A.C. Motors

10/09/2007 10:18 PM

I have been told that an A.C. motor when spinning clockwise is more an inductive load and when spinning counter-clockwise it becomes a capacitive load.

Is there any truth to this ?

No ways..

I guess you are not a electrical engineer or even engineer.. But still I think it was there in the first year of graduation or even diploma or any engineering certification.

Probably a bizarre misinterpretation of synchronous motor operations. You can adjust the field strength to make the motor run in leading or lagging pf, but that has nothing to do with reversing or not. Sounds like one of those things that was passed on from one electrician to another to another, with each one changing a seemingly insignificant detail until by the time it got to our OP, it had morphed into something completely bogus.

Did anyone else ever play a child's game called Telephone Line or Telegraph where one person in a line says something innocuous to their immediate right such as "The sky is blue" and by the time it passes through 30 kids, the last one hears " My banana is squashed"? Same concept.

None whatsoever.

Thanks guys for smothering this one for me.

It is a blessing to know how and why things work the way they do, we read, learn and share. But when it comes to practical application and implementation we all know that is a whole different ballgame and there is always the unforseen factors that causes the strangest of things to occur .

I always leave some room in my thought train to listen and try to understand the spooky realities of equipment application.

Thanks again.
