STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

Maybe the following is a better way than epoxying the wood to the harddrive discs. The hardrive has two metal discs, so how about cutting two pieces of wood (one for each side of the harddrive disc), then cut two thin slots into the wood so that the wood slips into the harddrives dual metal discs. Then wrap some metal wire around the entire disc, thus securing both wooden pieces. That way I can always remove the wood in case different size magnets are needed, or whatever. Also this avoids the 24 wait for the glue to dry.

@PaulLowrance,

If you use Plywood and drill holes for the magnets AND then glue with Epoxy,
then the magnets will stay on the rotor at high rpm. It is no problem to
mount the coils above the magnets. If you have round magnets then the
drill method is the best way to do it.

Hi to all,

I just watch at yours work since Steorn last presentation. I think you are doing grate job, and I hope that this project will succeed!
I want to point on Steorn patent:

http://www.overunity.com/index.php?topic=8411.msg218173#msg218173

I think it explains how orbo works, and how it should be optimized to work most efficient. Charts are self explanatory, and you can learn a lot. The main thing is that magnetic interactions in static system - due to the so called "magnetic viscosity" - are different than dynamic. According to patent when you increase relative speed between core and magnet, the core saturation is lagged in time and therefore its value decreased. While torque doesn't change as fast as saturation change (saturation decrease for about 100 times, but torque only 2). I wont explain every thing, you all have to read this. It is better explained there. Correct me if am wrong about this.

All the best!!!

Hi marek,

Thanks for that important info! I just knew it, that it was due to magnetic viscosity. Since you studied the Steorn patent already, what type of magnetic core do you recommend?

[PaulLowrance]

I just took a look at the Steorn patent, and am amazed that it's all there, like marek said. They show everything from tons of magnetic viscosity plots to the design and theory. Steorn is legit!
