coil resistance

[electrondad1]

 instead of using heavywire (14awg+) or multi strand ( 22+22 ) to form a big fat coil , i was wondering if i could could spin multiple coils in concentric circles then wire them in parallel to form a large coil with low resistance.any thoughts from any one?

hey!  

that method which you describe would work perfectly fine.

have fun!

  Sounds doable . The thing that is a constant is the you have tight clearances and also mass/surface area at right angle to the flux flow will dictate the configuration of your coils . Not much help for you but that leads to my opinion I think  haveing multiple coils of smaller gage wire to scoop up the same amperage as larger gage will leave you crowding the stator .  When you have the circuits in place the added current carrying capability of larger gage wire  will help the stator take more abuse than the multiple smaller gage coils .

If you wind concetric coils they will have slightly different voltages and waveforms.  You will get current circulating between these coils and this will sap some power.  I may not matter too much in strong winds but it will sap power in low wind and reduce startup efficiency.

when i built this big stator--i thought i might try putting some fine wire coils in the holes of the big coils..

it worked but it robbed power from the big coils--so i ended  up with about the same amount of power output..so what your saying is you want to stack your coils..

may work, but it might have a canselation effect, then again it may not,sence

all coils will fire at once.....let us know what happens..

wow, there are big fish in this pond. thank you all.the inter-coil leakage at slow speed is troublesome as i have opted for a verticle axis design.  i think i'll stack the coils like pancakes. uniform no. of turns / uniform resistance. maximum grunt. and i can make use of all this fine wire.the wind was up last night, across(georgian bay) 300 miles of open water. like a freight train in the trees. i've got to get busy, thanks again.
