Horsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. = 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp. The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation.
The horsepower calculations for screw feeders require additional considerations. Please consult KWS Engineering for screw feeder applications. Horsepower is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft ...
full Motor Torque without failing . Every kwS screw conveyor is designed to this criteria with a minimum safety factor of 5 to 1 . The motor on the screw conveyor will stall out before there is a mechanical failure of a screw conveyor component . Maximum torque ratings for each screw conveyor component are shown in the Torque Tables .
Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45° incline or angles approaching this figure, are the most difficult on which to achieve successful conveying. Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material.
Screw conveyor horsepower requirements are directly defined in the CEMA Standard No. 350 – Screw Conveyor for Bulk Materials. To calculate the horsepower needs for a given application it is first important to understand the needs of the application. This includes the mass flow rate requirements in lbs/hr, the bulk density in lbs/ft3, the ...

Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.
Screw Conveyor Engineering Guide Horsepower Calculation. Total Shaft H.P. Calculation. TSHP = FHP + MHP* *Corrected if below 5 HP. Note: The actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor.
