Nilrehob,

Another thing to keep in mind is how to actually connect a bifilar coil.
This can be done in a few different ways.
For maximum capacity one should use the 'tesla coil way'.
I described this elsewhere : http://www.overunity.com/index.php?topic=11009.75 , reply #88
You can see the estimated increase in capacitance is hugely dependant on the way a bifilar coil is actually 'wired', especially when there is a significant number of windings.

p.s. this is not meant as a pancake coil only. It is applicable for any wired coil.

Thats the way I've done my bifilars as well,
the only way I haven't done yet is a stack of pancake coils (bifilar or not).
The best performing coils that I have done so far is the NEATLY wound coil,
with this I mean each layer perfect without bumps and crossing.
But i will look into it again.
Thanks.

/Hob

I've upped a video of acceleration-under-load rather than just short-circuit.

The rotor speed rises by only a few Hz, and the milliamps only go down by a few but the effect is there and will be amplified with higher impedance coils.

Hi everyone,

here is an update on the Delayed Lenz effect in the MOT.

I did some test that give good results by using a Capacitor in Parallel on the Primary of the Transformer.

Please note at one point in the video I say the Primary of the Secondary. I meant to say Primary of the Transformer. This kind of thing happens when I'm doing many things at the same time (shooting video, explaining and thinking of the next thing to do for the test)

I attached the scope shots of the two different Frequencies used.

Green waveform is Current (Voltage across the 1 Ohm Resistor) and Yellow waveform is input Voltage.

First shot is the Transformer @ 2.45kHz no Load or Capacitor
Second shot is the Transformer @ 2.45kHz with Load and .39uf Capacitor in Parallel with Primary
Third shot is the Transformer @ 578Hz no load or Capacitor
Forth shot is the Transformer @ 578Hz with Load and 6.8uf Capacitor in Parallel with Primary

Please post your comments

THIS IS AWESOME LUC!

IS THE YELLOW SINE WAVE THE PRIMARY VOLTAGE?
BECAUSE IF IT IS THEN YOU ARE SHIFTING TO POWER FACTOR FROM POSITIVE TO NEGATIVE PRETTY MUCH AT WILL...

AT SOME POINT THE POWER FACTOR IS ZERO WHICH MEANS THE POWER TO THE PRIMATY IS ZERO.
IF THIS IS TRUE THEN YOUR EFFICIENCY IS INFINITE DUDE!

AT YOUR "LOW" CURRENT LEVELS THE POWER FACTOR IS 1 MEANING THE CURRENT AND VOLTAGE ARE BOTH IN PHASE.

BUT THEN IN THE VIDEO YOU SHOW THE POWER FACTOR GOING TO ZERO AND THEN NEGATIVE!

IF THE POWER FACTOR IS NEGATIVE YOUR TRANSFORMER IS POWERING THE LOAD BUT ALSO SENDING POWER TO THE GRID... DUDE!  :D

THIS HAS BEEN CONFIRMED BY COMPUTER SIMULATION AND ON THE ACTUAL OU BiTT (AT OTTAWA UNIVERSITY),

WHAT IS REALLY COOL IS HOW YOU CAN SHIFT IT LIKE THAT.

PLEASE CHECK TO SEE IF THE YELLOW SINE WAVE IS ACTUALLY CONNECTED TO THE PRIMARY WITH THE GREEN ACROSS A RESISTOR.

Thane, I was drawing the same conclusion at first glance, but.....
to be dead sure, we need the total primary current, while the primary current that Luc is showing is only the current that is going through the primary coil and not the current through the parallel capacitor, at least that is what I observe from it.
The current through the capacitor should be added as well.

So, Luc can you check whether you connected the parallel capacitor before or after the serial resistor?

HEY LUC,

YOU HAVE A RESONANT CIRCUIT THERE...  ;)
I STILL WONDER IF THIS (AND OVERUNITYGUIDE'S) TRANSFORMER DELAYED LENZ IS ACTUALLY A CORE HYSTERISIS DELAYED EFFECT OR A BIT OF BOTH?

Parallel LC circuit Resonance

Here a coil (L) and capacitor (C) are connected in parallel with an AC power supply. Let R be the internal resistance of the coil. When XL equals XC, the reactive branch currents are equal and opposite. Hence they cancel out each other to give minimum current in the main line. Since total current is minimum, in this state the total impedance is maximum.Resonant frequency given by:

Thanks for the video gotluc. :) I have a question though, did the circuit act differently if you shorted it vs using the led. The reason I ask is, don't led's act as diodes? This wouldn't be the same as a short circuit. Now back to watching the video..

Also, you keep saying current changes when it is the voltage isn't it?

MY GUESS IS THE SHUNT RESISTOR IS CONNECTED IN SERIES WITH THE TANK CIRCUIT EITHER WAY THOUGH - BEFORE OR AFTER THE CURRENT THROUGH THE SHUNT IS THE TOTAL CURRENT UNLESS MAXWELL'S EQUATIONS ARE WRONG...?

OH WAIT THEY ARE!  :-\

AT ANY RATE MY POINT IS THE CURRENT MAGNITUDE IS IRRELIVANT IF THE POWER FACTOR IS ZERO.

WHAT IS REALLY OF VALUE (TO ME AT LEAST) IS SHIFTING TO PHASE ANGLE AROUND WILLY NILLY LIKE THAT.

LUC, PERHAPS I OUGHT TO COME OVER AND CHECK IT OUT CAN YOU DOCK YOUR BOAT IN CANADA OR ARE THE MIB'S STILL AFTER YOU?

BTW A LED IS ESSENTIALLY A SHORT CIRCUIT AND LUC ESTABLISHES THIS IN HIS VID.

Folks,

Luc connected the tuning cap(s) directly in parallel with the primary coil and the series 1 Ohm is placed outside of this parallel circuit, it is not included in it. It means that the current is at its minimum value as is shown when there is resonance (current and voltage gets in phase) while inside a parallel LC circuit the reactive current is at its maximum when tuned to resonance.
The current we see in the video is at its minimum at resonance because the parallel circuit's resonant impedance increases to a maximum value, this is what establishes the minimal current then.

Regarding the LED as a load? it is a diode and gives a near shorting effect in every second half period of the AC wave whenever the LED senses a forward bias from the AC amplitude.

BUMP ME !

Sorry to overlap gotoluc's post (i have always admired your videos, in fact i think that was why i joined OU.com) but i just attached a load and got an accelerated rotor with less current draw.

Does that mean anything to anyone or am i overstating the importance of my little experiment ?

I don't have a scope (well, i have a poor maa's soundcard scope just for frequency measurements) so i can't comment on luc's results.

But i would greatly appreciate knowledgeable comments on my results.

BTW Thane, i am DeepCut66 who sent you a video today.

YA BABY!
WAY TO GO DC.

CAN YOU POST YOUR MOTOR CIRCUIT PLEASE?
ALSO YOU NEED TO SWITCH TO BI-FILAR WINDINGS.  8)

CHEERS

Progress of my experiments with the effect of acceleration-under-load, an effect discovered by Thane C Heins.

Thane's youtube channel is here :

http://www.youtube.com/user/ThaneCHeins

To test for the effect i first tried to get acceleration under short-circuit. This was using a typical pulse-motor, using the standard SSG circuit to power the bifilar drive coil which pulses the magnets and turns the rotor. The magnets on the rotor then induce power into the generator coil, which has a masonry-anchor-shield bolt as it's core.

The coils properties :

L = 15.3 mH
R = 8 Ohms

Here is a picture of that setup :

http://www.mediafire.com/?b5thxa448at0dz6

At each stage of the test, the input current and frequency of the rotor were noted when the gen coil was open.

The gen coil was then shorted and the input current and rotor frequency were noted again.

The results of that test are here :

http://www.mediafire.com/?p4mw890t8unwc75

I then performed the same test using a diametrically magnetised magnet as a rotor, the advantages of which are that magnets don't come flying off and higher frequencies are easily achieved.

Here is a picture of that setup :

http://www.mediafire.com/?9pj521hbmk0cm4e

The results of that test are here :

http://www.mediafire.com/?v0hlb9ellahmu50

I then wound a new coil :

L : 250 mH
R : 120 Ohms

I performed the same test on the new coil with the standard rotor setup (not the diametric), the results of which are here :

http://www.mediafire.com/?yx6rttz533a6x7n

I then wanted to see what happened when using an actual load rather than a short-circuit, with the new coil.

I tested for this using the diametric setup, as the magnet has more flux and much higher RPM's therefore better inductive power.

I attached a miniature light bulb as a load. The result was that the light shone brightly while the rotor sped up and the current draw went down.

The rotor only sped up by a few Hz and the input current dropped by only a few mA but the effect is there.

Here is a video of that test :

http://www.youtube.com/watch?v=iSSOI6Yep_U

Although i have only tested two coils so far, it seems that a higher impedance coil exhibits a stronger effect and can support a higher load.

The first coil would drag the rotor with only a 15 Ohm load, whereas the new coil accelerates the rotor with loads up to 620 Ohms, anything higher than that and rotor drag starts.

Peterae had me do some simple, fixed-RPM tests with the first coil, these were the results :


CASE 1 - Rotor with no gen coil.

V = 8 VDC
I = .290 A
P = 2.32 W

CASE 2 - Rotor with gen coil, unshorted.

V = 9.8 VDC
I = .365 A
P = 3.577 W

CASE 3 - Rotor with gen coil, shorted.

V = 9.1 VDC
I = .336 A
P = 3.0576

Obviously the core introduces drag, while the effect introduces acceleration.

I am hoping that, with a higher impedance coil, the net effect will be acceleration.

The next step is to wind a higher impedance coil and do load-testing to confirm that the higher impedance does amplify the effect and can support a higher load.

If that is confirmed, the next step is to wind multiple coils and do further load-testing.


Thanks for reading,

DC.

Oh god thanks Thane !

I've posted this on four forums with no effing reply ! (sorry, us brits like to swear when we're frustrated).

The drive circuitry for the coil that pushes the magnet is the standard SSG, the magnet spins, induces a voltage into the trigger wire which gets the transistor to pull power from the PSU which pushes the magnet around etc ...

I know literally nothing about electronics, i just learn what i need to know in order to build things but i assume that you know what the standard Bedini SSG circuit is. It's what Robert Adams referred to as an inductive driver.

Funny you should mention bifilar coils, because, the drive coil being bifilar, even when i spin that diametrically-magnetised magnet on it's own with no gen coil, for the first 50% of it's acceleration the current draw goes up, as you would expect as the frequency rises and more pulses are delivered, but for the last 50%, on it's way to maximum RPM, the current draw drops hugely, so even the drive coil is experiencing this effect.

As i said, i am an electronics noob, but from the little i understand, this is an amazing effect and it's the only one i've seen succesfully replicated.

I have some mild steel round bar on order so i can try the same effect on a simple transformer.

I'm confused as to why not a lot of people seem to be replicating this, with a diametric magnet it's not an expensive setup.

Add a load and get more RPM with less current draw !!! Please peeps give it a go !

Also, when you say bifilar, do you mean two seperate windings or one loop winding ?

Sorry but bifilar seems to have as many definitions as B/CEMF so i like to be clear (because i know nothing !).

All the best,

Gary.

Hi Thane,

sorry for the delay in reply. I went to work after I posted this and got back in late.

Yes correct... THE YELLOW SINE WAVE IS CONNECTED TO THE PRIMARY WITH THE GREEN ACROSS A 1 OHM RESISTOR.

Glad ;D you like it

Tomorrow I'm going to my storage to pickup some large AC Capacitors. Going to see how far down I can drop the Frequency. It would be nice if I can get it down to 60Hz.
