One last comment on this and then I'll shut up about it.

Bi,
Why not use stainless? Cost. Mu-metal could block the path by increasing the reluctance.


Cadman,

Just the opposite. Reluctance is inversely proportional to permeability. Mu metal has much higher permeability than electrical grade steel. Therefore replacing core or shaft material with mu metal will lower reluctance.

I think a linearly traveling magnetic field within a magnetic field
is one of the keys to the HES or am I wrong ?


HES does it one way, here's another way.

That's an excellent video and explains a traveling magnetic field really well. However this technology has been around a while and one would think if there was an anomaly it would have been found by now. I was doing some similar experiments on shaded poles which can also produce a traveling magnetic field but the shading coils produce more losses.

Hello Bistander,

Yes, Ok, exactly like you have said..."to control the Flux pathways"...thanks, I understand that I am setting an air gap between them, however, when magnetic circuit is closed by rotor, it will comprehend more stronger (related to flux strength/flow) the tooth which are closer gap to rotor drum face...is what I believe...am I wrong?

You or Solar Lab could put that design in FEMM and see what I mean.

Yes, first graph is wrong related to number of tooth...it is supposed to reach 6 tooth, like shown on second image.
Remember the field according to brushes angle I have, have two positions for the -/+ electric poles which defines the field angle, which I could narrow or set it wider, I only have two positions.

Not a comprehensive anything - simply a 2 cent approach comment.

https://www.ansys.com/academic/students/ansys-electronics-desktop-student 

Run Ansys EM Student 2022 R2 | Ansys Electronics Desktop 2022R2. 

{Optional step: Open examples - Maxwell | Actuators | Rotational_actuator.aedt  => should be ready to analyze.}

Project | New [from the ribbon] Maxwell pulldown | Maxwell 3D (opens design desktop) 

From the "top" ribbon - "Help" | Maxwell PDFs | Maxwell Help 

In the PDF, Chapter 9 - RMxprt UDPS (user defined primatives) and Chapter 26 - Getting Started with RMxprt [read]

Next, back to Ansys program (still open) | from upper ribbon select "Draw" | User Defined Primative > RMxprt, now
select the type of rotor, core, coils, etc for your design. Fill in the parameters as required.
Note the bottom line of the parameters list usually has a "multiple choice number" to select options [0:core; 1:solid core
and so forth]. {Only a starting point to get you going.}

This is an aid in setting up your design - motor orientated - but you can select the windings, current, terminals, etc.
to accomplish your Holcomb configuration. 

Student version might not have enough poop to do a complete rotary design configuration - so some intuition might be needed.
Maybe restricting the mesh size, etc. and partitioning will keep your size limits within student limitations, don't know. Try it, very
little to loose and you might learn something in the process. 

Holcomb used a CAE firm/university in Australia to assist in his development.

Why bother with this approach (it's an option, even if you're the smartest person on earth and know every bit theory and practice
there is to know) because - you know your design will work before spending one dime; you have the drawings for the laser cutter
(saves money on backend engineering and Laser GCode generation) and you have a serious head start on the insitu testing and
varification! You know how it works, what to look for, and how to look.

Just a 2 cent comment on a tried and proven approach, that's all!

 Noticed the "open examples" - maxwell | actuators | rotational_actuator.aedt  opens desktop in a reduced window;
maximize this window. 

Also, the model is in wire frame - right click on a blank spot and select "View" then select "Render" (near the bottom
of the list) | "Smooth shaded", or just use (F7). 

Project Manager | Rotational actuator (Magnetostatic) already contains "Results" plots and "Field Overlays" | "B" | - Vector1 and B1
cartoons - but the solution must be obtained first to display these === right click "Analysis" and select
"Analyze All" - save the design in a temp location first.

To quickly see the solve time, results, etc (lower ribbon | Results | Solution Data. Profile shows solution took
about 01:23 on this PC - memory 62.1 M, Tetrahedra: 24954.  (well below student limit)

Some good Tutorial example videos, etc. are found on YT (Bishwas Basnet, kamyar K, etc.)

I checked with the Aussie distributor of ansys leapaust.com.au which is the same mob that did the modeling for Holcomb . They did it around the corner from my office at the time. Amazing. No other os support unfortunately.

I agree.  Been using Linux for over a year now with no reason to ever go back to windoze.  I am sure there is an equivalent program for Linux as many academics and professionals use Linux.  I'll see what I can find.

It seems I made a mistake when first looking at holcombs device, I assumed the rotating magnetic field was linked to a rotor, however the rotor does not spin so its not a rotor, which I guess was an assumption I jumped to because the design is clearly based on a synchronous motor.

@Cadman,cifita, if your trying to do electromagnetic FEA on Linux you can try FEAtool, new, haven't played with but it's free and integrates with Matlab, that or COMSOL.  Don't know what version of Linux you're running (I'm on Manjaro) but you could always run windows in a VM and push most of your cores to it for running simulations.  QEMU/libvirt is great, has a bit of a learning curve, but you can do a lot with it. My current rig is running Linux/Mac OS/Windows (concurrently) no problem and have built 2 other systems like that for my nephews.
Side note on this. A while back I posted in this thread regarding correlations I noticed between this and the 1908 Figuera device.  I haven't really gone in depth on this device but I believe it could work two ways (together), 1st is what I posted "heat", here's a link to JNL Labs for the 2SGen http://jnaudin.free.fr/2SGen/indexen.htm, if you scroll down to the bottom of the page there are three links under 'Interesting Documents to Read' related to this.  2nd which never occurred to me when working on my version of the Figuera device was that Holcomb must have added some open path into his closed magnetic circuit to collect energy from the environment.  It's most likely  just some physical section of his device where his excitation fields (budget) are allowed to pass thru (outside of the generating sections-budget) enhancing the total B field and collecting the excess on collapse/change (budgeted section) .

I've been reading and reviewing diagrams of that recent patent. I'm not sure Holcomb uses distinct magnetic circuits. Reason why I inquired about doing FEMM. Thanks SL, and others who commented, but now I know my "tools" are totally inadequate.

And, just kinda odd, latest version in patent shows no center shaft. Inner 'rotor' with inner & outer slots, stator, second 'rotor', and another stator. With some sort of bearing/bracket to rotate one of the members, for position tuning. Wonder if he'll see torque on it???

OT - F.Y.I. example: [Win10 stand alone - $280US complete]

Amazon - HP EliteDesk 800 G2 Business Desktop Intel Core i7 6700 3.4Ghz 32GB DDR4 RAM 1TB SSD Hard Drive Win10 Home (renewed).
Can take 64GB RAM. Nice machine - got them all over the lab (12+). Good for off-line as well.  Neuter Win10 for better experience.
More than adequate IMHO.  Networked, these beat the WorkStations and only about 30W each (Z80x WS is 1200W). These are well built!
$ 280.08 - Monday, Aug 15.
https://www.amazon.com/HP-EliteDesk-800-G2-Business/dp/B07XDCCP38/ref=sr_1_18?keywords=hp+elitedesk&qid=1660095147&sr=8-18 

Or this one, (not familiar with this type) Dell OptiPlex 9020 - same as above but older graphics [4600 vs 530 intel] - check specs carefully!
$247.00 - Amazon DDR3 RAM says it an older intel chip - they don't say what the i7 is.

And why did you decide that the larger the program, the more accurate it is?
Do you know exactly what the magnetic field looks like and how it works from the current of the phase laid in the groove?
Before something can be modeled in a problem solver, the program must be given the correct initial conditions for the solution.
Secondly, you need to know for sure that the algorithm for solving the set goal is correct.

For the formation of EMF, a stable rate of change of a constant and evenly changing magnetic induction is important.

That is, the formula E=BVL should be written as E=(B/dt)*V*L, where V (speed) must be a constant and L (conductor length) constant.

In this case, the speed in time also has a vector. The EMF generation process is more complicated than you might think.

For example, the program shows me one thing, as it contains a traditional mathematical algorithm, and the graph on the oscilloscope monitor is different (this is exactly what I saw).
And the most interesting thing that the oscillogram shows does not fit in with what the EMF formula declares in terms of the sign of the EMF itself.

If BVL results in E [V/m], then (B/dt)VL results in E/t, [V/ms]
