Magnetic OU principle, You should really take a look at this !

If you haven't already I suggest you replace the rod holding the washers (tipping experiment) with something nonferrous and repeat the experiment.
I suspect the spreading washers increased the 'attraction zone and flux for the rod', between the magnets. This should also require more weights to cause tipping. 'Attraction zone' is not a formal term AFAIK.

This may start another battle but the washers, now magnets, focus more magnetic flux separated than compressed. This increase in flux concentration should also create a stronger pull on the horizontal rod. If the rod is nonferrous there should be no increase in focused flux and the distance between the washers should not be as great.
Hope this is helpful

Like I said 'zero circuitry'. I have a coil around one section of the stator for pickup purposes only. With my scope on 100mv/Div it barely registers when turned quickly by hand. If it shows continued promise I'll likely start another thread as it is nothing like what you've presented. Sorry, I'm busy enough proving to myself I am not an idiot so I rarely 'replicate' another's work.

Design is nowhere near complete. I need to include positioning screws for adjustments of axial/radial postion and balance. So far it looks like I'll have to beg for CNC time at work.

I'm doing all design on AutoCad with good measurements so once I can present it as useful or a complete mistake the info will be good.

Thank goodness this idea is in no way related to my previous works so I'll have no problems posting info. It uses part of the concept you proposed but includes others I haven't seen public before. I hope to have a POC to post by next week but can make no promises, yet. Then you can all tell me it is something done before but I seriously doubt it.

BTW: FEMM is useless on this.

BEP,
Looking forward to posting of your progress.
Hope all goes well.

BEP,
The rod is non-magnetic stainless.

Hello Sirs,

I try to understand this principe but i'm not natural english speaker and it's hard to understand all you say.

1/ The setup
Do you think this kind of simple setup can be a good firt approch ?
Does the LC resonant frequency be calculated be near the idéal rotation speed (in turn per second) ?

2/ Output évaluation
If i drive this setup with frequency generator (GBF) and choice a good capacitor for my coil i can easly évaluate the input power
But how to simple mesure the output ?

Molux,
I believe the rotary approach is the best way. Look at this video and tell me what you think.
Also, the best way to test this theory for true overunity is to use a scope to show that the supply voltage/current is constant when the rotor is moving and doing useful work.
Below is a link for the youtube rotary basic layout for testing the concept. It will need proximity switch added. The final product will need resonance element in design.
Feel free to write me if you have any questions. lafontegroup@charter.net

Molux, my english is bad and I was born and raised here in the United States.


Sorry for my bad english

BEP,
The rod is nonmagnetic stainless.

Thanks for that info. So the metal is probably type 300. Likely 316 stainless steel? I used 316 stainless steel fasteners in one project and found the metal to have an effect on the shape of the field but only while moving within the field.

Still, I'm puzzled why there is so much difference in attraction to the magnets when compressed or released. If the rod was ferromagnetic it would explain it. Perhaps the washers are easier to saturate while compressed? Your test results would be unwanted when dealing with the laminated rotor I described above. I want no differences between compressed and expanded and have none but none of the early tests I did were as inventive as yours.
