@mags and all

The higher the inductance of a coil the lower the resonate frequency?

yes  ;]

I've been pondering Bolt's guidance and the discussions about phase shifting, and I think that is not fully correct. A few thoughts...which may or may not be correct themselves:

1. A coil's self inductance is the result of an applied current yielding a changing magnetic field, that produces an induced current that resists the applied current. In a magnetic field the behavior is different...it is a changing magnetic field that induces a current large enough to produce an offsetting magnetic field. It is a magnetic force response, not a current response, and the inductance of a coil with an induced current is not the same as with an applied current...the inductance of it is much lower.

2. A power factor of zero does not eliminate Lenz. Lenz is a function of the current in the coil, and even with a power factor of zero, the current in the coil is still real at the point it is induced, which is perfectly in phase with the changing magnetic field. IR losses in resonant systems are real losses, and Lenz will happily lug a resonant system all day long.

3. When you add a series capacitor, you are really not building an LC system...you are building an RC system. The resistance is increasing with frequency due to skin effect, and the capacitive reactance is decreasing with frequency. The coil's inductance largely doesn't factor in. There will be an optimum point where both resistance and reactance are minimized, where resistance is a function of the frequency behavior of the wire.

4. The rotor magnet induces a very wide band of frequencies in the generator coil. The faster it turns, the wider the bandwidth.

5. The series capacitance is not tuning an inductance, it is implementing a high pass filter...limiting the lower (excitation) frequency but passing the higher frequencies. Means no lugging, but with good wire and wide bandwidth could still pass a bunch of energy.



So, assuming that those statements are true, that points the implementation in a specific direction.
1. The goal is wide bandwidth...turn it as fast as the wire and magnets will tolerate.
2. Use as large a capacitor as possible without lugging.
3. Use wire with the largest surface area as possible. Litz makes great sense.
4. Use the fastest diodes possible.


So, how then might it work?

As the rotor turns faster, the generator coil produces a wider and wider bandwidth and a higher and higher open circuit voltage. The series cap will pass everything above a certain frequency, and as much as 1/2*C*V^2 joules (where V is the peak open circuit voltage of the generator coil), but the wire resistance is increasing at the same time is increases losses. The smaller the cap value, the narrower the spike of current it will pass, and the higher the frequency components it passes, but at the same time that is being negatively affected by the wire's skin effect. As the pulse gets taller and narrower, the delay between the induced current and the magnetic response shifts as a greater and greater percentage of the pulse width. The greater that phase shift, the more that Lenz changes from being a drag to becoming a thrust. With a sufficiently large shift, the rotor effectively unloads. It is possible that biasing magnets would increase the phase delay (allowing it to operate at a lower frequency) and also improve the gen coil's response to the rotor magnet.

Per that mode of operating, I would expect the optimum waveform to be narrow spikes and there would be a band where the circuit would operate best. Too slow and not enough high frequency energy. Too fast and the skin effect of the wire drives the losses up. I would also expect that Litz wire (or wire with a large surface area) and fast diodes would be critical. And I would expect that at the relatively low speeds RUK was turning at that the effect would be fairly minimal, and on the edge of not working well enough to loop.

Just some thoughts...

Not really true so how do you explain a 3 phase motor in RV can be tuned to take no more than 15 watts yet the current measured with a clamp meter can be seen as over 10 amps? Lenz has no effect on  RLC when tuned to only VARS. The only reason current begins to have an effect is when the phase angle is shifted due to the load detuning the system which leans the phase angle from VARS to WATTs.

3. When you add a series capacitor, you are really not building an LC system...you are building an RC system. The resistance is increasing with frequency due to skin effect, and the capacitive reactance is decreasing with frequency. The coil's inductance largely doesn't factor in. There will be an optimum point where both resistance and reactance are minimized, where resistance is a function of the frequency behavior of the wire.

There is no resistance in an RLC system resistance only applies to  a phase angle close at or at one When the system is tuned to be reactive an almost unlimited amount of power can be sent over a single hair thin wire for miles as in the case of Avramenko

4. The rotor magnet induces a very wide band of frequencies in the generator coil. The faster it turns, the wider the bandwidth.

Not true the reactive system is frequency specific therefore it has a very narrow bandwidth where the inductance and the capacitance must be tuned to match the frequency of the system where the bandwidth is a function of the Q. This is why only a certain range of rpms must be met in order for the system to show OU.

5. The series capacitance is not tuning an inductance, it is implementing a high pass filter...limiting the lower (excitation) frequency but passing the higher frequencies. Means no lugging, but with good wire and wide bandwidth could still pass a bunch of energy.

Nope the series capacitance when tuned to the inductance acts as a counter balance where the voltage is max in the cap and the current in max in the coil if the desired effect is to tune to a power factor of Zero to prevent Lenz. In high pass situation of series cap it changes the phase angle as frequency increases impeding more and more of the current flow as the phase changes from 1 to 0  eventually its not a high pass filter but a total current blocking and nothing gets through becoming totally reactive UNLESS the source contains higher order harmonics from the fundamental then you see a separation of frequencies. High pass can have its place in these designs where the core is deliberately  saturated to produce an abundance of high order harmonics. These may be pulled off using a series cap as high pass filter can sometimes yield a useful o/p if the inductance is non linear by forcing it highish into the BH knee.

The aim to RE is to include it within the RLC loop as a load while maintaining a power factor of zero see Turtur for more indepth understanding.

"The crucial point is, that the converter has to be driven in a state short below the "energetical saturation", so that the energy-gain from the zero-point energy is maximal. This state of operation can be found in theory quite well, because in theoretical calculations it is easily possible to control the behaviour of the system with very different values of the system parameters very efficiently and very exactly. Under this control it is possible to adjust the system parameters, such as the capacity, the inductivity, the number of windings, and so on… "

Changing the system to be reactive cancels all Lenz.  ZPE is drawn into the system  while the current is held at zero when the voltage is maximum creates space Tensor moment causes immense amount of Kinetic energy to form within electron field boundaries which pulls energy from the ambient. As Don Smith quite rightly said if you move electrons you are creating waste! You must interface with them using space tensor. Tuning is nothing more than RF application taken to electrical principles to create standing waves. They are sometimes known as scalar waves but this clouds the issue as people actually go looking for some special scalar waves as it they exist in there own right. This is a Bearden, Bedini  cockk and ball story.

So there are many ways to skin a cat alike creating this VARS conditions can be done using caps and Romero agrees in fact he said its probably much easier to do so no speculation there. OR, use bifilar coils cancels self induction to prevent current flowing but what is really happening? In ideal coil which has suppressed the moving of electrons ie current in effect its doing the very same thing! The coil is now operating 90 degrees phase shifted to create VARS. For some mS as the magnet sweeps towards the coil, inductance circuit can approach say 50 VARS creates Space Tensor which acts on the ambient no current flows from the source ...yet. Energy which is HEAT all energy is heat as electron vibrations even down to absolute ZERO there is movement. Some of this heat is given up from the surrounding cause the coils to go cold now there are joules in the coils which pumps out a responsive opposite magnetic pulse which is ATTRACTED to the upcoming magnet causing acceleration and provides REAL joules to the dump cap.

Guys,

Is it possible that Slider has inadvertently created a MAGNACOASTER of sorts ?

Thoughts ?

@Bolt

This is the last I'm going to say about it, but I strongly disagree, based on my own lab work with a scope and spectrum analyzer. The coil output is wide band. Observed fact. If it were narrow, it would be a sine wave, and even your sim showed a pointy waveform. Pointy equal high frequency.

A motor running at resonance is not the same thing as a generator, because a coil with an applied current does not behave the same way as a coil with an induced current. I honestly don't thing your RV comparisons apply.

IR losses in resonant systems are real. Period. In order to have a magnetic field, you have to have a current. If you have a current and a non-zero resistance, the loss is real. The reason that you don't see much of that in an RV is because you are using a much larger winding than would normally be used for the amount of power you are using, not because of some magical tendency for the IR losses to disappear. You put 10 amps through a 1 ohm wire and you will dissipate 10 watts regardless of whether it is in or out of phase.

High frequency behaviors related to single wire power transmission are a completely different phenomenon, that has nothing to do with big VARS at low frequency.

As long as everyone keeps approaching it the way they are, everyone will keep getting the results they are getting.

I do agree that a series capacitance is helpful, but I honestly don't think it is for the reasons you state. If this were simply a matter of big VARS, I'm thinking we'd be seeing a whole lot of looped systems.

I've said my piece, I won't argue further.
