N2 - The machining accuracy error makes the rotor inevitably have residual unbalance, which generates unbalanced vibration force through the magnetic bearing closed-loop control system. For magnetically suspended rotor system, the suppression accuracy of unbalanced vibration force largely depends on the accuracy of modeling of magnetic bearing closed-loop control system. Aiming at the problem of high-precision suppression of unbalanced vibration of magnetically suspended rotor system, this article carries out dynamic modeling of magnetically suspended rotor, combined with controller model and power amplifier model, and analyzes the motion characteristics of rotor system under the action of residual unbalance, so as to reveal the action law of rotor self-centering effect and unbalanced vibration force. Finally, the dynamic model and self-centering effect of the magnetically suspended rotor system built in this article are simulated and experimentally studied, which also lays a theoretical and model foundation for the subsequent realization of high-precision suppression of unbalanced vibration force.
