Motor Sizing Basics Part 1: How to Calculate Load Torque
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...

Feeding the facts: Proper sizing and selection of your apron feeder
Apron feeders are a volumetric type feeder, which means bulk density is used to determine the speed and power (torque) needed to extract a certain tonnage per hour (tph) of material. The minimum bulk density is used to determine the speed and the maximum bulk density establishes the power (torque) needed for the feeder.
