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

[Craigy]

I have a hunch that our friends at Steorn have the same or very similar idea, shame if we got there first though..

The shield used in the video is 2mm thick and oddly shaped, i have shield that is up to 4mm thick, but you have to use what you can find. I have emailed a few hard disk manufacturers asking about that shield material, so  perhaps one might answer. If i knew what it was called i might be able to find out more about it, but doing searches to try and find info on hard disk drive shielding etc brings up nothing of any use.

Just saw allcanadian's post "Bingo" ..we should at least get the torbay working with shield's then gentlemen..LOL

Uh Ohh what did I do now?
I just had a thought, that maybe It might help to post things I know work, that I have tested. That work pretty neat, so here goes nothing. In picture(1) there are two mags in repulsion with a thin metal shield between them. Here's whats intersesting-
- the shield works even if its 1/16th inch on N38 neos, works better if thin
- the shield must be exactly centered between mags
- Move both mags equally in or out until there is no repulsion between them with shield centered
- the shield moves freely until it's edge passes the end of the magnet, then its attracted back towards the mags(so what if you used springs to pull on the shield balancing the attractive force?)
there would be no pull back and the shield would move freely.

Picture(2)
A magnet pulling on a hinged flat metal bar
- The magnetic force of attraction gets stronger the closer the bar get's
- the first spring on left holds bar up with constant pressure(linear)
- the second spring has a square wire loop and pin so it does not pull on the bar until it moves so far down, this is called a loss of motion mechanism.
- the third spring is the same as second, So as the bar moves down in attraction the spring forces exactly match the magnetic forces, so the metal bar has neutral forces and moves freely.This is the primary mechanism in the wesley gary generator which nobody seems to care about.

Picture(3)
Rotary LEMA
I proved the LEMA process with this machine.
- the grey shield is a "C" section metal shield 1/8th inch thick free to rotate on a center shaft.
- three 1" round by 1/2" thick N38 neo magnets placed on round washer 3/8th inch apart with shield free to rotate around washer.
- Shield roughly covers only two magnets at a time designated by black lines.
- shield will move with basically no force between magnets, uncovering end magnet at each end.
- When shield passes end magnet it is attracted back, I see endless applications for this little device, if the whole washer was covered with equally spaced magnets?

Anyways these are my top picks for now, It is weird that so many people read so many things into Wesley Gary's machines. When in his patents he tells you roughly how it works, but in a cryptic kind of way. Basically his neutral line with one magnet is bogus, I tried hundreds of combinations, But with two magnets in repulsion and a spring balanced shield it's a piece of cake. Try it you will like it.

Hi all canadian,

Very interesting, what types of metal shielding did you experiment with? Was it just standard steel?
In my experiment on video the shield i place over the stator magnet does not have the magnets from the rotor directly opposite.

Now, it is not opposite the rotor magnets, so when introducing the shield there is a lot of attraction to the stator which is not a bad thing in this instance. Since we need to cover the stator to provoke movement. BUT when movement is under way i conclude that the force required to remove the shield will be very reduced because it would now be in Balance ( at least some of the time) against the Rotor magnets, as you have explained in your previous post.
I can't wait to get my hands on some linear bearings, so will try and knock up a quick and dirty alternative this weekend which should keep me experimenting until the Bearings arrive from the states.

Thus i hope that we will end up with 2 avenues of investigation. The first is that if the shield is well balanced we can move it electrically using a "Clanzer" type device that discarges energy gained to move said shield Or the Second is that we could get a torbay hybrid which has lots of torque, to move the shields up and down via a cam. Again since shields would be balanced , effort required to move them would be much less than if we were trying to raise/ lower stators.

Something must be wrong here....It seems too good to be true!

Well Caps and Diodes arrived today, so quickly knocked up a bridge rectifier with the 4 diodes and put the 16Volt 10,000 uf cap in place.

Span the wheel up and watched the voltage/charge int he Cap creep up slowly.

Had a small 5 volt solenoid attached to the other end of the Cap with a push button attached, so when the voltage was upto 5volts, pressed the button and yep sure enough there was enough power to move the solenoid arm a good 10mm unloaded. Using my fingers I could not stop it's arm being pulled in, so plenty of power in the little devil to lift either shielding out the way or move a magnet.

Not impressed though, takes alot of rotations on the small 8 inch wheel using 4 magnets and the coil to charge that Cap up enough.

So next went back to a 8 wire Stepper motor and put all 4 coils of the stepper in series, put this on the cap and diode combination and the voltage shot upto 5 volts on just a couple of revolutions by hand, very impressed.
I reckon it Needs abit more torque than the little wheel can deliver, but now very tempted to mill out say a 24 inch wheel or used a bicyle wheel and attach the wheel directly to the stepper motor.

Will attach the small wheel and try over the next day to see how many revolutions it takes to get to get the power stored and go from there. I also have some 6 wire stepeprs than turn alot more easy than the 8 wire ones, so will wire these up and experiement.

I am thinking along the lines of more lifting the Craigy shield rather than moving a magnet, as this can be done in mind every couple of revolutions, which in return will apply the magnet back to full repulsion for the next spin.

@allcanadian nice pictures mate and well done.

Regards

Sean.

Hi Clanzer,

Just a thought, what about using the stepper motor as the bearing on a takahashi magnetic motor? Smaller but maybe less work to knock up?
