SORRY I DIDN'T MEAN THE ROTOR - WHICH CAN BE ANYTHING INCLUDING LEXAN BUT NOT PLEXIGLASS AS GOTOLUC FOUND OUT WHEN HE BLEW UP HIS BROTHERS GARAGE!  :P

I MEANT THAT CORE/BOLT MOUNT WHICH IS SECURED TO THE WOOD - IS THAT ALUMINUM?

IF SO IT IS CREATING LENZ DRAG ON NO LOAD JUST BY SITTING THERE.
IF IT WERE "SOFT" STEEEL IT WOULD ATTRACT ROTOR FLUX AND PERFORM SLIGHTLY BETTER. THAT IS ALL I MEANT.

Dear Thane,

Indeed, the core/bolt mount is made of aluminum... And I agree that by just sitting there it will decrease the performance of the generator coil. But in my case it has to be made from a solid/stiff material, because otherwise it will start vibrating when the rotor magnets are passing by.

But you are right maybe it is better to replace it by a soft steel core mount, instead of using aluminum...

With Kind Regards,

Overunityguide

DEAR OVERUNITYGUIDE,

IF YOU WANT TO AVOID THE "RATH" OF OVERUNITY FORUM ARMCHAIR CRITICS THEN YOU HAVE TO SO SEVERAL THINGS WHICH INCLUDE:

1) BALANCING COGGING TORQUE SO IT EQUALS ZERO,
2) USING CORES THAT HAVE NO HYSTERISIS LOSSES OR CORE LOSSES,
3) USING A PRIME MOVER AND FREQUENCY CONTROLLER THAT ARE 100% EFFICIENT

IF YOU CAN'T DO ALL THESE THINGS INSTANTLY THEN YOU WILL BE SHUNNED AND PERHAPS EVEN CRUCIFIED ON THE ALTAR OF PUBLIC HUMILIATION.

OR YOU COULD SIMPLY SAY WHATEVER ... AND MOUNT YOUR MILTIPLE COILS ON GOOD TOROID MATERIAL IN THE FUTURE TO KEEP THE INITIAL LOSSES DOWN.

Hello you Guys,

Today I have made a new Video about the Thane C Heins, Regenerative Acceleration Effect. This time there were no moving parts involved. This time I was able to show the same effect inside a transformer...

Please see my new video about the regenerative generator effect also taking place in a transformer:

Good experiment idea and video demonstration Overunityguide

I will try it using my signal generator output on a special toroid core that has an extremely high permeability. As it is I have a winding on it of .8mm wire and it measures 7.5 Henrys and an unbelievably low 4.4 Ohms DC resistance.

I'll have to dig out my signal generator and also do a primary winding on top of the 7.5 Henry winding.

I'll post a video demo in some days

Thanks for sharing

Luc

Hey Luc

Wow.  Thats kind of unheard of. What kind of core?

Hi Mags,

I also have a hard time believing the Inductance value but it's what my Inductance meter reads.

The the Toroid core was given to me by user Peterae  and I think it's this model of FERROXCUBE: http://uk.farnell.com/jsp/search/productdetail.jsp?SKU=3057010

Let me know what you think

Cheap too.  What do you have for wire/turns?

I did not count the turns. I made this coil over a year ago. Anyways, don't know what it's going to do until I try it.

I'll have to dig some stuff out to test it so it's going to take some days.

Keep a lookout ;)

Just thinking about it, this may be able to breath some life into a microwave transformer. Just need to find the freq of operation.  ;]

Hello you All,

After a couple of questions about doing a video about scope shots and power factor measurements on my Regenerative Acceleration Generator effect Transformer, here you can find my follow up video:

Mags

The AL value for the TX36/23/15 3E5 type toroidal core is 11400nH/N2 

This gives about 811 turns for the 7.5 Henry measured inductance
(formula is N=(L/AL)1/2

811 turns sound very much and probably filled up almost all the inner diameter or the toroid core. The 4.4 Ohm DC resistance for the 0.8mm (I considered 0.812mm for AWG 20 which has 33.31 Ohm resistance for 1000m length) copper wire gives about a wire length of 132 meter. Is this more or less ok, Luc?

@Magluvin,
It depends on what Inductance / Impedance your secondary coil of this microwave transformer has... For sure it has to be high... But with my setup I am limited to 950 Hz, because that is the upper limit of my frequency drive controller.

But when you can go higher than 950 Hz, than your inductance / impedance of your secondary can be slightly lower, but still it needs to be way higher than the primary coil. But the laminations for higher frequencies needs to be also be thinner.

Mags, do you know what a normal inductance value would be for the secondary coil of a microwave transformer?

...

...


It must be in the several Henry range.  A google search brought this:
primary L=68.2mH 
HV secondary L=15.5H
(from this link: http://sci.tech-archive.net/Archive/sci.electronics.cad/2008-02/msg00082.html )

Maybe the laminations could work up to some hundred Hz for the older type transformers (nowadays there are ovens with switch-mode power supply to get the HV too).

Cheers,  Gyula

PS: just recall this pdf file member poynt99 uploaded that includes info on oven transformer, page 17:
Primary: R= 0.35 Ohms; L= 44.4mH
Secondary: R= 88 Ohms; L= 19.3H
(from this: http://www.overunity.com/index.php?action=downloads;sa=view;down=209 )

Hi Gyula,

I had to pickup my Digital Caliper from storage to re-check the diameter of the wire. It is actually 0.50 mm with enamel coating. The DC resistance is correct @ 4.4 Ohms so you should be able to figure out the wire length and approximate amount of turns.

Let me know if something does not look right.

Thanks for your time

Luc
