I emailed the company to see if I can get a schematic
I am no expert on this, but my understanding is that you need a fairly high HP DC motor of the type used in treadmills if you want decent torque at low RPMs. 1 1/2 HP sounds like a lot, but you might be able to stop that motor from starting with your hand, depending on what you have. Also, many of those motors are not rated honestly. If you will not be going to use really slow motor speeds, then a smaller motor is probably just fine for many applications. Again, I am certainly no expert on this.Are there 1 to 1-1/2 HP treadmill motors?
I'm interested in replacing the spindle on my Grizzly mill (704) but I'd like to stay in that power range. My main reason for wanting to change is really just to get faster spindle speeds and CNC control of Motor On/Off and speed.
I have 220 available, but just like a dryer outlet - not 3 phase. I run the Grizz on a 110 outlet with lots of other stuff so I know it could handle the load without popping breakers at inconvenient times.
