Hello,

I'm looking to get the Stepper Motor - 125 oz.in (200 steps/rev, 600mm Wire) and use it in a project.
What kind of power supply would this require?

The project will turn out something like https://www.instructables.com/id/Arduin ... uct-Photo/

Hi ryurkovich, and thanks for posting!

At maximum torque, ROB-13656 is going to need 2 amps per phase. Since this is a bipolar (2 phase) motor, you're looking at a maximum of 4 amps for a power supply.

Our Global Power Supply - 15V 4.34A would work with that motor but I see from the guide you're looking at that they use a much smaller motor and a stepper motor driver sized for that motor.

If you would like to stick to that guide, I'd recommend using a smaller motor like ROB-09238 and a suitable power supply for that motor would be TOL-15314. Both those should work nicely with the guide you're following.
