摘　　要：目前在塔机起升电机中已经开始采用变频器进行控制,它具有速度的平滑过渡,对机构和结构件无冲击,提高了塔机的运行安全性,同时又能进行节能。本文介绍了A700变频器在塔机起升电机中实施控制并解决了制动问题,达到并超越了原先的控制性能。The frequency inverter has been used for the tower crane hoisting motor. It has a smooth transition of the speed, without the impact on the structures. And it improves the operating safety of the tower crane, as well as the energy-saving. This paper describes the brake control of A700 in the hoisting motor which has exceeded the original control performance.
