@nul-points
is it coincidence that Romero called collector that toroid?

@Mondrasek . I can see a rough pattern in your data . It will not be easy to get exact readings as the proximity of your hands and body will effect the results . I am an "A" class radio ham , but am more of a practical guy than a theory man . All my life I have had a powerful short term photographic memory which enabled me to pass exams . But ask me a week later and most of it had gone .If you want mathematical answers there are far better guys on here to give you answers  . As regards my late friend Pete [ not Bill] he was not a computer man , but he was the best mechanic and welder I ever met . It was he who welded my first pyramid frame . We met at primary school and I still miss him every day after two years .. Can you confirm that your measurements are in millimetres , and you are cutting 20 cms off at a time .
   @Nul Points . Yes , the RF alternator could be very relevant here . I had to laugh though , because Pete and I tried to make one back in the 1960s out of a high speed electric motor and a bicycle 12 pole hub dynamo . The dynamo bearings seized , and it disappeared through the shed wall... It would never have had very good frequency stability with a belt drive though .
    Another thing to try is make a RF sniffer [google it] This is just a microamp meter and a germanium diode used to detect radio transmissions . You could also try an antenna matching network between the antenna and the machine to achieve a perfect match , but this would not help you find the frequency . Google Pi network .

Irrelevant now what is the i/p ration .99. I see you drove the questions so that the conclusion is obvious, no OU, YET!!!

I need help here. With your skills I would love to "know" why I have those spikes. Do you? There is nothing special on the circuit or the output circuit. Just magnets passing by a coil with bias magnets behind. One should NEVER have those spikes there, correct?

Now it would be a great moment for us to speculate what could be the reason behind those spikes and ways to test the hypothesis speculated. I still have the motor so good timing now.

Fausto.

Remove the FWBR and capacitor, and drive the load bulb directly off the coils. I'm quite certain your spikes will disappear.

I suspect what's causing those spikes is a tiny bit of inductive kickback from the coils, caused by the imperfect switching of the FWBR diodes. The diodes don't switch on and off instantly so there are small breaks in the coil current, and we know how a coil responds when the current is interrupted.

Regarding my curiosity about the INPUT power for both cases, I wasn't driving toward a Pout/Pin computation; what I'm interested in is knowing if the INPUT power is proportionally higher in the case where the bias magnets are applied compared to without them. Determining this is important for understanding certain things.

Thank you for the answer. I see you looking for patterns too. So, if I put than 10 more diodes on the FWBR would I see more spikes or higher voltage on the same spikes?

10 more diodes in parallel with the existing FWBR could result in some changes (higher or lower spikes), then again it may not. It depends on the dynamics going on in the diodes during switching. Your best bet is to just try it.
