The main deal breaker for fast stepper motors is inductance, the lower the inductance = the faster they can spin at a given voltage.
And i do have Nema 23 small motors that can do way over 3000RPM at decent torque with 72V and Lam Tehnologies drives.

Can you tell me what drives those are? I could kinda maybe use those.

I just checked. The New NEMA 34 motors I am using with the Lam DS1076a driver Tommy made me buy can do 2000 rpm which is rapids at 36 m/sec at 5 m/s^2 acceleration. Thats using 2 on the 30kg gantry with 5:1 belt reduction

Who? Me?
:evil:

It works both ways Tom, I have a air drill sitting here I was coerced into buying by a certain Mr Rod.. Lol, I will set it up.. One day.. I think a RoboDrill would be a interesting project.

Got my toroidal transformer today,

Brought it from Tortech, I was going to get a custom wound unit that would output 80Vac but they found a old unit in their warehouse that will output 73Vac and they gave me a large discount on it.

1200VA - 73Vac output,
