Stator and Rotor how to make help needed!

[infringer]

VOLTAGE I am going for 12v No Doubt there seems like the way to go.

Barrels will be 2 high and I will have to find some hubs so 12 or 13" seems like the way to go for now.

3 barrels would be great sure but 2 is what I can get for now so I will plan for 2...

hrmmm 13gauge coil here...

Not to go off topic here but those of you reading along interested in micro turbines you can use your computer case fans and some of that plastic packaging and some wood screws wire all your fans in a series and generate some power this was a little side test I did.

EDIT:
What did you use to anchor your magnets in place super glue or epoxy?

Errr I should not have messed with my mags tonite but I was curious I noticed there was a hole in them so I dunno if those were the ones I got I actually bought these mags a while ago and I started pulling them apart and snap the force friggin busted the mag into pieces man these are some tough bastards lol!

NOTE: They may only have 81lbs pull force not 100% sure but I'm thinking of purchasing all new mags and saving these for another project down the line seeing as how I may need the extra pull  in order to generate some good power...

So how many mags? Where is the cheapest source? And what pull rating do you think is needed for it to put out some good wattage at lower speeds? Knowing that I broke one already thats possibly only 81lbs of pull I suppose I should order one or two extra in the event that I should break one again but it was either the mag or my finger so I chose the mag... Just breaking the mag tought me an important lesson though hehe I've ordered everything so far from magnet4less.com maybe they are cheaper somewhere else for all I know also is the length important ? Would one 4" in length allow for larger coils and more power output then one that is 2" long at the same pull force?

If you look off to the left there is the magnet that smashed into pieces definately will have to order more...

But maybe I'll just get all new seeing as how I will likely not be purchasing that tower setup I just aint into setting up a tower so to speak on a rental property the barrel turbine will do though I can always take that with me I have a feeling the shelf life of the barrels will be rather good being plastic.

And for documentation purposes a saloon door with a spring with coils and mags might not be a bad idea either to try ... Errr sorry for going off topic a little but I will jot down ideas like this during this whole project do not let them detour you in any way!

Alright Infringer!
  Finally, got a voltage to work with! Soooo, 12v, two barrels max.. In that case buy 24 of the 1x2x1/2" epoxy coated mags and mount them
N-S-N-S-N-S on the brake rotors with a little dab of epoxy under each one. Prepare the rotors first by sanding with some 80 grit and wiping
down with a clean rag and a little acetone. After mounting the mags (I hope you drew up and used a template) give the rotors at least two
coats of your favorite color Rustoleum. Before you even start though, you MUST align the brake rotors with each other based on their lug
holes and file a little notch on both of their outside perimeters at the same time so your mags will align properly- very important to do this
accurately and carefully. When all is said and done, your arrangement should be like this-

    rotorotorotorotorotor
    N S N S N S N S N
  statorstatorstatorstator
    S N S N S N S N S
    rotorotorotorotorotor

Note to Michelinho- Earlier in this thread you suggested that Infringer mount the mags with all of the same polarity facing one direction-
AAHHH! NNNOOOO!!! While this might work for a window motor or other more esoteric applications that I have seen here on this board
it definitely will not work on an axial flux alternator, plain and simple.

The mags you have now (if you bought some more for a complete set of 24) would be great for a larger machine, but have a little too
much ass for a two barrel 12v vawt.
  Since you're going with a vawt (somewhat slower) and 13ga. wire, then you will be in the neighborhood of about 65-70 turns per coil.

Before we go too wild do you have any idea what a rough output will be "LOW ESTIMATE" in say a 12mph wind watts?

I would say aside from the 2007 wind maps going by just normal observation that is my average wind speed not the 14mph that they say on the wind map...

I wanna have a decent wattage at this speed if I need bigger mags rotors or more barrels so be it...

I guess 400watts at 12mph wind would be ideal but I will settle for less if need be I will continue to work at the build aspect to fit the power production goal but I would prefer to know what I need before building you are a great help thus far man just hang in there with me and help me settle on a design after we are done I plan on creating a materials listing and a guide to follow.

Good power production at a cheap price that is the goal here time for the DIY guy to have the edge over the market.

WARNING: THIS IS NOT A SCALE DRAWING JUST A ROUGH SKETCH THE BLUE BOXES ARE THE BARREL HALVES AND THE GREEN LINE IS THE GRASSY GROUND!

Below is a picture of how I thought about this design before I knew a thing about savonious...
Things to note:
- The Pole is stationary
- The stator is stationary
- There are two generators on this unit one on top and one on the bottom..
- The barrels are connected to the rotor and spin around the pole
- The through bolts hold the barrel in place from bouncing up and down  and keep the unit solid while it spins.
- The two barrels sets are connected in the middle and will also need a bearing there as well.

Here is how I envisioned it to work I do not fully understand the mechanics of operation of your design but it appears as if the turbine will not only have to spin the rotor but it will have to spin a pole as well I am just trying to clarify the design principal pleas best describe the operation of your design maybe I'm used to lame schematics like the one I drew I dunno but here was my thought...

Enjoy time for a little spring cleaning I will check back now and then for rx's.

AHHH HA your stator will be between two rotors on the bottom even less to turn I think errr well in your design you will have to turn the pole as well as the rotor which will take more effort then turning two rotors I think will it not?

I dunno I think having two rotors will result in a lower startup speed and keep things more mechanically sound.

Just suggestions I value your input on these thoughts...
