Cadman,

Before beefing-up the 30 Ton press I'm going to follow your lead re: "resin & iron powder mix."

May have considerable merit IMHO - for example, see the attached paper.

Quote from K - "Are you done yet, are you done yet?"  ;) Quote from SL - "Give it a rest!"  8)

Q.: If I thought for a second that this method didn't work, would I spend >$2800us on machines
to make and test laminations and substrates?

That’s what I want to avoid, expensive tooling.
I continue to experiment. I tried a cast with two 1-1/2” dia N42 neos under it to see how that would work. The iron was pulled down strongly and I thought Oh boy! Did a few other things while it set, came back and discovered a porcupine casting! :o Funny looking as hell.

Hi all,
You might consider this approach to getting useable cores for first attempt prototypes which I've used recently. I am just experimenting with behavior of "wires in grooves" as member rakarskiy would say, or coils in slots to satisfy my own interpretation of theory. My investigation is on going but indications so far don't surprise me. Anyway, for your consideration, I'll attach a photo of my fixture. Made from sawing and grinding an old MOT, uWave Oven Transformer. For a piece of scrape, it turned out pretty good in my opinion. It does not heat at all, coils do occasionally. A second portion of the core fits on top for the tests. Good luck.

Hello, nice booth. Personally, I have already gone through this in various forms.

Answer yourself one question: how do you get the necessary magnetic induction in a slot with an induction winding?

Thanks Rakarskiy,
I left another reply to your EF post.

On your first post there today you link to this which I hadn't noted before:
"A similar principle is implemented in the patent  of the inventor Park Jae-sung  " A device for generating electricity using a DC source brush that rotates with a field pole generator, a device for generating a DC source US8629588B2 "
Very similar to Holcomb in the primary, or field, winding scheme that I find disturbing. I've eluded to it several times. It does involve your wires in grooves. I am using the test fixture to double check my comprehension of Ampere's Law and related theory. It's served me well for decades. But doesn't hurt to witness it again. There is more which I intend to test, but as mentioned, so far, nothing weird happened. I still have yet to understand your problem with winding in slots. Been working great for a couple hundred years, when done correctly. I intend to post more information about it. If you see something you would like me to try, I'll consider.

BTW, a while back, you showed a 'miniture' replica of the HES device in the build process. Did it complete and test? Care to share?

Cadman,

Agree - but it appears pretty much any form of usable SMC requires some level of compaction.

So far I have not found many SMC formulations with modest compaction (a few hundred MPa),
but there is light at the tunnel hopefully, as shown in the article attached earlier. Quote:

"Conclusions[/font]
Magnetic composites based on bulk amorphous alloys on an iron basis are used in many branches of electronics and[/font]
electrical engineering. This work shows that it is possible to produce these types of materials using a simple uniaxial[/font]press and a relatively low compression pressure. It is worth adding that the composites were made with only a small[/font]
proportion of non-magnetic binder. Composites were made of alloys differing significantly in the coercive field value.[/font]
However, the properties of the composites themselves are very similar. This is due to the separation of magnetic powder[/font]
particles with a non-magnetic binder. This separation weakens exchange interactions, magnetic properties are[/font]
determined by the arrangement of magnetic particles, their size and degree of separation."
[/font]
[/font]From the text: "[/font]The material was pressed under a pressure of 25 MPa for 30 minutes."
[/font] [25 MPa ~ 1.82 Ton]
[/font]

Anyway, if it doesn't work, the resale value of the Press is quite good - at the local Merry Jane outlets!  [/font] :P   

Plus, it might have some irony - "MJ Press Solves the Energy Crisis!" How Ironic would that be?  :)

Hello! Unfortunately, I have no more information about the Holcomb patent minigenerator. The guy came to me to clarify the details, I voiced my vision and explained it to him. As for the function of the groove in the stator, I describe everything in detail in the book. I did not expect such a turn.

Hi Rakarskiy,

Any update on the Book release yet, and the price? Would like to add it to the course.
(several dozen copies minimum at this point - and these are corporates so their not stingy!)

Best regards,

SL

Here's the paper again for the B-H Curves above:

The inner rotor of suitable size was found. It was placed into stator 1.1 kW  And nothing again.
Barely lights a light small bulb. What should I do, then ...

But an increase in the exit was discovered if one the output winding(probably both can)
falls into resonance.  It was a single -phase motor with a phase shift capacitor.
It was soldered on the conclusions of the engine, and an effect accidentally discovered. :)

Do the members have the same pole count?

Not. stator have 36,rotor 24.

p.s. And I'm also wondering if this will work as a frequency multiplier?
If the number of poles is different.  I'll try to measure it tomorrow. :)

36, 24 sounds like # of teeth (or slots), not magnetic poles, which are typically 2-pole, 4-pole, 6, but seldom much if any higher on that size. The point is, running, for example, a 2-pole member with a 4-pole member may cancel induction between the two. It's easy to tell pole count if the machine used a salient pole field, like 2 or 4 PMs. If it is a distributed wound machine, like induction motor, you can determine the coil pitch (radial distance between coil sides).

I have understood now. I think that the number of poles can definit from that, motor have 1380 rpm. on 50 hz. 
And the little motor have one phase, 50hz. and 800 rpm.   
The output frequency does not increase or decrease compared to the input.
Only when the rotor is rotated inside by hand, does the phase change relative to the stator current.

Have you inserted the motor stator into the motor stator and wanted to start the system?
See the hint, you need to simulate the operation of a permanent magnet magnetic rotor. Where did you see a permanent magnet working on a sinusoid?
The second clue in the generator is the magnetic field from the phase current and the magnetic field of the rotor must be summed up, it is this moment that forms the electromagnetic braking force.
I already wrote here that a good motor is a useless generator, and a good generator is a useless engine.

Yes, I want it very much.

Why my copper foil or pipe  placed into stator with current. And my pipe isn't making short circuit for stator's windings ?
The foil should create one short-circuited turn for the stator windings.
But however this copper foil placing between stator and my yesterday rotor decreased its induction a bit.
