Hi there,

I've ordered a 4-axis unipolar kit from Xylotex and I have also bought some motors. The motors are rated at 4.5V and 2.5A/phase and I currently have 3 of them, but plan on getting a 4th motor in the near future.

What would the ideal power supply be (ie. current and voltage) for this setup?

I'd also like to check if it is definitely safe to run stepper motors at a higher voltage than they are rated at. I still have my doubts about running them higher than they are rated and would hate to destroy them, because I wasn't paying attention... (can anyone convince me???)

If they can be run at higher voltages, would a 12V 10A supply work (I can probably get a PC power supply like this for almost nothing...)? Also, would a 24V 14A supply work?

Finally, I'd just like to check, there is no current limit on these Xylotex boards, is there? The only limit is voltage, right?

Thanks (and sorry for the question overload )
Warren
