Hi,
This is technically a 40VAC output transformer, but has two 40V windings. If you connected them in series you'd get 80VAC. Once 80VAC is rectified and smoothed
it will produce 110VDC. That would match 80VAC or 110VDC input stepper drivers.

The same company produce linear DC supplies, which are a stepdown transformer, rectifier and filter capacitors. This is a good example, 80VDC, 12.5A output (1000W).

Note that transformers and linear supplies, ie based on a transformer, are very rugged and will handle brief, but very substantial overloads. Switch mode supplies are cheaper and widely
used because they are cheaper, but they do not have the ruggedness and overload capacity of a decent transformer/linear supply.

These are some examples of low inductance steppers. Note that many of them do not have spectacular torque output, and all absorb a lot of current. You might ask
'why do these thing hog that much current for so little torque'......the answer is that to make them low inductance you have to do that. The thing is that with an 80VDC to 110VDC driver
to back them they'll retain 40%-50% of their torque to 1000rpm or better. So they have less torque but it hangs in where high inductance steppers die the faster they go.

Were you to build a machine using both low inductance steppers with a high, say 80VDC supply and 80VDC drivers it will go fast, and that is a prime requirement for many users.
These components are readily available but tend to be on the high side price wise. You can certainly save money by buying medium-high inductance steppers but only to sacrifice speed.
Your choice.

Just as an example I have attached a Speed-Torque diagram for a 57CM23. While it only has 300oz.in see that it has still 140oz.in at 1000 rpm, and that's with a 48VDC driver, imagine how much better
it would be with an 80VDC driver?
