Seven, summary
The system consisting of domestic rare earth permanent magnet servo motor has the advantages of diversified control modes, high control precision, obvious energy saving effect, stable operation, etc. It is close to the international advanced level, and the after-sales service is more comprehensive and fast, saving users money. At present, TYSZ rare earth permanent magnet AC servo motor has been widely used in metallurgy, printing and dyeing, packaging, textile, printing, military and other industries, and its use is good. With the continuous expansion of application fields and application industries, domestic rare earth permanent magnet servo motors are also constantly maturing and constantly improving.
The successful application of rare earth permanent magnet AC servo motor and its drive system in the continuous casting production line shows that the domestic rare earth permanent magnet servo motor (especially the high power servo motor) is matched with the high performance servo controller, and the system is fully satisfied. Certain high performance process requirements are a cost effective system solution.
