Anyone use servo motors /drivers

hi guys and thanks for your responses .
All of these appeal but only for my next project because I am already committed on my first one.

Not sure yet how to calculate power requirements so maybe 2Nm would be adequate ?? I guess it involves table inertia on the one hand and maybe mitigated by reduced motor acceleration, as well of course as the cutting forces which of course will be dependent on materials , cutting speeds , etc, etc , etc. maybe have to hunt out my college notes from 50 years ago.
Is there a simpler accepted way??

One advantage of some of those shown might be simpler wiring connections at the motor end cos the the basic motor with 8 wires hanging out of the back is hardly easy to connect in a tidy manner.
I have aero plugs at my panel end of my current project , but the motor end does not look good.

The whole compound table is 60kg in weight which is not far off a G0704/ PM25/ AMAT25 x,y table.
These machines are usually kitted up with between 425 & 570 oz/in (3 to 4nm) nema24 steppers at the lowest inductance possible.
Food for thought.
