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

KejiKeji Registered Users Posts: 3
i am building a axial flux wind turbine, watched a few yt video and read some articles. 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 10kw 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

    Perhaps one or more of these links can help (we are not a bit DIY wind forum):

    10KW is a pretty large machine, but maybe you are not expecting 10kw worth of wind?   When you do get the wind, you will need a huge dump load for that.

    Hi bill thanks for the references, 
    i had a look at them they all seem good, otherwind.com being the best but i cannot register as it would not allow me to register, would you have any idea about that, thanks

    hi
    the 10kw was used as a example (but i am heading in that direction) as i want to do the calculations for myself, every article i came across just gives me the number of turns for a 48/12v system and the wire size to use, with no explanation.

    I have never used/communicated with the Otherpower forum... Just try the registration link/process. Sometimes, it may take a day or two for some forums if they require a moderator to approve the application:
