custom Alternator/generator design help

[avr3]

hi guys,

i am biulding my elternator from scratch.

using  24 N50 2"x1"x.05 sitting flat on a 20" disc facing the coils

coils i am using 22 14AWG coils, still not sure how to come about the coil winding, some say 45 and others say  more or less...

any way i am looking for 12volt to charge batteries and my RPM at 200 kick in

coils have no core.  or should i put a core in them?. note that the magnets are on one side of the coils not both.

so how should my windings be?? at 200rpm start to produce ..

thanks

for the help.

Hi, there is lots of useful information on this page

http://www.scoraigwind.com/

Alternatively look for stuff made by hugh piggot. I have a complete manual that walks you through all of the construction steps that I downloaded, I cant remember where I found it though. Its called "construction of a PWA" or something along those lines.

That is great info, but i am building one stator and only one rotor facing each other using the material i mentioned above.

All i am asking the gurus is waht to recommend for coil AWG and how many winds or how to test it, do i make many different number of winds?!! And test each one of them? But test what exactly..that is when i am kinda los!!..

So keep the help coming...thanks
