Hi All,
I just compiled Version 1.1 of the PDF file describing the RomeroUK selfrunning device
in detail.

Enjoy !

Regards, Stefan.

Stefan,

There seems to be a problem here.

Thanks Stefan!  That will help a lot of people.  I know this thing about the Litz wire keeps coming up so I really really hate to ask this.  Not being in the U.K. I would not want to buy from Romero's source so I was looking at other places BUT I keep seeing that diagram someone uploaded and it's in your PDF compilation of the 7 x 0.125 mm wire.  Here is the problem and to me it looks like a typo.  Seven 0.125 mm wires in a bundle as shown in that diagram would have an overall diameter of 0.375 mm but the diagram shows an overall of 0.875 mm.  A 3 and 8 look a lot alike at a glance so I'm fairly sure that what you have there as 0.875 mm should actually be 0.375 mm overall diameter which for U.S. people is about 27 or 26 guage wire.  Otherwise we are looking at about 19 or 20 guage wire which is a big difference in size.  I'm fairly sure at this point it should be the 0.375mm or about 26 guage for U.S. builders.

duff,  do you have cookies on and do you choose 'login forever'?  If not try that.  I just downloaded it no problems.

Just a quick comment on using an external high efficiency motor vs the two drive coils.

While the external motor idea sounds great and it may actually work, at this point we do not know if the two drive coils also contribute to the overall system power generating performance. It is a fully dynamic system with fixed strength fields (magnets), rising and collapsing induced fields (power generation coils), and impulse externally driven fields (drive coils) all those are happening at high speed and with close proximity to each other, most likely superimposing and effecting each other.

I’ll echo what many have already written: a true replica should be as close if not identical to the original. Establish a working base line, and work from there. Because if it doesn’t work, how would you know if it is the principle or the modification/deviation from the original setup shown by romerouk?
As romerouk noted many times, small things seem to make a huge difference.

@ romerouk and all involved, great work
Thanks for taking the time to post and answer so many questions.
Mike

Below is a picture with the scope connected at the AC point before bridge.

Answer: I run out of neo magnets. I am sure that more magnets will increase the output. I have ordered more togheter with the magnets for the new setup.

@romerouk:

I have read through all the new posts before posting.

Thanks for answering my questions by taking closeup pictures and giving reasons why the setup is in current shape. Meanwhile, I also realize that your current build left a lot room for improvement, clearly the potential is amazing and the condition of obtaining selfrunning does not seem to be too demanding, therefore successful replication should be quite possible given the skillfulness of the people here.

Yes, I agree with you that no more demo video need be made to convince those suspicious, because that is simply impossible! Just wait until replications come out. We can all keep doubting, but no more demo helps any more. Replication is the only way to drive out all suspicions. Therefore I think it is wise to concentrate on replications, but no more persuations!

At this moment, I am still struggling with the timing. I am not sure when the hall sensor activates the driving coil yet -- even with the help of your closeup pictures. Neomagnets are quite strong, it could be the case that the hall senser is activated well before it is above the big neomagnet on the rotor. Another possibility is that the drive coil is activated when it is approaching the neomagnet next to the one that is activating the hall sensor.

With scope shots we might resolve this issue for good. I wonder if you have a scope with two pairs of probes. Then one pair of probes is fixed to the generator coil immediately before or after the driving coil, the other pair of probes is fixed to measure the voltage drop across the driving coils. This way we should be able to see for sure when the driving coil is activated in relation to its relative position to the neomagnet on the rotor. If possible, please do this for both driving coils.

Thanks a lot!

lanenal

Edit: We need a simultaneous measurement of the voltage on the generator coils immediately before or after the driving coil to determine the relatvie position.

I am about to get another rotor manufactured. as you know the cost is in the tooling so I pay for one is expensive.
so i can have more than one made. If any body is interested please say as I will just get them to do a few more. you will get them for the cost of what they cost me. and  postage.

this is for a rotor the dimensions are on the drawing

Several of our guru's have mentioned using Schottky diodes.  I think that's an excellent idea and I can't see how it would effect anything in a bad way (99% sure).  Can anyone recommend a particular number that would work well in this replication?  Most are cheap enough that even using all Schottky's to make FWBR's should not add that much to the cost but what model number might be best here?

this why I am put out expressions of interest the company is going to ring me today will a quote.
I know the bearing center may be different for others but its based on a very ready available old hard drive size. trying to make it possible for the most basic novice to have a go.  cheaper the better. the Drive is WD caviar. this is the most common.

looks like the ferrite cores are going to be 10mm they are the cheaps and easiest to get.

I use them on the bridge in my Adams motor the voltage drop is very low. as a full bridge hard to get.

Hi folks, so does anyone foresee an issue with using those large ferrite beads i posted a pic of at top of page, thanks. Right now I'm preparing the steel bolt versions, though I doubt it will work well, that's why I'm thinking about the ferrite beads, at $3.15 for 9 is a deal.

Yes I know it's not common in FWBR but very easy to make the FWBR from 4 Schottky's as I know you know that.  I just would like to know what model number might be best since I'm thinking of ordering some.

Thanks Stefan.

I wonder if overunity can also backup some of the important videos as well. Youtube might find reasons to close those. Also, in some countries (like mine), youtube is masked and can't be visited.

Just guessing here but it seems they would not have the same flux pattern and probably not as strong as a solid ferrite rod.
