polyglot:
where you might have a rated current of 3A, about 0.5R winding resistance and want to drive the stepper with about 48V. Clearly those numbers don't add up if you just think of the stepper as a resistor.
Apology accepted - I was mainly concerned that your long post would confuse the OP.
I am well aware of the stuff I have quoted above, and I had not explained this in my earlier reply because the OP was already planning to use a suitable driver.
There is no shortage of other newcomers trying to drive steppers with unsuitable drivers.
