| Abstract: | Traditional electro-excavator control systems have some disadvantages such as dated technology,high failure,low efficiency,high run cost and so on,thus a digital control DC speed regulating device is designed and developed for electro-excavator.In this study,small power CT-M75R digital driver was used to drive 12p large power SCR which construct full-wave bridge main circuit of the DC speed regulating device,furthermore voltage feedback and current feedback are connected with CT-M75 driver in the control circuit,and synthetic feedback control combined voltage with current is realized by means of CT-M75 software function.Compared with other DC speed regulating devices for electro-excavator,this device provides low price,excellent speed regulating performance,convenient maintenance and prominent energy economizing. |
