To maintain the stable operation of the wire drawing machine, there are many methods that can be used, among which the indirect way is to monitor the changes by detecting the voltage and current. Since any fluctuation will directly affect the control of the drawing machine system, the system can be controlled by changing the electrical of the drawing machine. In this case, an inverter is needed. By detecting the current on the DC side of the inverter of the wire drawing machine, the load change of the equipment can be fed back to find a certain control law. In the wire drawing machine, an AC frequency converter is used for speed regulation, so that the speed regulation progress can be improved and the process can be satisfied. Practice has proved that such a system not only helps the drawing quality, but also saves power to a certain extent. The operating efficiency of the equipment has also been significantly improved. This is how the energy saving of the drawing machine is achieved.
