摘要
介绍了一种新型CO2弧焊送丝调速系统。该系统采用PWM脉宽调速,通过光电测速进行速度反馈调节,结构简单,控制精度高,动态响应快,值得推广。
A new wire-feed system is introduced in this paper.The system regulates wire-feed speed by PWM and photoelectric measuring speed circuit is used for negative feedback of speed control.This system has characteristics of simple configuration,high accuracy and fast dynamic response,which is worth spreading and applying.
