Motor Sizing Calculations

In order to determine the performance you'll need from the motor, there are three factors to calculate; Moment of Inertia, Torque and Speed. (Refer to the below sections on calculations for each.) Once you've calculated the inertia, torque and speed for the motor you'll select the type of motor based on the required specifications.

Chain Conveyor Speed Calculation | Physics Forums

Mar 22, 2017· CWatters. Looking at the conveyor sprocket. The PCD is 598mm so the circumference = Pi * 598 = 1878mm. (1rpm would move the belt at 1878mm/min which is too much, so we expect the required rpm to be <1rpm). The required velocity at the pitch diameter is 760mm/min so the required rpm of the conveyor sprocket is..
