Hi Mariusivic

Hope I am not bugging you too much but will keep at it!
(ha)

Anyways I couldnt get a decent HV coil short event into caps to happen for YEARS since the only way I could get it to work in dramatic fashion was through a REED SWITCH - just like you are doing...

A transistor would not work at all - Solid State mosfet relays would not work at all...never tried an SCR but figured that was never going to work either (it wont) so was very discouraged and gave up on it and could only demonstrate it with a reed switch if anyone would want to see this "very interesting" way to take power out of coils....

Then Ismael Aviso told me two summers ago that I need to have very very low resistance swtiching - the coil short oscillations created that fill up the cap so fast is VERY SENSITIVE to any resistance and any regular transistor will have TOO MUCH resistance and solid state relays are even worse....

you need to have  high amperage swtiching, and have it it like .1 or .05 ohms resistance to the swtiching when OFF (open)....the coil-shorting voltage-blast occurs at the TURN OFF of the switching so if swtihc has too much resistanc it kills it and there is nothing happening - like you jsut got.

so, you need to use mosfets - they have very lowest off-resistance possible you can buy plus they dont mind being in paralell either, so you can paralell 4 or 5 mosfets now you should have really good low resistance and high amperage swtitching
You will also need HV mosfets too like 500V or so...anyways when you do that now you can really blast some power into caps - with Reed switches,, they do have that ultra-low resistance, and thats why they work so good, but the power you can put through them is not very much at all and they are very unreliable over any long term testing...
(that said a FCC engineer told me that the US governmetn has 400Amp rated reed switches but the public is not allowed to use them!)

So anyways thats what you need to do if you want a hall effect to to trigger switching to short coils at peaks...

use say 500V mosfets, get some 8 to 10A rated ones and put 4 or 5 in paralell...this will work great.......IRF740s will work for small coil power like you are doing now - say 4 of these in paralell they dont cost that much....remember to have a "pull-down" 10K resistor across the gate and source streching all the way across the entire string of paralell mosfets or they wont shut off properly...I like to also put a 10K resistor across each gate and source of each mosfet as well as one all the way acorss just to make sure it turns off very quick and reliable....

is that double-peak  in scope shot of what the reed switch itself looks like with scope leads across it?
And so reed switch is also across the coil too , shorting it?

Here is what I get with scope leads across a capacitor, this is 60hz sinewave on mullergenrator with huge neomagnets and big aircoils , this has  "too big" of pulsewidth to it, but it looks good for photo of scope-form of all the  oscillations created..not that first half of oscillations are high votlage, 2nd half has decayed into much lesser voltage...making the 2nd half be of HIGHER voltage is what Ismael does in his very advanced coil shorting stuff like his MEG - he shorts the PEAKS of the oscillations createed so power expands in votlage....( I cant do this yet but working on it)

Hi Marisuvic

once again sorry to keep bugging as usual you but looked at your scope shot again jsut now and have to say something more about it -

what you want is just one of the "coil-short voltage peaks" you see happening a bit to the left, so you catch the positive peak right at the peak and not a bit after it like is shown - this shouldnt lug rotor at all...

its that 2nd peak in scope that will lug rotor badly but that is nature of reed switches ("double hits" to them like hall effects that will trigger both n and s of a trigger magnet)

then also you see that smooth looking negative-peak "turnaround" point down there below zero line doing "nothing"

THAT is place you want the 2nd coil-short to happen...so two coil shorts per magnet-pass of coil.......

Today i tested the device with mutiple (3) coils.

In these tests the coils are not connected together, they are short-circuited individually.

All coils are bifilar-wound and individually serially-connected, here are their properties :

1.

L : 20 Henries +, more than my meter can read.
R : 406

2.

L : 20 +
R : 402

3.

L : 13.2
R : 390


Coils 1 and 2 were placed opposite each other, North and South of the rotor magnet, so-to-speak, and the third coil was placed in between them, at the East position.

Results of multi-coil tests :


No coils present.

hz : 502

ma : 452

1 coil present open circuit.

hz : 417
ma : 472

1 coil present short circuit.

hz : 505
ma : 445

2 coils present, both open circuit.

hz : 393
ma : 475

2 coils present, both short circuited.

hz : 514
ma : 438

3 coils present, open circuit.

hz : 388
ma : 474

3 coils present, all short-circuited

hz : 511
ma : 440


I think i understand why two coils outperformed three with my setup.

Because it is a single-magnet rotor, the two coils on opposite sides of the magnet are synchronised in the sense that they both experience the flux change at the same time, whereas the third coil, which is in the middle of the other two, experiences flux-change after the first coil and before the second of the other two coils, so the timing is wrong and possibly fights against the effect from the other two.

I confirmed this by moving the third coil closer to one of the others and performance goes up.

Also, coil three's inductance is 13 Henries vs 20+ Henries and that may contribute to the lack of additional performance benefits.

Obviously the single-magnet design has it's limitations, the physical space required for many coils isn't available and the timing problem, if i'm right about that.

Thane's idea is that, with multiple short-circuited coils, any loaded generator coils that are introduced to the system will have a minimum detrimental effect.

I did a small test with a high current coil in place with two acceleration coils and it accelerated the rotor under load, helping the effect while powering a small light bulb.

I'll be making a multi-magnet rotor now but in the meantime i'll experiment with getting power out of this device, time to order some more high-current wire ;+}


All the best,

DC.

Hi Chalamadad and Deepcut,

Chalamadad:
Try to stabilise your singing coils (with RomeroUK exact drive circuit) so the rotor is at over 2000 rpm and just do exactly what RomeroUK did with the generator coils. You should be surprised. If you know how to apply coil shorting, then do it also!

Deepcut:
Nice experiment! Now you should know that the phase between each generator coils is important too. The best generator you can build must have even/uneven (uneven/even) magnets/coils. So your experiment with only 1 coil showed 2 things : 1) with this coil open, there is more drag than without any 2) With this coil shorted, there is less drag
Then depending on how many magnets you have on your rotor, you'll see that the number of coils must be even (uneven magnets) or uneven (even magnets). This is Muller basic principle. The drive coil should be included with the total number of coils. Play with phase relationship too (angle between each coils) and you'll be better than Thane Heins because you'll know that there is no overunity there instead of posting disinfo like he does. At least Thane's Bitt is working so he is not total disinfo guy.

Once you have built the ¨perfect¨ setup, now you'll want OU so apply coil shorting and/or RomeroUK/(maybe Chalamadad) OU drive coils and you'll be pretty happy.

Good luck.

Thanks Alpha for the comments.

Everything i've done over the past month or so just confirms Thane's theory as to how his devices work.

The BiTT is just a logical extension of the same principle.

I'm moving away from my old setup :

It's a single, diametrically-magnetised magnet.

Now to go Muller Style !
