complete conversion kit for AMA25LV

Done some research and will start to collect parts for my AMA25LV conversion.

For X and Y will use 5mm pitch 16mm ballscrew driven direct from Stepers Nema 24 4Nm
https://tinyurl.com/yyg2v3rk - hard to find get those Nema 24 with 4Nm

For Z will be 20mm ballscrew (double nut) 5mm pitch and Nema 34 - not sure what torque yet 8-10Nm (will use counter weight, 2spindle R8 and 2.2kw wet)
https://tinyurl.com/create.php 8.5Nm

Wonder if hybrid motor with close loop is not overkill?

Here is open loop version:

https://tinyurl.com/y53kcevf - Nema 24 X-Y
https://tinyurl.com/y5rcpmx9

https://tinyurl.com/y5zt582y - Nema 34 Z

Any advice kindly appreciated

The motors look fine. I have almost identical on mine. However.
I had to run my nema24's on 60vdc and my nema34 is a bit junk on 60v and is crying out for at least 80vdc.
Bear that in mind when looking at drivers and power.

Personally. I would get drivers that can run on ac power and use toroidal supplies.
That's the route I'm going next (that's if I decide to change to a closed loop system).
