Any one tried to use Adams idea to get over sticky spot?

Darn Mother in laws hehehe, do they not realise we trying to save the world here? LOL 

Can see what you are saying about using attraction to accelerate through the sticky point, so are you leaning towards having the shield being attracted to the rotating magnets as the sticky point comes around rather that using the shield towards the static magnets to displace the field?

I did try this in a round a bout way on one of my spiral wheels, by simply changing the first two magnets to face South outwards and left the rest of the spiral of magnets with North facing out, but the attraction was enough to stop the wheel dead when it cam around. Now using some sort of shield that would be there briefly to add the attraction and then remove it at the right time could work.

Hi Clanzer, its going to be one of those weekends when the mother in law comes around and i can't complete what i so desperately want to complete.
So far i have started to test other materials as "Shields" although i don't like that word, i think standard steel will do the job i want. The Shields from the harddrives were used to test the concept, since if that material didn't work then nothing would probably work.

Let me elaborate on my theory of why attraction is not a bad thing, when using a repulsion motor.
We all know that when you get to the end of the track the rotor bounces off of the sticky spot.
Assuming the the rotor is made up of many magnets the ones on the leading edge are the ones that encounter the sticky spot. The ones behind are all happily following on behind and as far as they are concerned they are still following the down hill gradient in flux. Like water down a water fall.
Now at the end of the line, or last bit of track or last repelling magnet we encounter the "Wall" that begins to brake the magnet and finally bounce it back the way it came.
If that braking force is 100% of the kinetic energy obtained in  the run up to the sticky spot then if we reduce the braking by 10% we would get Rotation! i.e. Flashing a bit of leg ..er i mean steel at the rotor would produce moments of attraction which in turn would reduce the braking efficiency

The Law of Magnetics according to Craigy , This was a thought experiment.

But i like it LOL

Hi all,

After many experiments and construction i have discovered a small fault in my shields.In the photo above i was using a chunk of harddisk shielding, i then went about making up 4 shields out of steel.
My concept is valid i believe but i have now got rid of all of the steel. the idea works if you only have one shield ,and the rotor is under magnetic tension. But when you add more and more shields the steel is upsetting the flux to much. Reducing the effect and it produces sticky spots in areas that didin't have sticky spots LOL. I had made the shield or "Attractors" about 100 times too big.
I have now changed the shields for ali, so that i can still use the guides that i made for the steel ones. These ali plates or shields move up and down just as the others made of steel. but with one small difference...

To be continued

Hi Clanzer and All

I emailed Western Digital about hard disk drive shielding and this was the their reply to the question what is it?:

aluminum substrate, coated with a magnetic surface manufactured by Komag, Fuji, or Showa.

Well something for google,

Cheers

Hi Craigy

I think they are on about the Platters not the shield

Pop in Google aluminum substrate + Hard Drives.

I was thinking about the adams motor "again" and had an interesting thought. Take a horseshoe magnet and inbetween the poles put a DC motor armature, now the motor should turn when power is applied to the armature- it will attract and replel the PM field. The motor could be made very efficient with a pulsing input, maybe 90 percent if done right-- so it would be near unity 100 percent.
Here is where it gets weird, when the armature is in attraction the whole PM field travels through it, in repulsion none of the PM field travels through the armature--so what happens if the DC motor armature in repulsion was also used to switch the PM field to another coil nearby as in my picture. The armature is still repelled but the PM field is also redirected completely to the external coil, so if the DC armature work out is equal to the electrical input to the armature then the second coil output must drive it to 100 percent or better effeiciency.
Better yet, what happens when the DC armature has no load attached? thus can do no work.- and armature output is based on electrical input remember?
Very strange indeed.
