Stepper wiring

For any stepper motor to be wired up properly, we'll need to determine which wires are "pairs" or connected to the ends of each coil.


Using an ohm-meter: On six-wire motors you'll find two groups of three wires in which all three wires are electrically connected to each other. These wires are connected to the same coil, one in the center of the coil, two at their ends. Accordingly, two of the possible pairings have a lower resistance, one pair has a higher one. Take the pair with the higher resistance and ignore the third wire.
