Re: Pitching Machine Motor Calculations

You have to remember that rpm or 20,000 is free speed. Once you put a load on it you will lose some speed. Also depending on what wheels you use, assuming a ball launcher using wheels, you may want a different out put speed. And like I said a 4 to 1 provided enough torque to spin up two 8" wheels.
