@Omega, @Omnibus, @tesla

thanks for sharing the excel sheets.

Indeed the one with real data is from BEMF-Test and doesn't match to the other graphs.
I had a look to the original scope shot from the video an made a V*I graph that would fit to the blue line on the scope. (pic1)
So this negative spike comes right after the magnets have passed the drive coils, but before they reach the collector coil.
I thought about it but I can't see a possibility that would fit.

But: IF the toroid isn't working as it was said by Sean then it would match perfectly.
Sean says the ferromagnetic material in the toroid attracts the magnet then the coil hides the ferro and the magnet passes by.
After looking at the data my conclusion is: They attract with the coil and then they push with the other polarity. So perhaps the toroid isn't wound just by one wire but by two in other direction. So the north/south magnets -array makes even more sense.

Just a guess but it wouldn't surprise me if Sean hides some basic principles here.

just forgot: pic2 is the integral result of pic1. It matches the blue trace on the steorn-scope quite well.

So the question whether the negative energy spikes are due to current being fed back to the source is answered. It is not...

IMO the small spikes seen in the input is due to resonance between the toroid inductance and it's parallel capacitance. It looks like a spike because the line is so thin, so you can't seen the oscillations.

Also, there is no resistance connected at the output, the coil is simply shorted via a connector. So whoever said that in the other forum is not telling a fact.

Who told you that. Of course there's a resistor.

Ok motor been running at 300rpm on 1.25volts overnight (9 hours)

Ok my Ossie motor which is informing my new Orbo replication (see what I did there ) has been running on a 1.5V Everready Energizer Alkaline D Cell for over 19 hours at 300RPM.

The total friction consumed by my terribly unbalanced replication at 1600 rpm is 4.36mW. Without even capturing any energy it would run for 124 days on a single 10Ah 1.3V D-cell battery.

@Omega_0 and the rest,

I don't think the original data I sent you differs from the Saturday demo data. What is being done in the Saturday's demo to produce the bottom (input) trace is to extract only the, what they correctly call, net input energy. That is, the bottom trace only shows the energy with all losses subtracted. That's how I understand it. Therefore, probably, it is not the integral(V*I)dt which should be plotted in that Excel sheet but integral(V*I - I^2R)dt where R = 4.8Ohms. See what will happen if you do it that way. It is crucial to understand well what the shape of the input trace is due to.
