I went through all 152 pages to see if I could find some scope shots.
These are all the images that I found.

Clanzers coils - really nice.

Clanzers build all done. What a tremendous job well done.

But the question remains.

We know with one pick up coil and a mag rotor with alternating polarities will produce a nice sine wave.

But now you have one polarity of magnets per side of the rotor and both polarities pass simultaneously across two pick-up coils, one per side that are in series. So for me, the sine wave should be two sinewaves, one going up from the zero mark while the other is going down from the zero mark and both meet again at the zero mark, and so on. Would that be considered double AC. A standard FWBR will take the two and make one because the two sides happen one after the other. But what happens in a FWBR when it is supplied simultaneous AC that is off  by 180 degrees. Something seems wrong here. Is it possible that Romeros' rotor magnets were not placed all the same side but alternating field and he got it wrong. I don't know but something tells me there is something really weird about it. If that is not the case, then....

It seems to me that there must be a way to arrange the pick-up coil directions that are facing the magnets so you will only and always get a positive wave or a negative wave, hence no FWBR would be required, just a diode per pair.

I will repeat this other point again about drive coils. The drive coil has to be pulsed on the side that is closest the core. There is no point pulsing the other side of the drive coil because the impress will have to travel across all the winds to hit the core. The energy will be strongest at the pulse point and degrade as it enters the core so you will wind up having the least impress on the core if the pulse is not on the closest side to the core. Please make sure this is so, and if it goes against the polarity of the magnets then you HAVE TO FLIP THE COIL OVER and not just switch the wires. This is of the greatest importance at this initial stage.

Once your drive coils are working and the wheel is turning, then is the time to take each pick-up coil pair and test them one by one for polarity given the clockwise motion of the mag wheel.

But all in all there is some damn nice work going on here and some great new toys to play around with. @Clanzers' build includes all the ifs-ands-or buts that one would have to anticipate so good work. Now all you need is to match this build skill with some great patience, not jumping to quick conclusions because obviously with so many variables, some being pretty weird indeed, patience will be required.

Quick update.

Right now my rig is waiting on new bearings.  I did notice some very strange effects while tweaking this motor.  I will post a video showing the effects once my new bearings arrive.

Based on something that I just noticed on my smaller test rig I would like to suggest folks try connecting the drive coils in parallel.  Based on what I saw it may have a very positive effect.  I can not wait to get my new bearings.

@ lasersaber

I've been following your build and thank you for sharing. I'm at the stage where I have my rotor stated just around 3.5V and it runs fairly smoothly with one generator pair and one collector coil pair.
Don't have a tacho and don't know what rev/minute though. However, I can only get like 4V (straight forward diode bridge without additional parallel diodes) after the bridge at about 9V DC in. I see reports like yourself getting 16V output from one coil pair? Can you please confirm whether your 16V output is from (one generator pair and one collector pair) or from (one generator pair and seven collector pairs)?

What am I doing wrong if I'm only picking up like 4V? Any idea or suggestions? Thanks.

cheers

Okay it is alive, so second video

Very cool!  3000rpm!  Can't wait till next weekend to see the power in, power out readings.

Congratulations!  Good run, beautiful construction!

Thanks for the tip lasersaber as that sounds important.  I'll look forward to your info when the new bearings arrive.  Is that one drive circuit running 2 coils in parallel or 2 drive circuits running 2 in parallel ?  Running from one or two hall sensors ?
