Hello, 

according to the suggestion of Chris, to make a seperate thread for each device  i start to post about varios experiments performed together with a friend using his axial flux generator setup.

Hello, here i put a link from a video of my friend, trying to replicate with an axial Flux generator, this was presuming that the Lenz force free generation on the device of skycollection could be a faseshifting effect.

 there are many more tests, but as mi friend is living in an other country we do all communications by mailing, and i have to review this to post the relevant things only. Some  info about the device: two rotors with 12 N52 magnets each . the stator has 9 coils  in trifase star connection, reciently we put cores made of powderd iron enclosed in epoxy resin. in the latest test we moved the magnets to bucking position, equal poles facing each other, and to our surprise the outputpower increased notably, we did this test inspired by the Bucking coils. Further testing with measurementes will done soon and posted in a video by my friend

The reason the output power was increased was the field lines are compressed from the bucking fields which increases the intensity of the E field just like all bucking field arrangements. the higher the compression the higher the output.

a person could actually build an opposing Axial Flux generator using electromagnets to massively compress the field lines causing the output to go through the roof. if one was to wind a twin opposite wound coils connected in the middle it could very well output a substantial amount of power.

if you care to see the arrangement i have had for years bouncing around in my head i can show it to you only if you want to.

this arrangement i have will surpass the output of a standard Axial Flux generator by a substantial amount.

Hi Marathonman, thank's for the comment, of course i am interesed in the arrangement you mentioned.Regards to the bucking coils as generatorcoils  i think we can also test this arrangement, in the actual setup the coils are embedded in resin which makes changes difficult, but we will make a new stator with exchangeable coils to be more flexible with different configurations. Your suggestions are appreciated.

In this setup below it would be just like the bucking coils but they are not switched in any way just powered up using an AVR type system. the bloch wall or collision point is right in the middle with both primary electromagnets being equal. since the magnetic fields are highly compressed but stationary the E fields are also but at different currant direction unlike Figuera's from different switching.

by winding one side opposite of the other with a space in between them as the bloch wall is adding nothing, the E fields are in different direction so by winding them in different directions the currant will flow the same direction in both coil halves.

as the rotor rotates it will experience different intensities of Electric field exactly mimicking that of a standard generator but DC output. by using large electromagnets the field lines can be very highly compressed passed that of a standard generator with NO cogging effect (Lenz) what so ever. the coils can then be paralleled or series to get proper output.  of course the spacing between coils will need to be experimented on to find the right gap.

the pic is very minimal just to present the idea.

Tell me what you think about it.

This is very interesting, i think we could arrange a test, as in this generator we got a really good outputpower with the n52 neo magnets, so it should work with the bucking coils also.We will tri when the new stator is ready. What about the Lenz force with such a setup? have you any results from the tests with your figueras device regarding the CEMF?

People think the Figuera device is Lenz less in which it is not. the secondary has Hysteresis and eddies just like a standard geny does which is why Figuera separated the primary and secondary cores to reduce this exposed to the primaries.

the Lenz force is balanced between the the secondary output coils in this design so it is nullified. i foresee no attraction forces that can't be overcome from the ironless secondary core.

a small motor should be able turn the rotor. the amazing thing is someone could get literally 40, 50 even 100 lbs pressure between them and still rotate the rotor with ease.

try that with a standard Axial Flux generator. the compression attainable with the bucking electromagnets are almost limitless. with hundreds of lbs pressure between the primaries you could literally melt the wires in the secondary coils from currant flow.

this is a Marathonman original and NO OTHER person has this idea anywhere. you heard it on Hyiq.

regards,

I agree that no geny can be free of eddy currents or hysteresis, i refered to the CEMF to the primary field coils.

the drawing with the bucking coil seems very logical to me , i would certainly beleave that it works and we will make that test when possible. what i cant really understand  how the bucking magnets give the output without any changing in axial direction of the coils, the neutral pressurezone is passing always thrue the center . But my knowledge in magnetics is limited, i'm trying to learn.

The situation is just like the Axial Flux generator with magnets except in this case it is with electromagnets, nothing has changed. the fields interact with the coils just the same weather it is one field  like with a north and a south or two fields north, north side by side. the only thing that has changed is in this case is the south field is replaced with a north field and compressed.

what this does is cause two fields with currant in two different directions so that is why the coils are wound in different directions to get the currant in both fields flowing in the same direction.

I understand your concerns but if it works with magnets it will work with electromagnets. as for the Cemf in the primaries,  it will be the same as a standard geny. the magnetic fields are on all the time with no change in currant or field so Cemf is reduce to nothing. once the fields are established the currant draw is reduced to that of the IR2 losses only. (ohmic losses)

I hope this makes sense to ya.

Just like i have referred to in the Figuera thread about standard generator and the Figuera device once the electromagnets are up to running conditions the power draw from the primaries (exciters) are reduced to that of just the IR2 losses. the only time the Cemf is prevalent is when the field is increased from the load increase on the external load. even then it is momentary then settles to the IR2 losses again. even though that pressure is still in the system to maintain the field it isn't using it only replacing the losses which are the IR2 losses.

Happy testing.

Below is the Magnetic Field in relation to the Electric Field and the rotation of either the magnets or the coils. notice the rotation trough the electric fields are not side to side but along it's radial axis through the fields. since the Figuera device is taken from side to side what this tells me is it doesn't matter which way you  traverse the electric field it will still produce currant flow.
