Hi Lumen,

you're making me think and interestingly I stumbled upon this video today and was wondering if this would qualify as a Lenz work around design?

I chopped the original video to get to the final design.

Please let me know what you think

I think it can be done much easier. I'll post a drawing of my new test device after I measure the coil and draw it up. It's much less complicated.

Hi lumen please post when you can. I'm looking forward to seeing it. I think you right that the lenz is certainly present, but the rotor material in this design will not see as it flips to become part of it. Anyway just a gut feel,

Very interesting and simpler design lumen

Thank you for sharing.

Just a few questions, why does the coil have bump?
also, is the rotor open at the bottom?... U shape?

This arrangement should prevent Lenz in the coil from affecting the rotor if that is possible.
The key factors are:
1: No movement between coil and magnet.
2: The field propagates outward as the rotor approaches the core and propagates into the core as the rotor moves away.
The idea is that Lenz will work to contain the field within the core as the magnet tries to push it outward into the rotor.
With Lenz working against the magnet not against the rotor.
When the rotor is moving away, Lenz will push back against the collapsing field and prevent pulling back on the rotor.
The total pull back on the rotor to the core can only be the same as the pull into the core as the field would be the same magnitude minus some losses from other events.
 
This is only a concept until proven to work anything like described.

Lumen, I hope you have something with your design, however, I can offer from my own experiments many years ago where I placed coils on the permanent magnets themselves, and spun iron segments past them, the back emf was still there and showed up on the input to the rotor. I also experimented with permanent magnets wound with output coils on both the rotor and on the stator. I was very confident at the time that the back emf in the stator coils would be cancelled by the back emf in the rotor coils,  but it was not. Very efficient induction but no cigar. It was a novel induction method without any core hysteresis. Magnets will switch polarities without heating up when employing them for both the rotor and the stator. They can also be employed to efficiently achieve induction at very high frequencies. Just picture permanent magnets wound with induction coils as the stator, and permanent magnets wound with induction coils, employed as the rotor segments. No iron at all in the generator.

I do believe what they have been doing in Indonesia does work... I have my doubts if there is a better way than what Syair has shown

EDIT... As an after thought, perhaps stationary magnets with induction coils in the outer stator as well as magnets wound with induction coils on the inner core, with iron segments passing in between.....something to chew on for awhile....

Why don't you guys try to analyse how it works by making a timing diagram for the device.  You could also make drawings for the flux flow for each stage of the rotation.

I believe there is a flux flow at the end of this video I shared yesterday.

Are there any real builds on it?

Also the magnets<-->coils flux interaction always go over shortest straight paths and when doing design for the magnetic flux switching that has to be accounted...
And if there is bended flux path between coil and magnet that complicates design when avoiding to hit induced magnetic force 3D vector(the Lenz force which will cause drag when aligned) on same line by external force causing magnetic flux change.

I watched the full chunk of that clip and at the end I am not sure what is being shown but it does not look like flux flows to me.  For the stuff being stated in the clip itself, I get uncomfortable when I listen to what is being said.  I can't exactly follow what he is saying and I am not going to watch it 10 times to try to figure it out.  Nor am I going to watch the original series of clips.  I note that the YouTube clip is a few years old.

The issue is this:  I think it's fair to say that whatever he was saying, the idea was based on some kind of "workaround."  You know, "My generator with the rotor cylinder sliced at a certain angle prevents back-EMF, bla, bla, whatever.  It often sounds very noble and is serious sounding, but in the back of my mind the "engineer" in me is saying, "No matter what, flux has to cut a coil, or a coil has to cut some flux, and it takes mechanical energy to do that if you are going to drive a load."  It's just the way it is, it's always there, and everything we know right now says that's the way the world works.

It's like you can take any fancy generator design and rip it apart and distil it down to it's bare essence, and there is still a magnet moving past a coil.

MileHigh,
Yes all that double talk is just too much to be anything but impressive sounding.
