Hi.
I'm planning a fun project to finally get my first cnc mill. I've got the ideas for most things down but I'm still not sure about a good spindle motor. I'm finding researching this topic quite difficult because of conflicting information, so I'll ask on here :cheers:
I'd like my mill to have a similar performance to a Tormach PCNC 1100 because this is the mill that I want but can't afford. One of the areas that the Tormach is apparently lacking is in it's spindle power, John NYCCNC did a video to find it's limits and got 1.2 - 1.4hp so I think maybe 2hp would be better for me, for this I'll probably need a 2.5 hp motor to reach my 2hp cutting goals.
This brings me to the question, what type of motor would be suitable for my needs? I think most mills like the Tormach and some real machines use ordinary AC induction motors, but these are heavy, slow and I believe accel-decel slowly so probably not the preferred option.
So what do you guys think would be best for me? Also would like it to be as cheap as possible, sub $1,000 for motor and controller for motor.
Cheers, Fenza
