haha, sure is.
You had better make *damn sure* of the lowest AC frequency that
alternator will produce - even during engine cranking - or any attached
transformer will magnetically saturate and draw * huge* current from the
thing.
Didn't think of that, although I suppose you gathered that.
I'm really only interested (at the moment)in seeing what sort of power i get
out of a 3 phase alternator when using only 2 phases compared to it's
normal setup.
I'd love to experiment with toroidal core windings if it is not too
expensive excersise. I imagine it may be too complicated.
I managed to get a regulator circuit working for the thing using a couple of
old PC motherboards for parts. I sort of understand how it works but have a
feeling (from my limited education on the subject) that it needs some
refinements. I had to replace parts until it regulated at the voltage I
wanted and think it relys totaly on the beta value of the 1 transistor in it
and that this may pose a problem as it heats up. If I can work out the
component symbols to draw a circuit diagram of this I'm sure someone here
could point out any likely problems at a glance.
So phill,
can I get a core and start winding or is it more difficult than that?
thanks
