Hello all. I'm new here, and love this site. Our city allows salvaging at the garbage dump, so I have been studying electric circuit board components, magnetism, electrical production, etc then found this site. The dump gave me this small dishwasher LG motor, it has 8 alternating pole magnets on the center turning armature, a 12 coil stator around it in 3 phase, and an 8mm =5/16th? output shaft. A hand spin gave me 20 volts from two wires, so 3 x 20 volts output at 150 rpm? or so. It's label is: LG DBB116Y01 4681ED1004A 310 Vdc 110watt 1.5 amp. So for a starting play toy 12v charger I'm wondering what kind of wind blade & diameter? What about a squirl cage blower type setup on the corner of my house where the wind blows from only one direction where the house compress & accelerates it. So putting the blower in the lea wind vacume side, and the scoop out into the wind should give me max speed & power. Has anybody properly built a double F&P with multi fan blades 1x4 meters each, on the corner of a building to take advantages of the pressure differences? The dump gave me 7 F&P 36 coil motors so far, but I kinda wanted to start with the mini LG motor. I've got 2 arc welders, cutting torch, 14-37 metal lathe, & skills so I don't have to think that small or simple is good. I'm in Alaska & we get 30 mph wind for 3 months in the fall starting October. Any ideas or suggestion as to where to go with this would help? I'm weak for outlandish ideas that just might work.

sounds like you have enough technology.
i put together a vertical squirrel cage last spring .
20"dia. x 48"tall
it uses a home made dual rotor axial flux alternator with ceramic mags.
it runs a couple of LED lights in series with an electrolytic cell.

Thankx 4 reply electrondady1. Did you try setting it up on the corner of a building where the returning blades weren't going against the wind?
The Axial Flux designs I've seen have a closer distance between magnets on the same hub than the magnets on the other hub, so the flux doesn't go through the coils it goes over to the next magnet. Magnetism takes the path of least reluctance (ie. resistance). Have you tried a tube core coil? Tube core= A longer coil with a shorter thin soft iron tube in the middle, attracts flux through the coil, flux traveling through the metal travels on the outside since flux repels itself, then exits through the coils wires to the mag on the other hub/wheel. Minimal metal, and a distance that is shorter than the mag next to it but still a distance from the magnet so clogging is reduced a lot. It's just a new thing I discovered in my magnet to electricity experiments last year. Others probably figured it out before me, but I've never seen it mentioned on internet anywhere. Have you? (anybody seen it?)
Sincerely Bitdog
