So preliminary results show that a repelling {1}double density single rotor, dual stator{/1} setup is indeed a dead end and quite frankly a bit of a foolhardy idea to begin with
.
I can only get a few winds in a coil at best before the coil gets so tall (2 maybe 3 layers only) the field already drops to unusable values.
So finally I can close the books on that concept.
Now it is still the question "to stack coils or not to stack coils".
But I am leaning against it because although I have not yet demonstrated it I am not sure what the magnetic field in the coils will do when they are tilted diagonally slightly. I can only imagine it will not benefit the interaction between that field and the magnets.
Another, perhaps far more important reason not to stack coils. One that I have demonstrated already is that with having coils stack then heat dissipation rates drop to near zero. Ok truth be told I have not really sunk my teeth into that problem yet to see if I can fix that.
Anyway. I can generate around 1.17vAC at around 3.8Hz with a single stacked coil pair when each coil in that pair has 50 winds (I am ignoring
coil{2}wire{/2} size for now).
And theoretically we can have 48 of those stacked pairs per phase making for around 56vAC at 3.8Hz. In practise I will need some empty coil slots at every stator segment else not be able to (de)install it in a modular fashion.
For traditionally spaced coils we can have 24 coils per phase. But the good thing about the coil shape in this scenario is that it can be wider. Maybe even enough more wide to compensate for the extra winds needed to be able to reach around 2.1vAC per coil at 3.8Hz.
And then of course all the added benefit mentioned earlier.
reporting back once I managed to figure out how much winds that is.
