The Formula. There is a reliable formula for working out the speed of your belt, and it looks like this: · Speed = roller circumference x motor RPM (revolutions per minute) However, if you have a gear reduction system in place, you'll need to factor this into the equation. For example, if your gear ratio is 20:1, you'll need to divide the ...
