Three-phase motors can be made to change direction of rotation by interchanging any two motor leads to the main power source. Interlocks protect the motor from being energized to rotate in both the forward and reverse directions at the same time. Changing a motors operating direction takes two coil-operated contactors, one for forward, one for reverse. The coil-operated contactors use Unit of competency details UEENEEG108A T6 Troubleshooting three phase induction motor encompassing: circuit diagrams of three phase induction motors; causes of three phase motor faults from supplied symptoms and circuit diagrams; causes of electrical faults in three phase motors, include open and partially open circuit phase winding, short and partially short circuit phase winding, open
