For those motors you could do worse than these drivers from Zapp. what drivers did you have before?

i have nema 23 3nm motors, on pm542 drivers from zapp driving them with 40v power supply , they work really well together , 4.2 amps parallel , tried to run those motors at 2.5 amps 24v, before i upgraded .
waste of time and money, to slow and motors stalling. now have plenty speed and torque .......... maybe have to upgrade machine now. at £35 you cant go wrong

Irving, the drivers I have / had were common off the shelf units purchased from Australia, they’ve worked well but are limited to 40v 2amps output and I ran one against this motor at 24v with the windings in series, I thought I may get something out of them.
The reason for buying the bigger motor is to beef up what we already have and we like to experiment / learn.

John, many thanks for the info, it’s great to have positive confirmation of our needs.
