well yes i will,
I just guess it takes a lot of time and stuff?
Charge a battery with pc fans?
Hello,
ok I get it, thank you, we can put neodymium magnets I like in this machined rotor: good you need stuff to re-machine it!
a winder will take 300 € to rewind the stator with copper wire, we can do it yourself with the PDF of mini eole, but it's time to take and not to miss, unless you have a special technique?
you have other photos of the project where you are at?

I am surprised by this answer, because for my part I measure 2V by blowing on a PC DC 12V / 0.20A fan.
I may have missed something, because I'm not at all a specialist. But a priori, I measure 2V (the voltmeter is set to 20V).
By cons I do not measure any Amps. Could someone explain to me why?
I find that the idea of making a wind turbine in the wall of PC ventilo recovered to recharge a battery is very good. But I would like to make sure that in practice it is viable.
Thank you

You can't measure much.
The motor is a brushless with integrated electronic control card. You do not have direct access to the windings. https://fr.wikipedia.org/wiki/Moteur_sa ... tionnement
If you want to make it an alternator, you must recover the current directly at the terminals of the windings and go through rectifier bridges and a battery charge control electronics.
For a result probably disappointing, because the pale are not suitable as Christophe had said.
