Alternator vic.
« on: June 15, 2011, 17:59:02 pm »
i have reassembled my alternator setup and have performed some tests..

I am getting unipolar pulses out of my cell.. the way i have wired my 3 sets of wires per phase.. i wired them to match  Dons sketch of stan's 5 coil vic.. 

here is 2 pics of the wave i am getting at the positive exciter


the first scope shot is just a lower amplitude..
The second reminds me of the scope shot that Don shared.. The one with the electrical polarization process.  these scope shots are taken with just the probe.. the ground lead for the probe is disconnected..
for some reason when i save these on the scope they dont have the data showing the amplitude and frequency.. i will take regular photos today..

there is also another configuration that is allowing unipolar pulses that are not crossing 0... will post more later

On a side note, I have 2 stainless steel plates around 7 x 7 inches in area each.. i have them in a cooler thats around 2 foot in length and 10 inches wide..   i have the plates set in the cooler so i can vary the distance between the 2..  up to around 2 feet... i connected a 100 ohm 25w resistor to ground then to the plate.. i connected the positive battery source to the other plate.. I put the positive lead of the voltage meter between the plate and the resistor then i put the negative lead on the batter ground....

When i vary the distance of the two plates in the cooler i get a change on voltage reading between the resistor and plate.. 
 If I use a 12v battery and a 100ohm 25w resistor what do i need to do to set the gap to match the 100ohm resistance?
 I must vary is spacing of the plates to vary the resistance between the gap.
 by adjusting gap spacing i can adjust to where the voltage meter reading between the cell and resistor reads 6 volts..  when the meter reads 6 volts thats when the cells resistance and the resistor are matched.. since this is simply how a voltage divider performs..

this is a good way to maybe a high watt resistor! one that will never burn out. or will it..   lol

good stuff

i don't see the diode blocking pulse in your waveform like i see in mine, also one of your phase pulses looks bigger than the other two, why would that be?

i calculated from one of my waveforms that the alternator and cell would resonant at around 13 kHz but I have not pulsed the rotor yet to try that

the way to calculate it is after the diode blocking pulse the coils ring, like it's striking a bell, this ringing frequency is the natural res freq of the system
