S = Conveyor Speed. Torque is measured in inch-lbs. for screw conveyor components. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be able to withstand Full Motor Torque without failing. Every KWS screw conveyor is designed to this criteria with a minimum safety factor of 5 to 1.

Required Power = 140 lbs x 50 fpm = 7,000 ft-lbs/min. Convert that to a useful unit of measure. One horsepower (HP) equals 33,000 ft-lbs/min. Therefore, our power requirement can be converted as follows. Required Power = (7,000 ft-lbs/min)/(33,000 ft-lbs/min per HP) Required Power = 0.2 HP. Now we can select an appropriate conveyor drive system.
