@Maxime124 A car alternator will not work due to the fact that instead of having a permanent magnet on the stator, it has electromagnetic coils (EMC's). It relies on the power from the car battery to create a magnetic field with the EMC's. The voltage regulator regulates power to these coils which in turn regulates how much power is generated. No power to the coils on the stator means that no power will be generated. So a car alternator will only work if you replace those coils with magnets.

Needs more blades

What insane intro? To put people off?

thank god, i thought i was the only one who noticed it being hidden behind a wall. might as well put it inside then. it was probably spinning too fast with no load on it. great design. it looks like a stepper from a scanner or printer would be too small. try looking for an old washer or other appliances with motors in them. experiment.

put a motor on it. ItL go fast then!!!!!

kinda defeats the purpose of making it 6 feet high if only 3 feet of it is available to catch the wind....move it out of the little cubby ya got it hiding in

Did you use an alternator allready? I build also something like this (check my profile) and I'm wondering if a car alternator will work.

I hope where ever you moved it, it was from BEHIND THE BOARDS!

good job

I made bigger flaps from an old plastic-carport, looks funny.
Hmm, do an update-video, if its windy outside.

Hi,
I'm building my first VAWT now and have hit a problem. What alternator to use? I've got no money to spend on a decent one, so I've been looking around for old machines which have stepper motors or alternators and solenoids.
What can you recommend? My project is small, so something which works on a low rpm would be ideal.
Thanks for any suggestions :)

Hi JamboyStu,
you are welcome.
Search for stepper motor basics on Google, there is a site reuk.... there are some great informations abot stepper motors, i built my bridgerectifier for my harvested stepper-motors with that information.
A caralternator is useless, if you not rewind the coils.
Best regards stefan
