Driven Method of Extruders by Variable Speed Switched Reluctance Motor Drive (1)

Extruder, which is currently used, is driven by ordinary motor for screw rotation through the reducer. It is only to reach the volume of screw speed and extrusion by pressing the button down. When changing varieties and specifications of products, the adjustment of the volume of melt extrusion or extrusion rate is necessary to readjust the screw speed; when the head pressure begins to change, it is necessary to readjust the screw speed for restoring the pressure; and the auxiliary line likewise, it is necessary to readjust the screw speed.
