Querying wind generator house building

[dedeleco]

The 3 wires give three-phase (alternator):
http://fr.wikipedia.org/wiki/Courant_triphas%C3%A9
and therefore
either connect 3 identical resistors to each other in the round if the heater has 3 identical resistors (or 3 identical devices)
either rectify with 3 diodes powerful enough to have direct current:
http://fr.wikiversity.org/wiki/Redresse ... phas%C3%A9
http://www.google.fr/search?num=100&hl= ... 0&aql=&oq=
take diodes for current 5A or 3A or more in strong winds and depending on the voltage.

Watch by hand the tension that your magnets will give on your coils (number of turns of the coil and section) at the speed where the wind turns:
http://fr.wikipedia.org/wiki/Induction_ ... C3%A9tique
http://fr.wikipedia.org/wiki/Alternateur
because it fixes the number of turns for the desired tension at known speed !!
Otherwise for the maximum of current there is interest in putting the wire as large as possible for the space available for the coils (and the price of copper), because we lose less energy in the resistance of the wires of the alternator. .

Hi Obelix,
Excuse me for insisting: what do I do with my 3rd son?
Re excuse my reduction is 3.
I come back to 60 turns?
Yes, your reason for the appliance; I did not think.

thank you for your answers

Bjr Germany,

For your three wires and to balance your generator it will be mandatory to rectify the voltage with a bridge of 6 diodes. You will then have something that you can transform into what you want.

The diodes will have to be powerful enough of the order of 20 A and 100Volts of tension, it is rather large!

With a multiplication by 3 the coils of 60 turns should be sufficient .....

Thank you for your documentation and explanations.

You will not have bothered for nothing.

Note: It is not impossible that I will come back to you, if you wish, as I progress.

thanks again

Where I had not seen this little drawing!
I hope you are not the author, because whoever drew it understood nothing about the three-phase! (placement of V1, V2 and V3 ...)

What do you see as the problem with this diagram?

This is the way to rectify in full alternation for the three-phase!

The only problem is v1, v2, v3 which is directly coupled to what seems to be the mass but apart from that.

No problem in the rectifier.

It is precisely the rating of the tensions that shock me.
it would be fair if the alternator is star-coupled with the midpoint to earth / ground, but this is not the use.
Even when coupled in a star, we leave this midpoint "in the air", so there is no voltage with respect to ground.
And I'm not even talking about the case of a triangle coupling.
In short, the arrows for rating the tensions are misplaced.

Well, this is to keep you "in the know"

I finished my homemade generator made from two discs of 12 neodim magnets (30x25) and 9 coils of 55 turns of 1.5mm cast in resin. The whole thing turns by the wind turbine (see photo at the beginning) with a reduction of 3 per bicycle chain.

I did not try in "real" but by pushing by hand ... lack of wind.

I only get 3 volts between phases and light a 12 volts "auto" lamp.

I do not hide from you that I am very disappointed but in the rereading of different posts on the site, I may not be far from the truth ...

Disappointing, disappointing !!!

Well, it's better to try to make a wind turbine than to say bad things about your neighbor. spas?

[dedeleco]

12 magnets and 9 coils at what speed of rotation on what diameter ???

I remember that to make 50 hertz you needed a lot more magnets on a much larger diameter at a low speed of rotation, on another post.

So in the vague vagueness, it's not surprising not to have dreams

Spin quickly and you'll have a lot more tension.

with a reduction of 3 per bicycle chain.

not clear, because it is gear reduction of the wind turbine speed so that the generator rotates more slowly than the wind turbine or the reverse gear reduction between the generator towards the wind turbine so that the generator rotates faster ??? ??

The vagueness and lack of rigor leads to unsatisfactory vague results.

Hi Dedeleco,

Thank you for your answer
As for magnets and coils, I pumped on:
http://www.windgenkits.com/Tutorials.htm#.
i.e. 1.20 ml in diameter x 1.20 ml in height
For the moment, I pushed by hand, for lack of wind

For a reduction, it is obvious that it is the rotor that rotates faster than the wind turbine. I am not spoiled.

[dedeleco]

The pdf gives 12 volts at 2 turns per second ??
Is this the case at this speed of rotation ??
The ultra-short answers are not clear and therefore we don't get tired anymore !!
