Ok, I've since found specs for an AMP - Applied Motion Products #4034-326 stepper motor which looks A LOT like mine. Similar specs as well(at least for those i have...):
2.5" long, 212 oz-in, 6 wire, 1.8 Deg/Step, 2.5V, 3.32A, 0.8 ohm, 5.0Mh, 3.0 lbs.
2.5" long, 150 oz-in, 6 wire, 1.8 Deg/Step, 1.8V, 4.70A, 0.4 ohm, 1.3Mh, 3.0 lbs.
My KP86LM2-005's say or measure:
2.5" long, ??? oz-in, 6 wire, 1.8 Deg/Step, 1.8V, ???A, 0.4 ohm, ?Mh, 3.0 lbs.
Bear in mind, the 0.4ohm is measured across half a coil(well, between one end and the center tap), or in a unipolar configuration, and the series resistance on mine equals 0.8 ohms the same as the example sited. I don't have an inductance meter or I'd verify that as well.
Okay, here's the $64K question, from the above similarity in specs can I somewhat reasonably infer that my motors might draw about 3.32 Amps, and provide around 212oz-in if connected in series mode?
If I have a bipolar driver, would I be better off using only half of each series pair of coils? Would I be giving up 62 oz-in of holding torque vs. using the whole coil on each side? How would I then interpret my voltage and current in that configuration? (1.8 Vdc @ 4.7 A?, or 2/3 that amperage?)
I know some of you must have had similar experiences, take pity and tell me what you think.
