Most automotive type gen/alt are rated at 1200w @ 2000rpm. You can never exceed the wattage rating while continuous running. So if you raise the voltage output then you have to derate the current output by the same precentage.
The number of poles determines the frequency output. 4 poles turns at 1800rpm and 2poles turns at 3600rpm for 60cyles/sec

1200w/6v=200amps
1200w/12v=100Amps
I haven't a clue where you got the idea that most automotive generators and alternators are good for 100 & 200amps, but where ever you got it, you need to trash it. Yes, you can find some newer alternators with that kind of capacity, but not a snowballs chance in Hades on that 200a, 6v generator!
Hi Jmor,
I would think approx 98% of the automotive is being charged via alternators for 12v systems. I know that some of the newer 12v generators also will produce to those spec's, so the above is a true statement.
The other 2% would cover your misfigured 6v as well we all know 6v generators are lucky to be rated at 65a or so.
Don't think I've ever read a 6v generator wattage spec so I can't quote those.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
