Holcomb Energy Systems:Breakthrough technology to the world

[Beginners Mind]

Thanks for the clrification,  Milling sounds like an easier route than building a laminated rotor / stator. I thought reluctance & permeability may have been an issue. I've looked at 3D printing in iron then sintering. I'm even considering steel shot in epoxy but I'm still hunting for a more suitable rotor for my existing gen stator.

@Jimboot - If you decide on laminations:  I've used http://www.polarislaserlaminations.com/ for making custom generator cores on numerous occasions and can vouch for their exceptional quality and precise dimensions.  You email them a 2D .dxf file of the lamination outline, pick your lamination material from their supply, tell them you want the laminations stacked and bonded to your specified thickness.  There are tips on their website for how to go about it all and they are very helpful with email replies.  M19 and other electrical steels are in stock.  They give you a solid quote before starting a job.  Single piece prototypes are AOK.  Other companies do the same, of course. 

On another note, are you pursuing a build of Holcomb's current, 2-stator, all AC design, or their prior, sequentially pulsed DC design?

Thanks BM. I'll try and find someone locally a lot of the laser cutters I've spoken with so far do not know what transformer/silicon/electrical steel is. I like the idea a lot - I may have to end up buying a laser cutter and sheets of steel myself at this rate

I don't understand why the machine takes so long to count? I encountered such a problem, but it turned out that the conditions for calculating the initial data for the machine were incorrectly set. Sometimes it's worth breaking the calculation into parts.
My advice is, first you need to master the design element, and only then the whole design on a special software product.

As for the cutting of special electrical steel, you need to look for specialized companies. Perhaps they do not want to do this, they are unprofitable for a small order of an unformatted task, or they will deliver a sky-high counter.
Electrical steel is too brittle. Waterjet cutting is very suitable for this purpose, it does not overheat a thin sheet that can be deformed during laser cutting.

By the time the G-Code for milling and
winding reaches the CNC fab shop

Bunch of  grownups experienced  problems,
A need to shine is so important.  for some of this topic participants .
Loud laughing  in front of the screen of my computer
made me  go this morning first to mechanical shop.

What?

" -Some guy talks about delivery of G code."
I started to laugh too.

- "Is he milling or winding or he doesn't know.?" .............................
- "what is he winding the core or the core winding? "


G code is not delivered  it is written for particular CNC and its operation.
But most of it for particular operation, is simply generated by  CNC and its computer.
You  are not waiting  for G code delivery...

Yes you may  directly generate G code based on CAD form external computer but it still
goes to the same CNC and it is written  specially with respect to this particular CNC.
What for.
In my lab all machines are network connected.
it belongs to CNC and is part of CNC operation.


Material traditionally used for transformer is not machined but cut by stamping press
because of this material properties.

Electrical Steel - is just general description, not used by professionals as important is the  given composition of it,
serving particular application.

Dear Solarlab
There is nothing wrong with not knowing something - called lack of education in given area.
I  started  my own mechanical shop as part of the lab 10 years ago too.
- having 20+ years experience in machining, mechanics, and processing.

It is not a shame to do not know.
I learn  every day too.

But that need of an individual to shine, to show how smart , how good,  how experienced he is
- is making my guys laugh.
Just take it easy,
-schoolboy,  at some age is being ask  to  grow up..

Wow stivep, what the hell is wrong with you, making an off topic 100% troll post like that? In all the years I have read your posts, you never acted like that.

I'm starting to think maybe you are not the real stivep!
