Im trying to figure out what 1hp 1750rpm motor I should get for the coote 2x8x72 grinder...I decided on the 3 step pulley system. Im alittle confused as to if I need a 3 phase or 1 phase motor? This grinder will be on a dedicated circuit if that matters? Any help would be appreciated...its all coming together!
 
For a one horse motor, use single phase. I have a Leeson farm duty motor, and a three step pully set up on my kmg. I have it on a dedicated 110v ac circuit and its fine for knife making. Use farm duty motors as they are designed to be on for long periods.

I have a 1/2 hp for my coote but I bought a 1hp because it can bog down occasionally. Unfortunately the 1hp requires 13 amp and I'm on a 15 amp circuit. Get a 1hp and make sure you have enough juice to run it. I have a single pulley on the motor and a 2 step on the coote itself. What size wheel are you using? I have a 10 and a 6 with the 4inch idler and 2 smaller idlers. I would suggest a single pulley on the motor and a 2 or 3 step on the coote with the small pulley the same size as the motor pulley, this will give you 1750rpm at the max and slower as you step up the wheels.
 
Ideally a TEFC motor... Totally Enclosed Fan Cooled... It is sealed to keep the metal dust from the windings on the motor.

1Hp 1Ph 110v TEFC

3Ph requires the use of a phase converter, VFD etc, as your house only has single phase power.
 
We bought a 1 1/2" hp tefc farm duty motor for ours not long ago. Never bogs down, good motor. Got it at TSC and bought a 3 year parts,labor and free shipping warrenty with it for $30 or so..Makes me feel better having that good warrenty on an expensive motor.
 
I think I am going with a leeson 1hp farm duty, single phase...I am going to run a dedicated curcuit today, should I wire it 230 or just single throw 110? Also, I have never hooked up one of these motors before, in the diagram on the leeson site it shows about five or six connector prongs..whats up with that?
 
If you can, wire it for 230 and wire the motor for 230. It will take less amps and then you can use the line for an oven later on. there should be a diagram on the motor housing to follow. You don't need to hook up all the wires as some are jumpers depending on what voltage you are using and which direction you are running the motor.
 
The electricity used is the same with either. The total amperage draw is the same, the load is just split across two legs. I don't see a big advantage to wiring this for 220 if he doesn't have 220 already.

If you can afford it I would go with a larger motor.
