Hi everyone. I always believed in Muller  odd / even type design.  I include my solution of this type of generator. I think it could be more efficient.
It is based on a monolithic toroid with columns type core made from magnetite/powdered iron mix with resin. Precise timing with micro controller could make it run better as well. The idea is to incorporate coil shortening at TDC of a pole vs core column only to turn a 'drag' into a 'repelling pulse'...

There has been a lot of talk about the DC to DC converter.
What was its main function. Stepping up the voltage, isolation, both.
Where in this thread is it discussed?   
I have a few in my supply box have tried them on other motors but the efficiency was in question what switching chip did you use

Just in case it wasn't clear in penno64's answer the main function was to loop the output to the input with isolation and regulation thus eliminating the battery and proving OVERUNITY :) :) :)

with most of the design its a pulse motor of a kind. the one thing i am very interested in is the use of the Litz wire. having seen the wire in old style CRT TVs
most of my life. I was always wondering what it may be like in a pulse motor setup. very cleaver use of this wire.
I have no doubt the hole design is relevant to its function but I would not leave out the coil configuration as a major part of its parameters.
having trouble getting the wire here in Aus. the main industrial supplier don't carry it.
 
How much wire did you buy as an average to build the motor. how much should i order?
cheers

Sorry to ask again, but this looks not clear to me: http://www.overunity.com/index.php?topic=3842.msg284616#msg284616

I thought you'd only need to use 4 diodes like this: http://static.electro-tech-online.com/imgcache/1674-4_diodes_bridge_rectifier.jpg , therfore I dont understand what this square shaped box in the middle is  ???

Very interesting stuff!!! This should be the device of the year!

I think with the contribution and information sharing here, it is quite possible to replicate. I read thru all the posts here, I have a few remaining questions:

1) are the driving coils as far apart from each other as possible? or are they arbitrarily chosen?

2) when the driving coil fires up, does it strengthen the magnetism in the ferrite core or rather weaken instead?

3) any advice on tuning? what are the tuning parameters (my guess is: gaps between the rotor and stator, and # of washers between the magnet and the stator)? what are the general guidelines? what are you looking for?


I also got this wild conjecture somehow, might be totally wrong -- might help my understanding: can you use odd # of magnets on the roter and even # of coils on each of the stator?

Also, it seems to me, this device differs from Adams Motor mainly in the auxillary magnets that are attached to the stators.

Thanks to RomeroUK who shares this with all mankind -- this technology should definitely change the future of mankind if it is easily replicable and broadly applied. Thanks to all who facilitate the replication and spreading of this technology~!

cheers, lanenal

The square shaped box symbolizes the 4 diodes you refer to in your second link.  You can clearly identify the AC inputs (~)  and DC outputs, just the diode symbols are not shown inside the box.  Clear?
It all shows that Romero used 4 more diodes, beside a full wave bridge, and the 4 diodes are connected parallel with the inside diodes.
This way a small decrease in forward voltage drop can be achieved for the 'compound' diode bridge so the power loss is decreased and mor power can reach the load.

The square is a bridge rectifier and diodes are making another rectifier in parallel.

@gauschor,

I think he first did use only the diode bridge. Then later on he added four 1N4007 to get two
diode bridges in parallel. He got more output that way. You can probably take both the bridge
and the 1N4007 away and use some fast Schottky diodes instead.

[Edit] Sorry, I did not see that there was posted answers to this already.

One great idea leads to another.
I have built a few Adams motors in my time But i must try this as a immediate response to this great discovery. It will be a few days while i get the materials together But I am keen to start Now so I thought I would test the 9 coils and 8 magnets ASAP so I am modifying one of my Adams motors. doing this now.

I wonder if just two bridge rectifiers doubled together would be the same?

This one is much easier to build. I tested it with very good results.

The 'helper magnet' is separated from the coil by the thickness of the acrylic (1cm).On the acrylic is glued  a 1mm/20mm washer then the magnet on top.
I am driving in attraction mode. I have started the project in repulsion then tried attraction. I get much better torque in attraction.

Does the attraction mode work this way: the driving coil is switched on when the rotor magnet is approaching and then the driving coil is switched off at the TDC?

@All,

My old Muller motor/dynamo has been collecting dust for 8 years now.

Now I have cleaned the motor and is wiring up the coils. I have
eight 32mm dia x 20mm Neo magnets in the rotor arranged NSNSNSNS.
(Can't make all the magnets the same side out. The magnets are
glued to the rotor.) I have 7 coils pairs. All coils are air core, so
no clogging. I use one coil pair as motor and 6 coil pairs as
dynamo. I have 30000uF 25 Volt capacitors. (Three 10000uF in parallel.)
My Muller is made of Bakelite (paper phenol).
