Ok thanks.
That clears things up a bit.
I will get the low inductance motors and use the transformer i have.
I will keep an eye on motor heating and can always swap transformers later.
Look for the lowest inductance motor you can and run them at the highest voltage your supply can generate and/or your drivers can handle.
The formula you are using to calculate the voltage is just a recommendation.....a ballpark figure. The bottom line is the higher the voltage the
faster the motor will run without losing steps.
