Holcomb Energy Systems:Breakthrough technology to the world

[bistander]

Perhaps their "electrical metal" is MetGlas or similar ?  Maybe that is the difference...

Metglas doesn't lend itself to laminations having complex shapes as seen on Holcomb's photos. You pretty much have to use a coiled core, like a roll of tape. I doubt the difference, or secret is material. But Holcomb's website descriptions did mention Metglas, but as a shield, IIRC.
When they did the side by side comparison test against the plastic core material, I think they stated the electrical grade silicon steel sheet used, a common motor lamination type, again from memory.

Hi Rakarskiy,

You commented ^{"No simulator takes into account the inertia of the magnetic field of the core."} I'm not sure what you
mean by magnetic field inertia but most professional simulators do take pretty much everything into account.
A few examples are found below.

There are several professional CAE Software Suites that do pretty much the same analysis.

Most Colleges and many High Schools now have at least one of these CAE suites and offer training classes and
night courses. You would have a hard time now days finding a job without this skill set.

Video examples do not yet involve a rotating or sliding magnetic field since this technology is still relatively unknown.

There are probably thousands of videos on Youtube relating to CAE Simulation and Analysis. Unfortunately I do not
have time to discuss the subject in the threads any further - my time is better spent on finishing and testing the
designs.

Not trying to be "dick head" here but the "LinGen Course" will be available soon and all the questions are
answered there!

I admit that was just a guess.  Metglas does seem to be in a thin ribbon form:  https://www.hitachimetals.com/infrastructure-energy/clean-energy-technology/metglas-amorphous-metal-materials-distribution-transformers.php

Hi, SolarLab!
I do not argue that the magnetic flux, even in dynamics, will be modeled very close to reality. I meant the simulation of an electric circuit and a magnetic circuit together in dynamics.
I encountered strong discrepancies between software calculation, engineering calculation systems (on paper) and reality.
Holcomb, I think it was not in vain that he complained about solving problems with reactance, when controlling the operation of magnets. I also encountered this.
Sincerely.

Holcomb patent,that somebody posted wrongly a few pages back..

You need to give in the name during saving as
