Thread: High Torque Motor Z Axis

Hi,
I appreciate for the cost difference it’s probably not really worth questioning but is it really necessary to have a high rated motor for the Z-axis?
This would be for a cnc router machine, flying gantry style, machining wood, shallow cuts, reasonable federates.
I'm currently designing a new machine, and the Z-axis is what I’m currently working on, I would like to use the smallest physical size motor I can, as the machine is specifically being built for the propose of sheet work and the material being wood (ply) for the most part.
I'm just wondering if I’m going down the right route thinking that I won’t really need a big powerful motor for the Z-axis, it’s quite relevant for me as it would mean I’m happy to mount a smaller compact nema23 motor directly above the Z-axis lead screw, vs. going with a bigger physical size motor, mounted off the back of the z axis connected via a belt drive.
Thanks guys, Lee.Me
