.
