"Found" stepper motors - no datasheet available

jremington:
That is a four phase unipolar motor, which means that two windings are usually activated at the same time. The current per winding = 24 V/75 ohms = 0.3 A, power per winding = 24^2/75 = 8 watts (roughly). A very simple four transistor unipolar stepper driver will work fine. The motor will run on lower voltages but provide less torque.

You will have to determine the order of winding activation by experiment. For reference, see this http://homepage.cs.uiowa.edu/~jones/step/

Thanks for the link. It is very informative. I know just enough electronics to be dangerous to devices and this treatise is written well enough for me to understand it, mostly.

Based on all this, I am ordering:

1 - 24V DC 2A power Supply adapter (brick style)
5 - 5pcs ULN2003 Stepper Motor Driver Board (1 spare)

Thanks, John
