thanks one and all for your input, it is appreciated.
my background runs deep in automotive alternators, and less so air cores although i have
been following them for years.
windpower or rather windgeneration of electrical power is fraught with some interesting challenges.
first one starts with a motor (blade set) that provides power in a non linear fashion,, then you drive it
with an infinitely variable fuel source (the wind) and strive to charge batteries which have another set of variables, and
then use the power in another variable way.
with the link being the generator itself!
seems like empirical data has done more to get the thing to where it is today than any set of equations would ever hope to.
talk about a multivariable equation!
personally i cannot imagine striking out on my own, and setting down to try and design a totally new windgen from the ground up
with nothing more than a pile of questionable variables.
seems far easier to me to just build a copy of what others have done, proven to work, and then learn to live with what power it will provide.
and if it isn't enough, build another one.
i have spent a number of years now researching, and the last couple years testing and developing hd alternators for use in cogeneration
where i have a fixed speed, a linear power source, and exceptionally accurate charge control of the battery bank,, even with all this
working out details or trying to calculate what the results will be when i make a single factor change can be very problematic and drive
one out of the mind some days.
in the next few months i have to complete the main trigenerator and also a small cogen unit, and then i will need to get started on a windgen
for use on my ridge.
at least up there the windspeed is fairly consistent , if there is wind blowing it will almost always be over 10mph up there, so maybe i won't need or care much about low windspeed cutin and power generation.
this forum is populated with some of the most knowledgeable folks on this topic that i know of, and my hat is off to you guys for the shear willpower and effort it has taken to get these machines built to the levels that are common here.
thanks guys
