I have a 24" steel disk that I am using for an axial-flux genny. It has 40 (2" x 3/4" x 1/4") neos on it. I was planning on doing it 3 phase, with 30 coils. What gauge wire would you recomend? (I was thinking #18AWG)? My goal for the genny is to acheive 20KW at less than 400RPM. I know I may need to double up the mags, or add another set of magnets and coils to the other side of the rotor to acheive the 20KW. Also, have you guys heard anything bad about using epoxy to adhere the mags to the rotor? I will have pictures up soon.
