Steorn Magnetic Toy

[Craigy]

From what i have read over at the steorn site they showed a few toys to prove at least some of the principles being used. Now there are quite a few designs, the one displayed at kinetika had 2 disks perpendicular to raise lower wieghts , and other models that seem to have odd counter wieghts on the shaft. Here is my latest effort. It displays what looks like 100 percent energy return, but that cannot be right, look at the photos and video and tell me what you think, its a nice coffee table toy at least..lol

Hi Craigy and All,

Your link works, thanks.

Watching the linear movement of your 'stator'   it occures to me if it could be controlled by the armature of a relay? Because i think the needed useful distance to cover is a maximum of +/- 2 or 3mm which is already enough to pass the rotor (with the two magnets on it) over.  And I think of the extended arm of the armature of a polarized electromagnet. See this link for a polarized electromagnet:
http://www.atcaonline.com/coinrelay.html 
Polarized electromagnets have the advantage of using less current than normal ones because they include a permanent magnet and are very suitable for pulse mode operation, and can have much quicker switch on or off time than normal ones. Of course you cannot expect several thousand RPM from this setup either but this isn't the goal right now, is it.
The armature of this electromagnet could be extended with an orthogonal arm fixed to its middle and the other end of this arm would be fixed to the center of your linear stator, that is how I think. Other solutions are certainly possible.
The control of this electromagnet then could be excited first with a few volts of 50/60Hz AC voltage simply taken from the secundary of a mains transformer as a start and in this case the armature  --together with the linear stator fixed to it--  would oscillate at the mains frequency in your present setup, the amplitude of the oscillation being the +/- 2 or 3mm needed to pass the rotor over the sticky spot. (The sticky spot would always be in the middle plane of rotating magnets facing the center of the magnet placed on the linear stator and these two planes are to be shifted to the left or the the right by 2 or max 3mm).

If this is not practical, then your linear stator could be included like a piston into a polarirized electromagnet, could become the moving armature of it. This solution needs further thinking of course.

I hope what I wrote are understandable

Hi!

I have been playing with magnets since (for?)  a long time.
Applying some ('tangential' or 'longitudinal') magnetic force (with a magnet) to a wheel equiped with magnets is an idea that comes quickly in mind.

Please have a look at : www.freenrg.info/Minato
Specially at www.freenrg.info/Minato/Minato_First_Motor.wmv

@Craigy:  Is it not similar to your device?
The question is: how can I do it automatically.
Sounds like that Steorn and Minato succeded.
Best
