Confirming the Delayed Lenz Effect

[DeepCut]

OK, quite a few things to absorb there.

Hoptoad you said "the rise time of the generating coils is not the cause of the AUL".

You then said "It is specifically the ratio between the total combined resistance of the load and the coil itself, and the inductive reactance of the coil, that matters most."

Well, the rise time of the generator coil IS the ratio between the total resistance and the inductance ?

Newton, you said "If AUL happens because of delayed lenz's effect,  then it should happen at all speeds of the rotor but we know that it happens only after crossing certain minimum speed. ".

If it happens because of a delayed rise time then it SHOULDN't happen at all speeds of the rotor, if it was about releasing CEMF when the magnet was at TDC then we would have dead zones and normal generator action zones.

Sorry to be off topic, but

And this is where you are wrong...
When it comes to induction the reaction is not instant. It is restricted by the speed of light!
That is why there is a possibility for that 'trick' (Delayed Lenz) to happen.
Tesla knew that and that is why his transformer is so interesting.
Imagine pulsing a one turn primary (d=2m) with a nano second HV pulse and turning of the power...
The secondary in the middle will receive that disturbance of the field (which 'travels' through the air at the speed of light @~0,3 m/ns) ~3ns later!
So any EMF induced in the secondary is decoupled from the primary power, and that 'reflected BackEMF WAVE' can be harvested back in the primary.

Is it not?

So in theory a radio emitter/receiver which is basically a loosely coupled air core transformer can be OU at condition the receiver is at 1/4 wave from the emitter.
Natural over-unity !? This concept could be applied to any frequencies and radio wave man made or natural !?
So first, a coil emit a wave then the receiver absorb that wave and produce a "back wave" 180° opposed (as per Lenz Law explain). Before that "back wave" cut the emitter coil, the power is stopped or polarity reversed (to recharge source with that back wave). Then you have OU...


I speak about that because I 've put in the download section some scientific Chinese paper that explain the possibility of such weird things.

Thanks Schubert, i will read the papers.

Schubert
  A primer wave goes out but is reflected eventually. On it's return back it stacks up against more outbound waves and gains some power relative to the outbound wave. A transmission of information can be piggybacked onto this wave to increase distance of transmission with out adding extra power. Normal use is to filter out everything but the information. If a freaquency matching a wavelength of a steady nture not man made can be sent out the extra power can be drained off as a surplus. Cell phones use very unique patch antannas,very small. When you operate on made made frequencies they claim theft even though they except no resposibillty for trespass. You go round and round, hairpin ect..I even went as far as looking into pizzo transducers weapons grade to see if it could be used as a collector if tickled with RF. Mostly I see a lot of red tape. Good luck

snip...

The rise time (of a loaded coil) is affected by the combined impedance of the inductive reactance and the circuit resistance.

Lets look at the two following scenarios (examples only, for the purpose of depicting the ratio difference).

CCt 1.  A) Coil and cct resistance = 5 ohm            B) Coil impedance (inductive reactance) at a given rpm =  2ohm
Total Impedance = square root of ((5*5)+(2*2)) = square root (29) = 5.385 ohms
Reactance less than resistance:        Result = DUL

CCt 2.  A) Coil and cct resistance = 2 ohm            B) Coil impedance (inductive reactance) at a given rpm =  5ohm
Total Impedance = square root of ((2*2)+(5*5)) = square root (29) = 5.385 ohms
Reactance greater than resistance:         Result = AUL

Same total impedance, with same effective rise time, but different ratio between inductive reactance & total circuit resistance.
The voltage rise time and the current phase shift are two different phenomena, though both are affected by impedance.
Rise time is affected by total impedance, while phase shift is affected by the ratio of resistance and reactance which forms the total impedance.
