Hmmm. Well I guess things have changed.
I'm not aware of any change. When I look a post 599 I read "You can see in the video that TDC is dead in the linear side of my waveform and the flat in exactly in between magnets."
This is correct. Peter's wave form is a bit different at the peaks, but other than that it represents the typical wave form picked up from a generator coil, or a pair of generator coils in series adding. Also in jln's gif, the waveform on the left must not represent the tdc position of the mag n coil below it. And it is the left shot that represents the muller, no? So his explanation may be different as to how it happens.
Correct, JLN's test was performed with a single coil, not two coils sandwiching the rotor magnet as per the Muller/Romero dynamo. However, the result is identical as shown with Peter's and EM's, scope shots, and they used two coils. But I see tdc vs waveform in his gif that represents what I am in favor of, but you are representing as not.
I don't know what you mean, but let me try to explain what might be the confusion; We are looking at two distinct wave forms; 1) that of the typical response captured by both Peter and EM et al, and 2) that of the wave form produced by Romero's setup; they are distinctly different despite the similarity at first glance. Ps the scope shot that you lay out that tdc is at the beginning of the flats, how are you determining those points?
There are two distinct characteristics that are give-aways as to which part of the wave form pertains to which position on the rotor. I have already shown in the following diagram how things look when all goes as expected (i.e. a conventional output wave form) (which you seemed in agreement with): The range between points 5 and 6 with the gently-decreasing then increasing slopes is clearly the transition from the end of magnet one, to the beginning of magnet two. The rate of change of flux in this range is relatively low, and results in the "flatish" looking part of the trace. The range between points 2 and 4 clearly indicate where the coil crosses each edge of the rotor magnet, passing across TDC in the middle. This area is characterized by a quasi-linear slope from one polarity to the opposite polarity. Now, examine Romero's scope trace again and look for these two characteristics; you'll find that the first (between points 5 and 6) is there but it is distorted or interrupted by a sharp transition, and the second (between points 2 and 4) is completely altered by transposing or seemingly delaying the negative excursion beginning at TDC. Does it make sense to you now? .99
