Resonance.
@Cosmicfarmer,
This is a very exciting miniature project sized just right for a kitchen bread board.
The charge shot up about a tenth of a volt, that's ten up clicks on the hundred's scale if your setting's at that level. Then the charge rate slowed. I don't know how to account for this. I didn't try to reposition the magnet over the pulse coil to get the chargeing to recontinue, because it was an after thought. It may have restarted the charging. Nothing like that kind of charge recovery took place when measured against the other kinds of stops I tried.
I slipped a bearing and had to saw the carbon rod axel out to reglue it. It occured to me that, rather then wind directly around the core, it might be better to wrap an outer sleeve, and nest the spinner tube inside to assist the servicing of the magnet bearings. My scaled up version will assemble this way. It's an approach to consider because it would help to pull the axel in the event a bearing came unglued. I'm re-fashioning slide grooves inside to push the axel and magnet back into position right now. I got it to squeeze in and reseat nicely, I don't know if it's the best way. Two PVC rings attached by two narrow and sturdy axel bearing struts for a sleeve, or just a PVC section with the sides cut out, and the magnet and axel seated for an insert.
Also, I'm building the Magnetman12003's "BediniDavro" loop back to source circuit right now, with the relay coil, to test on the bifilar motor wrap.
Boca has three kinds of all ceramic bearings in the same dimension, one with two bearing balls side to side. The size and balance of the tube magnets determine how sturdy a bearing should be. The other variety has a closed casing. These bearings are very expensive, but much simpler then a Maglev Axel to achieve super high r.p.m.'s. They purr! Keep me updated on your build. This project was the most exciting of all so far for me.
I think Reed Switch resonance was the the key to my first sucessfull high speed runs.
