Muller generator replication by Romerouk

[hello_all]

how about 2 brushless outrunner with pulleys to run a flyback with some weight for inertia/momentum.. and low rpm on flyback due to gears/pulleys .. and then back to the second outrunner using gears/pulleys acting as a generator ... with different gear to make it run faster on the generator side.. in that case there will be loss but flyback can make it back..

Hi

I mean did you use your forest for the trees method or not? As I recall your magnet diamaters were about 10mm and the core was 20x20mm, what about the spacing between the core and the magnet, also the wire gauge and the number of turns, and also your coil length?

Thanks!

I just wanted to mention this, since you are talking about trees/forest, there are some rules that need to be respected for you to be able to do so....

so just FYI:


Seeing the forest through the trees

Imagine you are walking through a forest. All around you are trees of different species, age, size and height. It looks pretty random, right? Wrong.

In research funded by the National Science Foundation, Brian Enquist of the department of ecology and evolutionary biology at the University of Arizona and his team have discovered a secret in the trees: Hidden among and within the architecture of the branches are fundamental rules that link the size, shape, age and in fact everything about a single tree to all the trees in a forest.

Wow, Rod, incredible ! What a huge saving in input watts and a good increase in RPM. And all the drive cicuitry can be dispensed with too !

It makes me wonder why Romero didn't just stick with the motor as driver ?

Do you have a link to the motor you bought please ?


Cheers,

Gary.

I don't have a link as I brought the motor year or so a go. it's 1038 KV type.
I would suggest something a bit lower, slower it obvious that 5000 RPM would be enough.

Be careful about those flying magnets man. We don't want anything happen to MVPs. lol I know people think Tesla is cool for running his motors so fast it fly apart... but I just think he turn it on and find a place for cover. lol

I just burnt out the motor. I hate the smell of burring enameled wire.

I was tying to get to 9000 RPM got to 7900 and smoke from the coils. I was trying an 18 volt battery I think the current got as hi as 7 to 8 amps I was not looking at the meter just unplugging every think. I have some much better motors in one of my models that are faster and not so small with large current demands. these motors come in a verity of loads and power.

The funny thing is I have been drinking that Redox ASEA that I brought from Aaron. that's stuff works so good I usually would have been in bed by now to tired to think.
I am awake think of ways to burn out motors
I am not joking that stuff helps you concentrate a lot better, I am just not so tired as i would normally be.

with the Mu metal I have tested both. with the magnets and with out the magnets. works just as well with out the magnets just the voltage is lower.

the Mu core is 14mm x 14 mm and the magnets are 10mm and the space is as close as you can get without the magnets ether side of the core and 5 mm gap with the magnets. coils specs are 5.6 mH gauge 18AWG 1.1mm length I think around 24 meters at 280 turns.

out runner

@ Toranarod
I remember when Romero posted that info on the Turnigy motor. Not too many people were interested. Everyone just wanted to replicate his Muller.

Yes you missed something, Romero had 2 wires going down the table. I asked him several times about it but no answer. You can read all about it on his forum at UnderService.Org - Index

Regards

I have not noticed the wires, maybe ... maybe Romero was hoaxing, but was Muller hoaxing too?
I believe that there are some serious anomalies, that need to be resolved.

[elias]

MU Metal Core or Iron core ?

The MU metal is very defined set of specs.
The data you are requesting?
All Specification.? I have already posted some of this information.
What are the specs you are looking for specifically.

Have you ever used an out runner Motor. They are a pulse motor but have no hall sensor or reed switch. they sink right up to the pulse frequency. I am currently installing one in the top of my Muller motor as a drive motor. they get up to 7000 RPM. they use a processor based speed controller. Do any of you remember RomeroUK saying theses OUT RUNNERs are almost OU straight out the box? He said He re wired ONE Who Remembers that?

It may be possible that the speed is being control by the L and C of the circuit itself. Anyone notice the first vid he use only 2 pins on the coils while the assembly vid shows 3 pins being connected. On the 2nd vid with the battery, it stop when the battery fall off while the first vid the capacitor didn't discharge when he charge up. So the set up are different. I've come up with my own schematics for the two vids but I don't see how it works for the first vid unless the diodes can't handle that speed.

PS- the little motor looks tough lol

@stevie1001

The speedup-under-load effect discussed at :

http://www.totallyamped.net/adams/index.html

had a core diameter which equalled the magnet diameter.

That article discusses the Adams device.

But Adams stated that the face area of the magnet must be twice the face area of the core, so, in the case of a circular core and a circular magnet, the magnet face must be twice the diameter of the core face.

I'm not sure what Muller's ratio was, but i assume you are already aware of the details of Romero's Muller replication in this handy thread, the first post of Romero's in this thread has a link to a PDF with all of the necessary details :

Muller Dynamo

Hope this helps,

Gary.

good looking build The Muller motor is a big job to replicate we appreciate the effort it takes to make one. pleases post-more PICs

I will post more pics, when it will add some to the process....

I do have a question about the cores for the coils.
Its about the diameter to use.
The whole idea is to use the strongest magnets on the rotor, is it?
The purpose of the magnets is to saturate the coils with its mag field.
There must be a some kind of balance in that.
Bigger magnet makes it possible to saturate a bigger core/coil?
Bigger magnets make it possible to run higher speeds and still saturate coils?
Reversed thinking is that smaller magnets = smaller coils and lower speeds.

I think that i will stick to the theory that the core diameter must be at least equal to the core diameter. That way you catch all field lines of the magnet at least for a moment in time.
Or do you have a good ideas on this?
All theory's are welcome on this.....
