I have selected drives as linked below.

What power supply to use for 4 such motors. 1 Z,1 Y,2 X
Can I use a transformer from 220VAC to 48VAC?
Should I go DC?
Should I use 4 different supplies or use one big supply?
The next is this spindle.

I am looking for VFD for this spindle. I saw this from ABB. Will this work? What else would I need to make this work?

Please help. Can't decide electronics ????

The drives state they can take an Operating voltage: of 20-70VAC or 30-100VDC.
I'd likely use one or two toroidal supplies (depending what va size you can get) that can give 60VAC to the drivers.
Prob end up using a 30v*2 wired in series to give out 60.
Afaik the voltage tends to rise over the rated amount when idle hence why I'd leave the 10v headroom by not going the full 70.
@maxtec54 I have industrial supply line dedicated 125kva in my workshop. 3.5Kw should be enough to drill 25mm dia holes through 50mm thick steel I hope?
@dazp1976 thanks. And just to clarify I think you asking me to get center tapped supply?. What would be the current raiting that I will be looking for?
