The ACM motor will run on a 230V driver or 400V three phase driver, but you need to check if it has a resolver or encoder.
I know this motor quite well and a lot of them came with resolver.

The second question is about their planetary gears. Could I use them in CNC application with their 3 arcmin and 5 arcmin backlash?
