Hi Romero

Congratulations on a fantastic build and project. 

Question.  What type of bearings did you use on you rotor?
I switched to high speed ceramic bearings on a pulse motor project a while back and gained over a 50% improvement in speed of my rotor.   Ceramic bearings also are not subject to magnetic effects.

Maybe by switching to better bearings you could get more output?

romerouk,

Nice work.  Thank you for sharing.

Stop risking a floor crash, keep it on a table!  Some will simply say that you could have thin wire routed along with your cotton string, (just out of focus of your camera,) powering your device externally.  What have we gained?

I agree with you: get more successful-replications running.

I agree with EMdevices: document the details and try to discover the fundamentals.

We would appreciate some more graphic details, maybe arrows and lines on top of actual photo images, showing these timing adjustment ranges that you wrote of earlier.  Please include some 'if-then' situations from your experience.

Stop and review some of your replies here and elaborate upon those those not yet covered in your original document.  The more detail that you provide in one document, the better chance you have of achieving your goal of sharing the stage.

Thanks again, man!

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.

If i may speak is BEST everyone to refrain from theories and old unproved concepts and focus on what Romero has ended up with.
First replicate, with all the meaning of the word i.e. not major changes (anyway, every one likes replicas), and then once successfully done, investigate yourself.

....

@bolt,

regarding RV it maybe work at extremely high electric to mechanic energy conversion in comparison to pulsed motors etc but the effect Romero shows that with load application (i.e. bulb and pulse motor) not affecting even slightly the device is outstanding at least and cannot be seen anywhere! (especially if there is not any considerable cogging torque present)

This is the discovered secret IMO thanks to Romero's experimenting skill and will to share.

I think you completely missed the point of what i was saying.  First it is not the replication that is important it is understanding the method and using Re-gauging on the back end of the coils to null out the lugging. This is a magnacoaster method and something some of us have discussed for a long time.

The drive of the rotor is not important as the pulse motor is only used to provide rotation. Any method of rotation can be used so long as its very efficient.  Already you will see no two devices will be the same as everyone will use the materials they have available to them. The magnets will be different strengths, the cores wound different, different core materials, the number of coils and magnets are probably going to be different BUT they all have a good chance of working if the re-gauging back end magnet is carefully selected to null the BEMF.

And Indeed Romero has suggested others try bigger coils and rotors to get more power. Alike the Joule Thief no two are the same yet most of them work!

For using 3 phase RV provides cheap method of construction with professional bearing and platform to mount a rotor. The perspex doesn’t come cheap either. A3 sheets of the stuff 12mm thick cost a small fortune!! RV provides an extremely efficient drive motor which can spin a very large rotor down to a few watts.

Now bolt the genhead stator and rotor direct to the motor shaft and you got your muller without using pulse drive and ALL the coils then become generator coils.

Not trying to jump ahead too fast, but does anyone see the possibility of a non-rotational version?

Bolt, are you saying the key is that the generator coils experience no or little cemf?

Why do you stress so much about the no battery's inside??

Did you ever turn a generator by hand to lite up a 12 volt 20 Watt bulb?
It needs alot of kinetic energy to do that.

Which is why i can tell your device is a fraud.
That rotor is spinning way too slow to burn that lightbulb but it seems i am the only one that sees that.

Maybe that is because I actually used a lot of hand driven generators...whilst the rest of the members never did since they can just plug things in.

When I was a young telco technician in the uniselector to crossbar era, cranking at the handle of a 50 volt telephony gen to substitute as the battery was indeed a very difficult task when there was a significant load on it.

I did it regularly during pre-commission of installations for small businesses to verify each telephone working wire path integrity before connecting it to the switchboard systems.

But changes in modern conventional hand-gens make the task a little more efficient and a little less arduous.

However, the counter emf always opposes the effort in closed systems, thus requiring continued extra energy input to facilitate not just the transfer of mechanical to electrical energy, but also to maintain the rotation that is required to produce it against the natural breaking of the counter emf that arises for doing so.

Open Magnetic Systems seem to obey a unique set of energy transfer rules. My personal experimental observation on these systems in recent years points the finger towards the manipulation of the transition and block walls of interactive magnetic solids.

There is a very fine crossover point with magnet distance, where the decreasing strength of the field due to distance from the magnet changes from a root x distance squared to a decrease of root x distance cubed.

In this very fine area of crossover in the magnet to core interface distance, maximum flux change per unit of energy spent can occur. In other words, the right distance, or tuning of the gap makes a great difference to efficiency.

OU ? -  well, I dunno, But those who have the ability (and means) to replicate will either verify it for themselves or not. I'll just see what happens next, I think, since I have the ability but not the means.
