Topic: Re: What is the torque required for speed reducer and what horsepower is required to run it smoothly?

The calculation for torque from power and rotational speed is merely a matter of a conversion factor.  Torque (inch-lbs) is 63,025 times the power (hp) divided by rotational speed (rpm).     63,025 x 3 / 60 = 3,150 inch-lbs or 263 ft-lbs.
