Hi,

I just published an article on ENGINEERING.COM about the subject of changing the supply frequency to motors.
Article at ENGINEERING.com

It's derivative of a FAQ I wrote here:

Great article!

always thought the sig name "itsmoked" must have had a lot of history behind it...so many ways to let that expensive smoke out...

I guess the electrican's equivalent to the Darwin Award being preceeded by "Here, hold my beer" would be "that oughta work!" closely proceeded by the smoke being let out..

techarmony; Nice to meet you. Welcome to ENg-Tips. Thanks so much for the nice feedback. Like your linked site too.

DanEE; Thanks Dan! Yeah I've let the smoke out a few times. Well.. actually more than a few times. I often used to terminate old equipment with extreme interest!

For a senior project I designed a gizmo that slowly self-destructed vis timed overload failures caused by careful but excessive excursions of the various and many maximum ratings. All while I stood lecturing on the gizmo's features in front of it so I couldn't see what the audience was seeing. It was great sport.

Excellent article, Keith! Not only the content but especially the way you wrote it. That is pretty often the more challenging part to write something technical in a way others can easily understand it.

As A side line issue. I do a lot of work in Africa. A young assistance came to me and informed me that he had worked out how the electricity worked. Basically it was a smoke issue. All the little pipes (wires) moved the smoke around the stores (ICs, Resistors etc) and the heat made the smoke move around in the pipes. If there was a hole and the smoked leaked out!, then it stopped working until you filled the leak with a soldering iron and then heateded it up again to get more smoke to move around the pipes. Go on, prove him wrong.

So, it got to Africa, eventually. Technology transfer at its, eh.. best?
