I found some picture on ebay of this motor based on the part number on the label.
ABB UGTMEM-06LB47S Servo Motor 6.1A 235V

I also found a pdf on the manufacturer website. I don't see the exact model on the pdf though.

No need to tear the motor down I think we have the dimensions in the last page of the pdf file.
But we will open it to check the dimensions though.

Nice. Thank you for understanding.
Moving on:
Yes that small part above the motor is the tacho, that should be replaced by an encoder, and new shielded wires from them sent to the control box.
OR <<<<<<<< This is OR,
If you can afford to get the new motor and drive i linked by the end, that would make wiring much easier for you as you would need only 4 unshielded wire to the motor, so no grounding and shielding problems, and much easier to install and setup, no tuning required, etc.

Good. I'm all for making things easier to work with and maintain later.
I will update the list and post it here soon.
You mentioned earlier that we can use both the small and the big plasma cutter. What are the components needed to achieve that?
And we don't need to touch the other motor I posted in the first page, right?

I sent an inquiry to eusurplus to get their take on the upgrade and they recommend these additional items:

DB25 cable to connect the boards
Support plate for 7i77 board
7i84 for buttons if I want to have a panel
Support plate for 7i87

My friend is building a custom box for the computer and the boards.
Do I really need those support plates?
What about the 7i84?
As for the the DB25 I think it is required.
I think I will need a box of cable connectors and crimp ferrules of different sizes too.

We have several options for the computer we are going to use with this setup. I have a mini-itx board which might do the job and fit in a box with the other cards. It has a PCI slot.
Intel® Desktop Board D945GCLF2D
ark.intel.com/content/www/us/en/ark/prod...oard-d945gclf2d.html
It uses an Atom 2x 1.6Ghz CPU. has 2GB of ram.
We can always go higher in specs if required.
I just wanted to add this here for more details.

1 more relay for switching the THC inputs, so has to be double contact double throw. And 1 more relay for the other Plasma, single contact will do.
The link i sent has them, so just add another 2 to the list.
Again the motor, we are talking about the same motor on the Z axis, no other motor should be changed.
That Z axis motor should not be changed if you go the complicated route with more wiring and tuning and adding an encoder.
Z axis should be changed if you go the more expensive route, but easier to setup and wire, this version is with the Lam Techologies drive i sent the links.

OK for the more expensive route and easier setup.
This means the whole part in the bellow picture will be removed, right?



Do you confirm the one on the list is of the right dimensions/specs?, Just checking :-)

- Motor => OK (75€)

What about the DB25 connector and the support plates?
I guess the DB25 connector is required. For the plates we are making a custom enclosure so no need I guess.
I don't think I need that button board (7i84) either.

Yes that is correct, that assembly goes out if you go the expensive route.
The DB25 connector is a must. The plates and the 7i84 are not a must have, but instead of plates you can get the raisers for the 7i77 for mounting it to a DIN rail as you will also ned some of that DIN rail to mount the relays.
