As far as the torque the conversion from 90 N*m to ft lbs it's approximately 66 ft.lbs.
I assume that should be sufficient for a MM3?
After looking at the Hoppopotomus set-up I'm embarrassed to show the rest of mine. That's the stuff I dream about. Great job!
Anyway, here's my project ready to do some work. Made the coupling for between the gearmotor and mill. Had to change the electric enclosure to a Radio Shack project box. The large capacitor wouldn't fit in the small box. The upper switch is the on/off. The lower is forward/reverse incase it gets jammed.
Edit to add the crush picture with gap set at about .038. Looks pretty good to me.

If your drill is smoking and "stinking up the house" there is something wrong! Please don't risk catching it, yourself, or your house on fire! Drills are cheap. New skin and Houses - not so much...
Looks like the same gear motor I'm using (177rpm 40 in-lbs) except there's a shaft extending out the back of mine. Did you get that from Surplus Center? Got mine quite a while ago. Don't believe they have it anymore.
Huaco said:Can Stepper Motors be used successfully in this application?
My cord and all the wires in the box are all 16 gauge.What size wire are you guys using for the connections between the switch/motor/capacitor? I was planning on 16 ga.
If you put steady voltage on a stepper motor do you get it's 100% duty cycle rpm? If so, and the torque and RPMs are acceptable I'd say yes. I don't think you would want to control one and use the stepping function.
Huaco said:No, wasn't considering controlling one... Just mounting it and running a set rpm. I dont know injury about motors... Any experienced motor guru in here?
Huaco said:Stepper motors can change speed though, right? They are used on CNC machinery for X-Y table control. Those motors don't always travel full speed when the table is moving... so that leads me to believe the RPM can be varied.
Correct. Kinda. They move in steps. A computer program and interface tells them how far to go and how long it should take it to get there. It's not like putting 9VDC on a 12VDC motor and getting 3/4 speed.
Huaco said:So... they get a signal from a computer (cnc controller) that tells it how many steps to take and how fast those steps need to be? Hmm... I bet there are some Sparky's out there that could make it work. I however, am not one.

marcb said:Interestingly enough, an 18" box did not appear nearly as large when on paper! The base of the hopper holds well over 30 lbs of grain.
jeepinjeepin said:It's 18x18x18 above the chute?!?
e-bay 25 for the motor and 40 for the controller.
Huaco said:Any details on what to look for? Is this motor powerful enough to crack through the toughest of grains? I assume so, with such a high torque rating. It just seems low on HP.
Would servo motors work?
