Muller Dynamo

Hi Hoppy,
you are right.

I just watched it carefully again.

Here:

at minute 10:05
he pulls off the battery powering the motor coils.

Then you see the voltmeter directly go to about 5.88 Volts.

As he has connected still the driver coils to the voltmeter via the freewheel
diodes 1N4007 now we can see, what at nearly full speed the driver coils
BackEMF puts out.

At about minute 10:34 you can see the voltmeter again having only about 2.20 Volts and then going down
the next seconds to 1.72 and 1.45 until the RPM stops.

So we know now, that the recovery diode is(are) not the 2 freewheel diodes 1N4007
as they are producing to low voltage....

Okay, now we know, that the LED of the DC2DC converter can really be on this long.
Okay the 5.3 Wattsseconds of the stored energy inside the 47.000 uF cap will
be used up in about 3 seconds, but then the DC2DC converter will not produce any more voltage,
and then the 2 x 1N4007 freewheel diodes of the 2 drivercoil pairs will generate at least still a few
seconds longer the voltage for the LED inside the DC2DC converter.
As Hoppy has told us, that the LED also lights up,
when you put 3 Volts across the output from outside then the still
running rotor will induce the voltage for the LED inside the DC2DC converter and
will
feed it from the 2 x 1N4007 freewheel diodes to the output of the DC2DC converter.

I guess this is the only logical explanation, if there is no  hidden power source.

Regards, Stefan.

Plengo,
I agree with your observation short of the trigger coil.  please explain the need of the trigger coil.  I feel that the coil without the magnet is the only place that a magnet can positively rest due to the repelling of the bias magnets.  It is attracted to the ferrite, and on the other side it has no place to go but centered.  I have thought that maybe the generator coils feed themselves and aid in the repulsion with the reverse emf induced in the coil. Sort of like a flyback or magneto action.

It's not just a replication.
The company is run by Muller's daughter and supposed to be an advancement of Muller's design. This has been pointed out already in this thread.

someone was asking earlier today about what happened to the guy Rod who had a simpler (1 stator plate), DC motor driven device - not heard of since around his 2008/9 build

iirc he called his 'company' NeoGen

i notice that the new Muller gen company is also called NeoGen

was there a buy out perhaps?

or did poor old Rod (no job, heavy mortgage) get an 'unscheduled  visit from the Muller company lawyer to stop him selling his plans for a 'Muller Generator'?

does this scenario sound familiar?

maybe the Muller company heard, like we all did here, that Romero had been approached with an offer

the lawyers can't object to someone making a copy for 'research purposes' - but they won't sit around for long if they think that the design of a device, which has clearly been stated as based on the 'Muller Generator', is about to be sold to a company (who will obviously want to get a return for their investment)

just an idea

I would think that all the biasing magnets were positioned so that they would FORCe the rotor to be centered on the trigger coil. This would be the most optimal way of putting the whole magnetic closed flux balanced path to be out of balance for the least amount of input energy and causing a 1/2 rotation so the next trigger coil can repeat the process.

This is why i also think that the tri-gate part plays a role.

Not trying to be dense here Fausto.  But what is it triggering?  Not the driver circuit right?  they have Halls.
