Hi SL,
Please confirm that I am understanding your sequencing the way you intend it to operate. For reference, I attach a cropped image of the sequence drivers and coils from your diagram linked in the quoted post. You have 8 coils, 8 drivers, one coil per tooth and 4 teeth per pole and therefore 2 poles. The top 4 coils are only pulsed in the shown polarity such that the top pole, using coils 1 - 4,  will always be North. And conversely, coils 5 - 8 on the bottom pole will always make that pole South. Am I reading this correctly?

If so, this is a significant departure from Holcomb's description of sequence found in the patent application for the 16 tooth 2 & 4 pole rotors (circular). I do not believe the method represents a linear version of the RMF (Rotating Magnetic Field).

If in fact each pole does not swing polarity (N to S to N to S ...) then there are implications seen on the B H curve.

Your comments would be appreciated.

I really do not see that much of a "wow" here...by the fact that LinGen does not swap polarities...
Figuera did it like that, way back in the 1900's...except, He did not have the LinGen "Stairs like" setup, with just two cores, but He arranged the electromagnets next to each others, in separated groups, having separate cores for each pair, however, still facing each others (Inductor-Induced) but, ALWAYS keeping the same polarities (North's are always North & South's are always South)
The rotary switch of Figuera was only pulsing the High-Positive end (only one brush) while all coils other terminal(s) were connected at all times Negative from Source.
Here I see same deal, except using FET's and a micro-controller...a bit more "sophisticated" but the same, exact final result.

So, resuming, here Induction works based on a Field Expansion (when Coils are peak energized) and a Contraction (when it is collapsing or tending to)

I have done Figuera in many configs, and it does generate induction this way.
Maybe this way of having all coils mounted on a single steel core for each (Induced and Inductor) will have more success.

Cheers

Why did you decide that Figuera does not change the polarity, or rather the direction of the flow? In my research, I just came to this particular system.
The problem is to follow the linearity of the change in magnetic induction, especially in a static design. The second problem is that this linearity should be with the load.
I also consider a pulsating change in the magnetic field from "0" to a maximum and back. Again, this is all, still needs to be connected to the phase and load circuit.

Rakarskiy,

I did not "decided"...Figuera did...

Figuera just commutates through an ALWAYS Single Positive Brush, while ALL the other Coils terminals are connected to negative ground.
The commutator is wired in order to pass by the resistors or inductors in between for 180°, to deliver the ups 180° and downs 180°of the signal....which looks like two inverted square Pyramids.

Man, I did Figuera like 10 plus years ago...in real Lab Testing!!
Sorry, but you can not argue with me, how Figuera works...because I have tried every single possibility out there.

Your comment:

"If in fact each pole does not swing polarity (N to S to N to S ...) then there are implications seen on the B H curve." 

Your answer:"Do you realize that the steel would be working on minor loops regarding the B H characteristics?" 

Thanks for your help - a great explanation ( ) and - a super work-around/solution ( )   

BTW, the CAE provides a very good picture of whats happening (each nSec) both inside the device material and in
the air around the device - no minor loops (what ever they are) were spotted.

See the gif annimations posted earlier.

Also attached 3 Time Step Magnetic Field Intensity plots. Rotor is clipped - only Stator & LAP are shown.
Plus, LAP [Induced Coil 9] output & all 8 coils. Stepped looking Blue Trace (Coil9 - LAP) is due to low sample/analysis
rate in CAE.

Included the ending sample cartoon as well.

Hi SL,
The highlighted passage indicates that you do know to what I was referring. Sometimes (often?) I try to determine where you're at before spending time drafting a response. It'd be nice if you provided concise answers.
I'll post a graphic which I lifted from here: https://www.researchgate.net/figure/Comparison-of-simulated-FORCs-dashed-lines-and-FORCs-from-HysterSoft_fig3_273143832
It depicts a family of minor loops on a typical B H hysteresis curve. Since the excitation you're using, as I understand it, keeps H positive, the steel in your device is working on a minor loop located in the first quadrant.
I guess this is o.k. I am curious if you realized it. To my knowledge, no conventional electric machinery utilizes such a strategy. As to why? My intuition is that it underutilizes the iron, to the point of requiring twice the mass. Seeing as how yours is not conventional, I don't know that penality applies.
Furthermore, Dr. Holcomb claims his excess energy comes from this alignment of domains 250 times/sec. Might this minor loop excitation limit this energy?

Hi SL,
In the second 8 msec period, no coils are on, correct?

The sequence is arbitrary (programmable). Analysis used the sequence shown above (each of 4 - 4 sec ON, 4 Sec OFF,
each pulse is staggered by 1 msec).

Good paper re: Hysteresis - when you analyze the GO-35ZH135 or similar material with a DC pulse what do you come up with?

What would the curve look like if it were operated in the psuedo "linear" part of the curve (1.0T for example, no saturation)?

How would you use the BEMF to bring the hysteresis down to near Zero for each cycle? Would that really enhance the
overall device operation?

Are you actually building, or planning to build, a LinGen or similar device? Or is this just a curiousity on your part? If your building
one, or have a team doing the same, are you going to Open-Source it? And if so, any idea when?

I've never had the occasion or need to do so.

Often such B H curves use logarithmic H axis. Attached is such for your steel. From: https://www.scribd.com/document/410260823/Electrical-Steel-GO-35ZH135-xls
Also note these curves only show the ascending line, not hysteresis. So operation keeping below 1T would resemble that.

How would you use the BEMF to bring the hysteresis down to near Zero for each cycle?

I would not.

I have no idea what the operation of the device is.

I don't build things that don't work. And I have no convincing evidence that any HES contraption or replication works. So no, I do not have such plans. Should I have proof, which would be great, I'll make plans accordingly. It is more than curiosity. Basically I am attempting to help those enthusiastic enough to pursue this OU dream, so their efforts are less wasted, by sharing my knowledge and experience.

bistander,

WHAT EVER YOUR POINT IS - YOU WIN - GOODBYE! 

You can't or won't answer simple things with any technical
ability or explaination - so be it.

When you finish your reproduction please post the results. If I'm still
here I will enjoy reading it...

Oh sorry, just noticed you don't build anything that won't work! Pretty
lame - let someone else do all the work first - then coat-tail!
Really Lame!   Of course, here you have a lot of company - LAME!

Maybe your Arm-Chair pseudo Engineering (mostly stupid comments) should follow
the same philosiphy - do and say nothing until you know how things work.
 
Too busy right now for this nonsense!

SL
But I do feel compelled to quote some useful wisdom from "Mark Twain"

Hi SL,
You obviously don't think there is value in knowing what you're doing. That's ok. Carry on. Let's play *who's stupid now* in a couple of months.
