Holcomb Energy Systems:Breakthrough technology to the world

[Ufopolitics]

So, in summary, the LinGen and HES devices do not need, and would not bennifit from, these Exciters or Sub-Exciters.

Thus the LinGen and HES designs are, in fact, what they are, then. That's what I thought.

Could get comfusing if you mix old conventional stuff with these new Holconb techniques.

I must have missed your previous post where you explained all that.

SL,

The LinGen and HES, ALL work based with exactly the same technologies related to Magnetic Field Induction, ever since Michael Faraday discovered them back in the 1800's...up to now, they are the same thing.
And so, of course they will greatly benefit from the exciter system to be incorporated to them.
Otherwise, I wouldn't being spending my precious time with all graphics and explanations in such great detail.

the Exciter System on a typical Generator, as bistander wrote before, is the PSU plus Sequencer of the Main Generator Induction Field at Rotor...but, on top of that, it is the Amplifier or Gain Mechanism, which stands up to all back forces (BEMF) and face them, by increasing its power whenever Output is loaded.

Hi Ufopolitics,

Thanks.

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 ).

On the LinGen Output side, the Stator LAP Coil feeds an Inverter circuit ( not shown on the "Simplified LinGen Bock Diagram") that
produces a regulated AC or a stabilized regulated DC Output as required. Similar to those found in modern ICE Inverter Generators
these days. Having studied these inverter types of generators a bit I haven't found any evidence of a the so called "ES" but, then
again, I wasn't looking for such a scheme. Will check again more carefully, since it may prove to be another way of boosting
output - every bit helps. Not sure where or how the "ES" would be implemented in the LinGen even if did prove to add some value.

Speaking of percious time I know exactly what you mean. The 35W Gantry Laser Cutter is here so it needs some major effort to bring
on-line in the form of cutting laminations. But first there are a few more CAE design passes that are needed to perfect the
"tooth patterns" with respect to the lamination foil materials that can be cut. Hopefully the Laser cuts OK since it was affordable.

Referencing sections in Lipo's "Introduction to AC Machine Design" book since this stuff is a bit hairy at best. Chapter 3. shows a
less complex design method for a symetrical machine, as opposed to Chapter 9.'s "Calculation of Useful Flux Per Pole method." 
Hope to have a pseudo CAE "final pass" done soon so I can get a "Beta-#2" using laminations completed and ready for tests.
"Beta-#1" used a pressure molded/sintered powder SMC which was not easily reproduceable in the Lab, had to be machined
and cost a fortune in prototype quantities. That's what prompted this "in-house" Laser lamination approach.

Anyway, your notes regarding the requirement for "ES" are greatly appreciated; but to start another complication at this point
without fullly understanding the requirement, plus, considering the LinGen so far looks good the way it is, the "ES" modification
at this point is probably not needed. After a little more study and analysis if it is found to be of value, it can easily be simulated. 

Going to be very busy around here for the next while! Sorry for the long rant but it should be the last one until I'm done Beta-#2.

Thanks Ok SL.

1-Does the LinGen driver signal is a DC modulated like a 3 phase through FET's?
2-Or is it a 1,2,3...# of total Poles of Primary to then repeat the sequenced DC Signal again?

In whatever ways, an ES would work fine...However, #1 would be the ideal one to build and test.

Imagine you have your very low input V&A coils as primary low signal, connected to Driver...then these coils would induce another set of coils (ES) but a bit thicker in gauge and more turns than primary, they (ES) are not connected directly to any input...they just receive an induced signal from Primaries as they (ES) are all looped to small AC Caps, each independently...and they would increase their V&A over primary.
Now these set of Coils would be the ones highly inducing the Output Coils, while your main Input will not rise, nor drop under load of Output Coils.

This is sort of like a "Pre-Amp" stage in Audio Amplifying...but more, because they also transfer the displacement of Field Signal.
It is like a "Buffer" in between Inductor-Induced Coils.

Hope this simple explanation would enlighten your view.

Some good ideas Ufopolitics, well worth trying once Beta-#2 is done. Don't want to get off-in-the-weeds just yet.

The LinGen in it's current form uses the timing scheme shown in the sidebar of the "Simplified Block Diagram."

Tried a few other timing schemes and it appears there is lots of room for experimenting here. Sort of what prompted
the design of an easily programmable STM32xxx based microprocessor Controller. Will likely run out of I/O if more
coils or other signals are added but the upgrade to more ports is straight forward - drop-in a new chip (these are
demo boards from STM so no re-layouts or other nonsense; just add another connector and wire harness).

More coils, etc. can be added without too much trouble but the Pole Shoes and tight tolerance might require a change to the
lamination design - not a big deal now that I have the cutter - re-design and re-run another set.

A third design (Beta-#3) is in the works. This is a major redo - opening up the Rotor (both ends exposed to the Stators [2])
similar to Figuera with a single unit stack of (a) Stator #1, (b) Rotor (open top and bottom) and (c) Stator #2. This eliminates
the exposed (useless) ends of the Stator LAP windings. The CAE hasn't finished the detailed analysis (many days on an old
laptop) so we shall see. Hope to try it on the Workstation when I get a chance.

Appreciate your ideas and explainations very much - gets the mental juices pumping as well. Thanks and keep them flowing!

BTW, the inverter has a feedback such that when the output needs to increase, a signal is sent to the Controller which, in turn,
increases "something" - pulsewidth, input amplitude, input current, etc. - still TBD.

Anyway, gotta go for now...

Laser Cutting - pretty amazing! WOW...
