Shorting coil gives back more power

I was using the positive and negative wave peak for shorting when I tried to run from the capacitor only.
I have also tried what you suggested with the AC SS Relay and at any speed or with different capacitors connected as you suggested the parallel wave is close to the main one and I think that it is normal to be like that.
If I change the value of the capacitor in series with the AC relay then I get the parallel wave at different position or even shifted, I am sure is about resonance.
I have got the best results shorting the wave all the way, multiple times using a 555 circuit and SS DC Relay.
Today I am too tired to do more testing and pictures but I will post more results soon.

Keep shorts top of sine where Voltage node is max and current node is tuned 90 degrees lagging. Use fets or IGBTS for shorting don't use those  SS DC relays they are designed to turn off and on slowly using snubber. Kone and others did all this YEARS ago.

AC SS relays are a 100% no no! They will only switch off the zero points which creates a secondary echo sine wave.

will the shorting cause the caps to eventually fail?  Understanding solid state is the way to go but will these components wear out as well?

I've been going through the posts on this thread and would like to give my two cents on a few things I've noticed. Someone wrote you need N-S arrangement magnets to get a sine wave, well clearly he's never put a scope on a coil pulsed by an all N rotor  .

A few people seem to confuse the flyback kick when a charged coil is let loose with what is being discussed here.

Romerouk, you said that you get acceleration when you short the coil through most of the cycle, I get the same when I do that. This is "normal" with an open coil core, This is actually what the Kromrey generator principle is based on. You wouldn't get this result with a core closed on itself like all traditional transformer cores... I don't know if this is what we want in this application though, as Bolt pointed out.

Anyway, keep up the good work!

Bolt:

Romero described how he connects the SS relay to the coil and also see his post here:

I mention this because below your text means as if Romero had used the SS relay for coil shorting. He wrote he used the output side of the AC SS  parallel with the coil (and he did the shorting with one or two reeds) and he did not control the AC SS at all at its input pins.
And he used the DC SS to discharge the puffer capacitor once during one revolution. It surely does this task nicely. See here:

I thought this needs to be clarified so that other readers who are not fully aware of the exact setup should not get wrong info.
