摘要：气体静压电主轴由于高精度和高转速特性使其在硬脆材料磨削和单点金刚石切削中获得更多的应
用。为满足其高效加工的要求，需要使主轴在极高转速下快速制动，以减少换刀或工件更换时间；同时在断气情况下，主轴快速停止以防止刀具、工件和主轴自身损伤。提出了一种依据电动机转矩和制动时间的电阻能耗制动计算方法，并设计主轴控制和制动电气连接图。电气测试表明，所提出的方法可靠，可以有效地快速实现主轴制动，防止驱动器的电流过载报警。

Abstract : Aerostatic bearings have gained wide applications in the brittle material grinding and single diamond tur-
ing for its high speed and high accuracy characteristics. In order to satisfy the high efficient production demands, spindle needs to be braked from high rotational speed for the reduction of the tool exchange time. By the mean time, the fast braking could avoid tool collision and shaft damage. Calculation meth-od for the brake resistance was proposed according to the motor torque and braking time as well as the spindle control and brake electric connections. The electronic test indicated that the proposed method is reliable which could achieve spindle brake and prevent the current overload alarm.
Keywords : resistance dissipation; motor spindle; fast brake
