Torque effective load rate - if torque is too big choose bigger ratio. Maximum speed - bigger gearbox ratio means bigger motor speed. Please try not to exceed nominal speed of the motor because torque characteristic drops then. Maximum load inertia moment - load inertia is reduced in square by gearbox ratio.

The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on.

When the ball mill load is low, the motor can be put into 3, 2, or 1 module for operation, and the torque distributed equally to each module is 4/3, 1.5, or 4 times that of the original. Obviously, the efficiency will be increased when the number of operating modules at low load (torques at the same speed) is reduced.

When pulleys, belts, gears, sprockets, chains, etc. are used as the transmission mechanism, the dynamic radial load is calculated with the following equation. W = T / y. With a belt conveyor, the motor torque provides the driving force that generates work. This is shown as T, which is the amount of torque in N·m.

J D = inertia of drive (ball screw, belt, rack & pinion) J E = inertia of external (moved) load. J C = inertia of coupling. J G = inertia of gear set or gearbox. i = gear ratio. Note that the inertia of the gear set or gearbox (J G) is added to the load inertia, but its effect is typically small compared to the reduction provided by the gear ratio.
