cool video i just replicated a circuit kinda of like what remero has but i just used a trigger coil with kind of a bedini set up. it works good speeds right back up when i find that right spot.your video amazed me though cause u had no circuit when u were shorting out the small red coil. this is the first day ive looked into this and i think its awsome. so one of u guys said somethin about the right capacitor being needed to catch half wave stuff. how would u pick what size a capcitor to use. would u kind of be looking for resonance or something?

hi Kehyo

That 2nd quote is very good -

I have question about it - he says to put capacitor 220uf-470uf 16V "from plus to the minus" and this capacitor will self-charge and discharge, giving the rotor some acceleration.


When he says "plus to minus" this to me, means its a "series capacitor" but maybe its not and its paralell across the coil or the mosfet?

Also I assume this capacitor is a DC type (polarized) but maybe for some reaons it is AC type  - it does show an AC type in the romero drive circuit drawing....

So is the 100uf cap in the Romero drive circuit drawing doing what he describes here?

And could you say that 100uf capacitor is hooked "plus to minus" or is this quote about a different circuit than romero's motor/drive coil circuit with the 100uf cap in it?

Hi konehead

The circuit is exactly the same as in the picture in my previous post. It is the same as the original driving circuit, I just removed the battery.
The capacitor is a DC electrolytic type hence + and - in the quote from Romero (referring to the battery terminals). The cap value must be selected to get several volts, around 5 to 15V maybe, just from the magnet attraction to the core so that the hall sensor works correctly and the PNP transistor opens.
So 100uf cap from the pic is the one to be experimentally selected depending on your setup and the RPM.

I also think that in his case he was using generator coils in this fashion as to pulse-charge the big cap.. seems logical and simple.

Hi Marius,

i think coil number one works best because :

1. The coil's width is roughly the same as it's height, square cross-section is best for power generation.
2. The wire is fairly thick (0.5 mm ?), so good for current.


All the best,

DC.

Hi Mairusivic

The video of the speed up from the aircores I havent seen yet - thanks for reposting this it is great to watch..

a few questions:

How many magnets in the rotor of that?

Are the magnets arranged N-S or all-N??

It is very interesting the way it doesnt work unless the motor-circuit spins the rotor clockwise
and at same time if you use the gernator-coil pulse circuit as motor-circuit,
it would be spinning the rotor counter-clockwise - and this relation in spin directions if both circuits happened to be used as motor coiol circuit is how it must be to get the speed up with the aircores. (thats how I understand it in  what you said in video)

Did you just swtich the polarity of the motor coil circuit to reverse direction??
and same for the gernator coil circuit "if" it was to work as motor coill circuit?

Or to change the rotation direciton, did you actually adjsut the timing itself??

If you change the polarity of the motor coil is all you did, with no timing-adjsutment to reverse direction;
then that means alot as to why it works as it does - since lets say the motor coil is attractive-pulse.....then the genrator coil circuit "if" working as motor coil circuit in the mode where it gets speed up - would be in "repulsive" mode of the coil to the rotor magnet...

In repulsive-mode to motor coils, and with aircores, having the magnet directly acrss the coil lined up "square" to it, is the most speed and power with least draw for the pulse-timing to be at...but for attracive pulse with aircores, having the rotor magnet OFFSET with center of rotor magnet near edge of coil gives the best speed and power and least draw so ther eis some time to pull the rotor magnet to the coil......

so knowing this, you could estimate the timing of that generator coil circuit pulsed into load that gives the speed up - in relation to the timing of the motor coil circuit......

(this means the time to pulse the gernator coil circuit is when a rotor magnet is directly across the coil with no offset at all...this makes sense, since that is when the coil could b pulsed "either way" and the rotor magnet wouldnt care which way to move if is perfectly squared up...so no lenz since lenz doesnt know which way to lug it)

In the mystery-5W coil, that works better than the others - is that and aircore or does it have a core when you test it?
Is that 5W in a "pulsed test" into a load, or is is a "lump resistive load" across it??

this  is my new vid http://www.youtube.com/watch?v=pxSe5yg0eW0

OK thanks for the explanation its very interesting and makes lots of sense.

That 100uf capacitor - in "regular" motor coil circuit, why have one of these?...maybe a much smaller one to smooth the DC or somethign but 100uf is fairly large capacitor so that is somethign interesting right there -

and then that single diode is there too, so it collects "half" the sinewave of the magnet-sweep past the coil through that single diode and plops it into that 100uf cap....just as a generator coil would do with single diode into cap...

then when mosfet turns on to pulse the coil with some juice, it takes the power it needs if from that 100uf cap.

ITs totally possible to string all "odd number" of  coils together (like romero does) and pulse this whole string of coils against a rotor of even-number of magnets - I have done this a lot actually - and you will have a decent motor running like this....

so your theory seems to be then;  that romero pulses his whole string of gernator coils at once from that  "2nd" halleffect-transistor coil circuit....it only collects from half of the sinewave too - via that single diode - and the other half of sinewave becaomes a free-push too, since it has those "regauaging/backing" magnets behind the cores....

so there is "no lenz" since the gernator coils are busy getting pulsed in a motor-mode on both sides of sinewave that the magnet sweeping past the coil creates (one side pulsed in motor-mode from cap and mosfet,other side from "pulsed" from backing magnet)

the only time has to do any work that could possibly create a slow-down  is the filling of that 100uf DC cap and that is fairly easy if  you find good size cap that fills up non-reflective and also has enough oomph at discharge to move the magnet (100uf)....

this also backs up Hector's theory that is "all"  from the "reverse diode" in the motor coil circuit, the looping result.....


Hi all,

Thanks for the good explanation Dougk!

I beleive that the small magnets on the side of the rotor is placed in line with the big magnets, so that every time the big magnets are passing the generator coils at the same time the small magnets triggering the mosfets to short the coil, thus lenzless and a speed up effect pushing the rotor away from the coils, plus more voltage from the generator output!!!  clever! has anyone tried this? or can confirm if this is really the secret of romero's looping?

Hi Chal
 
in that schematic drawing it shows the cap to be an AC type, as it is drawn wiht two striaght lines and DC type has curved line under straight line...But Marisuivic says its a DC type he used in his video (Marisuvics)....
 
I'm not sure where to look for the "yellow thing" you noticed that might be an AC cap in Romero's video and which video to look at ... but like I mentioned, he does have an AC cap in his schematic, not a DC one.
 
An AC cap "in series" will cut lenz law lugging of rotor down to nothing, but it will also make the large DC cap (connects to load DC cap)  fill very very slow too so you have to find right uf value that cuts down the lenz lugging somewhat but still lets the DC cap fill fairly quick.
 
Ron P did a whole bunch of tests a few months ago here, and he found that for what he was testing out, there was a very particular UF value that worked way better than the rest...so this is something that will need to be tuned/expereimented with for whatever is happening....
 
Basically you hook up the AC cap with one lead on one of the coil leads, and other lead to one of the AC legs of FWBR like that;
 
or if single diode is being used to rectify coil into DC cap, then the AC cap goes between a coil-lead and that diode...
 
you can put the AC cap on one lead of the coil all on "its own" too if you want to do it like that, so that the other lead of the coil goes to the diode
 
also you can use two AC caps in series also, and have each lead of the coil have an AC cap on it - this makes things look better on scope I remember for coil shorting but doesnt seem to realy help performance that much ("performance" being how fast a cap fills up)
 - but then again that test was peak coil-shorting coils, and for just taking power out "straight" from coil into cap, then maybe two in-series AC caps, one on each coil-lead would be better than just one it would be simple to try all three ways...
