【Abstract】 High stiffness and high speed are both important proporties in active magnetic bearings (AMBs) grinding electrospindle system. Theoretical analysis, computer simulations and experiments were used to analyze the effect of the power amplifier current response rate and the electromagnetic force response rate on the performance of the magnetic bearing system. The results show that both response rates directly affect the performance of the closed loop system. A stable rotation speed of 46.320kr/min and a stiffness of 39.3N/μm were obtained with increased power amplifier current response and electromagnetic force response rates.
