I used a gear motor to motorize my MM3 3 roller mill. It has 40 in/lbs of torque. Not enough. Kept jamming and I've come to find out that this mill requires at least 50-60 in/lbs of torque.
So I'm looking to see if another motor will work. Does anyone know if I'm doing this correctly?
I dug around the garage and found I have a 1/4hp blower motor. I tried to calculate the torque using this formula.
T = (5252 * HP) / RPM
T= (5252 * .25) / 173
If I reduce the RPMs to 173 with a gear box I get 7.59 foot/lbs of torque.
Multiply by 12 and I get 91 In/lbs of torque.
Is this correct?
I'm concerned because it seems like a lot of people suggest you just go for a 1/3HP to 1/2 HP motor. But 91 In/lbs would seem to be good enough, no?
Thanks for the help. As usual, I only find the right threads on here after I make a purchase and then have issues to use as search terms. Gotta laugh.
Cheers.
