Solid State Orbo System

[Jimboot]

Thought I'd take a shot at this too. My Ossie motor is going well at 1mw & 1000 rpms & I need another challenge. Which page has the best setup so far in this thread?

Good Evening All,

I have concluded the building of my pulse kit tonight.  It really wasn't that bad at all.  I had purchased a small battery powered soldering gun, because it has a nice thin tip.  It works so, so.  I have a radio shack soldering gun that heats up well, but no small, thin tip available for it.  I will have to invest in a decent soldering gun, with proper tips, in the future.  I see how having the right tools for the job is so important.

I am out of town for the holidays but will return next week, and then test out my pulser and see how it goes...

Happy Ressurection Holiday to all!   

Cheers,

Bruce

Good Evening All,

From the Steorn page, my guess would be you get a metglas or nanoperm core with as square a loop as you can find (totally nonlinear), wrap it with a ton of thin thin wire for good inductance, then you hit the coil with a short pulse clockwise through the circuit and immediately follow that with a longer, higher powered pulse counter-clockwise through the circuit (so to speak), so you build a north magnetic field and then a bigger south magnetic field, to simulate the effect of the rotor passing by the angled magnet in the PM orbo configuration. And that same massive coil around the core collects the excess rebound from the ferrite core? But how do you fire and collect from the same coil?

The domains in these square loop coils seem to have no "entropic" state. It's like they're all aligned and flip like a switch to the opposite orientation...

I've never handled a square loop ferrite. Do they physically feel different in the presence of a magnet?

No, a Metglas Square loop does not feel different in the presence of a magnet. 

My pulser is to pulse at different frequencies, my SSG3, you can read about, further back, if interested.

Just a few thoughts on the Steorn solid state orbo....

To me it looks like Steorn has three coils around a ferrite cylinder with a bias magnet in the middle. They probably have an external asymmetrical magnet on the outside. I could be wrong about the magnet placement... ie the asymmetrical magnet on the inside, and bias on the outside. I think they are using the three coils to perform heterodyne frequency multiplication with the non linear part of the M-H curve of the ferrite. Two coils input the two low frequencies, the third picks up the multiplied high frequency.

See the link below... specifically the 'mixer' section.

I'm just piecing this together at this point... brain storming. Does anyone here have any heterodyne experience that can shed anymore light on this? Does this sound correct? Any other possibilities?
