Sorry a bit off topic...

you made the following remark...
QuoteKnow-how to turn the iron powder into laminates.

I was looking to create a pure magnetic motor that requires a moderate/high permeability, low conductivity steel rotor. I was thinking of using a simple resin-iron powder mix in a mold.

What you said tweaked my interest, are you able to provide links to the technique you are suggesting it may assist me in my endeavours

It's buried somewhere early on in the HES thread, but basically I stated using a clock chip,
a shift register chip, four half bridge drivers and a bipolar power source.  As simple as it
can get.  Wire it up, turn it on, and let'r run.  Let me dig a little and see if I can find my
post.

That's certainly far less expensive than a PLC! I've downloaded the datasheets for the flip-flop and the counter and I'm studying the circuit.

I have some questions about it but I'm short on time, so if you don't mind answering them I'll post them as soon as I can.

Thanks again.

I assume we have 3 criteria's:

1. 3 phase preferably
2. Like polarities opposite from each other as the holcolmb image
3. And even pole number so we can properly alternate polarities without having 2 polarities next to each other.

Then I think the only configuration that works with a 36 pole stator is 3 coils in series per pole.  12 poles.
Then 4 poles would connect together per phase. 

If we want to do opposite poles across from each other- there is other options.  I just don't understand all the dynamics yet..

On a side note- Cadman- when you get time-can you explain the pickup part as you envision it?  I have been reading the Holcolmb thread somewhat,  but so many ideas and predictions have been pitched I would like to hear your breakdown and plan.

floodrod,

I think you laid that out nicely.
I have hopes of ending up with a 3 phase or maybe even a 6 phase, eventually. But since this all a shot in the dark at this point I'm leaning toward the 32 coil setup I last posted. Why? Because it would be the quickest way to see if the rolling fields will be viable for producing a decent output. Also it will keep the costs to a bare minimum since it would only need 4 outputs to the rotor coils. You know, start small and work our way up.

There is plenty of room in the interior of the stator to place a proto-board with 36 wire terminal pairs on it. That way the coils could be connected and reconnected to come up with any configuration imaginable.

On a different note....
The stator I have is wound with aluminum wire so once the existing coil connections are cut there's no going back to a rotating generator. If this project gets off the ground, which is looking more and more likely, I'll get another stator to modify.

QuoteOn a side note- Cadman- when you get time-can you explain the pickup part as you envision it?
I'm sorry, I don't understand what you you mean by 'the pickup part'. Can you clarify that please?
I'll be happy to try to explain anything can.

The permeability of the polymer bonded powdered iron is inferior to electrical steels. And it's nothing at all like a powdered ferrite that has been bonded and sintered.
The main reason I use it is because it's almost pure soft iron.

That being said, the technique is my own. It's just the powder poured into a mold, the polymer added, and then it's compressed with a weight until it's dry. Heating it to 200F in an old counter top oven for 30 minutes (depends on the thickness) with the weight on it will cure the polymer.

Gotcha...

Regarding the pickup-coil question, I guess I don't understand the concept fully.  I thought this was similar to Pierre's build of rotating magnetic fields.  And in his, I see what appears to be a pickup coil right in the center of the stator. I assumed the rotating magnetic fields get amplified by the core steel / iron and inducts a pickup coil in some manner.

I guess his build is completely different.  I will need to read more on it to grasp the concept before I can be of any help here.
