Connecting Bipolar Stepper Motors in Series

New to Arduino here, need help trying to connect three bipolar stepper motors and three stepper drivers in parallel, connected to one 12V power source. Any help appreciated!! :slight_smile:

If you have the same number of drivers as motors, what is the problem?

Not sure how to connect them all to the power source in parallel..

three stepper drivers in parallel,

Then why does your title say "in series"? Perhaps you should correct the title.

I'm not sure that I understand your question, but I would simply add extra wires to the 12v power supply so I could connect it to each of the stepper drivers.

12v + ------------------------------ Driver1 +
------------------------Driver2 +

12v - ------------------------------ Driver1 -
------------------------Driver2 -

Make a pencil drawing showing the wiring arrangement you are thinking of and post a photo of the drawing. It is very easy to misunderstand written or spoken wiring instructions.


Welcome to the forum.
What is your application?
What are the specs on the stepper motors, post links to data please.
What are the specs on the drives, post links to data please.

What is your electronics, programming, arduino, hardware experience?
Is this a school/college/university project?

Thanks, we need this info to be able to give you an accurate answer. Tom... :slight_smile:

Sorry for the confusion guys (lack of sleep from this project) and thank you for your help! Fortunately my team mate has figured out how to connect the drivers and steppers in the way we want :slight_smile:

Great to know there are people prepared to help when I'm stuck,

Thanks again guys!

Great that there is a feedback.

But for the sake of other newbies:
What did the team mate do to get it work?
Did he follow @Robin2's advice?
