Nema 23 4Nm Stepper Motor

[Shinobiwan]

Now sold.

Hi Ant, could you share about the 'closed loop' set-up? I guess this is servo? Please post on your Strike thread :)

I'll put a video up next time I cut something along with a pic or two.

Its not servo but closed loop stepper. Basically a stepper with an optical encoder and matching driver. Works quite well but limited speed and torque from this bottom of the range offering. Its only 50v and 2Nm but that's OK for a Z axis. You can get bigger and better versions based on the same tech but I wanted to try it out before committing to that sort of outlay.

Jazz covered the same model in this video



Bigger, badder version here. This one runs upto 100v and 8 or 4Nm depending on the motor model you choose. I'd go with these for the X and Y if you've got a some weight in the gantry and a large cutting area.
