Jan 06, 2016· LOAD REQUIREMENTS – TORQUE–SPEED CHARACTERISTICS The most important things we need to know about the load are the steady-state torque–speed characteristic, and the effective inertia as seen by the motor. In addition, we clearly need to know what perform- ance is required. At one extreme, for example, in a steel-rolling mill, it may be necessary.

Mar 23, 2012· We ahve obtained the motor characteristic curves with associated inertia. However, we only managed to obtain the pump inertia and rated torque. We have requested our Mechanical team for the pump speed vs. torque but all they have instead is a pump performance curve that indicates the head and associated flow rates in gallons per minute.
One example is the large ball mill used in minerals processing. Rotating at 15 to 30 RPM, the mill drum contains a mass or "charge" of material tending to become compacted in the bottom of the drum at standstill. Motor speed is typically 400 to 514 RPM. As mill rotation commences, the charge is lifted through an angle, requiring high motor ...

Jun 14, 2019· A servo motor's torque-speed curve includes two operating zones: continuous duty and intermittent duty. To choose a motor that can meet the application requirements, it's important to ensure the application runs within the continuous duty zone during normal operation and does not exceed the intermittent duty zone when peak torque is required.
ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve. The initial torque to start rotation will most likely be over or rated torque. How much depends on the design of the mill.
