I can understand that the UniPolar does not have good low speed torque but holds the torque at high speed. I can also understand the BiPolar Series / Parallel benefits & drawbacks.
But since I’m building my 1st CNC machine how do I know which one to choose for a hobby CNC router machine? Is it important to have good torque at high speeds or low speeds?
So which one is more popular? |
Hi kolias
The answer is easy. BiPolar
If it's torque you're worried about, then buy a larger stepping motor. eg. 400 oz/in or 750 oz/in
I cut aluminum on mine and I just have 275 oz/in
Speed is really not a problem, because every material has its own cutting speed.
Here's what I build.
