New accelerating lego magnet motor on youtube
« on: September 22, 2007, 12:55:00 AM »
Hi,
here is a new "lego perpetuum mobile"
done from lego and some permanent magnets
and some rubber bands acting as gears:

I hope that it is no fake.

Regards, Stefan.

Looks like the arm magnets individually rotate once per 1/2 rotation of the whole mechanism.  I need to look at it frame by frame in more detail, but it also looks like at each 90deg each arm magnet cycles continously from repulse to attract with respect to each of the stationary magnets. 

So its a magnetic planetary system, rotation and revolution.  But in this case, the rotation of each arm magnet moves the bands to create the central rotation of the entire mechanism (which is revolution from the arm magnetic planet perspective).

IF this isn't a fake, I should think you could model this in software.  And of course it should be easy to replicate as well. 

I think I'll have some Guinness and come back later to look again!

Regards,
jeffc

Forget the frame by frame, just listen for the click of the switch as the camera moves off center obscuring part of the setup.

G'day all,

Me on another thread about the same device:

Hans von Lieven

G'day all,

Wishful thinking FreeEnergy,

It is obvious the device is driven by a motor concealed inside the box it is sitting on.

When you have a close look at the rotor magnets and their behaviour (by going through the video frame by frame) you will see that the magnets do NOT impart rotation to the device but react to an outside force.

Sorry fellows, someone's idea of a joke.

There is no real click sound. Just some microphone clatter.
But as always, I don't thrust a video not showing the whole setup. And there shall be no editing.
In this case the whole area around and below the motor is not shown.
Then he should also lift up the lego device from the table to show no hidden wires.
Finally he should disasemle the whole unit in front of the camera to show no hidden built-in motors and small batteries.
Period.

I have quicky analyzed the video. The magnets are not working in the way the "inventor" had in mind. The rotor is accelerating in positions where stator and rotor magnets are facing and approaching the same polarity, and retarding where the magnets are facing and approaching the oposite polarty - more or less randomly ::). I guess the magnets are made of plastic, and there is a motor under the table...

Even though this video is fake. Is everyone in agreement that this idea/concept is not worth attempting?  Has anyone try to replicate this?

The sad thing about magnets is that they will allways interfere with each other. The sum of repel and attraction is allways zero. The reason is simple: You cannot destroy or create magnetism on demand without using energy. Destroying and creating magnetism is the only reason why electro motors are running, but not motors with permanent (None-altering) magnetism.
No matter how you configure magnets, and no matter how you shape them, or mix it with iron, - destroying or creating magnetism cannot be done on demand - according to scientists and magnet manufacturers.

"Why don't you just turn the magnet around to create an oposite magnetism". Turning a magnet which is "busy" with attracting another magnet, is hard to twist - it recuires energy to do that.

So: Motors based on permanent magnetism only (Regardless if it is DC-electromagnets or permanent magnets), simply don't work.

I think you are right. I'm already working on this last experiment. I recreated this wheel but I need to get some plastic gears made. If this doesn't work I'm going to throw in the towel. I already spent a small fortune on tools, supplies and lots of time. I think the stirling engine has potential. It's already known to work. It just needs to be sized up to run a large generator head.

Here are some possibly irrelevant thoughts.

We have one example of perpetual motion already. We call it orbiting the earth. The object continually falls to earth and continuously misses. So the thought is how do we get magnets to do the same?

Now here I am making assumptions based on casual observation. Magnetic fields seem to be ellipsoidal.. Could the metal being used to make a magnet be acting or transducing some form of energy such that the it finds it an easier path to travel. (Electricity, water travel on the path of least resistance) So what is making a magnet work is something that likes to go through Iron as it finds it an easier path! Perhaps the magnetism is being induced from a vibrating universal energy.( or these thoughts are stupid)

Back to the ellipsoidal shape and speculation on the inverse square law. Not confirmed this thought but a circle is x*x + y*y =1 so as the two bodies get closer together the sphere of influence increases as suggested by the inverse square law. (However if the influence is a spherical field why is it not the inverse cubed law?)

So perhaps we need some method of pulsing the influence in an ellipsoidal way, which is a coordinated connection with the main turning wheel.

@ All

I am starting to replicate the Lego device. :o

Any takers?

I've captured screenshots and have begun the CAD process.  Because Lego blocks and plates have uniform features, the basic layout should be simple.  For example, the green rotor appears to be a standard 10" x 10" Lego base plate.

... Lego Green Rotor(?)  http://shop.lego.com/ByCategory/Product.aspx?p=626&cn=146

Because the builder appears to be using educational supplies, I assume the 2" magnets are available from a teaching supplier like Dowling Magnets, who I know makes 3" magnets -- bright Blue and Red for teaching :)

... 3" Teaching Magnets:  http://www.dowlingmagnets.com/dyn_prod.php?p=DOW712

At this point the goal is to attempt simple cogging -- if there is any.

If anyone has suggestions, please drop them in the box.  ;D

Cheers,

Yada ..

@Yadaraf,

That's great that you've decided to replicate the Lego motor. Unfortunately, I can't join you right now because I've focused my efforts on @alsetalokin's device. Lego motor replication seems more interesting but I don't want to spread out too thin and would like to reach a certain understanding of the other project first. At some later point I may also join you and everyone else who has interest in this. All the best and good luck with the research. I'll be following it with interest.

When you post the video of it going, just make sure that it plays in reverse!  ;)
