Hi Gigabit878, In a three phase induction motor, reversing any two of the three wires will change the rotation direction. In a single phase induction motor, the direction is controlled by a starting capacitor. Change the pole on which it it placed will reverse the direction it starts and then runs in. For synchronous motors, a shading ring (often copper) is placed on one of the armatures - swap the ring location to the opposite armature.. For universal motors, swap the wiring of the brushes.
