In the previous studies, a driven method of extruders by variable speed switched reluctance motor drive is put forward. Based on analysis of present states of extruders, the method which could realize flexible numerical control by using variable speed switched reluctance motor to controlling the screw speed on velocity and pressure of extrusion was narrated. In addition, the advantage of saving energy and change of renovated extruders were analyzed. It was proved in practice that the renovated extruders had higher performances in efficiency and capability.
