Tragic accident with ball magnet EMDR motor-generator
« on: June 22, 2013, 09:08:34 PM »
Hello All,

the people from the VisionBlue Energy Team have built a very interesting device lately,
and called it the ball magnet EMDR.


  Here are a few videos about this:

It's kind of a Bedini-circuit where multiple coils placed over a Plexiglas tube
hold a ball neodymium magnet in place hovering on the magnetic fields and it is driven by the Bedini circuit to get into rotation.

The speeds you can get this way are very exotic and as the RPM increases this device
has huge power output capabilities with only low input power !

Some experimentors claims, that it is has a huge OverUnity factor !


Then there is a third  Coil, the generator coil, where you can pull off the output power.

I'm attaching below as Appendix 2 circuit diagrams.

It all started  with the Ricardo charger,
this is the first Youtube video linked above.


Unfortunately, there was a serious accident  on the evening of 20  June.

The Experimentor R. was experimenting with his about 1 inch thick diameter neodymium ball  magnet EMDR .

Suddenly when he reached very high rotation speeds, the ball magnet exploded, probably due to
centrifugal forces and several of the neodym parts have penetrated and ripped through his right hand !!


So please be very careful with rapidly rotating sphere magnets!


If there are high centrifugal forces at play the ball magnets can fall apart and
then the shattered parts fly off like bullets!

But he had probably tried too extreme speeds so far stated from his friends,
beyond the 100.000 revolutions per minute range !

Then, if the ball magnet inside already had a small fracture or an had internal crack due to falling to the ground once ,
then it may be due to the extreme centrifugal forces that such a bad accident can happen...  !

These ball magnets are also only produced by pressing together the neodym powder, so they will not withstand too much
centrifugal forces !


R.  was  already operated 2 times in hospital !

He was luckky to get nothing into his face or the head thank God! , but parts of the magnet stuck 2 cm into the wall of his room !

It was just about 1 inch diameter large neodymium ball magnet , which was torn apart by the centrifugal forces
at these high rotation speeds !

 

Here are some hints and safety considerations of the VisionBlue Energy Team:

Ball - EMDR - Precautions and Tips

To our crafters and friends of the free energy scene

Yesterday evening, on 20 June 2013, has caught one of our craft friends while testing his own ball EMDR's.

He underestimated the forces of nature which occur in his tests, if you put an object in high speeds.

As we previously reported, a magnetic ball can be placed in a stable magnetic field and with proper control at high speeds. This can not be done to infinity, because at some point the centrifugal forces are so great that it will destroy the material of the magnet itself.

So far so good, that is clear to all of us.  Therefore, please note the following tests for your hints and tips.

Please do not go to the limits of the material.  Please always  take a calculator at hand and realize  by calculating what surface speeds can be reached.

There was already a few weeks ago an accident, which was only shattering a smaller ball magnet and did not hurt much. 

At that time a small 6.7 mm Neodym ball magnet was brought (as measured by frequency meter) to about 750.000 rpm from the same hobbyist, R. 

Then it shattered. These ball magnets are only protected by the nickel layer...they are produced just by pressing together neodymium powder and electroplating them with a Nickel surface.

It had completely torn the ball magnet apart. 

At that time it hit only his thumb, which was not so severe, but this new explosion  after his  test with the 1 inch ball magnet now ripped his whole right hand apart. 


According to his data his room looked "like a slaughterhouse" !!! Blood sticking all over the walls !


Some splitter parts of the magnet bullet ripped through  his right hand.

At a distance of 1m the broken pieces  still stuck about an inch  deep  in the wall and the cabinets.


We refrain from  posting photos of this accident.  It makes no sense when someone is permanently cause damage to such tests. 

Blessing in disguise was that there was hit "only" the right hand .  Still bad enough. 

Just imagine if it would have hit his eyes or head !

Then he would probably have died !

Therefore respect for these centrifugal forces !

There had been  also warning voices from us in advance.

But he did continue to try such high speeds unfortunately...

So some tips to help:

How do I calculate the surface speed of the rotating object?

Here demonstrated by the following example of the first shattered sphere, because there exists a secured  data report. 

Although I have asked this before calculating the net a few weeks ago, but here again, it can not be lost and can be verified in a document.

6.7 mm diameter ball, speed limit before bursting was 750.000 RPM (ie seven hundred and fifty thousand revolutions per minute).
at 750.000 rpm the ball makes 12,500 revolutions per second (12500x60s)

Formula:

Diameter of the sphere 6.7 mm in x Pi (ie 3.1415) = 21.04805 ball Circumference in mm x frequency (frequency meter shows the frequency of oscillations per second, so speed) 12,500 = around 263.100 mm / s: 1000mm (to to get to meters) = 263.1 meters per second (!). 

The speed of sound is 333m / s!  - That one should keep in mind!  Here, then, appear enormous centrifugal forces.  (We do not know at the moment whether the end result is still to be divided by 2, and if the meter per second 2 pulses per revolution of measuring magnetic ball or just one. (See below)

Incidentally, we do not measure the speed at a measuring point in the system (because we do not want to measure the switching frequency of the transistor), but detached from the system.  This is the following dimensions:

Take any small wound with thin wire coil or choke with ferrite or iron core, maybe you go without the latter, and keep it simple in the vicinity of the rotating magnetic sphere.  On one of the connecting wires is now measured with a frequency meter the  frequency.
(Multimeter with frequency measurement)

It displays the frequency per second in general. 

That translates to 1: 1 (we are still not sure if it should be 1: 2) to the number of revolutions. 

The ball describes IMHO in its rotation actually 2 totationshifts from north to south.

It would be good if someone could  clarify this , amybe a  professional with good measurement equipment, whether one induction pulse happens per revolution or two pulses per revolution. 

This is currently not entirely clear to us.
Thanks for your advice so, we look forward to answer to this..

And now to calculate  how many meters per seconds the surface speed of the larger sphere is.
Surface speed of the example of a 25mm ball:

25mm x 3.1415 = 78.5375 x (eg) 5.000 r / s = 392.687mm: 1000mm = 392.7 meters per second (!)


This ball can therefore not achieve such rotational speeds (300.000 rpm), because they would almost certainly shattered long before .

At 150.000 RPM it still makes a surface speed  of approximately 200meters  per second.


Use this calculation to what extent this is that you can  factor in centrifugal forces and the material stress is so obviously not reliably verified.

I'm not a material engineer and not a physicist.  The centrifugal forces can potentiate the larger the sphere is of course !


So you should have the surface velocity of a rotating body always in your mind, when you play with these generator toys,
so you do not lose the respect of the resultant centrifugal forces.  A  loose magnet is like a flying bullet !


We have made the experience that plexiglass seems suitable that you can tame a rotating ball magnet in there without much wear on the plexiglass surface or the ball surface .

But when it shatteres and flies  out of the tube it is like  a dumdum bullet which also  has penetrated this material.

If you experiment with such a device you should go wisely to work and be always aware of the consequences. 

We are moving in uncharted territory here and it is not entirely ruled out, that one is exposed to great danger. 

Therefore, you should consider some precautions and then not take  the risk of the research with too high speeds !

What not to do:

Please do not attempt the limits of the material without appropriate protective measures, such as wanting to try out as a bulletproof glass showcase. 
If you have no suited laboratory, don´t try it. 

The principle of EMDR is said by Prof.Turtur certainly does not required speeds in the extreme area. 

He wrote in his instructions that the speed ,though it is expected to be over 50.000,  does not mean that one must not exaggerate the final speed. Better stay with much lower speeds and never be and wtach it unprotected by a shield !


It is important for its calculation how to set the inductance of the coil with the capacitance of the capacitors and alternating the rotational speeds of the ball or of the bar magnets of the rotor in relation. 

In our view it is not necessary that one must work with large magnetic balls because the effect can be seen almost the same with small ball magnets.

Do not use damaged magnetic balls (which had fallen down on the floor and thus might have internal cracks already, or don´t use those which came into collision with other magnets).

Neodymium magnets are brittle and often explode even if you let magnets fly against each other. !

We ourselves will build a plexiglass box from thick Plexiglas (at least 10-20mm in thickness), which can provide a good shield system and thus can mitigate any accidents occurring.

In our view, the ball magnet  EMDR is not unmanageable, so you include some precations and do not act recklessly.

Transistors have reinforcing effects.  So if you already enter at the input with huge input power, one must not be surprised at the output of the system, that it  can be a uncontrolled effect then, which are aggravated or even potentiate itsself then also.

For example, eddy current field effects, which can act like heating  the ball.
Strong currents greatly increase output voltage values ​​ect. 

Heating of the ball can very quickly occur under certain circumstances, just  within seconds. !


The question then must be asked, if the material can withstand the thermal stresses occurring in the material?
The  ball  becomes probably heated more than the jacket inside it?

If it comes to cracking the ball, which in turn can lead to the rupture then with increased speed of the ball?

This we  assume with great certainty that that happened faster with the larger sphere diameters ,
therefore we always have to make our own experiments on the fact that we must  control the temperature
of the ball magnet not getting too hot !


If a coil gets hot, you may have the number of turns dimensioned too small or sent in too much current / voltage to the input.

Measuring and metering of the input power is thus  in order.
So, if the ball floats and hoovers in the field quite safe and quiet, it is all probably  perfectly balanced.

If it comes in contact or physical stress by rubbing with friction on the plexiglass tube , yopu must be cautious with heat buildup.

The ball normaly does not develop more friction heat, which has never been a problem in our own experiments, because we used quite low speeds and it did not touch much the walls.

The higher the inductance of the coil, the less capacity the capacitor needs to have.

Note also that one can melt metals in magnetic fields with eddy currents !

But this can not be the purpose  with our ballmagnet -EMDR that one should thus heat its apartment with it. 

What you can accomplish on a small scale can be scaled up on a larger dimension.

The question is, do we need that?

Maybe one day we will come to the point that you can use electronically generated oscillations with a stationary ball in the box and without rotation.  For example for charging batteries, yes, but how do we put that into EMDR's - principle ?

It is and remains exciting, so you do not want to tarnish this tension through careless action..

So there is little point in bringing if you want to conduct research on oversized equipment.

It does not matter if I input 10Watts and want to get 200W out , or whether I put  100Watts or 200W input and then want to get 2000 or 4000 Watts out, the result would be the same, only the risk of the latter experiment is much larger than in the first case ! ( As the first case is already OU !)

If you have mastered the small system,  you also can later scale up a bigger system.

If it is flying apart  because you're impatient, you can quickly loose everything and your health. 

So we should not lose the fun of tinkering and research, just because you have exaggerated it.  Here, therefore, strongly self-critical examination and analysis of your own work is called for.

Summary

We should not blind us the joy of experimenting and tinkering by recklessly induced accidents.  Turns conscience and thought.

The two accidents should not be just a warning, they should remember that you can always pay dues at the beginning of the research but do not necessarily have to pay an unlimited degree.  It should not prevent us to do more and learn from them.  Errors make us more if we understand the mechanisms (want to) and perhaps it should be an incentive to us that what you are doing to be filled with personal responsibility and great attention.  We will not scare each other, teach or abuse went so wrong, but we want to come forward and it would be unthinkable if someone loses his actions in this life or eyesight.

It should be noted that myself the inventor of the "Ricardo charger", which therefore on the connection to the rotating ball in the magnetic field brought us called me and begged that I again specially emphasize that he always warned against it its information or has passed appliances that one may restrict the energy supply and responsible act.  He only works with 9V batteries. 

We and other groups worked with EMDR with just 12 V batteries.  The author of these lines works with a 24V power supply with input restriction to 0.3 A (= 7.2 W maximum).

We all had absolutely no problems so far, although the systems are, indeed partly operated hours per day without that there has been notable wear or overheating of the system.

We are warned repeatedly against each other within the community to tinker and publicate our previous results that one may make these sexperiments please carefully and on their own responsibility and without the unnecessary testing of the boundaries.

You can explore limits, if you want to make sure that, you secures strongly against accidents accordingly if you want to take something on you that way.  In any case, the responsibility lies with you yourself. No one takes responsibility for it from you this way.


Please make sure that a large ball may rotate much less per second than a small ball so that it can not burst.

In all experiments, which one takes on rotating parts, you should never lose respect for the physical forces.

Ensure that the ball can not be heated excessively.

So check whether your setup (coil and ball) does not overheat.

Please record all your results and experiments in a diary book so that  you can verify and reread all your results much later again...  You educate yourself so thoughtful to act if one has to monitor itself.

If anyone get harmrf it is important that you can verify the experimental setup which then can lead to a sometimes devastating results.

It also protects the other hobbyists this way. If you  throw it all away in a rage, then also the other hobbyists will not help you with that.  They are therefore also at risk even more, cause you can not report the parameters of your experiment !


R. tested in the same experiment  , how self-built AC capacitors worked with it and from this arises the question  for us now, if this Prof. Tutor EMDR system  can continue to turn the ball without further input supply  energy ??
Maybe it selfaccelerated too fast too soon this way because of the special selfmade capacitors ?


So  you will also need an urgent emergency switchoff.  Load resistance,  contactor or a fuse (light bulb defined performance) between the condenser unit and installed as emergency brake switchoff solution...

Just a normal  switch on the circuit board and in the vicinity of the primary power supply is not sufficient then, in this case
as it could go in acceleration mode too fast !

We continue to see a very big potential in this unit and an accident at least does not prevent me to further research this.

We definitely hope that the recent accident will be a lesson to all of us , but that it represents a big step on the way to our knowledge.

Everything has a deeper meaning, even though it may be very painful for the person concerned at the moment.  We sincerely hope that this will happen without permanent damage to him.

No way we're holding ourselves back, especially since extreme experiences are important in research.

A suggestion to all, can anyone  verify whether the manufactured magnetic ball beads are always pressed from powder material or are there any  iron based ball magnets that are made by melting so they are much harder and can accept more centrifugal forces ?

Is there any other more strong  material that can be used for such magnets or other negative properties , which you should be aware of? 

Temperature resistance of such magnets ect.  Information on this, please send email to info@visionblueenergy.net
or post it here as a reply...


This document is being maintained as of June 21, 2013 and is, of course, can and should be reported and published.

 
In this sense, we hope and look forward to our successful joint open sourcing of the further test results with the ball magnet EMDR  and speedy and successful recovery of our collaborator R.

Hi Stefan,
For a rotating Neodynium Magnet sphere, we need to look at the hoop stresses developed due to rotation and compare them with the mechanical stress (Tensile) that the material can withstand up to failure.
 
The general formula can be applied:
HoopStress = Density x AngularSpeed Squared x Radius Squared
 
Get Units correctly. Using SI bellow for consistency:
 
For a typical Neo Magnet and approximate numbers:
Density=7.5g/cm^3 = 7500Kg/m^3
Tensile Strength=75Newton/mm=75000000Pa (N/m^2) or 75x10^6 Pascal
Also
AngularSpeed in Rad/sec
1 rpm=0.1047rad/sec
Or 1 rps=6.2832 rad/sec
 
So as an example:
A sphere of 1 cm radius=0.01m
With density of 7500Kg/m^3
Rotating at 100000 rpm
Develops a HoopStress of 7500 x (100000x0.1047)^2 x 0.01^2 =82215675 Pa or 82x10^6 Pa
Already above the tensile strength. Smaller radius allows for higher speeds.
Eg a 6mm diameter sphere , radius 3mm or 0.003m the stress at 100k rpm is about 7.5 x10^6Pa
Well bellow the limits of failure, all else being in good condition, eg no cracks, inclusions, and so forth.
 
So be care full out there add a factor of safety 2-5 the higher the better, just to be sure, and an adequate Lexan enclosure.
 
I hope this helps.
Thanks
Mike

0. Always wear safety glasses when working with strong magnets and rotating assemblies.

1. Yes, please use Lexan (polycarbonate) plastic and NOT Plexiglas (Acrylite, Perspex) (acrylic) for safety shields and enclosures. The acrylic plastic can shatter dangerously.

2. Any rotating assembly involving strong magnets must restrain the magnets structurally, not just by glue joints. Glues fail, and a magnet can go flying across the room, and while it might not be going that fast.... once it hits something and fragments, the pieces _will_ be going fast, they will be hot and dangerous. Restrain your rotor magnets structurally _and_ with adhesives!

3. Am I reading the report correctly? The same person who was seriously injured by the disintegrating large sphere magnet.... had the same thing happen earlier with a smaller magnet and received a lesser injury? And then went and did the same thing again, with a larger magnet at higher speeds?

It's a tragedy all right and the person was lucky he wasn't injured worse or even killed .... but really......  :-\

Many of us have seen the photograph of my epoxy golf ball magnet. I believe successive coatings of linear polyurethane, perhaps pocked like a golf ball on the outside, might add cohesiveness and speed. This idea was Pirate Twinbeard's. He also suggested running the spheres in PVC couplings. Very tough material.  Golf balls travel faster with those tiny dents.


These guys are doing  exactly the same thing I was with my multifilar spirals, a trigger, power and output spiral around the PVC tube and magnet sphere. I showed the setup running at unity, looped back to source, with enough primary feedback to light a 120 volt LED bulb to around 2/3rds it's intensity. I claim this as OU.

Thanks for this warning. Fascinating these "satellite" magnet setups.

Due to the danger, iron or steel magnets might be the better choice, I assume. I was never happy with the neodymium magnets breaking and splittering so easily during my own experiments, but now I'll remember when to not use neodyms.

Yes, he had blown already a smaller magnet and got hit only lightly at his thumb as I was told...

Then he  experimented with the larger 1 inch ball magnet and it struck him real hard this time !

Many thanks for the tip with the Lexan ( Polycarbonate !)

First: the Magnetkugel-EMDR is a great design http://visionblueenergy.wordpress.com/2013/05/14/magnetkugel-emdr/, I will try to build a similar thing.

In a video http://www.youtube.com/watch?v=DMiwxJsV7Y0&feature=player_embedded they hint at OU ("the battery does not discharge although there is a load of two gas discharge tubes").

I wonder why they do not try with a capacitor (e.g. supercaps) instead of the battery. One would see very quickly whether the cap discharges or not.

I also do not understand why the "generator coil" is very far below the spinning ball-magnet.

Is someone from the EMDR-group present in this forum? Would they answer questions (e.g. in German)?

Greetings, Conrad

Hi Conrad,
I am also still waiting for some answers.


They are currently mostly on the Facebook groups like:

https://www.facebook.com/groups/266974953429136/

and

https://www.facebook.com/groups/Action4Free/

Try to connect there with them in German language...

The problem is that these guys mostly only speak German language...

Anyway, I will post new updates in english language also here,when I will get some.

Regards, Stefan.

Yep Lexan is what is used for bullet proof glass.   Since you don't need that long of a tube of it I'd suggest a tube with a minimum 1" thick wall.  I think it takes about 3" thickness to stop a high power rifle bullet hitting straight on.   So the thicker the better.   Not sure how thick stock pieces might be but it may be possible to put several sizes together one each fitting just over the outside of the next piece  i.e. concentric rings of tubing.

Listen to the soundtrack on this video. I had had this running for a day and a half with the same zinging effect. Bouncing the power back and forth in resonance! No change in battery voltage. The big spiral's a trigger and power, and the smaller spiral's  wired to a FWBR then to the source battery.

Now that is interesting.

With the toroidal winding you should not be getting very much magnetic flux leakage, but you can be driving the core into and out of saturation, and also getting some additional augmentation from the field of the rotating sphere magnet.
In other words, you might have a core-effect pulse motor, self-triggering, with the internal spherical magnet as its rotor. It's like a Steorn Orbo core-effect pulse motor, only much better!

If, that is, I am right about it running from the core effect rather than flux leakage from the toroid acting as an electromagnet.

I never understand why people who claim "no power consumption" never use a capacitor instead of a battery.

I would allow to start the device with a battery till it assumes "constant operation", but then a capacitor (which already was in parallel with the battery) could take over. Then one measures (e.g. every minute) the Voltage over the cap for a few seconds only (because the multimeter would be a load).

The capacity of a battery to drive a low power device is sufficient to do it for many days (and I have driven a Joule Thief with one AAA battery for almost 4 months), therefore "no change in battery Voltage" is a meaningless statement. It only shows "low power consumption".

It is specially bad if the tests are done with a 12 V 7 Ah battery (or even bigger batteries). To see a change in Voltage in case 100 µW are drawn will take many days and will probably be due to self discharging.

The battery voltage drops noticably right away when I disconnect the feedback loop. This draw shows up instantly, it dosen't take days.  I don't need a capacitor to tell me what's going on!


Here's what I know for sure; Current can't flow in two directions at the same time through the same wire, but it can reverse directions. I use a number of magnet spheres of different sizes. The 1 1/2 " speeds up and slows down. Looking at this video:

We can see the amp meter charging the battery as the sphere slows down and then reversing the current and draining the source as it regains speed. The charge coil then gains sway with an overwhelming back surge. That zither sound at around a hertz is the frequency of the charge reversal. While it's behaving that way in tight resonant oscillation, there's no further draw on the power source.


Even when the amp draw is rising and falling 3 100's each way, the base line voltage doesn't change. Think about it. At a steady R.P.M., once the charge coil's power reaches exchange level, there's no way for any other power to work into the circuit! The transaction is an even exchange from that point foward!

Actually, in broad terms, currents can flow in opposite directions at the same time in the same wire.
But only those currents which are not deriving their emf from the same source at the same time.
