Now have a nice stainless steel shield installed and what i noticed above is still valid although it self centres regardless of how the magnets are installed. BUT , the force required to move the shield away from the magnets seems less when the actuator has like poles facing upwards.

Was the shield stainless previously?

Hi there,

no i was using a bit of ali to mount things on, one cent coins and the like. I now have stainless steel
Anyway there was a flaw in my replication, i'm not too proud to say..The magnets when placed directly in contact with the steel linear bearing effectively combine to form a horse shoe magnet thus cancelling all flux acting on the bearing itself.
What i did, was to make a nice brass plate with magnet holders on it..(Yes a bit of a plonker i know) thus the magnets were attracting the runner to the center. This was easy to fix, i just dilled holes through the brass plate so that the magnets are in contact with the steel. Now i can test the thing

Still, who wants to patent a self centering device LOL....

Nice video Craigy,
would be nice to see it set up with a solonoid triggered by your motor disc.

Well blatantly forced ,to work,

what came to my mind is,can you get a mechanism to automaticly pull that slider back and forth which is driven when it turns???

so that it actually keeps spinning?

I Am, thinking about this with that video, >>>  http://en.wikipedia.org/wiki/Steam_engine  .

so that it keeps on spinning,and if it gets faster then the slider moves faster,in rhythm with it spinning.

WIth out you haveing actually to be there,hey i think that will likely to work, then you have a self running device.

how hard was the flux force,when you pull that slider back and forth?

The possible bottlenecks would be the slider,


well there are my thoughts,that came up when i saw the video,

or a nother way, Electric driveing to slide that instead of hands, like pulseing,and you can have sensors which tell it when to move when it has almost completed it's circle,so its in near enough time to slide and keep it going like when it spins and when the sensors activate when they come into contact the electric motor slides it into place to keep it moveing (?)




hey you saw the video did you?

well theres my thoughts,although i do not have enough understanding on electric but for someone like me who was not taught on that, those are my thoughts to get it more nearer to ''self running''.

@craigy

is there any growing with low energy actuator?
you moved magnets in video. why do not you move the shield? and why do not you hold it up vertical?

Hi There, I could move the shield, or the magnets, but as the patent has the magnets on the rail and not on the carriage i copied the patent . Sorry i forgot to hold it up vertical, it will fall under its own wieght, but these are easy to make, try for yourself , i'm not trying to hide anything..LOL

thanks for reply.

i dont have mechanical equipments. i try to buy magnets. i dont speak english very well, so youtube videos are understandable.

thanks again for your sharing ;)

Craigy,

Nice videos. Are you going to go any further on this? I would think that this could be setup with maybe four of the shields and use ramps to move the shields. Sort of torbay style.
Also, the video shows that your magnets are sticking to the stainless. Magnets do not stick to stainless steel. Maybe that's why you got it so cheap  ;D

There are different grades i assume, i know my stainless steel nuts and bolts don't attract whilst the spoon , the sink and the pressure cooker do to varing degrees some more than others and they all perport to be stainless. But in the shield that is not so much of a problem as the forces are equaled out so that the magnets of shield can move freely. In fact it is more the magnetic permiability properties we are after, ie, that the shield does not get magnetised overnight that is most important..

i have lots of projects half built at the mo.. so not sure when i will return to the shield, i built another using 3 x 15mm round magnets, now they are strong, and the shield or magnets can fall down under their own weight.  So it works, you saw how attractive the errm, stainless i was working with is. lol..

i was thinking of building a revised torbay, with just 3 stators or lemas, to see if that would work.

still so many things happening , what with steorn and others, not sure what project to finish next..

I think the actuator is older steorn technology - if a year or so can be considered old. I listened to an interview with the Steorn CEO and he said he had a self running machine and it worked with magnets pulling on ferrous metal. This interview was found on the Steorn website.

Craigy, like iadcw I noticed Steorn said they had pmagents working on ferrous metal.  That's the approach I tried, because I didn't want the shield to interact with magnets on both sides.  If you use a shield that strongly interacts with the magnet and put it as close as possible without touching (like in the LEMA patent) then you can turn off the magnet and expose it's full potential when you turn it on (because the magnetic field decreases so quickly with distance).  Then of course the problem is moving the shield because it wants to stay right on top of the magnet.  I hooked up a crude mechanism that used an elastic band to balance the shield's desire to be over the magnet.  I got very close to equilibrium where it took very low energy to move the shield.  Since the shield was reactive with the PM it meant you could basically touch the ferrous metal to the outside of the shield and there was very little attraction (almost perfectly turned off).

Yes i see, you are countering the attraction force with a spring force, but that is not a low energy actuator in the true sense of the expression. In your diagram if you add another 2 neos either side of the one there at the moment you will find that the shield will not be attracted to just one of the neos, it will move freely over and between them, until the shield gets to the extreme end of one side or the other.

The neos should be placed on a metal plate with all of the same poles facing upward, the shield will require little or no force to move from end to end
