What is the "Biggest Bang" I Can Get With My 2A Stepper Drivers

[silver]

I'm limited to a maximum of 2.00 amps on the stepper drivers I'm using at 12-42V. These Rogers Labs drivers are somewhat dated (late 80's early 90's is my guess). What is the largest stepper motor (oz/in) I would be able to use with these? Are there 200 oz/in steppers out there that would work off of 2 amps?

www.hobbycnc.com has steppers that are 200oz/in 3amp max

We have 3 Nm (425 Oz inch) 23 frame that are rated at 1.4A series and 2.8A parallel.

Are your steppers Polar or Bipolar???

They are 8 wire so can be used in both bipolar or unipolar, but the torque of 3 Nm is bipolar, in unipolar it is 2.15Nm
I have attched the datasheet.
