Hi Dan -- to get three phase from 9 coils, you'll need 12 magnets per magnet rotor. For a tiny turbine, you could go 6 coils and 8 magnets for 3 phase. There...

The problem with the setup you describe is that the distnce between the magnets includes the thickness of the stator casting. the magnatic field decreases...

An axial flux doesn't "cog" until it's spinning fast enough to actually produce energy, so 3 phases works just fine. More phases would just complicate the...
