Laser Cutting - pretty amazing! WOW...

I wish you good experiments! May you succeed!

In the LinGen driver output circuit, after the MosFets, there are Snubber Diodes (attached to the Stator Coils [N1-4, S1-4]). These are
not shown in the "Simplified LinGen Bock Diagram" posted earlier
( https://overunity.com/19069/holcomb-energy-systemsbreakthrough-technology-to-the-world/msg573159/#msg573159 ) but run
across each Coil input to ground.  Pretty much standard FET protection from Flyback Spikes (BEMF).

This arrangement may change a bit in an effort to somehow (adding more diodes or FETs) use the Flyback Pulse to drive the
B_remanance/H_{c coercivity} back to H₀ for each cycle; if thats possible, or, if it is even needed - TBD. The B-H Loop was posted earlier
( https://overunity.com/19069/holcomb-energy-systemsbreakthrough-technology-to-the-world/msg573227/#msg573227 ).

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.

The AC (circular) one is a bit more complicated,  the poles are still  excited in the same sequenced way as the simpler DC (LinGen) but the north and south poles are rotated one step every sequence and depending on how fast you step (rotate) you can get 50 Hz or 60 Hz or any Hz.
In the HES linear DC (LinGen) poles always stays in the same spot.

Good stuff SL!

Just remember to insulate between the laminations with a thin spray of something, otherwise eddy currents will creep back into your equations.

Also on your driver...

I would recommend using half-bridge modules powered with a bipolar power source.  That will give you more flexibility software-wise to dial your system in.  And with your microcontroller, if need be, snag some D flip-flop chips, setup a shift register and let your microcontroller provide control signals and clocking to that.  I always liked using the old Cypress PSoC 5LP because it has built in programmable logic (UDBs) that can be configured any way you want--no external chips required.  Anyway, just a thought.  Looking forward to seeing your build and initial tests.

Pretty much everything regarding my development of the LinGen is found in the 12+ pages of posts on the Overunityresearch
Re:-Holcomb and other FE technology debate thread. Some good design and development information can be found amongst
the trash. It will answer your questions.

Here are some links [probably missed a few] related to the analysis evolution:

Flat Solid-State Rotor WO 2018 134233 Holcomb (19 May 2022) 

Includes Timing and Sequencing.

"Start our Design Intent Document (DID) by interpreting/reviewing the patent to gain as much information as possible."
"The following six (6) attachments outline some of the prime information found in the patent review that can be used in the
design evaluation. Also consider the device target audience is powering a cell phone, therefore the overall physical size, to
some extent, is provided."

The development sequence followed a few logical steps in an effort to better understand and varify Holcomb's claims.
Computer Aided Engineering (CAE) was employed in order to quickly confirm various aspects of the Design Intent [DID].

There is not much more to be shared on the Forums by me so you all will have to do the best you can with what's been given
and what's available elsewhere.

The device has been analyzed, simulated and tested in a BrassBoard. The time has now come to optomize and build.

Good stuff SL!

Frankly, I do not have the time to continually repeat what what has already been presented. Plus, I can not respond to every,
or any, comments and suggestions that are intuative to one-skill-in-the-art; - thanks - but all these suggestions are stuff that is common knowledge.

Good Luck to you all!
