Upon searching Youtube, I only know of 1 experiment that was posted that examines a generator merging 2 output waves 90 degrees out of phase. If you know of any others, please post them.
Here is the only 1 I know of. He is using 4 magnet rotor and 8 coils creating 4 output circuits of 90 degree waves merged in series. And he is able to demonstrate a very noticeable speedup effect with lower input when shorting the last pair. And the three bulbs get considerably brighter.
This is the basic idea. But I think the effects can be drastically improved, by using a more UNIFORM magnetic field instead of separate magnets with large gaps. So my single magnet rotor should provide a continuous uniformity of the rotating magnetic field, thus capitalizing on the effect.

The diode and paired capacitors tell most of the story - though I wonder if he should have another capacitor pair capturing the opposite direction in parallel? Something else I can test with the shaft output of the Axial.

I'm listening- tell me your theory of the diode placement.
Only possibility I can think is perhaps the 90 degrees phases can only cancel Lenz with his configuration when both waves are on the same side of the polarity spectrum, so he is filtering out the undesirable parts.
So I printed out the coil bobbins and broke 1 while assembling. So now I am re-printing 1 more. I should have these coils wound and the basic model in operation today (I hope).

Ok so I got it together and the attraction to the cores started to fry the small motor. So before the motor went totally bankrupt, I removed the cores to gather my data..
The separate coils do not allow the waves to combine constructively. I have a good idea what I must do to fix this and try again. But now I must re-build the rotor on a stronger motor that won't give out so easily.
So the work continues!

While I am printing I needed to test with an old stator I made for something else that is close to what I need. And YEP, the waves are now constructive.
So I will now make a stator tight around the magnet with the optimal constructive configuration. This one not only has a HUGE unneeded gap, but is not exactly correct. The alignment still needs to be corrected. But even with this imperfect one, when I place the 2 waves in series, I get 1 near perfect merged sinewave.
This design makes using a core difficult but possible. So I will start with no core and go from there

I've watched this a few times now, and throught I'd check his other video's - he's covering up the cap junctions now - so maybe it's changed since Guests cannot see images in the messages. Please register at the forum by clicking here to see images. I wish I could understand Russian. By connecting the two coils (looks like both +) I think he is introducing the passive coil to the pulse (removes reluctance, speeds up rotor, changes resistance), which also creates EMF. And the diodes allow the back-emf to circulate in the opposite direction providing a small degree of reciprocation between the pairs of coils. I've seen similar effect by putting reverse biased shottky's between coils and tapping back to ground - motor speed up, lower power use, 12v load globes glow brighter. That's just my guess though.

I was going to suggest coreless with a magnet that strong.

Ok here is a pic of 2 coil setups. They both produce 2 phase 90 degrees apart, but one does it near perfect.
The first pic has separated individual coils that each span roughly 90 degrees of the rotational circumference. This does not take advantage of the full rotational field of the magnet and "Truncates" the waves. Because the waves are truncated, they can not smoothly merge to 1 output sinewave. Instead they produce the famous "M" shaped wave which haunts us all.
This is no good..
The 2nd coil arrangement produces a full and beautiful sinewave which takes advantage of the entire magnet's rotation. Now the 2 waves can merge to one near perfect pure sinewave.
Now I do not like the overlapping feature. I think this will act like a transformer and cross-talk between coils. I think this needs to be avoided. Which means I need to spin 2 separate magnets on 1 shaft, each inducing their own coil set keeping them magnetically isolated. Then combine the waves.
so that's where I am going!

You get the M shape because that's what the coil sees, a sharp angle, a flat spot where distance is greatest, then another crest for the opposite edge - try axial, with n / s / n / s.

The M shape is from a time variance. There is no M shape when using a single coil, only when the waves are merged. And the M goes away as my last video I showed when the coil utilizes the entire magnet's path, then the waves merge constructively.
I am only using 1 magnet, I need a completely uniform magnetic field with absolutely no gaps. I do not want many poles, only 2 with no gaps between.
This Polyphase has to be created as perfect as I can get it. Look at the scope's waves in the video below. Almost perfect... And when merged into 1 wave, it's perfectly sinusoidal.
Now the overlap needs to be eliminated.

Picking back up on this thread for now..
You can see my last post above this one- In the video, I managed to make a generator that produces 2 near perfect sinewaves 90 degrees out of phase.. But the small air coils obviously had terrible output, not enough to do experiments with..
So I think I need to make a better one to try some stuff with..
I will be using 4 of the strongest magnets I have, with a 2 stator layout.. One stator shifted from the other by 90 degrees. So the basic tests will be to use a rotating magnetic field (generator) to generate output that will also rotate..
The problem I am having with my solid state builds is the self-induction of the primary coils lowering the input.. But if these primary coils were replaced with rotating magnets, the scope of the project changes...
It will take me a few days to print all the parts and wind the coils and such.. But by this upcoming weekend I hope to have some more answers..
