Google is amazing, however here is everything I ordered minus the motor:

Motor: Find one on craiglist.

EDIT: I don't know if that motor is reversible, or what your mill specifications are and wether you need a reversible mill or not. So, do some research on that aspect, but the other neccesary specifications for motor are all there.

Theres one. I bought mine for 10 dollars.

I went round and round with this looking for a motor with a slow enough speed for my barley crusher.

Ended up with one of these for 38 bucks on sale:

I couldn't ask for anything more, Can turn it to run as slow as 50-60rpm or faster. Has a lock that you can engage to keep it running without holding the trigger down. You could easily mount it to a board next to the mill

I am going to piggy back here, what about adding pullys to increase motor speed? I have a motor that has a ton of torque but runs at 1.25 RPM which could take a while to crush grain. Is this feasabile to ramp up the speed?

You can. Not sure how much faster you can make it. Also, your torque will diminish as the speed increases.

can anyone help me with this motor..

will this motor do the job ??

http://www.ebay.com/itm/DC-MOTOR-1-...7755168?pt=LH_DefaultDomain_0&hash=item460099 4420
that is a 90V DC motor - you CANNOT plug it into the wall, it requires 90V of DC power. Houses are typically 120V AC power.
If you have an electrician friend, it could be converted - it will require an isolation transformer, a bridge rectifier, and a smoothing capacitor.

you can poke around here for something like this for $30:




- you can probably take that fan off the back...68rpm isn't fast, but the torque is plenty high, you can dump your grain into your hopper and walk away while it does the job...

You should not buy a motor (unless direct drive) for more than 20 dollars. 1750 110ac motors are so common.

Go to the local scrap yard. I picked up a 1725 rpm, 1/4 horse for 3 bucks. They sell them by the pound. If it ever goes bad (which it probably won't if you pick out a good one) sell it back for scrap and buy another one.

i can't open that link for some reason.. il have to find a different computer
You need the Adobe Acrobat Reader plug-in for your browser to load that page.

fwiw, it's a bit dated, but the information should be useful for those seeking to transform the typical 1700rpm motor into something that can drive a malt mill...

Cheers!

Check out the Surpluss center, Guarantee they have everything you will need. I have purchased alot from them when I was building the hops picker and the selection and prices are fantastic. Did you pick up the rhizomes yet?

I have the MM3 2.0 and I ended up buying three motors before I got one that would work. You will need 80 in-lb or more torque and want somewhere around 150-300 rpm. The first motor I bought only had 40 in-lb at 220 rpm and it would get stuck with only a hanful of grain thrown in. All of the motors I bought I had setup as direct drive. This is just my experience. Good Luck.

I assume you would be looking for a motor with the following specifications:

120 V (sometimes noted as 110 V)
60 in-lb (or more torque - I would go with 70 or more probably)
AC motor, not DC

From researching during my motorization I think you want 150-300 RPM.The motor can be geared down but I suggest direct drive if possible.

This motor I would assume would be 1/3 HP.

This is from my Research/experience with my own MM3 2.0

yah.. well i don`t want direct drive cause i wanna mount my motor underneath my stainless steel table and have the mill on top so i can have a table to put grains on or anything.. and hide the motor...

maybe il just outbid this guy and pay way to much on ebay for a motor but atleast i know its one i can use...

don't get into a bidding war on e-bay. you only drive up prices unnecessarily.

log in 2 minutes before end-of-bid. Decide on your top price - you won't have time to react and change, so pick what works for you.

Now, last 15-20 seconds, enter your bid. No one else will have time to react - If they've got a higher bid, you lost it, if not, it's yours.











you're welcome.

You could probably use a bench grinder. Already wired for ac power but might need to mod it some.
