Muller Dynamo

[Thaelin]

Stephan:
   On the question of the hall sensors, you need to have two. Each coil pair is in a different area when using 9 coils. If it were eight, you could but you would have to have even coil/magnet pairs and lots of cogging. I have 9 coils and 8 mags and if I hook up one hall and both driving pairs to the same transistor, it stops.

Tach here and have 750 rpm with one coils set driving. Getting ready to switch over to fet pairs for the drive. My cap will give me aprox 5 seconds of unloaded dc-dc regulator. Not good enough yet. Also getting ready to loop the flyback of the coils to the input side cap via dual diodes.

Regarding the 2 Hall sensors Romero used and what Ben just mentioned:

It still puzzles me, why in the world did Romero use 2 Hall sensors and not just one to control the switching of both driver coil pairs?

Normally one Hall sensor should be enough to control this,right?

You see, the motoring coils are nr.1 and nr.6 The angle between those coils are 200 degrees. (360/9=40. There are 5 spaces between each coil, each space has 40 degrees, equals 200 degrees) On the rotor he got 8 little timing magnets each has a 45 degrees angle between them. We got 180 degrees between timing magnet nr.1 and timing magnet nr.5. So, when a timing magnet is in front of hall sensor that drives coil nr.1, the angle between the hall sensor that drives coil nr. 6 and the nearest timing magnet is 20 degrees. The conclusion: the motoring coils never fire in the same time due to the odd-even configuration between number of coils and number of magnets of Muller dynamo. Excuse my empirical math and my poor english. Hope it helps.

generator coils :

"Below is a picture with the scope connected at the AC point before bridge.
Answer: I run out of neo magnets. I am sure that more magnets will increase the output. I have ordered more togheter with the magnets for the new setup."

I think that if I have 8 magnets on the rotor and any other greater uneven numbers of coils will work even better.
What I found durings some tests is that we need to have good spacing betwen the magnets on the rotor.

Motor coil
The OFF time for the coils must be much greater than the ON time, possible because of the  core I use.Better material for the core will improve substantially.
People should pay attention for the core material, that is one of the most important keys in this setup togheter with the spacing arangement.
I will try different configurations, now that I made note of everything I can do any changes and still able to go back to the curent setup.

Generator coil
Something I discovered yesterday is that if I lift the magnet on top of the coil just a little bit then the output is increased. That shows me that I need to take every magnet and check, lifting up and down and add some spacers if required."

"I am busy with so many things going and it is much easier to answer questions than having all answers in one document. There are many people ou there who can do that if they wish and I can do corrections after that.
I had a question about why is one sensor on the side and another one on top of the big magnets:
After trying all different positions I got is running like that and I have not tried again to have them using the same spot. It worked then I moved on,... thinking to go back but later having nice results I didn't care anymore.
It works in attraction mode... maybe the bictures below will help."

"The generator coils experience cemf depending on the load but at some point the speed goes up now down.
People should see the whole picture, don't look at a single coil, look at the other coils too at the same time.
Looks that we have a member(Microcontroller) that is 100% sure that this is a fraud, ha, ha, well u got me "

ferrite:
"I have used them in some other projects and worked good. Best will be mumetal or simmilar but the price is huge."

"Hi,
most of the questions have answers already, please read all posts... I am tired to just answer same questions hundreds of times.
The coils are 1cm usable, the inside between the ends, in total 1.2cm and diameter 2.2cm
the core ferrite 1.5cm/6mm diameter.
I have tried without cores but less performance, higher speed but low output.

I will not do other videos, this way, everyday I will find someone to suggest something else.
For all replicators.

After some tests today and changed one pair of coils, same type of wire but 1.5cm diameter ferrite core, 1.5cm long.
Still 1cm winding space on the coil on 3.5cm diameter coil.I have doubled the number of turns to 600 for each coil.
This was done just for one pair of coils, recovery not driver coils.
The output is increased  but for more I will need to change them all to balance the system but  I wont do that, is to much unnecessary work, I wanted to check and apply to the new system.
Don't even think of using metal or laminations for the cores.

I had another request to sell it. I HAVE NO INTENTIONS TO SELL IT. - please no more."
“To get to the point where you will get even a little bit out than in requires a lot of time and work. Check every part of the system, part by part, then when you think is tuned start again.
Let me give u an example:
If u have 10 parts in your system and after jumping from testing  the first then second up to 10, when u finished you start again. It can be that part 3 is not as before after u adjusted any other part after. Once you retried everything and got best of all adjustments then you are nearly there.
Do all this testings without having the rectifiers connected together.Measure every coil separately. Even if you don't get too much out from the coils, don't worry, when all are connected things will go magic.
A DC/DC Converter is a must.
Don't rush, I have spent about a month to get here.
Once u past the point and for 1 you get even 1.1 then things are easy
Success!"

   Open circuit coil acts as a load appereantly. However dead shorted circuit coil acts more like magnetic flux capacitor (or mechanical spring) and has little losses  and unloads prime mover so one can see acceleration.  Now in your video you might tend to think that shorted coil provides acceleration. This is just illusion. Its easy to figure this out by measureing rpm with shorted coil and then measuring rpm with coil removed all together. Removal of the coil will provided greater acceleration or increase in rpm then the one shorted. So no free lunch there. And why would open circuit coil act as a much greater load than shorted I am not sure (oversaturates?). All this I have observed with my thane heins replication. As far as I am concerned his theories were wrong. Just my opinion.

My first thought was also, "this is Thane Heins effect"

I know this effect well as I personally work with Thane.

The only way we could take advantage of this effect is if we could somehow get the magnet rotor turning freely as if there was no generator stator core there.

If anyone can solve this one then you will produce OU free energy.

Okay, thanks for clearing this hall sensor timing up.

Would like to see a scopeshot from a dualtrace scope of both hall sensor pulses over time over a few cycles.
This way one could see better the relationship between these fire pulses and when they exactly occur and how they could be tune better.

If you have a 4 trace scope please also include output DC Voltage and loopback output current on a shunt so with these 4 traces on a scope you can probably tune the hall sensor positions optimally for maximum output.

So I guess it really needs at least a 2 to 4 trace scope to optimize this device more easily.....
