Who can work there magic with these numbers?
The motor plate reads: Mo...1,52Nm
Lo....11A
U......51V
N......3000 min
I get that it is 51v nominal and 3000rpms at 51v. Is that 11A max or nominal? Is that 1.52Nm per amp or 1.52Nm stall at 11a? what's it work out to in oz/in?

A x V / 746 = HP

11 x 51 / 746 = .75 HP

That's HP in. Let's guess it's 80% efficient. .75 x .8 = .6 HP

Lot's of power. What will you use it for?

Thinking of using it for my z axis at 3000rpms I can run it at 3:1 and still get 1000rpms at my ball screws.

1,52Nm @ 3000RPM is 456W output.
