Motor Conversion

I had this in a old blower that finely bit the dust.
Looked easy to play with so I though I would try to make something of it.
Maybe a bigger LED wind mill. I plan to use the same wire that was in it.
Can go smaller if needed.

The magnets are what I had on hand and fit nicely.
They are hot glued in to have a North and South pole.
I ran it at 1400 rpm and wired to one coil gave 2.65 volts. Not great, but something.
I do want to get all I can out of it. Like ever one else, Of course.
I know the rpm's are to high with this set up.
What would be the best way to wire this thing?  
Open for suggestions.

6 coils in there?

Either need 6 magnets (NSNSNS) and single phase,
or separate it out to 3-ph and use 4 magnets (a lot less cogging) like I did in my old box fan post.

Similar (4 mags, 6 coils), but a furnace blower  http://www.otherpower.com/images/scimages/2050/Stuck.jpg

Thanks Ghurd
I will look at the links.

Those magnets.  Are they the old #29s?
That' is what is in the furnace blower in the pic.  I cut them in half lengthwise with HF Dremmel-type diamond cutting wheels (ugh! Not fun) for NSNS.
Reconnected the coils like in the box fan.
Pretty sure it was good for 100W easy enough.
Never put it together solid enough for a high speed test because it has bushings.

I'm not sure about the magnets. 29's They came out of an old trolling motor. I think.

Great links.
Just what I needed.
I will cut mine in half to have four. Should fit good in a new rotor.
Also mine has bushings, not bearings.
Thanks

#29s were from very old HDs.  "#29" was the items otherpower shopping cart part number.  No longer available.
It took a lot of those cutting disks.
