Hello

A link that may interest you if you wish to use the alternator and its existing induction

http://pagesperso-orange.fr/ebonys/page ... ateurs.htm

Car batteries are not really suitable for use in autonomy, they do not tolerate prolonged discharges.
However, they can very well be used for tests.
I recommend the recovery at first to avoid investing unnecessarily.

I'm starting to think that I should have done a mechanical CAP! (anyway I have never practiced in my field of study! like many students elsewhere)

that would at least allow me to recycle the old box lying around in my garage, instead of using it as a shelf!

in view of the construction of my wind farm of course.

well, if i recapitulate, i can use the alternator, probably the transmission belt, i need to find some pinions for rotation, 2 ball bearings (is that in my case?) a battery to make tests ! and what else?

Hi guys,

a powerful engine drives the alternator and charges the battery which is used mainly for starting: nothing to do with the force of the wind supposed to charge batteries which will be used for a long time!

the alternator delivers at 6000 rpm, engine at 2000 rpm with pulley multiplied by 3, and when it starts, it literally freezes to produce electricity, the engine drives it but the wind turbine freezes. .

therefore: unsuitable.
either modify the alternator (rewind) or change the engine.
there are sites to order your suitable generator.

chance your old crate can be used to make electricity and hot water, if it's a diesel you can even run it with oil, recover as long as you do, here is the field of possibilities ;-)

Hazardin,
If you manage to make a wind turbine on your own, which makes electricity profitably, I send you to Alsace, 6 Chimay blue (to drink with a good cheese), plus Belgian pralines.
It’s not mockery. I am already positively surprised that you are considering the project., And push pin, you are amazing, you are not afraid of anything, it seems. :D
PS, you have the right to take all the information you want on the net, as well as receive gear.
Between us, it is doable. :D , and I always keep my promises.

Finally I see that I'm going all over the place or that I don't understand much ...

Basically apart from rewinding my alternator, can't I expect anything from it?

I realize there are a lot of things I don't understand, so I'm going to ask you some questions.

For how much € I can hope to find a 400 watt wind turbine with battery and 24/230 converter? or a ready made one that I just don't have to go up to my house.

Would it be cheaper to just find the generator and make the mast alone?

Do you have a site that will have wind turbines in stock. The problem and that I find that the investment is quite heavy, 500 € for a 400 W on ebay ...

without counting the mast, the installation, etc ...

no your alternator without rewinding it you will not have much of it.
but any (other) electric motor can be transformed into a generator, with a few modifications. for that there are guides to download from mini eole on the link I gave. I recommend direct current generators ;-)

the regulator you can also weld it yourself but for low powers, otherwise it will be necessary to buy it.

I also recommend direct use in 12V and the use of 12V devices. the converters have a low efficiency except with high power use, otherwise they cost horribly expensive, that's how it is. some are lucky enough to recover ...

for good stuff there are:

The happy medium, I would keep you informed of my work, but before that, I finished my solar oven, OK, by the way, I would actually need information, and I keep this post in my favorites!

I also think that I would contact you on skype at this time, but before I dismantle my car, I have to make some shelves, otherwise, where will I put my mess!

but I would rethink your proposal for chimay and chocolates!

I just recovered (long live the economy: p) a ford diesel escort alternator (seems that it is a little more powerful than petrol :) ) For my wind turbine.

For the rest I think to buy car batteries, I saw 30 and it did not look too bad ....

For the beginning of the tests I would have to fix my drill to this alternator to see how much watt it could give me. But there are three plugs on the alternator, once I have calculated it, will it be the plugs that I should connect to the battery?

And for the rest I will start with a horizontal axis wind turbine I think that at the blades it will be easier to achieve right?

It is only to power bulbs for the beginning, maybe later I would make a second one in order to be able to charge my laptop, unless it is suitable but for that I need 230 ....

Hi my dear, I wonder if you read the links we send you?
I honestly recognized that electricity was not my strong point (at this level I have no experience) and that you would have more info from the "old" (synonymous with "connoisseurs")

I realize that the amount of information given to you is immense!
And, I would be remiss to discourage you, but I believe that you absolutely must realize that what you propose to do, is not an easy task ...

With my best encouragement, however, Lietseu :P

I'm back on the post!

My solar oven will be offered 4 beautiful mirrors next month, while waiting, I throw myself into the wind!

for my 1st tests, and to understand how it all works, I will start with the vertical model, based on the recycling of my daughter's bike (she has her birthday tomorrow and receives a new one from her grandparents !!! hahaha! he won't hang around that long!) I don't think I can generate a lot of electricity from that, but you have to start with something. Indeed, as I said above, I am neither a mechanic nor an electrician, and my lessons are over 15 years old and 5 moves (they are probably lost and forgotten !!!)

So I'm going to ask a number of questions that you will no doubt find silly, and I thank you in advance for your patience (I don't want to sink in completely, but I remind you that I'm blonde !!!!)

let's do, therefore, simple !!

here is a diagram found on the site that I named above:

http://nos-systeme-d.skynetblogs.be/category/1092944/1/Bricolages

first thing the top wheel and the bottom wheel do not seem to be moving. But the vertical mast, and the wing seems to have to turn in the support constituted by the 2 wheels. do you agree

the large diameter pulley also seems to be attached to the vertical axis, is this correct?
