I just got a box of 22 stepper motors. I’d like to go thru and figure out which wire is which while I still know how. Then mark the info on the stepper motor. Is there a standard for labeling the wires?
The 5-wire one I’ve already marked I used: “Common”, A, B, C, D
A is a wire picked at random. Applying a pulse to A and then to B makes it step clockwise. B then C another step clockwise. Then D. And back to A.
But I just saw another site that labeled
A - “positive” end of coil 1
B - “negative” end of coil 1
C - “positive” end of coil 2
D - “negative” end of coil 2
Is there a standard, or does everybody do it their own way?
