A drive on an extruder screw is essentially

  • A.a load whose torque falls with the square of the speed
  • B.a load requiring no torque at all below base speed
  • C.a constant-torque load with a wide speed range
  • D.a constant-power load requiring field weakening

Answer: C

The pressure the screw must develop is set by the die and the material rather than by the speed, so the torque is nearly flat and the power rises with output. Constant flux over the whole range is therefore what the drive needs.
