I didn't want a 10 to 12 inch pulley hanging of the end of my mill.

Convienence, currently use a 300 rpm drill at half speed. I plan to mount this unit permanently so it will be one less thing to drag out.

Can this mill be used with the high torque motor?

BEST ANSWER: Yes, but the mill and the motor don't have the same size shafts. So, you'll need to buy a flexible shaft coupling hub that'll allow you to match the two different size shafts. McMaster Carr sells them online. Their part number is 6408k14. You'll need two, one with 3/8" diameter and one with 12mm diameter. Then you'll need part 6408k75 to hold them together. Hope that helps.
2 wires coming out , 1 black, 1 red. I assume black is positive???
Laurence cooper on Apr 16, 2018
BEST ANSWER: The motor uses and external starter capacitor which will allow you to set the direction of rotation for the motor which is nice. I didn't need to change mine because of the side the drive shaft was on. Because of this you will have to use the include box with the on/off switch or remove and use the starter cap inside if you choose a different switch/box to control the motor.

There are two wires coming out of the box with the switch / starter cap, red and black. The black wire is the neutral and the red wire is the hot.

Technically it will work either way but that is the way it should be wired for safety. In the US for 120 volt wiring white is neutral and any other color but green/gray is hot (usually black for residential wiring). Green or bare wire is ground.

The motor is from Australia, that is why the wiring color is odd. There black is neutral and red is hot.
The video in the review shows a control box, but the product description states there is none, and several of the other reviews seem to indicate relocating a switch? Please verify what is included, thank you.
Jeff Black on Nov 27, 2018
BEST ANSWER: You get the motor, two couplers (10 and 12 mm), and what I guess you could call a control box. The control box is just a plastic box with a push button safety switch on top and a starter cap inside the box. You will need to purchase a power cord to plug in the unit and I would also recommend a cord grip to secure the power cord to the box. You can buy a power cord with a molded plug from the hardware store.
The kit comes with a coupler for 10 and 12 mm shafts. Is 12mm the same as 1/2"? that is the diameter of my shaft.
John Simpson on Dec 5, 2018
BEST ANSWER: It is meant to fit any Malt Muncher grain mills. Technically, 12 mm is approximately 0.472" so it may not fit. However, there is some extra room before the coupling is tightened down so 0.5" shaft may fit.
Does this come with a capacitor? Will it work with the Monster Mill 3 roller? (With 1.5" rollers, not the pro 2")?
Nathaniel Reynolds on Sep 23, 2018
BEST ANSWER: Hi Nathaniel - The extra roller shouldn't pose an issue as there is still only one drive roller. Please ensure the "lovejoy" coupler is compatible, as this accepts 10 and 12 mm shafts.

perfect motor
the perfect motor for the home nano brewery. we brew on a one barrel nano system (SSbrew tech) using larger quanities of grain. The bamboo board was warped on receipt so we mounted our Millars mill on a small stainless mixer stand on rollers. The stand holds a 10gal NSF white rubbish barrel on the shelf under the grain mill. The motor has plenty of torque and runs below 200 rpms giving us the crush we want without making flour. we are milling up to 75# of grain in a very short period of time.

minor issue
The motor itself is great. The kit could use some wiring diagrams. My spider coupling was terrible. Not even close to the correct size. I had to order another one 3/8" x 12mm to work correctly. I have the exact same mill/motor set-up as displayed.
Once I had this installed the motor-mill combo worked like a champ. Would rate it 5 stars if the spider coupling was correct.

Plenty of power
I use this motor along with a MM3 mill. Plenty of power and easy to connect.

Powerful little motor for the savvy home brewer
Perfect for my needs. It's relatively small and paired with my Monster Mill MM2 fits on a board that sits on just a single 5 gal bucket.

Wiring is trivial, but I do recommend installing a cable gland, it's easy and cheap and will secure power cable to the control box. Don't forget the ground wire!

The included coupling is metric 12 mm for the motor and 10 and 12 mm for the mill side. Do yourself a favor and order Lovejoy L050 hubs and spiders in 12 mm bore and whatever fits your mill (likely 3/8 inch if not Malt Muncher). They're like 4 bucks each and MUCH superior to what's included.

No issues grinding with the MM2 down to below credit card thickness gap. Plenty of torque for the average home brewing mill. A joy to integrate to my system!

Lots of torque. Sure beats hand cranking!

I paired my motor with the 3 roller malt muncher and hopper extensions. It grinds my 20 odd pounds of grain without fail.

Under Powered
Decent price, but far from a heavy duty motor. It failed within the first 3 weeks we had it. High torque, low RPM motors are hard to find though, so this is an option for light duty.
