 		Hello,
Since i am collecting parts for CNC mill, i need some high end steppers, it would be best to use 5 phase stepper motors due to larger division of steps ( i will use 1um encoders for feedback)
I have SKM400GB125D and SK200GB125D igbt's, HV capacitors ,x ray tubes, lot of power mosfets in to-247 and isotop packages >500V

 		Hi Linas

I got some different stuff, maybe you can use it...

Driver board C7576-004 with Vexta IC "EIC0202" and Vexta stepper motor 2-phase 1.8 degree/step DC 3A 1.5Ohm A5109-9412K: Link2

Some other driver boards and different steppers (From picture 147 to 152): Link2

 		Well, after talking with Yoda equivalent, i should go not to steppers, or 5 phase steppers, but AC servos instead.

So better would be to get 3 identical AC servos at least and CNC Ethernet Smooth Stepper board for control, it looks it will give best results

 		I recommend Yaskawa or Mitsubishi servos, Sigma III or newer for Yaskawa and MR-J2 or newer for Mitsubishi. They have real time auto tune which will make your life much easier.

Dont try to mix and match servo motors and drives, you will regret it. Most modern servos now use serial absolute encoders with proprietary protocols, but they offer insane resolutions, I have Yaskawa motors with 1 million count per rev encoders.

Do you have an idea of what Torque and speed you need? (or at least power rating?)

I do work for a motion control firm. I could see what we can do.

I assume pulse-direction in? (I personally recommend analog for such an application if you can find a suitable motion-controller.

It depends on how you want to set it all up.

Already spend >1k for Teknic clearpath enhanced servos amazed
