No problem, just thought I'd ask, anyway.

As with many developments, there are number of variables that need to be understood and
optimized to realize a target application. But in order to organize a systematic approach to
finding the best solution, no matter the approach, you need to gain an appreciation for the
underlying theory and the many interactions.

The "Cook Book" for the LinGen, and other similar devices, is still being written!

However, as can be observed from some of the posts now appearing, at least a few basic concepts
are being understood and discussed (B-H Curves, electrical steel, magnetic circuits, controllers, etc.)
which I do find somewhat encouraging.

Many thanks for all the hard work.

A couple of hours processing time and you should have that book completed.
When you have a new interface to forums other than SMF, please do publish
to Beyond Unity.  Several good builders there that would take your work
and transform it to real hardware for 3rd party testing and validation.

Dog-One,

Thanks!

It's apparent however you've never done design work - "a couple of hours processing time
and you should have the book completed" - WELL,  maybe cows will fly soon!  ;)     
HEY, YOU FORUM GUYS STILL CRACK ME UP!    :)   

Keeping the design focused on the application is challenging but a bit of fun (40V Lithium
replacemen or running your refrigerator). 

There's some more to do however (legal [gov] and royalties) to protect all those involved;
but it's moving along.
I'll attach an old story that "carbon copies" my philosophy.  :)

Thanks Jimboot,

At the risk of more abuse:

F.Y.I.

LinGen "HIGH VOLTAGE CAUTION"

Just thought this Warning should be posted!

SL


Good preliminary result!
There are several questions:
- What is the ohmic resistance of the output winding?
- What is the peak excitation power?
- What loads did you connect and the level of voltage drop under load?
- The ratio of the turns of the excitation coil and the turns of the output winding (in your version, the number of wires in the groove of the excitation and the wires in the groove of the output coil), this is necessary to avoid the effect of the proportion of the ratio of the turns of the transformer).

Hi Rakarskiy,

Good to hear your still with us - I worry a bit considering your where abouts and the situation.

Note that the "High Voltage Caution" pdf was posted as a warning - saturating the inputs with a "light"
load (100K ohm || 10uF Capacitive) can result in lethal voltages on the LAP winding (400Vpp at 1A).

That can be hard on equipment and it's enough to kill you.

Most of your other questions are answered in the pdf. Load drops appear to be the standard simple series/parallel
circuit combinations (LAP winding into whatever the load is). E.G. the 10uF||100K changed the V/I phase as expected.

So far there doesn't appear to any surprises until you reach the material saturation but the # of coil turns and ratios
seems to be very important (sensitive) which stands to reason. It's a trade-off balancing act like most devices.

The large rise in output may be due to a resonance but that effect still needs further investigation.

Input Flyback (some call it BEMF) recovery is not shown in the pdf schematic but it looks like near 80% can be
re-used with a simple diode scheme - maybe more using switched FETs - TBD.

Still a work-in-progress as time permits, but interesting enough thus far that I'll do a few more tests with various configurations, including some different physical schemes.

How's your and your friends stuff coming? Good I hope! Looks like he has access to a Laser Cutter. Nice! 

Take care,

SL

Hello SolarLab!

I would not rush to conclusions: P = UI = 400V * 1A = 400W (This is a serious statement).

For such an indicator, an appropriate core is needed for the corresponding Ф=BS magnetic flux. Further, your 400V peak value should correspond to the formula E = 4.44 Фf.
You modestly kept silent about the resistance of the circuits, the cost of excitation, the places where the magnetic flux from the wires of the phase winding disappears.

I won't jump to conclusions, I'll wait for more serious tests of your generator. I hope to see a picture of the device to see the scale.

Sincerely, and I look forward to your new data, with more detailed design and calculations of the corresponding episodes of the generator.

Why does my output power taken from the rotor depend on its position inside the stator?
At what angle is it rotated inside. I think you do too.
Doesn't this mean that we consume something else from the stator besides the rotating field ?
This is direct induction as in a conventional transformer.
It is could for you to achieve that at any position of the rotor inside the stator, the output EMF does not change ?
This will mean that the energy in the secondary is available only due to the rotating field.
And nothing else.  I haven't been able to achieve it yet...

saliency

Having salient features, meaning a nonuniform or unsmooth shape gives different reluctance for magnetic path dependent on relative angular position causing magnitude of flux to vary.

My guess. I don't know what your parts look like. Also, isn't input to rotor and output to stator? Although in transformer it can be either way.

Yes, that's how it is, perhaps.
So how do we want to use only rotation if we can't get rid of the parasitic interaction?
Or we do not know at all, what we using.

Hi Rakarskiy,

I agree, a little early in the development to rush to any firm conclusions, especially with respect to a detailed
theory-of-operaton or optimum performance parameters.

Since the initial investigation used several different CAE tools, I'm going to go back to the beginning analysis and
use only the lastest CAE tool. This has to be done for continuity and documentation anyway; and it might
add  bit to my limited knowledge base and tool expertise.

In the mean time, I'll wait for this groups Analytic Solutions or some results from a physical Prototype build.
Then I'll have something to reference against - which was the original intent of comparing various design approaches.

Regards,

SL

Attached a graph of "Stranded wire loss for both LAP turns and Coil turns (turns) for "turns" - Linear step from
10 to 700, step=50; and "lap_turns" - Linear step from 1 to 400, step=30. This relates to your "wire_R" question
I believe. You can see why a simple answer is a bit diffiult to respond to. Just for reference so I won't try to size it.

Hi Kolbacict and Bistander,

Thanks for the great question (... position inside stator). Got me thinking about the physical
configuration with respect to the LinGen and the saturated output anomoly - fooled with the offset
a bit just now (Magnetostatic) and you may have hit the JackPot!

More later, as it develops - Free Beer if it works out... Thanks Again!

PS - also fixed the cartoon over-size.

Hi Rakarskiy,

A bit more in response to your comments and concerns. The attached notes are from a COMSOL course a while
back as I recall - can't find it on the internet however; so it's attached.

Covers both Analytical and Numerical approaches to a Fault Current Limiter design but the first five chapters are generic
to developing most devices of similar structure, including the LinGen. It's quite comprehensive and well done IMHO.

You're probably intimately familiar with most of the stuff covered however it might be a useful read for others.

Hope we can compare your analytical data with my numerical data sometime soon - I'm curious to review the results.

Use beam modulation  with certain frequency,and you can measure speed of rotation magnetic field.

bars of transformer steel (sets of that plates) were placed between the stator and the glass tube of the kinescope.
Similarly, as it is done in mechanical magnetic gearboxes.
In order to increase or decrease the natural rotation speed of the field.
The picture on the screen has changed, but I have not recorded a clear change in the rotation speed.
Interpret the picture , the data received is not enough mind.
If you don't want to help ме, I have to myself... :)
