Hi....
I bought 2 pcs used step-syn stepper, but I do not find the datasheet.
I ask if anyone knows the specs of step-syn stepper.
Stepper type :
1. 103-8573-5040 (10 wire 5 phase)
DC 2.8V/2.8A, 0.72deg/step
2. 103-8573-7011 (5 wire 5 phase)
0.75A, 0.72deg/step
3. 103-8572-7041 (5 wire 5 phase)
0.75A, 0.72deg/step
i attached the picture

Thanks

Use this page to work out the wiring:

And measuring the torque isn't terribly hard:
