    Hi everyone I am new to this forum and a novice. All help is appreciated. I want to automatically reverse a reversible 120v AC motor. I would like a delay of 1-2 sec. from off to re-start in the opposite direction. It needs to keep running and reversing until power is removed. Speed control would also be nice. Thanks

    Exactly what type 120vac motor do you want to control? There are many types. What will the motor be driving? A load that will bring it to a stop in less than a second or one that will coast for a while? Many more questions are possible based upon the openness of the original request. As Johnny 5 said, "INPUT, INPUT"

    You are going to need a motor with an electronic or mechanical brake. Even a loaded gearmotor will not stop that fast. A reversing starter may be the answer, but the short run, stop and reverse cycling concerns will be difficult to manage.
