If no, what servo motors are recommended?
If yes, what servo controller drives are recommended?

Thinking of using 5mm pitch ball screws.
What pulley ratio should I use?

Thanks in advance

For a similar question and my answer.

The motors you are asking about are less powerful and more expensive than the ones mentioned in that thread.
