  • Torque Speed How Much Is Enough? | Plastics Technology

     · Highspeed, hightorque machines are often—but not always—one or two barrel sections longer than a conventional twinscrew. The highest screw speeds apply only to smaller screw diameters. WP's ZSK MegaCompounders go up to 1200 rpm but only in sizes up to 70mm diam. At 133mm, maximum speed is 1000 rpm.

  • Motor Selection Basics: Types of Electric Motors

    An AC induction motor will start from zero speed at torque "Ts", then gradually accelerate its speed past the unstable region, and settle on "P" in the stable region where the load and torque are balanced. Any changes to its load will cause the position of "P" to move along the curve, and the motor will stall if it operates in the unstable region.

    A 1 hp electric motor can raise 33,000lbs 1 foot in 1 minute. A 1hp gas engine can raise 33,000lbs 1 foot in 1 minute. They are equal in horsepower, but may require different gearing to do the task. Here is the part when other people join in to conflict physics. Horse power – you can't beat it.

  • Steppers as spindle motors

     · Most small mills and lathes use a DC motor or a VFD drive AC motor for the spindle. If you look at the torque and horsepower curves for those motors and drives the torque is fairly flat across the useable speed range. So at half speed you have the same torque, but that translates to half as much power too.

    Fig. : Rolling mill control From the above curves, we could understand the control of rolling mill. The solid curve, called plastic curve, represents the variation of rolling load with rolled thickness. As thickness reduces, roll force increases. This was shown earlier. The solid line represents the elastic deformation of the roll.

     · All you have to think about is the power rating and nominal voltage. If the voltage you apply is high (must be within the voltage range) then it can take less current and less torque which indeed can be found out from the speedtorque curve for a fixed voltage. Voltage is proportional to speed, and torque is proportional to the current.
