Maybe you need more time. I also spend a lot of time and money, but I know that once you learn it will be easy and you will wonder why others have a problem with it. As with everything in life.
A great mystery where this power comes from. What does he do. It seems that it has a big relationship as it is not the only one with back-emf.
When the coils are always on, there is no back-emf, this is a good direction. So change the intensity and maybe it will not be back-emf. I do not know, I have not tried it yet. Maybe someone would do a simulation in FEMM.

j'ai oublier de préciser que le générateur est non charger pour les tensions dont je donne un exemple ,il n'est donc pas question de back=emf dans ce cas ci .cordilement Mosha.
EN:

I forgot to specify that the generator is not loaded for the voltages which I give an example, so there is no question of back = emf in this case.

Hi all
My friend Gary Porter just tested his version of DZ generator, and like everyone else so far he got measly voltage and power out of the locked rotor windings.
He thinks why this is so. Is because the rotating field windings do not cut through the locked rotor windings as they should at
90 degrees. Something to think about and correct somehow.


R2flp:
That is really good idea the two coils each end varying their intensity in place of field rotation.
Perhaps have one end coil be much stronger than the other, and then flip it have other end much stronger...
Have one pushing through while other pulls and try to get the pulsed flux to travel full length through fixed coil in middle.
Also perhaps just energize end coils just at rim and edge of fixed middle coil create a sort of tube of alternating flux that.moves back and forth around the fixed middle coil...
Anyways really good idea..maybe Pierre is doing something like this each step of rotation too...



To all:
Perhaps a simulation of Lenz law forces is needed in the pulsing scheme....some sort of resistance to the flow.of rotation because without resistive load in rotating generators you will make zero power and so that is what people get so far...maybe this Lenz law simulation could be brief bucking event after every step or every pulse not sure just thinking whatever this could be
Could be the polaritynoverlap of the steps in rotation could be pulse polarity reversal could be both or something else

That's flux cutting he is talking about. which is not possible with this geometry. Discretely switched fluxes do not move through space and so they can only flux link.

Indeed, this device is a flux linking device, not a flux cutting device. The only way you could possibly turn it into a flux cutting device is if there is no iron in the output coil, which is clearly not the case as Pierre has stated in his videos that the output coil is wound on a iron laminate core.

Hi All
Here is email I just got from Gary Porter, and a couple drawings too:

"I figured out what he did and it matches with his pulsed sawtooth and BEMF spikes. The attached pic shows one circuit of the 36. I need 72 FET 36 for GND and 36 for power. Your right the odd coils are versed polarity to get South poles. So their are 36 coils I found that with my stator slots I can have a max of 34 17ga wires so two coils at 17turns each will just fit the slots. I'm about half way thru inserting the 36 coils man it is a pain I have to put one wire in the slot at a time and near the end I have to push them down into the slot with wood.

I'll have to redsign the PCB into two boards one as a controller and 9 others each having 8 FETs. The Arduino 2560 has 54 digital outputs so I'll have to use 36 of them twice to get 72. so each pin connects to two buffers each have an enable line.. Pierre did this on his control board look at his top left and you'll see two FET by themselves. These provide a ground path each of his 36 relay groups. He uses 72 diodes to gather BEMF positive spikes only that's why his waveform has so much negative noise after each relay is opened.

I want the sawtooth with noise to pass into a 1:1 transformer cap on primary for 60 hz resonance. this should clean up the signal."

Focus on creating strong magnetic forces at specific points in the rotating field.  This is the variation and intensity.   The stronger this field changes is as it rotates, the STRONGER the opposing field (armature output) is created! Remember the variation and intensity is very important.   I believe there are additional coils in parallel at the same time at specific locations. Look at scope shot.  He shows groupings in his 5th video.   Look for it, you'll see it, look at the pencil drawings.  Pierre erased them in arcs, then placed them with lines over the top of slots.  The lines show specific locations.  Look carefully.  The lines are parallel with specific fields!  This has to be important!

When creating the rotational field, you can do this several ways.  But the fact is you have to think in step action as the fields rotate and we know Pierre did it with 6 poles in rotation.  Each 6 pole is a step action and an isolated group.  However, the coils are in parallel at specific points with others to increase intensity and variation. You DECREASE inductance and increase CURRENT because of this.  Inductance is changing in rotation!!!!  This is VERY important.

In the beginning, Pierre had all of his coils in series, and had very little return.  He knew this and had the same problems we are learning about. He later placed them in series and parallel and each group is isolated.  Pierre even states in his own words, to not cross the fields, they will cancel and reduces your efficiency.

Read these posts carefully again.
