Application of D71 Series In Screw Extruder System

Most screw extruders are generally driven by DC motors, but with the rapid development of power electronic devices and microprocessor technology, the proposal of AC control theory and the improvement of AC control software in recent years, AC drive technology is more suitable for many applications. DC drives are more cost-effective. D71 series inverters are used in screw extruders and have better speed control performance and torque response speed than DC drives.
