Run 12V stepper with 5V??? [SOLVED]
January 17, 2011
Hey guys I have a quick question. I've never used a stepper motor before, but I have one that will fit my new robot nicely. It is a 12V motor kinda like the one below
I don't have a 12V power supply right now, only a 5V. I want to know if this motor works before I go and buy a new battery. Does anyone know if it will even work with 5V? I just need it to move just enough to let me know it works, then I'll go get a battery.
Note: I'll be controlling the motor with a project board that has H-bridges on board, and I have the coding almost finished.
I was able to get the motor working with 5V. It's very weak but it's enough to let me know it works. Sadly, I didn't notice what it's top speed was...about 13 rpm, much to slow for my need. I wish I would have seen that before I put time into it, but at least now I know how steppers work. The motor is a unipolar motor with 5 leads, it was pretty tricky to figure out how to wire it up, if anyone ever has one and doesn't know how to use it, holler at me.
