I like what you did and do. It is always nice to see innovatively thinking persons.

Now my criticism if you don't mind. The wave winding is good to the point that it saves wires (And so saves weight) and also saves resistance counts. However, we have to be very careful as to phasing. Because, it is a wave winding so all the coils are wound as one giant coil spread all over the outer perimeter of the stator backing disc. And so all the magnet poles will have to pass the coils in a more precisely synchronized way. Meaning, you will have to have the same amount of coils against same amount of magnets and spacing would have to be same between magnet poles and coils--more cogging. If these rules not observed, you will lose out pretty large due to waveform cancelling one another between coils obviously. In worst of cases, you might end up having zero volt ! If one pole happens to be North cutting while another pole happens to be south cutting at the same instant, both thethe peak and valley waveform will cancel out one another--Zero output !

And then, a complete closed-loop of a coil is more in efficiency than a half open coil.

It is known that multi phases are better for battery life than a single phase charging. Just imagine, the wave technique would entail longer wires again even though you can still employ the wave technique, just imagine the picture, I need to say no more because you simply would need to have running wires to bridge between coils of same phases.

This is all the negatives I can give you, now you can pleasantly see that I am that devil to ya  :-
