please help ghurd or anyone about axial flux

[awk]

 
    if it is 200RPM then with 10mm airgap i will easily get 2.5v

  if i get 2.5v from one coil then what configuration do i use to get 12v system.

[ghurd]

IF you want 12V from a 12 pole, 9 coil, 3 phase Star ("wye") you want 2V per coil when the air gap is properly set, and the RPM matches your blade requirements.

All of this is interconnected to each other.  And all of it is a variable.
So far you have none of the variables fixed.
The test coil in a greatly improperly adjusted air gap leaves nothing but more guesses.

 if i need delta wiring what voltage should i have in one coil.

My suggestion is to double the magnets by stacking them, Then your generator would be more properly designed to do what you want it to do. It's really difficult to keep trying to make suggestions on improvements when the machine has not got enough magnet.

Hi awk,

 this first pic is one of my coils edge on.
I made these with a pretty crude coil winder .

I made these by applying polyester resin , as i wound them.
And taking the appropriate precautions as to not let the resin stick to the winder , by using wax or a crayon works well.



The second pic is another coil , with a view of the face.




If you were to drop your pole outer diameter to 21 cm  in diameter , that will bring everything into sync.

and your machine will function better

This last photo is how it should look if you make your coil holes equal to the distance between magnets , like i do.



I saw your video , you need to eliminate the wobble ! it could be catastrophic just turning it by hand.

Dont forget the coil outer diameter is twice the magnet dia,

[awk]

if i cut my rotor dia to 21cm my output will be de decrease

at first time i am using a 9 inch dia rotor but hugh piggott give me advice me to make a big one.

i like your coil idea i will give it a try.

There is no need to cut the rotors awk , just move the magnets in.

You were talking about the large distance between coils before ?
By moving the magnets in , will cure that , and everything will line up correctly.

 just before i have not make the coil i am only making calculation in my mind but when i put may magnets on my rotor and put my first coil i realize that it is perfect my coil .

more over i have to make my coil thin as 6 to 7 mm because my stator would bi about 10 mm.
