Sizing A Motor & Drive System | Control Techniques
Motor-Drive sizing. To effectively size the motor, it is necessary to calculate the load inertia (JL). The ratio of load inertia to motor inertia (essentially, rotor inertia) gives a measure of how effectively the motor can control the load. A high inertia ratio indicates the system that will have difficulty controlling the load.

Sizing A Motor & Drive System. Proper sizing is a crucial aspect of motor selection. If a motor is undersized, it will not be able to control the load, leading to overshoot and ringing. Over-sizing a system …
How to calculate motor drive torque for belt and pulley …
For a belt drive system, the motor torque required during constant velocity is simply the total axial force (F a) on the belt multiplied by the radius (r 1) of the drive pulley. Tc = torque required during constant velocity (Nm) Fa = total axial force (N) r1 = radius of drive pulley (mm) η = efficiency of belt drive system.
