Abstract:

一种送丝调速装置,其属于焊接技术领域,其将交流电变化为直流电整流器连接到电机电路的两端;同步电路的一端接到PWM芯片的管脚a上,另一端连接到采样保持电路,采样保持电路的输入端与电机电路相连。电流保护电路的输入端与电机电路相连。采样保持电路和电流保护电路的输出端连接到比例积分电路,比例积分电路的输出端与PWM芯片的管脚b相连;PWM芯片的管脚c与开关管相连,控制开关管的导通与关断。本实用新型通过对电机工作于发电机状态时感应电动势的信号采集,可以比较精确地反映出电机旋转的速度,从而精确控制其转速,达到送丝速度稳定的效果。同时此种方法通过闭环反馈控制电机的转速,结构简单,成本低廉,精度较高。
