Hi all, Hi shylo, thanks for the reply, are you going to experiment with this setup.

Yes it is 11 strands and 1 strand for feedback, using it because I have it on hand from that previous project.


I assume a single strand will work, since the original south african developer used 21 awg. single strand in all coils in the most preferred version.

I have to go for a couple of days, though I have a small data sheet already, will continue testing when I get back.

Here is the data so far, realize, The setup has already been running for at least 15 hours previous to this data sheet.

Quote
South african self powered generator test using two 12 volt tractor batteries.
Using only one coil/core at the moment, 12 strand 24awg., ferrite tube core.
1 kohm base resistor, TIP3055, 1n5408 diodes for base to emitter and collector to emitter,
2 parallel MUR460 flyback diodes.
3-1/2" diameter rotor using 1" diameter by 1/8" thick neo magnets, 4 total, one per 90 degree position.
=========================================================================================================

Have already made at least 5 battery position swaps and at least 15 hours run time.
Input power from input side 12 volt battery is around 3.23 watts,
or .26 Amps at 12.435 volts average or 48.45 watt hours so far.

Each battery, Battery A and Battery B, one had 12.55 resting volts at very start of these tests
and battery B had 12.56 resting volts at the very start.

Continuation of testing now documented - Test Battery Swap #6:
-----------------------------------------------------------------

Battery A overnight rest voltage = 12.57 volts
Battery B overnight rest voltage = 12.70 volts

End loaded voltage charge side Battery A = 13.40 volts
End loaded voltage input side  Battery B = 12.35 volts

Run time for test #6 = 4 hours 24 minutes


Test Battery Swap #7:
------------------------------------------------------------------
Battery B 1 hour rest voltage = 12.56 volts
Battery A 1 hour rest voltage = 12.75 volts

End loaded voltage charge side Battery B = 13.14 volts
End loaded voltage input side  Battery A = 12.35 volts just blip to 12.34 volts

Run time for test #7 = 3 hours 17 minutes


Test Battery Swap #8, This test will continue when I return home
------------------------------------------------------------------
Battery A overnight rest voltage = 12.57 volts
Battery B overnight rest voltage = 12.695 volts

Hi, I've done some tests regarding the charge output for a secondary battery. It's not a circuit that meets your eyes. There's an old story about what I'd like you to read. In this matter has 3 very simple schemes to put in the recharge. Good luck with the tests and keep posting. Force
http://www.thetruthdenied.com/news/2014/03/12/radiant-a-suppressed-fast-battery-charger/

I know that in relation to the project is not directly a radiant charger but the pulses cause this problem in the secondary battery.

Hi aldex, I'm back, thanks for the reply.

Yes, I've worked on the stingo circuit previously, it is a nice charger.

Though the device being worked on in this thread, will not cause fluffy surface charge in any of the batteries, If that is what you are alluding to.

Any flyback voltage is coupled with the input side battery, same as boost converter and this gives the higher current charging, also generator action in coil caused by rotor magnets is coupling with input battery and giving charge to charging side also.

I have continued testing.

Hi all, I'm starting a new test, charged one of the batteries up a little, didn't need much anyway, because this setup does not seem to drain the batteries at all.

I was fiddling with adding the other coil and wired the feedback wire wrong and caused large current draws for a bit that would skew my long test run, so I'm restarting it.

Also changed the transistor to an NTE331 NPN, it has a little higher gain and I have the input tuned to around .340 Amps

Will be sharing the data, as I collect it.
Will be adding things to the setup after this testing.

Hi all, just a small progress update.

It seems the tuning of the feedback motor trigger coil circuit, needs to be tuned correctly, or the primary coil will most likely oscillate when we don't want it to or not give optimum charging efficiency.

This may cause increased input and the self sustaining battery charging will not be present.

We want the primary coil to trigger only when a magnet passes, just after top dead center.

So I raised the base resistor to 2.2 Kohm to reduce input current, still using NTE331, the rpm's reduced, though not that much.

I also added 3 more diodes (6A6) in parallel with the 2 other MUR460 flyback diodes to lower resistance, since I noticed the 2 MUR460 diodes were heating a little.

And I again started a new test, The input is even less than it was with the TIP3055, around .21 Amps and the rpm is higher.

I'm keeping it simple at the moment, to figure out the best parameters, so that It can be scaled later, for more useful shaft power.

Hi, I'm also waiting for a material to arrive here that I ordered to do a new assembly. this African generator is similar to the adams engine but as it is supposed to have no information on the internal measurement of the coils it is difficult to replicate since with the identical interiors it does not work as several people have already tried to replicate. I'm going to start my assembly I believe that next week using these configurations but using the adams principle together because I believe in his design a lot. Already having some result I am passing you. Have you used tip 35c? I used it on some tests and got as good results as tip 3055

Hi aldex, thanks for the positive reply and the fact you are testing also, glad to hear that.

I have not tried TIP35c with this setup, though I think most transistors will work, as long as the current gain is high enough for the coil being used with the feedback trigger version.

Also, the base resistor has to be tuned properly, because too much base drive causes the increased input and the charge side battery does not seem to maintain it's charge level.

As far as using a hall effect sensor, that may be more reliable, meaning easier to tune and no issues with possible run away self oscillations which can happen with the motor feedback coil setup and I do have hall sensors on hand for later possible use.

Would love to hear about the results you are having, could you share any pics or circuit drawing.

I'm continuing testing with the TIP3055 again.
peace love light :)

Hi all, here is an odd observation, after using the NTE331, I found with my setup as it is, the TIP3055 works the way we want, it seems to keep the battery charge up.

I had another TIP3055 on hand and used that and the motor would not rotate, using the 1 Kohm base resistor and only rotated when using a 500 ohm resistor and drained the input battery and did not charge the charge side well at all.

I checked both transistors with the meter and both seem good, only difference was the number shown on diode setting on meter was 100 more for the transistor that works with the 1 Kohm base resistor.

With the good TIP3055, rotor euns at good rpm, draws low input current and charges the charge side battery quickly.

Something must be damaged about that other TIP3055, I don't know.

Now I have to restart testing again, It seems finding the right transistor is important, I know the inventor used the MJE13009, which is a high speed switching transistor, I may need to order some of those to try.

Hi all, not much forward progress yet on this setup.

Though I realized I needed more transistor base drive, as this coil is 12 strand, so actually not that many turns for a single strand.

So I used 2 strands in series and that is giving strong base drive now.

Had an NTE52 NPN on hand and that is a high voltage, high speed switching transistor.

It seems to be working very well at the moment, giving good rpm's and about the same input as the TIP3055, am continuing testing with the NTE52 transistor.

Hi aldex, yes, I'm building a bigger model, using a 12" aluminum bicycle wheel, though the actual rim diameter is 8.6", waiting for wheel to arrive.

In meantime, I'm making the coil/cores and coil holders and support structure.

Already have a core done, using 16 awg. bailing wire (black annealed wire), cut to length,
many pieces to fit in plastic pipe.

Spray painted the pieces to reduce eddy currents.

For core holder, using 1/16" wall thickness, 13/16" diameter pvc pipe, used for water heaters, from menards.

Have rectangular ceramic magnets from previous projects for placing around the bike wheel.

Reason for building new setup, the first one was not following the south african design much,
at least this model will be closer in design.

As it comes together, I will post pics.

peace love light

Hi, I received my magnets for the beginning of the tests today. tomorrow I start to motar. I bought 20 neo 20x3 and put 4 on each end. respecting more or less the parameters of the project. What's new in 20x3 fashion is not even half the magnetism in the size of the reels that shows the photos of the project. (it was not achieved as this project was successful) I will strictly respect the magnetic field and the size of the magnets for manufacturing and cores of the coils. So send photos as photos. I'll see what happens.

Hi aldex, thanks for the reply.

I think one of the main reasons for using the weaker ceramic magnets, is the saturation of the core,

as too much flux would take more power to overcome and switching times might need to be longer,

which could reduce the higher efficiencies we are seeking.

And here is a picture of one of the cores so far and the bailing wire I used, the ceramic magnets that will be used and the coil former end piece template.

Hi all, here is one of the coil/core assemblies finished, just need to wind the coil.

Going to wind a 24awg. bifilar coil for the main primary-feedback coil, as I have that wire on hand.
