Hi, I’m trying to build a small self balancing robot using stepper motors. I haven’t used them before and need some help.
I would like to power the robot with a 2s lipo, 7-8.2v and am controlling it with a 3.3v esp32 microcontroller. I want something small so I would like to use nema 14 or smaller. I was thinking this motor https://www.pololu.com/product/1208 suits my voltage requirements but I’m not sure which stepper controller to use with it.
I saw some of the comments about using current limiting to drive motors above their rated voltage but I am unsure just how much overvoltage is possible. Like using a 3.9v stepper at 8v?
Or would I be better off running off using a 1s lipo (3.4-4.2v) and going with a lower voltage motor?
Any suggestions? I would like to order ASAP.
