electrical connection using generator Stirling

[jsdu19]

hello everyone, I made a small Stirling electric generator but now I have a little problem for what I need to do to connect it to a battery, I have a level close to zero in electronics and electricity but I would like well do everything by myself if not it is not enriching. I saw on the web all kinds of plans to achieve charge regulators if this is what it is necessary to do ... but I completely ignore what to choose for a Stirling generator. The stator consists of 18 coils, 77 turns, gauge 21, the rotor 2 flywheels in mild steel with each 24 permanent magnets 30x10x4 mm N 35. Sheltered from all drafts with a culinary alcohol burner I get a regular production of about 20 volts, for watts I do not know, a specialist may be able to calculate that, a 12 volt bulb 28 watts lights up by turning by hand. You will understand that I only have a practical sense (I do, I observe, I remedy as needed) I have great difficulties in understanding mathematical formulas, if you can explain it to me in a profane language of photos and drawings I can move forward in this little project. Here I thank in advance all those who will have the patience to look into my case.

So first, well done for your achievement. I'm a fan of stirlings.
as for your generator, you must first test its characteristics and those of the engine a bit to find out where you can go.
I suggest that you work with two multimeters and a set of 12V bulbs
you start with 2 bulbs in series with one of the multimeters connected in Amperemetre mode. the other multimeter measuring the total voltage.
when your engine is running well, you plug in the circuit and measure current and voltage.
then you add in parallel with the bulbs another set of 2 bulbs in series and you repeat the measurement. etc

hi dirk pitt, glad you like and bring me your help, i have no one in my immediate entourage who had a multimeter to lend me so i try with only one if it can be useful? at around 16, 17 volts in my garage by making contact with the black plug on the wire of the 12volts 28 watt bulb I get between 2.7 and 2.9 (switch on 10A) for 1 second and the engine freezes net. I repeated the operation several times

a 28W bulb making too much current demand at start-up.
you would have to try with a weaker bulb of the style a bulb of your spare box of car. that of the rear pilot lights is generally 5W. you try, you measure and then if it fits you add a 2nd identical bulb in parallel.

it's nerd I don't have that in store I move on 2 wheels. By cons I came across a very interesting video on youtube https://www.youtube.com/watch?v=P67QOG07yfI , the gar obviously uses a charger for the solar (for a few euros on aliexpress), I rather saw a wind charger but as it costs the skin of the buttocks I thought to do it by myself, what do you think?
