本文对作者提出的采用主动空气动力轴承的高速气浮机床主轴进行了跟踪研究。在气浮主轴中采用同步电动机代替传统的感应电动机，以提高主轴的旋转精度。通过控制气动轴承的楔角，可以抑制主轴振动。由于采用同步电机，在500 Hz（30, 000 min）的转速下，主轴振动的振幅可以被抑制到0.05m。
A follow-up report of the high-speed air-bearing tool spindle with an active aerodynamic bearing proposed by the authors is presented. Instead of the conventional induction motor, a synchronous motor is built in the air-bearing spindle for improving the rotational accuracy of the spindle. By controlling the wedge angle of the aerodynamic bearing, the spindle vibration can be suppressed. Owing to the adoption of the synchronous motor, the amplitude of the spindle vibration can be suppressed to be 0.05 m at the rotational speed of 500Hz (30,000min).
