I will look for a small charge controller then first. The one I have at the moment is for the full 48V Battery array. It cuts in (starts relaying recitfied power from the 3 phases of the alternator to the array) at 54 volts and hits the breaks by shorting the 3 phases at 60 volts.Stop right now.
Ohh no my dear borther, I never meant to purposely destroy a cell. I meant in the pursuit of science I am willing that as a potential outcome. I would rather keep the cells happy and usable if I can avoid destroying them.What's the point of trying to trash a cell?
If the cell is empty you probably can't hurt it. If it is full you surely will.
But sometimes risks need to be taken else risk stagnation of knowledge.
Nothing more interesting than you could do with your bench power supply, and you could do that while out of the weather. No need to punish your cells. Your MPPT charge controller is essentially tasked with finding and matching the impedance of your charging source. For solar, that might be anywhere from 1 to 20 Ohms depending on the panels and actual solar conditions. For wind, I suspect that it will be a similar situation, but probably not less than the DC resistance of each coil in the alternator.Then running this experiment could provide interesting data?
ahh yes, liberating words!!! I am so happy that I reread comments from time to time as I normally am not able to process al relevant information on the first pass through.Before cell becomes full, it will act as a shunt regulator and clamp generator voltage to what the cell wants.
Yes brother, Guy wires are going to be needed once I have got municipality building approval for my master plan. It will have a 7 meter diam.Guy wires from the top.
Yes sir, I will get on that!I would think that open circuit voltage and short circuit current would be interesting measurements to take at various RPM. If you find that you can't turn the alternator fast enough with it shorted, that's good news since you are producing plenty of current. In that case, find a load resistor and take volt/amp measurements at various RPM.
well in that case, I have no problem comming back to the 3.2V test. This time around not to see if a cell can hold voltage, as we are already assuming it can, but because you show interest in data.I would think that open circuit voltage and short circuit current would be interesting measurements to take at various RPM. If you find that you can't turn the alternator fast enough with it shorted, that's good news since you are producing plenty of current. In that case, find a load resistor and take volt/amp measurements at various RPM.
Well, you have already suggested it I think I remember. So all I need to do then is find a submersible water heater then. Here in my house hold we are all electric, no gas involved. We have a 500L water buffer that is doing it's job quite nicely to store energy (heat).In that case, find a load resistor and take volt/amp measurements at various RPM.
I was assuming he doesn't have any diodes on his alternator; I thought we were talking about basically magnets and coils of wire.Do not let it go open circuit. The voltage would go high enough to kill the diodes.
Excess current will also kill the diodes with heat. An alternator can put out high current for a limited time. The three diodes for positive fail first because heatsinked to a small plate rather than chassis like the negative.
Best to connect to the three wires, short them for an AC measurement, use external diodes for continuous load.
While testing, you could connect the rectified (by internal diodes) connections to a car battery. That will clamp voltage to about 15V if your test connections come loose.
@Justaguy @Hedges @Warpspeed @curiouscarbonUpdate.
@Warpspeed I was mistaken. Earlier I said that attracting fields does not double the flux but it actually does.
First when I said that I was quoting some random source online.
But then I went and tested it for my self and I stand corrected.

i used the top right print to measure it with my tesla meter. THe little circle in the middle is where the measurement tip went.
in the lower left we can see a test rig that I am printing to test a few variations on magnet arrangements.
I am slowly beginning to believe I have been at this all wrong all the time.
In where it is not about the frequency of magnetic field reversal that is a component in
e = b * l * v
There is no frequency component in that equation.
So I am going to take my sweet time to trail and error and see if my spre4adsheet holds up. I think it will give get me close enough

One thing I do not follow yet in theory is why would a coil running through to attracting fields produce any electrical flow?
@Hedges can you take a stab it this? this is basically what @Warpspeed is suggesting to do.
But in my books it will just result in a theoretical 0 flow of electrons.
BTW. the tesla value was goal seeked. As my tesla meter can't be used to measure the value for an area. only for the spot it is placed at.
@justgary I meant to include you in the above, I messed up a bit ;(@Justaguy @Hedges @Warpspeed @curiouscarbon
I am hitting a low point in my motivation at the moment.
Does the above formula actually need physical scrutiny? Or can I just skip a corner and assume it is correct and get this show on the road far faster that way.
I mean if it is correct than it is almost trivial to build a 54V output at like 20 rpm (and rpm that aligns to what my specific wind conditions / turbine can produce with ease)
If all of you say that the lenz law does not apply here then I will plow through and get some hard data.
