I hope people feel it is relevant, on this this thread.
I finished winding my motor and it worked, not the best but it is a start.
So, I built a brushless motor with no permanent magnets, just an itch I had to scratch. The build is very similar to the 90* gen, posted by UFO, the rotor is also similar to Dragons rotor.
The first of the video is the build, last min or two is the motor spinning.

http://youtu.be/o6yZQpX9y5k

Again, just an experiment, will probably switch to pm rotor.

Grumage and jimboot, great testing. Grumage my gen rotor is similar to your, I hope to test mine soon.
Excellent work. Wish I had half your skill. Beautiful build. Nice bobbins too! Thanks for the vid, really helpful

Hey there jimboot

Glad you found it usefull. I should have made extra bobbins, with different shaped ends, all at once in the beginning of the build. I am going to take it apart and modify the bobbins a little narrower. I ordered some magnets for the next rotor, as well.
Later

Hi all,

I attempted to build an outrunner version of this type of generator. Since I have several variants of outrunners to choose from I thought that it would be easiest for me to modify and thus complete a test unit. Well, I have no funds or time available to work on this now.

So, I have taken it ias far as I can without finnishing this build. The reason for even posting this is that it may in fact be easier to work with for some who are sitting on the sidelines mildly interested, but not fully comitted to building from scratch or some other reasons.

With that all said, here is the build:

I had an old ceiling fan with an attached light kit that I decided to use as the base for this low lenz generator.



After taking the fan apart, i planned on attaching a steel pipe section inside the brown outer casing to hold some neo magnets, and to complete the magnetic circuit on the backs of the magnets.

Here you can see me holding one magnet sort of in the position I would have liked it to be in:



Anyway, I am completely unavailable for working further on this unit. If anyone wants to take this thought farther - GO FOR IT!

Also, I have a build thread over at http://open-source-energy.org/?topic=2326.0 that details most of what I had in mind.

Hi all,
Just an update. I've switched to a smart drive washing machine stator which a lot of guys are making wind gens from. It looks like about 22awg. Got the idea from Gerard Morins latest vid. Only thing is that the mags have to be on the outside diameter not the inside. Trying to work out how to remove the ceramic mags from the rotor without damaging them now.

Hi everyone,

I've been busy with another project for the past 3 weeks and didn't have the time to complete one of my last experiment to confirm if this effect has any value.
So before closing the book on this one, since my previous version was not showing a good results and was also a different design, I wanted to build a single coil version of Dragon's version since he claimed to have some good results.

Even with these changes, my results are not positive, however, I made a video of it anyways so all can see.

From all the replication attempts that I've seen, researchers are not doing power calculations (watts in and watts out), so as far as I'm concerned they won't see the reality until they do.

Link to video: https://www.youtube.com/watch?v=O0souZVPKw8

I'm moving on to testing Erfinder's multi strand bucking coils.

Luc

Hi Dragon,
How are you doing with this project I am very interested in building the same thing. Can I help you with yours?
Thanks, Scot

This was as far as I got when I decided to shelf the idea while it was so unbearable to work in a frozen shop. As soon as I clear the clutter I'll pull it out again and complete it.

This is a remake of the small original tests and is ultra low cogging. I ended up remaking the entire rotor assembly and installed iron wire instead of silicon or solids... made a whole different machine.

I have a ton of projects in the works but as soon as I get the motor built I'll start posting more about it...

What are you working on in this area?

Hi Dragon,
I just finished a hydrogen injector for Russ at RWG research.
I am a complete idiot when it comes to motors and electrical devices but I can see that there are some very good ideas to make generators more efficient.
I would like to help in the mechanical and machining area which doesn't help you much but I thought maybe I could get you some silicon steel.
Do you have projects that I could help machine parts for I'm kinda looking to trade help for help as I don't just want to just take without giving.
Thanks, Scot

Interestingly enough I was thinking of you a few days ago, wondering where you're at with the build.

Thanks for the update and really looking forward to some test results.

Thanks for sharing

10kw 220v 50hz 1500rpm gen is convert to the new gen ,but the gen voltage is about 25v NO LOAD at 700rpm,the pm magnet is 100mm *50mm*10mm N52,arrangement NSNS,i dont know why the voltage is so low。
here is some pic。

Generating Fields...

Hello Aweiaini,

IMO I do not find 'suitable' your Generating Coils Fields arrangement versus your Four Pole Iron Segments, therefore, the magnets which are not seen on pics...

The Stator Generating Field overlapped coils are based on only two poles, while it has Four eight pole single coils, which seems for the exciting circuit.

Are you reproducing the Original Rotary Stator segments size circumference exactly as it was?

I see too wide gap between each iron segment.

[IMG][/IMG]

In my opinion you will need the iron transfer cores to be matching the smaller size overlapped coils, meaning from two to four poles size from stator generator core, and not based on the four larger coils, which are not overlapped. That limits your continuous and increasing V generation.

Also, you do not need the "T" shaped laminated iron ...that is wasted space from solid magnetic field transfer, use semi arc rectangular segments. There is no wires going there...so, no need for that T shape. And make them not that deep, that is also 'delayed' transfer on the long run.


Just my two cents


Good luck there!


Ufopolitics.

Sorry, but I do not think that would generate properly...

You have to keep the sweeping ratio Geometry, you have a 36 poles stator, that gives you @ -/+ 10 per pole (more likely around 8.5), meaning each Magnet, and Iron Core MUST BE within at least, Eighty Degrees (80) and having a gap between them of around 10.

This Angles must be measured from shaft center to outer area.

Take a look at CAD below, then look at your design:

[IMG][/IMG]


Hope this helps you...

Plus, you must realize you are using straight magnets (not Arc Segments), therefore you already have a loss in gap geometry transfer communication.

Aweiaini,

According to your CAD you have around 60 of iron core sweep, including the salient "T" design which also have loss. Meaning your Gap between each iron core segment is 30.

I would try, if not available Arc Segment Neo's...to use two rectangular magnets (instead of just one) per each Iron Core Element Sweep Angle, like I show on right side of your CAD:

[IMG][/IMG]

I am sure that design would increase EMF Generation considerably.


Regards

i think if the magnet pole is too large,the iron core will shorted the mag circuit
,so my design the mag pole is smaller。

Short circuiting the "Magnetic Circuit"?...

No such a thing...can't "short" magnetism, it will always 'search' for stable points....you either get one pole or the other...or nothing.

First you MUST use SOLID IRON PIECES...and forget about Laminated sheets of steel...

So, NO LAMINATED IRON SHEETS.

Take a look below:

[IMG][/IMG]

See what happens in REALITY when looking through cheap Magnetic Viewing Film??

[IMG][/IMG]

Above is magnetization of Iron Bar

Iron Bar could be moved along both magnets...and the division line will not move (Call it Domain Wall, Dielectric Plane...Bloch Wall, etc whatever...fact is, a division between poles) ...so that line dividing iron mass will just 'fluctuate' according to the mass inner 'imperfections' ...

Guys, in order to understand about all this projects, we will need to kind off forget about many, many things we were taught in school...like "Eddy" or Jamie Currents...Magnetic "Circuits", etc,etc...and Open Our Minds a bit...


However, the only thing I see about this design...is that Iron Elements will not 'swap' polarity like it will if magnets will rotate along the generating fields path, they will just transfer within the field area ...unless magnets are offset related to field coils...and still, no swapping of iron...

NO LAMINATED IRON SHEETS?I have try it some days ago,and the SOLID IRON PIECES become very hot,the drag is large。
Short circuiting means the "Magnetic flux Circuit",the gen coils cant be magnetized 。so generate electricity efficiency is low。

Heat caused by neos

Rotating iron next to neos is a good recipe for a heater.
See:Fuelless Friction Heater And Other Heaters
Try some ceramic magnets so as not to saturate the core as bad.

In aweiaini's version of this device, he uses laminations.
Magnets are satationary in the inside of the laminated steel iron poles. Thus, these laminated steel poles are the rotating members rotating past not only the output coils, but also past the magnets, thus completeing and interrupting the flux from the magnets to the coils (producing ac power). So Aweiaini's poles are not as long, which leaves the coils in a state of limbo for awhile.

As the longer iron pole pieces move past the next magnet (opposite polarity) then they take on that opposite polarity and converslely flip the output coils that were on the original polarity. This gives the output much higher hertz per RPM (double?) and the faster jump of polarity in the coils, gives a higher voltage per RPM. Does being made of laminations cause the flux not to flip evenly? Would this cause a staggered progression of pole change instead of one quick reversal?

In the original version by syairchairun, the iron pieces are sections of an iron pipe cut and shaped to match the magnet poles. If I recall the original video correctly, they were also quite thin comparatavely.

Oh well, just trying to understand the differences and what the special ingredients are.

I have a 10 HP 3 phase motor with the rotor made into a P.M. generator. I put 1x .5. x 2 Neos on the rotor which generates at low rpm but higher rpm just causes heat. I think if I tear all of that off and cut the shaft, making a cage to hold the iron pieces etc.... I could replicate as close to the original as I can get without buying the exact generator. The only things I would need is some machining of the rotor and bearing / iron rotor covers.

At least this is my take on the device.
I sure would like to resume my testing of this concept, perhaps in a month or two I can find some more experimenting budget.

yes,This gives the output much higher hertz per RPM,if the tow pole close by each other like the upside picture show .you can see the hz form upside picture.
the first one i replicated is a three phase generator 7.5kw 3000rpm two pole(NS),i find the problem is that output voltage is low ,about 40v ,so i modify the 10kw gen 4 pole 1500rpm,i wish it could improve the voltage,but it could not。i think the problem may be that generator coil cant be exploited completely ,the reason is this style gen 。if this time could not success,i will modify a ebike motor,hereby improve the output voltage。

Capacitors?

Did you try capacitors between the phases?

In the original version by syairchairun, he shows several capacitors attached to the output lines.

I have just re-read this thread from the start and noticed something worrying. I'm sure most would agree that user 'dragon' appeared to be making real progress on this generator. So it is sad to see that right after he posted his video where his 3" rotor/8-guage-coils setup was producing 20+ amps (@0.5v), the very next day, a spate of first-time posters to this thread show up posting 'results' that seemed barely relevant to this thread. At least one poster noticed this and asked for the thread to be kept on-topic. Directly after this, 'dragon' removed ALL of his pics from ALL of his posts, and the interlopers disappeared, never to post again! Maybe I'm reading too much into this, maybe not, definitely suspicious though in the retrospective-re-read sort of way...

While it's fresh in my mind, 'dragon' also said that a solid-iron rotor is NOT the only way to go, he used iron-wire, with very favourable results apparently. I always wondered about the heat a solid rotor would generate and its effect on the neos.

It is Fake

Hi all.
I believe it fake. Here is the prove:
Generator like this has a magnetic in its rotor, it will not produce such much energy with his claim in that RPM.
also where is the original rotor of his generator, i did not
See it in his vedio. The rotor has a magnet in it otherwise wont generate that energy. It is an induction motor with magnets in its rotor.
Another prove is this youtube [URL="https://www.youtube.com/watch?v=N-6lUxXgTYA"]
This guy said it has a magnet in its rotor it behave like this claim.

Thanks

Flynn parallel path design

Hi Friends
I know that Luc Gotoluc has interest about this theme .I have watched many videos of him These were very useful For that reason I share also a video from me perhaps some other memeber like it too https://www.youtube.com/watch?v=3uGsQMGu4f4&t=241s

Hi selnet

That is an interesting motor design.
Are you the builder in this video?

Thanks for sharing
