@MileHigh: thank you for patiently explaining the basics, I am learning.

@tinman: I looked at your "LAG", very impressive. Could you please post a link to more information. At what stage is the project?

I did not try to build a new motor, I use an ordinary 12 V DC motor to spin a diametrically magnetised ring magnet. And I put a 10 µF cap in parallel with a generator coil placed in front of the spinning magnet.

The big 10 µF cap (in parallel with the generator coil) serves to simulate a generator coil with a massive self capacitance in order to bring the (faked) self resonance down to a low frequency (in this case 52 Hz). According to my opinion this allows to simulate the so called "reduced Lenz drag" or the "speed up under load" (what your LAG is doing).

Have a look at my video http://www.youtube.com/watch?v=vAXQBpuLu68 . I would be interested in your opinion, since you built a LAG.

Greetings, Conrad

Hi Conrad
Nice setup there,and a very simple wat to show the effect. I have always thought it works by releaving eddy current preasure within the generator coil-if there is such a thing?-just my way of trying to explain why it works. I think the motor is already loaded by the coils core,and when you draw power from that coil,it removes some of the drag from the core. A very simple test is to do what you did in the video,and record all measurement's, then remove the coil from the system,and see how much the motor draws at the same RPM as it was doing with the coil there. I think you will find that you dont gain as much as you loose with the coil in place.

The LAG works in a different way-i wonder who can guess how. I recon MH and TK will know how it work's. Anyway,i discontinued the project,as i knew what i wanted to achieve with it,and did just that. From that came the rotary transformer,and the results were much the same.

@Conradelektro,


I'm finding your resonant output coil tests extremely interesting. I want you to examine in retrospect the dramatic effect attaching resistors directly to the "Synchro Coil" produced compared to adding them as a load to the resonant capacitor electrodes. The LC tank supplies the speed up effect at lower RPM as you demonstrated. I used the loop back to source as a load, but resistors would speed the rotor up too. Why not return to the "Synchro Coil" test, now that you have the advantage of your new prime mover and the great experience gained from your resonant coil experiments? Gauge a resonant electrolytic capacitor to resonate with the old bifilar coil you wrapped at running rotor RPM. Don't forget the diode. Then measure the coil output with and without the magnet core through the resistor load, along with any DLE.  


These new tests would go much further then anything I've been able to accomplish so far. Don't shun this challenge simply because your radical departure from my original design caused me to have a conniption fit. There's a great deal of power that's available for the discovery.


What is Magnetic Resonance? How would one determine the magnetic matching frequency of the LC rotor resonance? This is where my speculations grew kind of far out, positing a "Terahertz fractal". However, magnetic resonance is an established science. I imagine one could test for it simply by running a series of pulse frequencies through the magnet core "Synchro Coil" and watching the scope traces. Then, the capacitor value and rotor frequency could be determined. This is the combination I believe I achieved just with intuitive skill alone.

@Conradelektro,


I found a video that demonstrates exactly the effect we're looking for. This video is a definitive video:

This video is a simple demonstration of Magnetic Resonance. The motion of the B1 field is analogous to the spinning rotor. The diametric  core field takes the place of the compass needle with it's two polarities. The frequency of the B1 field is adjusted to the natural vibration frequency of the compass needle. Repeated weak pushes have a large effect when applied in synchrony with the natural oscillation. This is the resonant condition!


What is the natural frequency of the stack of core magnets? How do we determine this? If we can ascertain this frequency, and match the LC and rotor resonance to it, we can derive a formula to apply universally to all these types of output coils. Follow through with this set of experiments with me, and together we'll succeed in making a very positive contribution.


Remember how difficult it was to achieve magnetic resonance at first by physically positioning the diametric stack in proximity to the spinning rotor. Determining the precise frequency of the core stack resonance through testing should solve the positioning problem and deliver a reliable generating coil. I think simply test tuning by feeding an adjusted spectrum of pulsed DC frequencies into the "Synchro coil" with scope probes attached should produce some obvious resonant signal patterns at the correct hertz. That magnetic resonance frequency determines our rotor speed and capacitor value. You already got there with it just by physically testing. Now you're uniquely situated to really get some awesome results! Surly you can appreciate now the tremendous potential that's been driving me to pursue this project so persistently. Think of all the coal we can save!

Conradelektro's darning needle rotor was only spinning at around 20 hertz when he got the magnet flutter. Igor Moroz's reed switch diode loop back to source bearingless neo sphere, is powered off a 1.3 volt battery, and in the mild 20 hertz flutter range of Conradelektro's vertical needle rotor. Igor is recovering a substantial amount of his power pulse through a reverse biased LED because his low voltage is not jumping the reed switch as Magluvin pointed out. Any substantial output from a magnetic resonant coil would project a massive COP when coupled with a near self sustainer like Igor's; Especially if a very low CMF for DLE could be achieved with a resonant LC tank, for speed up under load. Weak pushes are all that are required:
