ENGEL engine for wind turbine




by papynou » 18/07/11, 17:45

Hello everyone, I already asked the question but I'm still without idea.

here I put you the pictures of the generator, that in thought you

my problem to me and when I expose my wind turbine to the wind it turns without problem and I get 0 40volt more or less it depends on the wind when it has high wind it gives me more voltages,

when I plug in a halogen lamp 5V / 75W my engine brakes and gives me only 1 volt barely.

I think that my generator does not need any excitement, but I want to be sure of it and that's why I come to expose my subjects

my idea to me I think it's very simple,

at the output of the motor connect to a charge controller so as not to send too much voltage to the battery, then the charge controller connected to the 1 battery, then connect my 12v converter to 220v

Motor controller --- ---- --- battery converter

that's it i think

but I have a lot of trouble with my engine

can you help me ???

I also forget to say when I plug my engine live on the battery, my engine runs very slowly !!!!!

do not look, you just discovered that we can not draw power from something that turns without slowing it down.
your 75W lamp draws too much power from your wind turbine which can not provide it in my opinion.
just give the dimensions of your windmill to see?

We should put all the clear encrypted info on this system to know, but taking energy from a wind turbine slows it down !!

The engine serves as a bad quality dynamo with poor efficiency ?????, ???

just with the dimension info of the wind turbine we can already say this:

P = 0.5 Cp r S v3

for a wind of 36km / h (10m / s) and with a coef of power of 0.3 (for a wind turbine amateur, it is already good)
so we would have about P at 350W

it is only the potentially recoverable mechanical power.

then the engine which has a nominal speed of 3000tr / mn will have a poor yield at slow speed and therefore surely not more than a few recoverable watts.

good for me I managed to shoot 5v, with a wind from 25 to 30 km

only I asked myself a question there is charge controller that varies from 99 € 300 € to regulate the load of an engine
the other day I saw a picture on the internet of a guy who was recovering a charge controller of an alternator and he tinker on a DC engine like mine, do you know if this kind of regulator works on my type of engine
ps: the regulator had no brooms !!!!
