wiring a diy stator ?

Hello, I making a wind generator but I want to know what wire gauge to use to get high amps, and how to reduce cogging. Also want to know if I can make my wire coils with double wires, if can, can I connect one in the delta config. and the other in star,  want to know if it will work. It is a 9coil stator and 12 magnets. Thank you.

That's quite a big question there. Companies spend millions in R&D trying to figure that out. The thicker the wire is the larger your coil has to be and the less voltage your able to produce. But you get increased amperage. The thinner the wire the more turns you can pack into a small space and keep it all as close to the magnets as possible. Thus producing more voltage. I guess the question to ask you is how large are your magnets and how much room do you have to work with here? How much voltage and current are you looking to produce? You also gotta take into account the overall magnetic flux that needs to be cut though here. If your coils are too large you'll need a lot of wind pressure to get your turbine moving.

If you make each coil with a pair of wires your reducing the voltage and current produced in that coil. Are you trying to do this as an experiment to see which configuration will produce better? If so your better off making 2 separate stators. If not than pick one configuration and stick with it. I think the star is more common amoung DIY stators.

How big is your motor? Maybe it would be easier to go to an electric motor repair shop.

To reduce cogging put a one stator slot rotation over the frame length.

And this most excellent instructable will introduce you to wire winding slot insulation to topsticks.

WOW. That Instructable is a real reference work. What an amazing piece of writing.

Axial flux generators are reputed to offer the least cogging, probably at the expense of a poorer magnetic circuit
