Scott,
Funny you should ask, I was just thinking about this today.
I'm interested in the schematic/operation of a rotophase unit used to derive three phase power from a single phase service.
They are very common here on irrigation machines. If there is no three phase line nearby it is much cheaper to install a rotophase than run a high voltage line several miles.
thanks for asking,
GJ
I look at most all of the schematics that you post. I don't always post a comment unless I have a specific question. Don't conclude that just because you don't get a lot of feedback or questions that your schematics aren't of value. They are a great educational tool.....keep up the good work.
