Querying wind generator house building

[chlemagne]

Hello,
I hope to be in the right place.

I have already built my 2ieme VERTICALE wind turbine.

I am about to build my genius.



I have already bought 24 neodim magnets from 45 / 30 / 10 mm.
But I stumble on:
- Diameter of the bobbin threads
- Number of turns
- Usefulness of the shift or not, magnets with respect to the theoretical axis, ie one to the left of the axis on a disc the other on the right.
- Demultiplication; it seems that NO
- I do not want to take my head with inverter and all the bastringue. I only want to power an electrical resistance. (An 2000watts convector or at worst the cumulus)
- Should I go out in "sorting" in this case. If not, how to wind or what to do?

Note: Please do not use too much technical abbreviation that I can understand everything.

If a good soul passed by

thanks in advance

Oh, I can not see the photo I uploaded

She must be in my gallery. But where ?

[Forhorse]

How powerful is your wind turbine, even theoretically?
What speed of rotation?
If it is to power a resistance, no matter whether it is mono or tri or polyphase, since at worst you put a bridge rectifier output.
But if it is to feed a convector or a cumulus, it is necessary to leave either the 230V alternative, or the 230V continues so it begins to be serieu.

Hi Forhorse,
Thank you for your answer

Is not a convector an electrical resistance?

C what a bridge rectifier or C how?

I have no idea how powerful my wind turbine is ... it depends on the veeent.
My "eye" model is at: http: //www.windgenkits.com/Tutorials.htm
See my attached photo

They talk about: Wind energy at 30 mph = P = ½ (1,2) (1,1) (13,4) ³ = almost 1600 watts!
But I do not care, if it's 160 watts, my radi should not be cold. NO ?

Note: I note that there is some rider in the audience. I am a very old rider when I was young and beautiful ...

Is not a convector an electrical resistance?

If, but the point that raises forhorseis that if you feed it with too low a voltage, it will hardly heat up.

But I do not care, if it's 160 watts, my radi should not be cold. NO ?

Provided that your generator provides enough voltage to pass the 160W into the heater resistor.

If your generator supplies 12V, your convector will supply 6W (whatever the power generator).
To obtain "only" 100W, you need a voltage of 48V.
For 160W, a voltage of 60V is needed.

Hi Gaston,

Well, what do you recommend?

Must I give birth, transform, alternate?

Or that I only power a flashlight?

Can you "enlighten me".

Thank you

Note: how do you put the photo (of the wind turbine) in the post?

Must I give birth, transform, alternate?

Many solutions :

1) If you want to use the convector or the cumulus resistance "as is", you must increase the voltage.
1.1) Either by modifying the generator
1.2) Either using an external system (a transformer could do the trick if your generator provides single-phase, but an electronic system will usually be more convenient, the simplest in this case being perhaps the inverter that will supply 220V directly compatible with the charges)

2) You can also modify the load: by putting several convector resistances in parallel you can obtain sufficient power while remaining with a low voltage. Warning: the amperage will increase accordingly and it will be necessary to provide cables of large section between the wind turbine and the "convector".

When you edit your post, there is a link "Insert an image or a file on the forum"...

[chlemagne]

We look forward to seeing you!

Do you have any idea of ​​the power of the inverter?
Or does it find it? Computer store ?
And all the questions I ask at the beginning of the job. Diameter, number of turns per coil etc.

Welcome chlemagne.
I suggest you edit your first message and include the photo you ended up posting.

FYI, so that you understand the problem, the power of a resistance can be expressed as follows:
P = U² / R (P: power in watt, U: Voltage in volt, R: resistance in ohm)
So we notice that if we divide the voltage by 2, we divide the power by 4
Which means that a radiator or an 2000W cumulation planned for 230V, will only make 500W in 115V, 87W in 48V and not even 6W in 12V

Using an inverter is not really possible here, unless you find (or manufacture) a very special inverter that is able to adapt to what will provide the wind turbine.
A normal inverter assumes that it has all the power it needs on the primary side, it is usually powered by a battery.
If you directly connect an inverter of this kind to the generator of your wind turbine, and that this one does not turn out strong enough to supply the 2000w that it claims the resistance at the exit of inverter, the output voltage will collapse and the inverter will fail.

So you need a sort of MPPT inverter, able to find out what is the maximum power that can produce the wind turbine and adapt the output voltage to dissipate this power.
I have this kind of project in my boxes, but it's not for tomorrow ...

Otherwise you have to go on the classic wind turbine which charges batteries (12, 24 or 48V) and a normal inverter ... but considering the efficiency of the installation and the price of the material, it will come back expensive in heating, as much to heat at the nuclear
