In my next project will try to replicate the "The new generator no effect counter B. EMF part 2".
The project will consist:
Inside:- Stator with 18 coils.
Middle:- Rotor made of steel with slots ( I still working ). The lathe part was done but I need to machine the slots.
Outside :- The magnets array, with ceramic or neodymium.


Check the pictures..

Hi Arivaldo,

Would you mind editing your picture to have less pixel number? Now it has 1710x924 and the optimum horizontal size which does not extend the forum thread width to the right hand side as much as that is about 900x (now you have 1710x).
You can easily reduce your picture size by using Window built-in Paint or any other picture editor which can show size in pixels.
In this picture you have left too much empty white space around the actual photos, so it is easy to remove it in Paint for instance by rectangularly select the photos in the middle and copy and paste it into a new picture. I can do it for you if you wish.

Guys,

JLN and TinseKoala have already shown motors that don't manifest generator action (BEMF) - the ORBO and Orbette.

If you think so try to replicate than, but we have more than you have. Have a look from the beginning to this topic.

Hi everyone,

a quick test of the thngr's simple build of Ramadan Device

Link to video: https://www.youtube.com/watch?v=0wP1GSLa_AY

Next I'm working on using the motors bushes and commutator to power the electromagnet coils.

Luc:
I do not think they are some kind of sine wave as I suspected produces a square waves which couses broad spectrum of radio waves.(or it may be new discovery; perhaps gravity waves..) two years before I did calculate a gravity engine which uses 10N/watt reactionless drive uses only machanical parts and energy unlike rokets, but energy puring in wether it moves or not.(energy can be destroyed :D ) If we able to produce energy the oppsite effect may occur.(or it is only godzilla size Barkhausen effect couses mause to malfunction)

your electromagnet seems to very low voltage but much ampere. electromagnets need DC. and so many turns that fits the slot.

Guys,

JLN and TinseKoala have already shown motors that don't manifest generator action (BEMF) - the ORBO and Orbette.
To be strictly correct... only the Orbette 2.0 has actually shown this effect. It is a Core Effect motor, it does not operate by electromagnetic attraction/repulsion. Orbette 1.0 used different configurations of toroids and I never tuned it in this way. I did not find Jean-Louis's demonstration convincing, although he may have succeeded as well.

Applied current to the carefully toroidally-wound coils causes a change in the magnetic permeability of the special core material ("square" loop hysteresis in the B-H curve), saturating it magnetically.  This change in permeability reduces the attraction of the core to permanent magnets, equally without regard to magnet _or current_ polarity. This allows the non-intuitive Core Effect which drives the motor: the magnets in the rotor are attracted to the toroidal cores when the coil current is _off_ and are less attracted when the current is _on_. Again, equally without regard to either magnet or current polarity. So the Core Effect drives the rotor by allowing full strength, non-powered, attraction as the rotor magnets approach the toroid, and _reducing_ the pull back attraction as the magnets pass "bottom dead center" and begin moving away from the toroid.

This Core Effect allows one carefully to position the toroidal coil-core assembly near a double row rotor so that the fields from the magnets "null" at the position of the core assembly, hence virtually eliminating any generator effect that is normally caused by moving magnets past a coil. The unique thing about the Core Effect is that this does not affect the actual magnetic attraction to the ferrite toroid core! So it is possible to tune the motor so that no normal generator effect occurs, but the rotor is still driven strongly by the Core Effect change in permeability.

Steorn even claimed that the rotor magnets in the approach to the cores actually helped drive the cores to saturation, enabling very small currents to "finish the job" and produce the full Core Effect. I wasn't able to confirm this with my equipment and materials, but it seems likely that it is true. What isn't true is Steorn's claim that this process produced overunity performance.

However, this is a very different thing from "delayed or no Lenz effect" or the production of CEMF by current supplied to the coils. These effects happen whenever coils are supplied with (pulsed) current. The Orbette toroids still produce an inductive backspike when rapidly switched off -- which happens at a time when the magnets are maximally distant from the core!

Yes, it operates by more attraction/less attraction of a hard magnet to soft ferrite.  It is a 3D effect.
This is different (and more interesting IMO) than other pulse motors in this thread that exhibit a high yawn factor.

Applied current to the carefully toroidally-wound coils causes a change in the magnetic permeability of the special core material ("square" loop hysteresis in the B-H curve), saturating it magnetically. 
I don't think that saturation of the magnetic domain polarization in one direction is necessary to limit the polarization freedom in an orthogonal direction (a 3D effect).  When domains are polarized in one direction then they cannot easily polarize in a perpendicular direction at the same time and that lack of freedom decreases their response to external field in that perpendicular direction (this response manifests itself as permeability).

This change in permeability reduces the attraction of the core to permanent magnets, equally without regard to magnet _or current_ polarity. This allows the non-intuitive Core Effect which drives the motor: the magnets in the rotor are attracted to the toroidal cores when the coil current is _off_ and are less attracted when the current is _on_. Again, equally without regard to either magnet or current polarity. So the Core Effect drives the rotor by allowing full strength, non-powered, attraction as the rotor magnets approach the toroid, and _reducing_ the pull back attraction as the magnets pass "bottom dead center" and begin moving away from the toroid.
Yup.  I would add that this change in permeability is anisotropic and ideally its maximal decrease occurs in the direction parallel to the magnetic flux coming from the permanent magnets.

This Core Effect allows one carefully to position the toroidal coil-core assembly near a double row rotor so that the fields from the magnets "null" at the position of the core assembly, hence virtually eliminating any generator effect that is normally caused by moving magnets past a coil. The unique thing about the Core Effect is that this does not affect the actual magnetic attraction to the ferrite toroid core! So it is possible to tune the motor so that no normal generator effect occurs, but the rotor is still driven strongly by the Core Effect change in permeability.
Even more so if the core is wound with even number of back-and-forth layers so the circumferential current is cancelled and the only current remaining is all parallel to the flux coming from the parallel magnets ...which would make the H vector (MMF) very perpendicular to the flux coming from the magnets.

Steorn even claimed that the rotor magnets in the approach to the cores actually helped drive the cores to saturation, enabling very small currents to "finish the job" and produce the full Core Effect.
That makes sense because of vector addition.
Any flux perpendicular to the MMF vector (vector tangent to the circumference of the toroid) will turn the resultant vector sum away from this tangent but that vector will be longer (have larger absolute value, which is limited by the maximum B saturation level)

What isn't true is Steorn's claim that this process produced overunity performance.
Yes, they seem to made a scoposcopy error in their claim of that.

However, this is a very different thing from "delayed or no Lenz effect" or the production of CEMF by current supplied to the coils. These effects happen whenever coils are supplied with (pulsed) current.
The Orbette toroids still produce an inductive backspike when rapidly switched off -- which happens at a time when the magnets are maximally distant from the core!
Because the Orbette toroids still store magnetic field energy and this  energy has to dissipate somehow when the toroid winding becomes open.  You could recover this energy into a capacitor and recycle it for the next cycle.

Theoretically the energy stored in the coil is proportional to the polarization of the ferrite along the coil's magnetization axis (parallel to the circumference for a toroidal core) plus its MMF.

Maybe you should go and post in the Orbo thread then
