Title: E-Orbo replications
Post by: Omega_0 on May 09, 2010, 03:30:12 PM
Starting a new thread to post my own Eorbo experiments, as the original thread is already too big now. I will also post the replication attempts of others who are not on this forum (yet), as and when I get any news about them.

So update here :
Made some changes in the design. The magnets are now in NN config and are placed underneath the rotor more securely. Now even if they get loose and fly off, the edge of the rotor will stop them from coming out.
The bearing in on top now and is better centered with no tilt.
All these justify a version change, so lets call it ver 0.3.

As expected the cemf is gone with NN config (scope shot below). Now the funny thing is, there is some cemf (in my case 10 mV at 200RPM) when you measure it directly across individual coils, by spinning the rotor by hand. It does not become zero however precisely I position the coils. But when two coils are connected in series, in such a way that their cemfs cancel out, it becomes almost zero. Connecting the coils in aiding mode obviously increases the cemf 2x.

So a good lesson learnt is, always connect the coils in opposing way.

Now there is some trade off here, NN mode means less attraction which means less RPM, so my speed at the same current has reduced by half. This is not desirable, so I will try to go back to SN mode again and see if there is any way to reduce the cemf.

Got some decent speed improvements with air gap and reed optimizations. Now its running above 500 RPM. Unfortunately the cemf shows up at high speeds.

I loosely placed two pickup coils above the rotor, both with 500 turns and 25 mm dia. These produced about 3.1 V peak to peak AC at open circuit. Scopeshot is below with some data. (Purple trace is pickup and orange one is input pulses. Note that the pulse cuts off just after rise time, the inductance is too high)

I have 4 such coils, need some hardware changes to mount them. I can't capture the scope data, its software needs upgrade, so must wait for detailed calculations till the upgrade is available.

Update: 0.6
Some important progress was made.
Good news 1 : Got hold of 8 medium-high Mu cores of material T38. This version has just one of these with 80-100 turns of 20 AWG and its rotating at 130 RPM. Rotor is same old one.
Good new 2 : SDK for my USB scope was released and I managed to modify some example code to dump the data in CSV format. At this time it cannot dump data sampled at more than 20 KS/s, so the very very fine details of waveform are not there. Anyway the data is here :

Captured data in Excel 2007 format:
http://www.overunity.com/index.php?action=downloads;sa=view;down=393

Good news 3: The Ein plot is very much similar to Steorn's demo-1, with similar "mountain ranges" and the peculiar negative going energy. This is a good verification that steorn did not play any tricks during the demo, as many skeptics still believe. I think no one else has published such plot before this. So its important one.
The current (Iin) plot shows no CEMF, finally. The Vin plot shows the flyback after the pulse ends. The spikes at the start of pulse can be due to reed switching on, but I'm not so sure about that. It should not be there.
The IV-I^2R (non-joule energy) is mostly near ZERO. Almost no power is transferred to the rotor (going 130 RPM on cheap bearings).
Title: Re: E-Orbo replications
Post by: Omega_0 on June 19, 2010, 09:32:31 PM
Setup is shown below. Vin was measured across the coil+sensing resistor Rs. Iin was measured across Rs, which is 1 ohm carbon resistor, not so precise, but I have no high end sensing resistors at the moment.
The reason I included Rs to measure voltage across the coil, was that the RDC of the coil is tiny and so is the voltage drop across it, and my scope captures just noise at such low values. Anyway Rs was included in the calculations as a part of RDC. So Rin = RDC + Rs.

I have no precision meter to measure the Rin, so I used scope itself and the Rin is an average of 800 measurements of V/I at the steady state part of the pulse.
Rin must be measured to at least 1/1000th of the ohm. Even small deviations of 0.001 ohm changes the Ein landscape totally. This is the critical part.

So things are not very accurate at this stage but everything is going towards a positive direction, so I'm happy.

More about material T38.
I'm attaching here the specs of toroids that I'm using in current version and also of the alloy T38 (which I guess is MnZn Ferrite). Its EPCOS part no. B64290L618X38, dimensions : 25.3X14.8X10 coated with blue epoxy.

Its Mu_i is 10000 and H(sat) is around 100 A/m from the datasheet. So from
H = N*I/lc
where N is number of turns, I is current and lc is flux path length, we can get the saturation current for say, 100 turns of coil:

100 = 100*Isat/lc
lc = pi*( 25.3+14.8 )/2 = 63 mm = 0.063 m
Isat = 100*0.063/100 = 63 mA

Or say you want Isat = 1 Amp, which gives N = 6.3 or 7 turns. So you would expect that just 7 turns at 1 Amp or 100 turns at 63 mA shall saturate the core completely and the rotor will not be attracted to the core at all. Sounds like free lunch.....

But, don't be surprised if the core refuses to follow the text book in presence of a strong neo. In my case the coil is taking max 2.8 Amps@100 turns and the core still shows strong attraction for the magnets ! I have no idea why this is.......... anyone knows ???? Isn't the core supposed to "disappear" for magnets when saturated ?

Either the formula I'm using is wrong or something else is happening here. This is an unknown land for me.

Good job. I'll focus on this as my first post here:

You know, I had the same problem and I never resolved it. The only thing I could achieve is what Naudin is showing in his video--when using a ceramic magnet. Could never achieve it with neos. As you know my approach is to use a pulse generator rather than the way Steorn are doing it and I blamed my pulse generator for that--the max current that it can supply is on the order of several hundred mA only. If you wanna get pulse generator capable of supplying amps you have to part with probably ten or twenty grand. Tried it with a battery and a relay and so on but never got it to work. Hope you'll be more successful because, as far as I understand, you're at least capable of powering it properly. Luckily, somehow I got into the research I'm doing right now and got away from that nightmare. I would still be interested in a pulse motor but only as a curiosity.

As for the current measurements, the metal-oxide 10Ohm resistors from RadioShack as shunts are just fine. That was confirmed with my current probe. Recall @LarryC was insisting on that (I had to verify it, though). So, you're all set on that, I think. Stay away from industrial standard shunts if you're working at high frequencies as well as, of course, from wound precision resistors. All there develop inductance voltage and are no good as my current probe indicated.

Can't unzip the file with the Excel data. The error message says:

'The archive is either in unknown format or damaged'

However, in view of the importance of Rin I don't think you should measure it by using the scope. Can't you measure it independently? Otherwise, I think you should measure the input voltage both across RDC and Rs, as you do.

Don't have a precision meter at this time. Need to invest in one. Scope is giving me readings to 12 decimal places. But the current values assume that Rs is exactly 1 ohm and any error in it will carry over to Rin obviously.

Have to go now but will take a look at it when I get back. You're quite right about that resistance. Can't we do something to have your rig measured with the instruments I have? I'm in Massachusetts right now. Where are you located?
Title: Re: E-Orbo replications
Post by: Omega_0 on June 20, 2010, 08:27:07 PM
That would be cool but I'm not in US so may not be possible.
Anyway I've decided to invest some more now and a high end meter and scope will be available hopefully soon for confirming these measurements.

Already started search for a few meters of high temperature superconducting wire. These are within reach but the equipment to cool it down to those "high" temperatures will be costly. Well, that's my future plan. Right now need to wind all 8 cores and build a new rig to mount them all........

Added second coil.
Rotor is going at 330 RPM on roughly the same peak current. Setup was not optimized for duty cycle or reed position too accurately, as this is just a quick measurement to see if everything is going ok.
Note that the net power is showing bigger hills, which means cemf is kicking in.
(First plot is voltage across two coils, in red, and current, in blue)

Effect of adding a diode to short the path of self induction:
The net energy input lowers.

I'm facing problems in measuring the actual current in the diode path. No negative current is flowing in that path after the pulse ends, but the negative voltage is snipped off by the diode, this is strange........Hopefully the circuit is correct.

Did some more research on this. It turns out that the above calculation will not apply in presence of an external field. The correct equation is:

B = mu(H+M)
or H = B/mu - M
where M is the Magnetization of the core (which behaves as a magnet in presence of a strong neo magnet)

The Hsat taken from BH-curve is meaningless here as it is measured at M=0 (i.e. for non-magnetized core). So my updated view is that the current required to make the core invisible would be sum of currents required to demagnetize the core and re-magnetize it in the direction of current. I'm guessing that this can be huge.

Post by: Omega_0 on June 30, 2010, 12:19:31 AM
Added a pickup coil. It was shorted through a 1 ohm sense resistor. This slows down the rotor. The result is not OU obviously. The setup is not perfect either. But getting close. At this stage a measurement error of 0.004 ohm in input resistance make it OU from an UU. So the next step is to measure Rin reliably.

The efficiency varies but tends to settle down with time. I don't know how to interpret this result. It seems the system is OU for some times.
Title: Re: E-Orbo replications
Post by: Omega_0 on July 01, 2010, 07:10:16 PM
Rather interesting results here.
These readings were taken at low RPMs (around 75 to 150 or so). And by placing a flat pickup coil of ~500 turns very near to the magnets (which lowers the RPM even more).

One would expect the net efficiency to decrease at low RPM, because the power induced in pickup coil decreases. But the interesting thing is, the power wasted in inductive rise and fall in input side decreases and the cemf is nearly 0. So after deducting the heat losses from the Ein, the net energy transferred is very very tiny.

I guess I have totally replicated the Steorn's Eorbo demo now. Learned many things during this built and my sincere thanks goes to steorn team.

There are still many things to resolve, and as I'm using a crude setup and not so accurate instruments, I can't place my 100% confidence on these results at this time.

http://www.overunity.com/index.php?action=downloads;sa=view;down=397

This one is most interesting, the input curve shows no slope at all, which means no energy is being transferred to the rotor.
Title: Re: E-Orbo replications
Post by: Omega_0 on July 01, 2010, 07:55:22 PM
Now the main issue I'm facing, which can spoil all these pretty curves and render them meaningless. Below are some variations of the plots obtained by varying the value of Rin (=the resistance of the 4 coils + sense resistor) by a tiny bit each time. (Note that the actual value remains what it is, it was changed only in Excel intentionally to see the effect it has)

Assuming Rin=1.465 ohms, Ein gains an upper hand and we have CoE as usual.
Increasing the Rin just by 0.01 ohm, makes both slopes equal. Increasing it a bit further make Ein negative (a gain, instead of a loss, which could be very interesting if true). So the results are above the noise floor but measurement needs strict tolerances.

An error of +/- 0.01 ohm can make results invalid. If you see the steorn's plot, it is a lot neater and would need even higher error margin. One wonders how they measured Rin, and whether any error in Rin measurement was responsible for their claim of OU and they don't know this.

More experiments are needed.

Excellent work!  If you could measure the instantaneous value of the resistor during the experiment, with an additional channel, then we would know if the OU is real or not.  This would allow us to use the instantaneous resistance value instead of a fixed value for the resistor.  As we can see with your data, a very small change in the resistance can make the results invalid.  Do you have a 4 channel scope?

Thanks,

No I have a two channel USB scope with ordinary probes. But you must have noticed that I'm using scope already to measure the Rin. I'm using the steady state part of the pulse to get values of voltage divided by current and then average many hundreds of these values. This ensures that the Rin is measured at runtime and at operating temperatures.

Here only problem is that the current value again depends on the sense resistor which I must assume to be exactly 1 ohm. I'm anyway investing in a good milliohm meter which should resolve the accuracy issue.

Below is another plot for a experiment I did today. The red line shows the net Ein with rotor a bit farther than in usual place and rotating at a slow speed.

The blue trace shows the net Ein when rotor is place far away (4 inches approx from the coils), so that it does not rotate and does not influence the coils but is still able to trigger the reed. It was spun up by hand in this case.

The important thing to learn here is that the slope of the trendlines of these traces in both cases is almost exactly the same. The slope represents the net power being consumed. This means that the coils are consuming same power with or without the rotor.

This also means that no power is being transferred to the rotor during normal operation and the rotor is spinning for free, just as steorn claimed.

@Omega_0,

No need to repeat you're doing a great job. I'm trying to convince prestigious labs to try to reproduce these experiments but so far I'm only meeting with complete lack of willingness. They don't want to hear about it. So, I just wanted to let you know as what the status of this is as of now. I'll continue the effort and will keep you posted.

Wonder if you're following the other thread where I was hoping that somehow this discrepancy will show up theoretically. That would've been the only way to raise any interest at all. So far to no avail. In addition, I'm studying the possible sources of experimental error and it very well may be that the 8 bit scope I have is just of not enough sensitivity for such studies, despite the current probe I got. Even Steorn's equipment may not be of enough accuracy for this kind of claim. This is something that has been bothering me from the get go but that's the most I could afford. What do you think about that?

Steorn has a bad reputation, and free energy/overunity has worse. So I suggest not to refer to these terms when trying to convince the established guys on the matter. This is at most "an accounting discrepancy in energy" at this stage, and should be called so.

No financial gains are there in such studies, so no one will waste their time on this. Only the curious types will touch this. I agree with you that the precision needed to measure the quantities here is extreme, and is beyond the capabilities of an average hobbyist, which includes me. There are so many issues of probe loading, accuracy, tolerances and what not, which cloud the results and you are left with nothing but uncertainty.

I do read the other thread and you are doing a great job. Your persistence is remarkable, this quality is most needed in OU research. As I posted there a few days ago, the results you are getting are below the noise floor. You can't be certain about them. If there is really an energy discrepancy in "steorn-like" systems, it will show up in a variety of circuits, but it will be below the range of classical instruments.

Either one must devise something which can operate above the noise floor and produces very solid measurements or one must lower the noise floor by controlling the environment and using non-intrusive methods. Only a big lab can do that.

Update at last...
I've gotten hold of a 4-wire kelvin bridge micro-ohmmeter which can measure up to 4 decimal places and is calibrated using a standard resistance box at the factory and the calibration can be traced back to at least national level standards. Another news is that, now I'm a proud owner of Metglas cores, both MAGAMP and MAGNAPERM (its part no. 2510P4AS and 2510V4AF). A dozen of them :D

So first thing I did is to measure all the resistances involved. It turns out that my earlier estimates do not match well with new (more reliable values), as I doubted. Now plugging in these values makes OU disappear completely. So a new struggle starts now.

Earlier I was using the scope values to get the Rin (= resistance of sense resistor(Rs)+that of coils), assuming Rs = 1. So I always got IV-I^2R = 0 perfectly when a DC was passed into the coils and current and voltages were measured with the scope. Which may mean that the earlier plots are still valid, but there is no surety that system is OU in reality.

With actual Rs and Rin values measured from micro-ohm meter and pure DC applied, I get a residual net energy (Pout<Pin, See the attached plot-1), which means the readings must be compensated to get a 0 net energy (Pout=Pin, see plot-2)

These baseline measurements are very important. I must measure every resistance at actual operating temperature to get an accurate enough reading and then must also compensate the scope values to get an agreement between micro-ohmmeter and the scope.

After that I must apply these corrections to the pulses measured during an actual run of the device. Its really too difficult and delicate affair.
Title: Re: E-Orbo replications
Post by: Omega_0 on August 18, 2010, 08:40:56 PM
For those who are wondering how I arrived at the compensation values (dVs and dVin above), here is the calculation:

IV part
(Vs+dvs)*(Vin+dvin)/Rs----(1)

I^2R part
(Vs+dvs)^2*Rin/Rs^2------(2)

condition ... (1)-(2) = 0

(Vin+dvin)*Rs = (Vs+dvs)*Rin
VinRs - VsRin = dvsRin - dvinRs ----- (3)

plug in the known values -
3.5933*0.974 - 2.5244*1.3296 = 0.14343196 = dvs*1.3296 - dvin*0.974
0.14726 = 1.36509*dvs - dvin
dvin = 1.36509*dvs - 0.14726 ----- (4)

So (4) gives values of dVin for values of dVs, and this formula is used in excel above, with reasonably guessed small value of dVin.

I'm facing some problems even though I'm able to measure voltages to 12 digit accuracy and resistances to 4 digit accuracy. The sense resistors heat up and vary randomly. The scope probes pick up spurious signals, and display small but random offsets. No two readings are same. Note that we are talking about extremely accurate measurements.

The scope and micro ohmmeter never agree.

Now that I don't have a million $ lab, I must give up measuring accurately. The other way is to increase the output so much that it all makes sense in the presence of all the noise and inaccuracies. For that I'm building another test setup with lot of output coils.

@Omega_0,

Don't give up. You're one of the few competent people here quietly doing superb research. Wonder if something can't be done to persuade Sean McCarthy to let you borrow one of his Tektronix 7104 scopes with the current and differential probes? After all you're the first independent researcher to confirm his results. What do you think about this idea? Don't know where you're located and whether or not you can get associated with a university lab but maybe some of us can write to Sean and see if he would be willing to do that. I don't recommend, however, signing of all those nda's and skdb or whatever, if that would be the condition.

After all you're the first independent researcher to confirm his results. What do you think about this idea?

Omnibus,

I can't say I've confirmed their results. Simply because their results are unknown to public, there is no data, no measurements, no calculations... only marketing. I've only replicated their demo traces, with some assumptions. This can be either totally accurate or can be a total mistake.

Now, I'm putting this disclaimer here because I don't want people to take my observations as confirmation of Steorn's claim and invest in Steorn on this basis (and suffer any loss or disappointment).

Your idea of asking Sean M for providing help in this replication shows your best intentions really and I appreciate your support. I'm located in far east and live hand to mouth most of the time, so any kind of travel and offline collab is impossible at this time. There are more qualified and resourceful people who live nearby and we should promote them, if they wish so. Moreover I highly doubt that Steorn is interested in getting any kind of independent verification, else they would have done that by now.

Secondly I'm against signing NDAs and that's why did not apply for their license. But if even one credible person reports anything positive about this tech, I'll do that too. So far no one has come forward with any results. I'm not giving up on the project, just giving up the measurement method that assumes too much of stuff.

Some more improvements in the setup:
Cores are now vertical and are mounted on adjustable arms to position them perfectly for minimum CEMF. The arms move like a record player arm but only within a few mm of the center line of the magnets above on the rotor.

Also mounted are 12 hand wound air core coils, placed above the rotor. These are wired together in three sets of 4 coil each. These will hopefully provide 3 x 1Vp-p output on open circuit, and will drive 3 load resistors. Waveforms from two of them are shown below.

Hoping to get ample output this time, which will take care of tolerances at the input.
