So, I have a project that I’m doing with my uncle but it’s not cnc’s / lathes or 3Dp’s related and just some fun hopefully.
I think I know what I’m doing but could do with a eye casting over my idea. Also, I’m crap at electric needs and usage.
I have 3 Nema 17’s 45’s from a small project that never got started ages ago.
So basically, I need all 3 to rotate in the same direction at the same RPM. Don’t need bidirectional but need to keep the RPM under 110'ish (variable). No precision needed, torques not a huge factor, but it could be running several hours at a time.
I was thinking of a just a motor speed controller that can supply the voltage and amps with a suitable pot. That’s where I’m struggling to work out what I need or if indeed it will work.
Any thoughts?
