Got some news on my alternator setup


got frequencies like 1250hz fundamental  and  overtones from positive of the bridge rectifier to the middle of the star connection


got 2450hz and harmonics from full bridge rectifier configuration...  up to 45v


i just have a problem my motor is weak and under load will reduce too much its speed.. i have only a 1/3 hp motor :(


however


got an interesting idea


What if!!! we oscillate the water with an inductor causing ac resonance, but we provide a dc off set synchronized with the resonance? 
 
in my opinion the alternating current on the water will not have the 1,24volts limitation and so the dc off set will allow that half of the current of the ac voltage to be dc somehow... check this:

i added some stray capacitances and resistances
adjusting the inductor in series with the coupled chokes (witch generate the dc offset) you minimize the ac voltage or the negative peak...


jst an idea...


result 4 amps 12v


960v across the capacitor having 81v negative peak... would this make electrolysis???


oh and notice that i'm inputing about 50w peak and i'm getting 90w peak across the resistance...


the boton diode is not really needed but help a bit


this second circuit uses a capacitor instead of the inductor in series and get
6,5amps 12v peak 75w consume


but the resistor see a peak of 1,2kv positive and 100v negative with peak 140watts

With standard electrical  components (capacitors, resistors, diodes transformers and logics) it is only possible to get 8.5 volts in the water fuel cell without causing amps.. sure you can get 45 but there are amps..
Sure you could put a capacitor in series to restrict amps but then you are isolating electrically.. Sure you could connect a resistor in parallel with the capacitor but does it give the same effects as figure 7 under a load? no.

First comes understanding Stans plate resistor (uniquely made electrical component), then comes the rest of the  conventional parts.


Column 8 Row 65
       
  "In generation of the hydrogen and oxygen gasses to an infinite limit,  as not yet fully appreciated, the upper level of voltage level is  removed WITH the UTILIZATION of the ELECTRON INHIBITOR of FIGURE 7"

The voltage level is 8.5 volts MAX with conventional parts without leakage of amps. So if you want to get higher then 8.5 volts it would be wise to take stans statement as true.. 

Its like the answer is in front of you but your still on a path ignoring this fact as if it weren't true.. 


A circuit simulator wont show you the answers.. It doesn't have the option of adding Stan's unique component into the simulator..

yes i agree with you that simulation is not going to simulate perfectly his strange components and its interactions... however on the simulation the capacitor with the resistor in parallel was the wfc ... i tried to substitute this by a small value 100ohm resistor and worked even better too... what i tried to show with this simulation is that i created a dc off set using the charging chokes mutually coupled and got higher voltage on the "water capacitor" load than the transformer was putting out...  the transformer should only give 360v and i was getting up to 1200 volts with the 10kohm water resistance... using only 70 watts.. well i think this is a good figure.. 


i have figured out another thing


while analyzing the harmonic frequencies coming out from my alternator i get this


Fundamental = 1,140 Hz
2° Harmonic FX2 = 2,280 Hz
3° Harmonic FX3 = 3,420
4° Harmonic FX4 = 4,560
5° Harmonic FX5 = 5,700


Do you remember his equipment electrical polarization process...  X, X2, X3, X4

well got some nice frequencies coming out alternator... 55volts applying 12v to the field coil... however under load the speed change so as frequency... actually the motor don't stand not even to charge the battery(got a new battery today), not even using the voltage regulator... capacitor fries cause rpm drops with load and it drop a lot... got to get a 2hp motor...(my is 1/3 Hp)


however harmonic frequencies are multiples of the fundamental, like i described.. many harmonics...


strangely 3phase full wave rectified with the six diodes not on the neutral.. i get less harmonics and fundamental is 2,280khz (double)


now i think is about driving the vic and adjust the chokes to match the right frequency... Need to understand also the wavelength thing better too... I think that i'm going to the university today and find someone that can help... =)


i will try think of this device as it was a filter. taking the high frequencies from one side §(water) and low frequencies to the inductors side... band pass maybe.. while still having a dc offset


got to find a motor today too!


but i'm going to try this things about the harmonics here,...


I was reading something really interesting about dangerous torsional resonances on crankshafts of generators witch cracks the crankshafts. The document is in my language and is from serious university of electrical engineering...


it also explains very well alternator connections and phase power ... there is one type called zigzag hehe


from now i will use neutral for the center of the star...


i would like to rewound the alternator with smaller gauge wire to get higher voltage... hell of work...


the frequency of each individual secondary of the alternator is 380 hz so i think that i have +- 3,800 Rpm...


i believe that stan used a similar rpm or close too... maybe he had a bit bigger because the alternator pulley in the picture seems a bit less than half the driving pulley... mine is half ...


more will come

You will need to use frequencies in multiples of your flat output.
Example,
If you put a flat 12v through your rotor and you get 1250Hz, then you should hit your rotor with say 5000Hz (AC) this, when rectified will give you the wave form you are looking for.
Also if your motor starts to slow down this is because you are pushing out amps, if your doing this then your moving away from the method described. Alternatively you can send a FM tranmission through an AM transmitter, or visa-versa. This will give you greater control over your output frequencies and the amount of amps you want to use.
I suggest you look at 200-2khz for you primary then 20-200hz for your secondary (numbers based of the AP patent 4394230)

problem is that the motor is not able not eve to charge the battery... it turns too fast...


i went down town today to find a motor but didn't found a good one yet...


i will get one 1800rpm 2 hp so i can use the same pulley witch costed me already bit.. probably i will need to machine it again to adjust to the other motor..




Actually the alternator is putting out the unipolar pulses at 1140hz... when i pulse it it mix the frequencies... i have a distorted unipolar pulses...




I thought about making it resonant adding a capacitor so as to be able to reverse the polarity of the field poles,,, it has a reminiscent magnetism witch don't allow the field to reverse...


i found a variac like 1,5kw for about 120 euros... there are ten of this... they are used.. was from a fabric... i would like pulse the field coil with the unipolar too 120hz witch i think that is important because is a multiple (or almost) of the 1140hz

I tried pulsing the alternator and got the following results... (using the same 1/3 hp motor)


Battery will charge if i pulse the field coil and the driving motor fell very little change in speed... i can pulse it from 10hz up to 100khz ... pulsing at 10 hz i get the battery charging a bit charging more than is discharging.. the field coil at this condition have 11v and 260ma 10hz...


If i raise the frequency, the amps get down to almost zero..


when i'm higher than 10khz the amps start to raise and can reach up to 1 amp close to 50khz... at about 700ma(field  coil) the battery get 13,5 volts charging and the motor experiment a bit of force...(slow down just a bit) if i get up to 1 amp it experience big force...


Conclusion : will keep working =) with this motor for now.. .


Strange is that using the voltage regulator the motor will not keep turning... but pulsing the field it will..


I think that at higher pulsing frequencies the field coil or my pulsing circuit is not able to completely reverse the field thus maybe i'm getting dc on the field coil... but i'm not sure... my meters are bit crap...


What do you think about?

The rotor (field coil) has a certain resistance, say 3 Ohms for mine, so under a DC voltage the total impedance is just 3 Ohms

When you start pulsing the rotor (field coils) you create inductive reactance (impedance), which is proportional to the frequency. Higher Frequency = Higher Impedance.

The pulsed frequency effects both the rotor and the stator, increasing the impedance in both, and then reducing the amps.

If you find the self resonant frequency of the Stator then impedance will be a maximum, and you will restrict amps to a minimum.
