Automated Electric Drive for the Control System of a Two-Coordinate Welding Machine

A two-coordinate welding machine has been considered in this paper. Similar equipment is used to obtain welds on various elements of high-quality metal structures. The main disadvantage the existing that work with currently manual, which quite dangerous and monotonous during operation. Moreover, a hydraulic drive as system. Substitution an electric for increase efficiency whole system justified. An automated embedded parts, controlled use programmable logic controller, developed. object designed. necessary developed automation have selected. algorithm makes it possible automate process parts based technological process. provides security measures by means carrying out self-diagnostics at startup stage. To check performance algorithm, was simulated using Matlab Simulink software. contains two internal three external circuits control required parameters: speed, current, torque, flux linkage, force. dynamic characteristics presented parameters, confirm operability system, obtained. Economic calculations suggested implementation carried out. total cost modernization will be about 55 thousand rubles payback period one year.
