Hi. I'm doing a project. I'm just asking you guys what's a good stepper motor driver for Stepper Motor Nema 34: 113mm 84kg-cm 85BYGH450B-004. And is it enough to use 12V 5A power supply for this stepper motor? Thank you for the answers.
Ideally you use a higher voltage to get the best out of the motor, up to 50 or 60v. Use a modern current controlled driver, look at stepperonline to find a suitable one. The tiny 4988/8825 style drivers sold for use with Arduino aren't really suitable.
Yes. I also want to ask if the DM556 stepper motor driver is enough to control my NEMA34?
That looks perfect though apparently obsolete and replaced with the EM566S.
And the required power supply to use is something 24V 5A, right?
24v would work but higher will give better performance, max is 50v. If you set your current to 4A on the driver the supply current will be somewhat less so a 5A supply should be fine. Driver datasheet is here: https://www.omc-stepperonline.com/download/DM556T.pdf
Thank you so much @jhaine.
