Been thinking on it today....

When the magnet turns on the hall, sending current to the drive coil, the coils polarity is opposing the magnet, same pole. And as the coil field rises over a period of time(dependent on the coil), it will cause a change in the field that is turning the hall on, and causes it to turn off, then the cycle continues..

So, is the rise time of the coil at the same freq as the resonant freq of the coil? Is the singing freq the same as the speedup freq? Close? If so, then this is an easy way to get the coil to go into resonance. It will just happen.  I would say the magnet will adjust the inductance up(lower freq), I believe that is what Luc had shown. And I imagine a bit of freq change with adjustment to the hall position.

And we can definitely say the other coils are loosely coupled(Tesla) to the drive coil. More than I would imagine from reading of it.  ;]

Dont remember, are any of Romeros halls near a drive coil?
Maybe he was doing this with one of the drive coils while the other was a driver. Just thoughts, due to the differences from 1 hall to the other in Romeros config.

I would put some fuses in line on the coils, just in case getting all of them singing may multiply what is happening.  ;]

This IS good stuff. Blew up another 1000µF this time on the output side. Mags, why do I want to have all the coils singing if they are listening already?

Clever thinking again, Mags! Remember he always said that he didn't wanted the halls firing at the same time. Now you understand also, why one of the halls was positioned to the small magnets facing outwards of the rotor. That will give a smaller time to fire. When I was hooking up another driving coil this was destroying the resonance if being pulsed too long! He always said the load cannot be exceeded! It is true if you want to maintain resonance.

Why just listen when you can join the band.  ;]


If they sing, I think the output would be more.

Yep, so true.

Maybe this is the importance of Tesla quenching his sparks.   To stop the continuity across the gap so the resonating object coil doesnt get damped by flowing back through the gap.
