Playing with wind power

[suicideneil]

Ever seen those spinning signs they have outside some shops powered by the wind, they have one word on the back (top) and another on the front (bottom); when the sign spins you see both words together.. (like 'fish & chips') etc. Stick a shaft down the middle and mate that to your motor via the belt drive or whatever you plan to use...

They are shaped basically the same as the turbine you want to use, only in a single molded piece.

ametek 12v motor

this is the motor you want to try and find and use. If you really want to do it right, I mean.

You are talking about those brushed reel to reel motors they used to use back in the dawn of computers? What makes it better than a brushless motor with more powerful magnets and better winding tech? Those are usually used for larger scale windmills aren't they?

Well direct useable 12v power that's not 3 phase like a brushless


very low rpm to achieve 12v.

expect to get between 300-700 watts depending on swept area and wind velocity.

Creating DC from 3 phase power is easy and I don't have to add anymore diodes (to keep from backfeeding the motor) because a 3 phase bridge rectifier already has them built in. I am only looking for about 100-150W this is just testing an idea. I am only dealing with something that is going to be about 16" tall and 12" in diameter. As I recall those Amteks (they have them at the old school electronics parts store around the street) and they are about 6" in diameter and about 10" long. They have a few other sizes as well.

I am looking to produce about 16V and around 8 amps to which would give me about 115W to start off with, and I shouldn't need a regulator to keep the voltage down.

That Last site I have seen before and read with great interest, low tech is good but No body is dealing with these brushless motors. I may pick up an outrunner once I see what kind of V/rpm I can get out of those.
