I bought this stepper motor from All Electronics. They don't have much info on it and Google doesn't turn up anything that's not on the All Electronics site.
It's a five wire motor with resistances as shown in the attached table. I have confirmed that the black wire is common and the stepping order is red, orange, yellow, brown.
The motor is very different from the (few) other steppers I have experimented with. (1) It doesn't seem to have permanent magnets; when the shaft is manually rotated, there is no perceptible feeling of steps or resistance of any sort. (2) The step angle seems to be 15°. (3) The torque seems to be very low for a motor of this size, but since I don't know the proper operating voltage, I am using only 5vdc.
Any insight (or firsthand knowledge) about this motor would be appreciated.
