Change the wires to reverse the direction of a 2-phase stepper motor.

Filed under: Stepper Motors — mota @ 7:14 pm

Sometimes it’s necessary to mount a stepper motor in a different orientation, or the opposite direction is needed at the motor, but there is no access to the driver control – given the same pulse and direction signals.  Using 6 lead wire unipolar driver, how do I change the wires around to accomplish this?

A: The A-phase lead-wires are normally Black, Yellow, Green.  The B-phase lead wires are normally Red, White, Blue.  To make the motor go in the opposite direction, swap the Black and Red wires, and swap the Green and Blue wires.
