I see where you're coming from, George. IMHO, it not something worth experimenting with. The winding of a stator isn't to difficult (just extremely tedious), but I look at it like this. The voltage/current tradeoff is set by the number of wire turns. The voltage is limited to a nominal 12V in a 12V system. Marketers don't get anything for declaring that their stator will put out 24V. The only way to win is to get more current. Everyone is will be studying how to wrap the stator to get the most current at 12V. The engineers that design these things are smarter than me about these things, and their living wage depends on them doing a good job. So, I let them do the tedious job of winding my stator, and I'll just believe them when they say it is designed to push 35 amps worth of electrons. -- http://www.ernest.isa-geek.org --------------020807070705020002000704 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 8bit George Lendich wrote:

Ernest,

There has been discussion on other sites of making one specifically for rotary Aviation use. The Amperage is the result of the number of windings and size of wire and number of poles, from what was discussed. On some stators there are poles serve a separate function but can't remember what they did.

I was hoping to stimulate some discussion between parties with a greater knowledge than mine, I'm afraid I'm electrically challenged - but I'm working on trying to improve my knowledge.

From my part, and at this point in time I am just curious.
