Personally I don't know anything on closed loop. However I would like to try them out at some point. I lkie the look of the electrical specifications on them such as inductances. I'm talking <2.5mh though
You have to serch around and pay decent, there is some rubbish around.
The one you've linked is NOT a good example afaic.
You could also look for sets with direct AC & DC input to the drivers and run a single toroidal supply to all of them.


You're better off just going this route:

Wire it in 'Parallel'.
Get some DQM860 drivers and use 60V on them. I have very similar motors and same drivers on 60V and they're cracking.
I mean you can always adjust the voltage down on the psu if you feel iffy. (you can't turn too small ones up!).
Many run these on 60v though on G0704 type mills etc.
