Muller Dynamo

[mondrasek]

Update from yesterday's testing:

Working with load resistances below ~50 Ohms causes some metering issues.  At first I had noticed that placing the meter + probe on the Vin to the motor drive circuit caused an RPM and subsequent Vout increase.  This effect turned to an RPM and Vout decrease at the lowest resistance of 37 Ohms.  I did not check along the way.  But a couple data points before that last 37 Ohm resistance test I began to notice that measuring the Vout across the resistance was also changing the RPM slightly.  So each data point was skewed by how long I let the meter linger before writing down a reading.  At first I thought the RPMs were drifting up and down at each resistance setting being tested, but I confirmed that the RPM was stable if I did not introduce the meter.  The resultant graph of that data is a mess due likely to the unnoticed RPM changes the DMM was inducing.

At 37 Ohms I did my best to "tap" in with the DMM as quickly as I could to get Vin and Iin for another input power data point.  I added it to those data points taken previously from no load down to 50.1 Ohms and like what I see.

The jump in power ratio occurs at around ~1850 RPM and below (how low it may continue is yet unknown).  Since I have RPM control of my drive motor I will test how the system behaves using some higher resistances and adjusting the RPM down to that range by lowering Vin to the motor drive circuit.  Hopefully this will be a way to locate the optimal load as well as see if the effect appears at different RPM for different load.  My instincts tell me that the effect is RPM dependant and not load dependant which would make further tuning easier so I am anxious to find out.  If the effect also stayed at the same RPM when the gap between coils and rotor mags is adjusted that too would be a pleasing find.  That would indicate to me that the effect appears at an RPM that is based on the geometry of the rotor and would be a calculable design feature.

This was posted over on Professor Jone's topic.  It was copied and pasted by him from OUR forum.  I thought some folks here might like to see this.

Please  leave Muller daughter alone, there is no connection at all with her in  what happened, it is only my fault, I should have  kept my mouth shut.
I  respect her for what she does and follow her father work. How many  ladies we have in this field??? very few and that makes her special.
She has also encouraged all to try and replicate the original Muller Dynamo.

The  device I built was not 100% Muller arrangement only even/uneven magnets  and coils, even that was not as Bill Muller sugested, I should I had 8  magnets and 7 coils to keep it to the original.
I will not comment that device anymore, fake is fine if is not is fine too.
I moved away from that device, why don't you all  who believe that is only a simple dynamo move away too?
There are so many other devices that can be replicated, many of them much more easy and cheap to be built.

Best regards,
Romero

this was nothing compared with other devices already discovered and presented recently.
The future energy is not going to come from any devices like this, this one had a lot of problems and had a lot of limitations.
If  you consider that me, SM, Kapanadze and others are  betrayers of  mankind what will you do? It is so easy to talk when you are not in my  position.
If you have to chose between you and all others what will  you chose?. In an ideal world 'maybe' will chose the others but this  world is far from ideal, we are all struggling, including me.

Well I started putting the motor back together and was able to test run it briefly. The new drive coils are coming in at 2.1 ohms in series and this is causing issues with drive circuit, wants to pull way to many amps. Smoked a tip42 in less then a minuet....lol. Anyway I got to go home early from work today and will be heading to the garage to see if I can get something to work. If all else fails then I will be going to an Arduino controler, to control pulse length and that should cool things off a bit. Will keep yall posted.
Peace

Hi Scratch,

can you tell us more about your latest video?

How were you able to achieve the waveform ?

Is that only one coil?

Is the rotor setup as 2x mag spacing and NSNS or NNNN?

Hey Penno, I tested with 2 coils in series, one is mounted under the rotor but I think the distance to the rotor is to big, the other coil I hold in my hand above the other coil.
The circuit is just like in the pdf, 2 coils to a FWBR(I use a KBPC3510) with extra diodes but without a load. When I put a load I get drag but with only the big 5 x 15000uf capacitors in parallel almost no drag, the waveform is taken over an 1ohm resistor between the coils and the FWBR. The 8 magnets on my rotor are very small, 10x5mm and are all NNNN

Maybe the FWBR in combination with the Caps create the switching and because of that there is almost no drag, the Caps absorb and the more they charge the smaller the drag. The drag I get is nothing compared to the normal drag with a load. Maybe the size of the FWBR matters? Maybe it can miss some energy to pulse a coil now and then

Maybe this thread is going in the wrong direction and making things to complex.
