The screw of an extruder driven by switched reluctance motor can be operated through the gear of the motor, which can realize speed control under extrusion rate and the pressure. Generally, an extruder processes its own characteristics: wide range of speed adjustment, steady speed and high precision, small starting current, large starting torque. Due to a small heat-driven system, the occurrence of burning motor and controller is significantly reduced. In particular, it is very efficient to save energy, and the quantity of energy-saving is around 11%, compared with the variable frequency speed regulation system. Such an extruder has made a lot of progress: simple structure, digital control, stepless speed regulation, and high efficiency energy-saving.
