摘　　要：随着电机调速与伺服控制方式、电机技术等的飞速发展,交流伺服直驱控制技术得到广泛应用。本文分析了目前直线电机直接驱动式、伺服电机直接与曲柄相连式、伺服电机通过减速器与曲柄肘杆等机构相连式、双伺服电机驱动丝杠螺母机构4种不同的交流伺服直驱传动方式的工作原理、输出特性以及用于回转头压力机中的优缺点。获得了交流伺服电机的转速、最大扭矩、当量负载扭矩、连续过载时间等主要技术参数选取的合理方式,并建立了相应的计算公式。The working principle, output characteristics and merits ＆ demerits of application in CNC turret punch press of the four AC servo direct driving modes have been analyzed in the text, which includes linear motor direct driving system, servo motor directly connecting with crank system, servo motor connecting with crank knuckle via speed reducer system, and dual servo motor driving screw nut mechanism system. The proper selection mode of main technical specifications including rotation speed, maximum torque, equivalent load torque, and continuous overloading time of servo motor has been obtained. The related calculating formula has been established.
