How to reverse the direction of a three-phase induction motor.
Reversing the direction of a three phase Induction Motor is useful in a number of situations.
For example in a electric winch or elvevator (lift), there is a requirement for the motor to reverse.
To reverse a three phase induction motor, swap over any two of the three ‘phase’ connections in the motor terminal connection box.
Warning: Only attempt to do this if you have been trained, as over 400 volts is involved. Also obtain all necessary ‘Permit To Work’ documentation, and the locks and keys, for the isolator ‘lock off’.
