Hi All,

I was very sceptical about this whole setup but thought I would give it a go and see what the outcome is, I see that many people have also made this setup and not succeeded in getting any reasonable output from the unit.
I have not given up with it yet but my observations of the whole topic are as follows:

1. Pierre posted a video showing his device producing 100+ volts output.
2. GotoLuc made a similar setup but with only 30 slots instead of 36 - I personally dont think that the missing 6 slots in the stator would make so much difference.
3. Pierre released a copy of the source code which was copied, this code also appears to be the same as that used by Pierre in his original video, in as much as the LEDS are looking similar.
4. Pierre produced drawings and after examination by people following this topic it was decided how to wire the stator.

In my opinion members of this forum have reproduced devices close enough for somebody to have found a result, then Pierre states that all these copies have just produced a rotating field and that the "pistons" are missing, and saying he has withheld some vital details, This cannot be the case as the reproduction has been done pretty faithfully, in so far as the rotating field etc, same LED Sequencing etc.

I think that returning the energy back to the caps, while it will help with the overall efficiency is not where the "secret" lies. We should be able to reproduce the high output voltage without the energy going back to the caps, although we would consume more current.

Obviously if we put many many more turns on the block (fixed rotor) we would increase the output voltage, but, this would then be just acting as a transformer.

I have a few questions which may be useless but they may cause a Eureka moment for someone else reading them.

1. What is the Orange material in between the rotor and the stator? Is it paper or some secret thing, if I put paper between my rotor and stator my low output voltage becomes even lower, but in Pierres video the orange material is in between his rotor and stator.
2. When using a switched mode power supply to feed the caps it will attempt to regulate the voltage of the capacitor bank, or at least my one did, it was necessary to add diodes in the +ve and -ve lines to prevent the psu from regulating the cap bank voltage.

My output voltage is very low, attached are some pictures, 1 of my setup and 1 of my voltage output waveform and 1 of the motor I used.

Wow, great job dhodge
As far as I can see you have done everything right based on the information that has been provided.
Hopefully Pierre will come back before the end of the year to show his improved DZ version 2

Thanks for taking the time to share your result even though they are similar to what replicators have achieved.

Forgot to mention in my post that I actually wired the stator 4 times and differently each time before settling back to the original one which is 36 slots each coil with 6 slot span, so all slots have 2 windings in them.
Have both ends of each coil out to terminals so can swap them at my leisure, spent weeks trying so many different permutations of the coils to end up no better off.

I honestly did not believe it could possibly work but thought I would give it a go anyway, unfortunately I am still not 100% sure that it wont work but above 90%, I hope for the sake of the planet and all the other things that go with it that Pierre comes along with the answers and follows it through.

Just for information,  I had variable delays which could be entered into a web page on my attempt at the DZ generator, all of the Bridge boards were switched using SPI Port Expanders so only using a few IO Lines of the processor.

The coil switching was as in the below file, just to explain briefly there are 2 times set from the user interface, 1 is the overlap time and called switching_delay, the other is the coil running time - pulse_duration,

This is to say - coil on for pulse_duration time, then next coils in sequence are switched on and this means both sets are then on for the switching_delay time, then the first coils are switched off - that is to say the 2nd set of coils are on on their own for pulse_duration time. ( This is hard to say in words )

The xStepMode part at the begining of each step allows me to pause the sequencer and step manually, This is mainly for checking wiring for shorts (had 1 in the stator at some point) and correct direction of pole (N/S etc)

Only really posting to share information, if anyone sees any "deliberate mistake" it may be helpful. Coil notation is as in the connection between coils, eg COIL_1_2_HI means coil1- and coil 2+ connected to high power supply, COIL_1_2_LO is the same connection but to gnd, COIL_1_2_OFF means floating (Subject to body diodes).

Switching pattern should conform to the picture below (Taken from elsewhere on the site)

The time delays are accurate and can go as low as 50 microseconds, processor running at 150MHZ and program is compiled from C.

Hi DHodge,

Attached is about the best I achieved with the BTS7960B bridge boards. In this test I was using a linear power supply so the power in measured  was on the AC secondary.
If you look at previous posts, you will see that in the case of the stator I used for these tests, the flux wanted to couple across the teeth not so much across the rotor.  I modeled the stator thickness ratio based on Pierres stator and this then ensured most of the flux crossed the rotor.The orange material is just plastic packing to stop the rotor rotating/vibrating.
You wont get enough current through the 5 or 6 coils in series, to achieve any more output than I have shown @25V DC input. Pierre later stated that he used parallel/series coils to overcome this limitation.
The BTS7960B bridge  boards can't support the voltage boost function. I modified a couple to achieve this with additional diodes, but their voltage rating is too low for the voltage boost at 25V DC input, which is about 45V.
I have solved this with a discrete design H boost bridge.

Pierre showed the boost circuit as a separate schematic however, it really needs either a parallel or parallel/series coil arrangement to work and  different code to run it.
So there is much missing from what Pierre has shown.
