Another little experiment
Take a look at the circuit and see points A and B
When shorting in point A Lenz appears and the rotor feels a lot of drag.
when shorting in point B Lenz does not appear and the rpm increasses

Are you shorting the coils at points A and B continuously or in pulses as Kone has been describing? Also, I just want to confirm that according to your drawing, your generator coils are wired in a bucking (canceling) configuration?

Thank you,
Jason O

@Bolt, I was under the understanding that "Displacement Current" was a myth? or a Mathematical Convenience? Do I have this wrong?

No its real.  I give you some wiki extracts rather me use my version and not factual enough

"in electromagnetism, displacement current is a quantity that is defined in terms of the rate of change of electric displacement field. Displacement current has the units of electric current density, and it has an associated magnetic field just as actual currents do. However it is not an electric current of moving charges, but a time-varying electric field.

AND

"An example illustrating the need for the displacement current arises in connection with capacitors with no medium between the plates (in free space). Consider the charging capacitor in the figure. The capacitor is in a circuit that transfers charge (on a wire external to the capacitor) from the left plate to the right plate, charging the capacitor and increasing the electric field between its plates. The same current enters the right plate (say I ) as leaves the left plate. Although current is flowing through the capacitor, no actual charge is transported through the vacuum between its plates. Nonetheless, a magnetic field exists between the plates as though a current were present there as well. The explanation is that a displacement current ID flows in the vacuum, and this current produces the magnetic field in the region between the plates according to Ampère's law"

bolt,

back at this post of yours:

what were you using to generate those wave forms?

bolt,

OK, thanks.

What was your circuit and what were you tuning?

Very Excellent synopsis on the real root of the effect we want to tap into! I must admit that I (again) fell victim to interpreting the tuning methods in a conventional way, which resulted in me getting the same results as others here who reported the motor slowing down when tuning to resonance as opposed to speeding up.

Now in my case, I'm working with an existing four-pole air-cored pulse motor (1.1 mH each, 0.62 Ohms resistance). The motor is capable of running at up to 500V with a max speed of 11,000 RPMs. I have been using it lately for doing some of the coil shorting and resonance tuning tests, though I quickly realized that I have been looking at this from the wrong perspective.

One thing I should ask is if the effect which you described requires the use of a metallic core (in the mechanical case)?

Also, is this effect best manifested with high inductance, high resistance windings as compared to low impedance windings? (the evidence here so far is obviously the high Z coils, but I thought i would ask.)

Lastly, the principles you were describing I would love to learn and intuitively understand a bit more. Would you happen to have any good sources that you would recommend for one to get more acquainted with the ideas you discussed (specifically, the idea about working with the electric field of the coil to tap the energy of the magnets, as opposed to conventional induction).

Thanks!
