摘　　要：连轧管机组需要70多台电机协同工作,开发一种能确保电机稳定运行的电控系统十分必要。电机的温度、电流、震动是电机性能和性能的变化的重要特征体现,这就需要寻找一种可靠的温度、电流、震动信息采集方案;有效比对采集后的温度、震动信息能实现电机性能的预测,电机电流限幅作为拖动设备的极限值保护。通过投入以上手段能够减少连轧管机组电机的故障率和提升整个机组的作业率。More than 70 motors are required for the continuous rolling mill unit to work together.It is necessary to develop an electronic control system that can ensure the stable operation of the motor.The temperature,current,and vibration of the motor are important characteristics of the performance and change of the motor.This requires finding a reliable solution for collecting temperature,current,and vibration information;effectively compare the collected temperature and vibration information to realize the prediction of the motor performance,and the motor current limit is used as the limit value protection of the dragging device.The investment through the above means can reduce the failure rate of the motor of the continuous rolling mill unit and improve the operation rate of the entire unit.
