A screw feeder is commonly used to meter flow in powder processing applications because of ease of use low maintenance and material integrity without degradation The relatively simplistic equipment design of the screw feeder can be misleading when selecting and specifying motor and auger sizIn our example input electrical power of the motor is 022 A x 6 V = 132 W output mechanical power is rpm x 2 x 314 x N•m /60 = W Motor torque changes with the speed At no load you have maximum speed and zero torque
