I believe this motor will work okay to power my bead roller. It's still mounted on the frame of the machine, and has the controler on it. I don't know exactly what the machine was, but it wasn't a treadmill. The shaft is 7/8, and at full speed turns at just under 24 rpm. Now I'm not real good at math, but I think that would give me just under 67 inches a minute at top speed. Sound right? So do I need to implement sprockets and chain, or could I just couple it straight to the shaft with a lovejoy coupling? Also, can this motor be made to reverse, and if so how? I'm thinking for starting and stopping, a simple on/off foot control would work.
