F_Brown,

Is it possible to simulate the attached circuit in your FEMM?

GL.

Since I am just learning FEMM at the moment, I lack the ability to integrate circuit analysis with magnetic analysis in FEMM or if that's even possible.  I could make a pure SPICE model of your device.  You know when using cut cores like that, the coils are usually put on the straight sections of the cores for two reasons:  One it's more difficult to put windings on the curved portion of the cores, and two having windings over the cut sections of the cores helps to reduce magnetic fringing there.

F_Brown,


Nice job on the simulation,
Of course you had to scale the current and turns too.
can you say what your primary and secondary numbers are at 400hz?


Thanks.

I am only using primary windings at the moment because I still have yet to figure out how to attach a load to the secondary in FEMM.  The secondary would just be open ended and generate a voltage without any current flow. 

The primary I am using for this is 1550 turns of 20awg wire, which is 1/2 the turns of the original 3100.  I set the current at 0.9 amps and raised the frequency of operation to 1kHz to prevent saturating the core.  That is maintaining the flux density under 1.5 Tesla's for the M19 silicon steel laminations.  This type of core is usually only driven to 1.0 T to 1.5 T because the material saturates at around 2 T.  If the core saturates, it would allow large current surges to propagate though the windings and cause bad things to happen.  I set the gap between the stator and rotor at 0.025".

At the moment I am preparing an animation of the flux density during a full rotation of the armature.

F_Brown,

Thanks for taking time to consider a simulation of the circuit. I do not know if Spice has a built in model for
magnetic amplifiers. I have tested this method by using two toroid Ferrite cores. But, as you say, it is much
more easy to wind cores that are cut. Even if you have to wind the curved part. It is my theory that the QEG
is nothing more than a magnetic amplifier with a free running tuned LC tank circuit. So two cores with a mutual
winding will be a good test to see if there is any gain or not. The nice thing with two cores and a mutual winding
is that you can use that as a AC (or pulsed DC) on/off switch. When the center coil is open then there is no
transfer of energy to the right output coil. When you short the center coil then you have a output. And the best
part is that NO energy is used to short the center coil. So you can build a parametric inductance switch and you do
not have to spend a lot of energy such as in any motor driven rotor etc. It is my hope that people read a little
about magnetic amplifiers because I think there is a lot of useful information there.

Information about magnetic amplifiers can be found here: http://www.tuks.nl/pdf/Reference_Material/Magnetic_Amplifiers/

I am familiar with magnetic amplifiers.  I could build a non-linear SPICE model that includes core saturation.  They run quite slowly though.

If James is operating the QEG as a mag-amp, then he's using the wrong core material, because silicon steel saturates quite slowly.  Mag-amps use a sharply saturating nickel-cobalt alloys to get cleaner off/on switching performance.

Luc,

In general terms, that posting by Peter Lindemann is basically correct in his reasoning and discussion of what's taking place from my perspective and from what I have learned over the past week.  However, where he stumbles and falls is in his claim of a COP of 1.2.  Notice he doesn't give any details about what that COP 1.2 even means.

Peter will never meet a challenge when somebody wants to get into an involved discussion with him about electronics and measurements and how a circuit actually words, etc, as far as I am aware.  People like Poynt99 and MarkE and PicoWatt could spin circles around Peter when it comes to electronics and measurements techniques and a whole gamut of hard core electronics and engineering stuff.  Peter is a lightweight that manages to create the illusion that he is very knowledgeable.

I am being somewhat harsh because I view Peter as a "pro" just like HopeGirl and company are crowd-funded pros that are deceiving people and acting unethically while creating the pretense of ethical behaviour.  Are they cons or are they clueless, I am not 100% sure.  But I myself have the common sense to get an expert opinion on something that I don't know much about.  I would be completely mortified to accept donations from people if I didn't know what I was doing.

So sorry to play the Bad Cop but Peter's COP 1.2 claims are junk.  If what he said was true his whole team would have received the Nobel Prize.

A magnetic core in an inductor or a transformer is a lossy mechanism for storing and then recovering magnetic energy by definition.  Even is it is 99.9% efficient at returning the energy that you put into it that is still lossy.  There is no such thing as a magnetic core returning more than you put into it.

Why is Peter claiming COP 1.2?  If you want to be really cynical you can speculate that he says that to keep the
"Peter Lindemann mystique/aura" going to keep those ticket sales high for the next Bedini/Lindemann/Aaron conference.  You play the tease to keep your audience stoked for the next paid live appearance.

Just keeping it real, I hope that you understand.

P.S.:  If any team does a faithful replication of this device the key to understanding it would be to construct a timing diagram that shows in front of your eyes how the thing works.  If there truly was over unity you would literally be able to show a "slice" in a waveform on your timing diagram where the free energy was manifesting itself.  The timing diagram and the associated schematic for any circuit and associated tests rules.  We will see if replication teams actually start reporting their results and if any of them show any timing diagrams.

How thoughtless of Lindermann's group to neglect to document their researcht.  The just forces any other interested party to have to repeat the same work just to get the answers they already found.

In spite that we now have Computational Electro-Magnetics software and laser cut laminations.  Maybe we can do better now than a COP of 1.2.
