摘要：
Mass imbalance is a typical cause to failure of machine tool spindles. Because the active balancing system can automatically reduce the unbalance vibration of spindle rotors, it is an essential component of intelligent machine tool spindles. A novel electromagnetic-ring balancing actuator was introduced in this study, which can be integrated into hollow rotors of spindles and compensate the initial mass imbalance through step rotation of two counterweight discs driven by magnetic field. The effectiveness of the balancing system was verified by an active balancing experiment. The experimental results show that the active balancing system could reduce the unbalance vibration of the machine tool spindle by 87.5% at 3 600 r/min. © 2019, Editorial Office of Journal of Vibration and Shock.
