Muller Dynamo

@teslaalset

Your simulation results are very interesting.
Please open a separate thread, so you can post more of your findings.

May i ask, if you also have a possibility (or maybe you included it already)
to simulate the soft iron washers' effect?.
There is controversial opinions on what they do. Some say they
focus the magnetic field through the whole in the middle and some say
they would even spread the magnetic field more out.

Keep it up

It is very important to understand that the exact adjustment is done under a specific load.
If the load is changed after adjustment, you will lose the cancellation of the BEMF forces.

What do you mean? RomUK has used a DC/DC converter so it was a different load each time, and yet it worked.

I'll create a seperate discussion thread this evening.

The washers do not play an essential role as far as I see it at this moment of time.
I excluded them in my single module sims, reflected in reply #2524

You're right. I may have expressed myself too strong here.
I was aiming at maximum output, so was RomeroUK, explaining the importance of the right tuning criteria.
The buffer capitor before the DC/DC convertor is essential here as an low impedance buffer as well as energy buffer.
The buffer capacitor is the dominant load impedance, in my view.
But, if you want enough margins, you have to get the bias adjustments as perfect as possible.
Obviously, RomeroUK had enough margins.

Hi all,

I am here not to give you any info or directions regarding the Muller device, that is not going to be anymore but I am seeing a lot of people spending a lot of time and money thinking that just looking at my device is enough to make a 100% replication.
I hate to see people spending money on something they don't understand completely.

Most of the time is not what you see, is not in front of your eyes it is a bit more than that.

My advice to all of you is to stop working on the Muller device and just play with a simple rotor and 2 coils, one driving and one for collecting. When you will make that to speed under load or shorted then you can apply that to different even more simpler setups.

I know that most of you will say that the speed up will bring the rotor to the original speed where we don’t have the collector coil in place and there is no gain. Try and measure the speed before adding the collector coil then do the same when you shorted the coil. I think that is easy enough.

If you cannot get this effect then you will not be able to get to the next step and better stop before wasting any more time and money. My Muller device had a little bit from all of my discoveries during many years of building and testing and most of the time I failed in getting my goal but every time I have learned a bit more.

This arrangement is a complicated one and requires thousands of adjustments but it can be built in simpler ways.

Lately I have tried different toy size arrangements and I will build a total different type hopping that I am not going to upset anyone now.

I’ve got all the parts I have ordered before, thinking to get a bigger size Muller device and I will use them towards a different concept, nothing related to Muller idea.

Now again, I hope people will think many times before starting any project then decide what to do and please do not take my devices or ideas like an invitation to replicate, that is your decision, don’t blame me if you fail, we are all the same but still, not all can play football but we like to try and maybe we will learn.

Best Regards to all,
Romero

The thing I don't understand is that before you were very helpful in describing your muller device and said that all credits belong to bill muller and you don't wanted money but it belong to the public, you agreed with the info posted in the pdf and answered questions on how to build it. That is the reason people are trying to replicate your device. You also said that you were hoping someone would replicate it and you were very encouraging.

well done, first one that shows some progress.
who is next?

Now you say that the info is incorrect or at least something is missing? If you don't like people spending time and money why didn't you say so in the beginning?
