Confirming the Delayed Lenz Effect

[CRANKYpants]

YA BABY!
WAY TO GO DC.

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

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 :

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 :

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 :

The results of that test are here :

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 :

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 :

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.

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! 

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.

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 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.
