How do you change rotation on a Century AC motor?

Answer 1

There are two alternate methods depending on whether the motor is single phase or three phase. On a single phase motor, reverse either the start winding coil lead or the run winding coil lead but not both. This action will reverse the motor's rotation. On a three phase motor, interchanging any two of the three coil leads will reverse the motor's rotation.

Answer 2

On a three phase motor reverse any two feed wires that come from the starter. This should be done in the motor junction box. By doing it in the junction box it maintains the three phase colour coding of the building system.
