Axial Flux Wind Turbine

24 pole, 3 phase alternator. 18 coils of #20 wire 80 turns each, 6 coils in each phase connected in series, then wired 3 phases in star config. Put out lethal voltages at a very low rpm. Using N45 2" x 1" x 1/2" Neo Mags, two discs of 24 each attracting each other through coils. I need to know what the number of turns would be for #13 wire, same configuration for charging batteries.

Shape of coil windings on a axial flux generator

I am making a axial flux wind turbine. I have watched many tuts on YT and researched alot on the net, but there is one thing that is confusing regarding the coil windings: Does the gap in the middle of the coil have to be the size of the magnet? many people do this and many don't, from a engineering perspective, which is better, my understanding is that it is best to make the gap as small as possible, that way you use up most of the magnetic flux. What is the best approach and why?

How do i determine the number of coil winding/size in a axial flux generator ?

I am building a axial flux wind turbine, i have built a small one, now want to move onto a bigger one. but i couldn't find any information on how to calculate the size of coils for the required power output. example i want to make a 48v 5kw generator, how would i calculate how many turns is required, the wire thickness, how many coils per phase. can someone please explaining the process in determining all this?all the resorces online just give me numbers, example 72 turns of 1mm wire to get 48v, they dont tell me how to calculate it myself for different voltages or different power power output.any help would be appreciated thank you

Reuse old motor from cement mixer for building coils in the axial flux alternator for diy project 1kw wind turbine? TIA

 The coils in the alternator are meant to be 14 gauge enameled wire, does anyboedy know if the wire in other ac motors like the one in a cement mixer use this type of wire? Cheers!
