In this paper, the structure, working principle and application scenarios of the ball screw lift are introduced, and the design and implementation of its motion control system are analyzed in detail. Through the analysis of the working characteristics of the ball screw and the dynamic model, a motion control algorithm based on PID controller is proposed to achieve precise control and stable operation of the lift. At the same time, in order to improve the safety and reliability of the lift, a complete set of safety protection system is designed, including over-limit protection, emergency stop protection, power failure protection and other measures. The experimental results show that the designed motion control system of the ball screw lift has good performance and stability, and can meet the requirements of a wide range of applications. Keywords: ball screw lift; motion control; PID controller; safety protection,其误差范围为±30μm/300mm,因此，在实际应用中需要综合考虑各种因素进行计算, 3. 用螺丝刀将支架与底座固定，确保支架不会移动,例如，在飞行控制系统中，滚珠丝杠用于控制飞机的姿态和位置，以确保飞行的稳定性和安全性,同时，该机床配备了先进的数控系统，能够实现自动化加工，并且具有操作简便、稳定可靠的特点,螺旋角指的是螺旋线与轴线之间的夹角，计算公式如下： 螺旋角 = arctan（πd*cosα/p） 其中，d为螺纹直径，α为螺旋线倾角，p为螺距, 3. 通过旋转一个零件或两个零件来启动滚珠丝杠螺母，使其顶部滑动，从而使两个零件连接在一起, 3. 转速要求：要根据应用需要选择合适的转速范围，以确保滚珠丝杠能够正常运转, 2. 用手柄或钥匙旋转珠子时要小心，避免过度旋转导致珠子损坏
