Actually, those aren't patents, they are patent *applications*. You can apply for a patent for anything, but that doesn't mean you get it.
Posted By: alsetalokinAs with many energy problems, looking at this from the standpoint of balance is probably helpful.Posted By: QuantenQUestion , what difference would it do for the work function of the motor, if instead of having :
-> a ferrite core around on stator atracting possibly magnet on the rotor when current is off, but being shioelded when current is on
-> same PM magnet on rotor, but on stator a magnet which is off when no current , and on with the same attraction / B vector felt by the magnet when the curernt is on
If the case below is more easily modellable or known, then gut feeling for me is that there would be no difference in the final outcome, except that instead of switching off the stator you switch it on.
The difference is in that CEMF thing. Also in the first case, the Orbo case, the rotor gets thrust only when the coil is OFF so it's harder to track the energy flow and easier to be garden-pathed into starry-eyed oblivion. It's almost got me sucked in, and I haven't even been misedutained.

Posted By: couldbePosted By: alsetalokinI have believed all this time that Steorn had nothing interesting, much less revolutionary, and that their mistake, if it was one, was a simple one. I think otherwise now. I still think they have nothing revolutionary, but at least they have something moderately interestingElectro-magnets have been around, what, 150 years or more? They have been studied, I thought, to a fare-thee-well; yet even an adept such as yourself is surprised by the results of a very simple experiment.
Is it reasonable for civilians like me to think that the properties of magnets are far from being known completely, despite what has been said on these forums in the past?
And if you could nearly eliminate cemf so easily, is it possible that Sean was right when he claims that, with care, it can be eliminated completely?
Posted By: couldbeFaraday's Law has not been repealed. Steorn have shown no evidence of repeal. They have shown that you can garden path people by obscuring small quantities beneath much larger ones.Posted By: alsetalokinI have believed all this time that Steorn had nothing interesting, much less revolutionary, and that their mistake, if it was one, was a simple one.

Posted By: timetrumpetPosted By: alsetalokinI guess this is as good a place as any to say this:
I have believed all this time that Steorn had nothing interesting, much less revolutionary, and that their mistake, if it was one, was a simple one. I think otherwise now. I still think they have nothing revolutionary, but at least they have something moderately interesting, and I'll bet there is a run on ferrite toroids right now. And their mistake is slightly less simple.
Anybody know the exact ferrite used by the lads?
I don't think that's been revealed anywhere IIRC, just general terms.
Two things:
1) Can you consider unblocking me (as "ingliss") from your Youtube channel? I'm not interested in any personality issues, so I'd like to think that lot could be put to one side. I don't intend to be posting replies or comment on anything other than whatever the video may be FWIW.
2) You've stated recently that the rig turned CW and then CCW. I don't think this is correct.
Sean Mc, certainly confused matters by saying this during the demo. I asked if he'd misspoke and he confirmed this; he meant to say "CW" both times.
I've confirmed this by running the video through VLC at (I think) 1 / 5 speed. CW both times.
Edit: erroneous "Steorn" (I set em up...)

Somebody correct me, but I think that Al is more astounded at the cleverness of the arangement, rather than a new property of the magnet. Unless I missed something, it seems that it is known that when current go through toroid magnet at saturation they emit next to no field. The cleverness is here to use the atraction of the ferite when it is off, the non-atraction when it is on. But tehre is really no new law, nothing which break previous knowledge.

Posted By: duncan torusand yet the toroids are supposedly irrelevant according to Sean, what's that all about?
Posted By: duncan torusso far it's looking like an electro-smot.
Posted By: alsetalokinThe toroids make it possible to claim that the coil's field isn't directly driving the rotation of the motor, since "everyone knows" that the field of a toroidal coil is confined within the core.
So, what is the efficiency estimate for Orbo? Is it really 300%, like Sean claims? Or it is more like 3%?It'd be real easy to tell if Sean allowed someone to "take (an appropriate) set of meters to it."
Just asking.

But what is driving the motor?

But what is driving the motor?
Magnetic "energy"!
But what is driving the motor?Just offhand, I'd say what drives the motor is an Ansmann 10 amp hour storage battery, regularly recharged when Orbo goes "off line". Or did you think that's done because of bearings overheating? As someone noted somehwere "Reed switches are the new bearings!"
Magnetic "energy"!
