[How To] Select a Motor Capacity for Agitator
And coming to Motor capacity, we have to consider approx. 30% excess to the required capacity, so the motor capacity will be 8.6 * 1.3 = 11.18 KW ~11.5 KW = 15.4 HP. ~16 HP. Usually a motor will have an RPM of ~1475, so to match the anchor RPM to 48, Gear box should have an ratio of 1475 / 48 = 30.75.

Torque calculation and Motor selection | Engineers Edge Forum | www
A 250 ton weighing system has to rotate in 1000 rpm using a geared motor. The calculation I used are as follows. To find power, I need to know the torque. 2 pi NT /60. To find torque (T), I used equations like. Method
The motors have enough torque and speed to do all kinds of experiments and calculations. Measuring the torque of the motor is a challenging task. It requires special expensive equipment. Therefore we suggest calculating it. Efficiency of the motor is calculated as mechanical output power divided by electrical input power: E = P out / P in
