20 pcs of NEMA17 and NEMA23 control with Arduino

Other Hardware Motors, Mechanics, Power and CNC

Hi folks!

I would like to ask for Your experience with NEMA17 and NEMA23 control? I should make a system to control 10 pcs of NEMA17 and 10 pcs of NEMA23. I did research in internet and found some information, but I would like to read Your suggestions.

So my questions is:

  1. Best solution for this work is to use Arduino Mega?
  2. Driver for NEMA17 and NEMA23? For NEMA17 use А4988 and for NEMA23 use TB6600?
  3. Power supply to handle current. No more two or three motors will work at same time.

{1} The Mega has the advantage of plenty of I/O pins. You will probably need at least 40 for 20 stepper drivers.

{2} The choice of stepper driver depends on the specs for the motor. Nema 17 and Nema 23 only define the size of the front face (1.7 inches and 2.3 inches). Please post links to the datasheets for your motors.

{3} Stepper motors draw full current even when stationary - that is how they hold position. If you disable the driver (which would require another I/O pin) you can't be certain that the motor will be in the exact same position when it is re-enabled.

It will be much easier to give useful advice if you describe the project you are trying to implement rather than just asking a question about a small part of it

Thank You Robin2 for Your comment! I checked Your links, thanks!

I'm so sorry but I can't describe the project yet, that is secret. I have NON-DISCLOSURE AGREEMENT for this project.

Last thing what I want to understand it stepper motor current consumption is nominal current or not?

Stepper motor current consumption is what ever you have set it to with the current adjustment on the controller board.

That makes me think that this is a commercial project and you are hoping to increase your profit by getting free advice from us. That's not nice. For a commercial project get professional advice.

Yes, it is! I don't want to increase my profit, profit will be the same. I want to learn new things by this projects. First time with stepper motors, this is why I asked for Your recommendations.

I suspect if you have to pay for professional advice the profit will be reduced.

Why not create another project that you can share with us that demonstrates the problem you are trying to solve.
