Output voltage from mains driver?

[JW1977]

JW, either drive would work. If you never run the motors at high speed (or not for long periods of time), then a higher voltage should not be a problem. A higher voltage would give better acceleration/performance, but the big risk is overheating the motor. That could be counteracted by reducing the current, but then you would lose torque.

You do realise that even though the DM's are high voltage drives, you still need to provide an appropriate input voltage? So the only thing you would realistically save, is a bridge rectifier and capacitor(s), as you'd still need an appropriate transformer.

Yes, i realise that, now. I thought the DM2282 had a built in PSU ready for mains DC.
As i mentioned above, optimum would be about 66V for the stepper and the PSU would give about about 68V IRL if use a 50V transformer.
AM882 can be supplied with up to 80V and handle 8,2A so the figures add upp pretty nicely.
Leaning towards 3x AM882. (Can they be bought fair closer than China i wonder?)
