hi, iam a newbe trying to figure some of this stuff out and wondering if someone can take a look at my pics. to see if iam on the right track. The rotor is 7" with 12-1"x 1"x1/2 magnets,with a 1/2" space between, Dual rotors.

 The stator is 8" with 9 coils, with 1/2" legs and 1" holes.

 I made some test coils from some telephone wire i had laying around with a core of

 .025 and a outside of 0.065. i was able to get 50-55 wrapes in a coil to fit in my

  pattern. Was wondering if i use some #18 (0.040) that i can get maybe 100 or so on them. But i really dont know how many i might need.

  I would like to try to get a 175-200 cut in speed.

  what i would like to use it for is to charge a 12v big 8D gell filled battery that i have, with a 2400watt brutus inverter that i am using to run my light & small tools in the shop. The only problem is iam cheap and dont have a good blade

 to use. The one that i have is 28" fiberglass hub fan off a tractor trailer.

 The blade is really stiff and dont think it will flex at all. I was able to get

 193 rpm with 8mph wind mounted on a shaft one day. A little help from someone

 would be great, before i buy magnet & wire. Also what kind of watts do you think

 that i might get?


                                          thank you,

                                              charles

I looked at your photos, You have 12 magnets on your rotor which looks fine, but you also have 12 coils on your stator,I think you need to remove three of them and use 9 placed accordingly.

thanks shadow, i guess i cant count too good...lol here is the other stator, does the shape of the coil make a difference? also,  

  I know that there should only be 3 wires leading from the stator. so, connect the

 x-y-z together for a star? thanks for your help again.

Yep, Now it looks good. I connected abc together and used xyz as output, but either way should work. Coil shape seems ok, center hole should be slightjy smaller than magnet size. I think you're on your way now!

thanks shadow,

  now i got the mag. size and the stator shape i need to try to guess on what the

  turns should be for a cut-in at 200rpm. I was thinking to try about 60-75 turns

with #16 wire, what do u think? now that i changed the stator with the (right amount of coils) i need to make a different test coil to see how many turns fit in

 that shape. The only wire that i have is #14 (0.064) thanks for your help.
