Found what may be a suitable transformer 36+36v and 625va

That is a good company. Before you buy it. state what final output voltage AC or DC you are trying to achieve and with what drives you will be using.

Personally I think 625va is a bit overkill . I use 4 nema 23 3.1Nm on my router with 500Va

This would be better. 625Va is too much and you could run into issues with in-rush trips. 500Va is plenty and like I said you could get away with 300Va but doesn't leave much upgrade room.

However, you must wire in parallel, not series because you'll have 70Vac in series which will give 95Vdc + when rectified to DC and that will produce Magic smoke from those drives.!

If you want to go with series wiring then look for 2 x 20V 500Va. This will give aprox 55Vdc

Choice is yours.!

I noticed earlier you linked to Bridge and Caps. The bridge is correct but the Caps are wrong. 330Uf is far too low

You want to be looking for 3 x 100V 4700Uf. You could use 4 but 3 will work fine.

I guess with 55Vdc I will hve to go with 80V controller then (the next one donw being 50V)?

Yes or if you want to use with 50V drives then size transformer accordingly. Just remember you need to leave a 10% safety margin so don't size transformer to give 50V or even 48V.
