Hi All
I'v been merrily using my CNC plasma cutter that I built a couple of years ago with some very useful input from you. and for that I'm very grateful.
The plasma build was based on a kit from Zapp that works very well.
I've now been given three small steppers
http://www.rotalink.com/pdfdocs/M142618M426.pdf
The details are
Model Number M142618M426 Phase voltage (V) 7.4 Phase current (A) 0.28 Phase resistance (Ω) 26 Phase inductance (mH) 19.2 Detent torque (mNm) 4.9 Winding Bi-polar
So what sort of drivers should use and how do I work it out?
What power supply do I use and how do I work it out?
Would I "get away" with a 12v power supply? Does it just need to be 3x the 0.28A so approx 1A? ..... or am I barking mad?
My forte is the mechanical side, electronics\electrics are still very much a steep learning curve for me, but having the reasons explained should help others in the future too as well as allowing me stop asking very similar questions.
I'm sure someone will ask "what's it for"? So far I've no idea - they are not powerful so probably something that will control pyrography iron, a laser for paper cutting or maybe even a 3d printer print head?
I hope this helps and look forward to hearing form you soon ;-)
