Hi all,

Well as i promised, this is a crude video of me using shielding to move a torbay rotor. For the sceptics out there i understand that doing things with my hand is not ideal, but i have 4 one inch linear bearings on order from the states which i hope will prove beyond a resonable doubt that the idea is valid. Anyway, i hope this will create some interest, Enjoy!!!

Hi Clanzer,

Since i am using the torbay configuration or rotor and stator there are 4 stator magnets keeping the rotor locked, when we place the shielding between one of the rotors and stators as per video, the machine behaves as if the stator was lifted, i.e rotor moves aided by the repelling forces of the other 3 fixed stators.

The actual force on the shield is difficult to judge, ( when i get linear bearings i will be able to mesure it) but is a lot less than the energy required to push a stator down. the stator seems to attract the shielding more i think. As i said, need to fix the shields well to give an honest opinion.

Also shield does not need to completely cover the stator, as you say , affecting the field by 10 % is enough to get movement..

Hey guys
I have built both of wesley gary's machines and there is a neutral line, but it only appears when a flat piece of metal is placed between two magnets in repulsion. It relies completely on the distance between the magnets, strength of magnets and size of shield- get it all right and the shield is totally neutral. What few people realize is that in both machines wesley gary made he balanced the forces with springs. What happens when an attractive force is completely counterbalanced with spring forces? The magnet can be moved freely inward and outward with little energy--and it's a very,very hard to do trust me- because the attractive force is nonlinear.

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.

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.

Sean.

Hi allcanadian and All,

I would like to add Ben Thomas and my own understandings on Gary's neutral line concept. I made some tests in 2003 when I first saw Ben's home page on his ongoing experiments. Earlier I read Gary's Canadian patent and as I understood, he suggested the best effect is with HORSESHOE magnets (though he left open the possibility of using other shapes of magnets.)   So I tested the neutral line' existance with a horseshoe magnet and with a rectangular piece of 20mm x 45mm, 3mm thick ferrite block. I did not make photos then from my work, but saved Ben's photos from his site and attached here. (His site does not exist now.)

In his first picture you can see the iron block placed exactly onto the neutral zone (Ben named it NZS line) and his Hall probe shows zero flux density (practically 0 Volt). This means that the iron does not show any magnetism received from the very near horseshoe!

In his second picture he moved the iron piece a bit above the NZS line (further away from the magnet) and the meter shows -0.131V , indicating a pole appeared on the iron piece.

And in his third picture he moved the iron piece below the NZS line (nearer to the horseshoe) and the meter shows +0.245V, indicating the appearance of the opposite pole on the same iron piece ending.

So the point is that easier to use horseshoe magnet to receive the neutral line than differently shaped magnets as you experienced.

Thanks for your ideas, especially the rotary LEMA, I like it. If you fill up the space on the rim of the washer with further magnets, you will get a symmetrical setup (in which the shield is supposed to rotate very easily) and you have to find clever ways to disturb the symmetry with the least amount of outside work. (Igor Knitel in this Forum showed similar shield-rotated setup with big ring magnets).

Hi Craig

I had a look at the Takahashi /Wankel engine a while back. Still trying to suss out what is actually attached to the electromagnet that moves when the rotor hit top center.

I do not really see how it will get over the sticky point force.

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?

Craig

Hi Clanzer and all.

as i understood it in the wankel, the electro magnet was just fired at top dead centre to push the rotor over the sticky spot, no mechanical movement as such. But having said that, look at the thread " Servo assisted magnetic motor, there is a nice video Jose did of his machine. In it he uses a modified servo motor to wiggle the top dead centre magnet and gets it spinning around nicely.
One wonders how many joules of energy you could get on 300 degrees of rotation, i might be wrong, but the wankel normally does not suffer a lack of torque so using stepper motor as bearing and generator would be a quick way of knocking something up. I have to think small unfortunatly as everything i have made so far has been made outside on a plastic patio table..LOL
