摘　　要：在较大设备的交流拖动频繁启、制动控制工艺中 ,如何迅速可靠停车是一个重要问题。利用检测电机转子频率的方法控制无触点系统实现了 45 0t冷剪机的反接制动稳定停车 ,方法简单 ,运行可靠。It is an important task to rapidly and reliably stop an alternating current transmission that starts and stops frequently.The reverse-control wired stable stop of a 450 t cool-shear-machine by measuring the electromotor rotor frequency to control the non-contact system is succeeded.This simple method is reliable.The principle of this control system and our experience of test are introduced.

关 键 词：转子频率 反接制动 450t冷剪机 可靠停车
