@ All

I am starting to replicate the Lego device. :o
...
If anyone has suggestions, please drop them in the box.  ;D

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

@ zerotensor

You just gave me an idea for the background soundtrack.  Thanks.

Yada ..

Man it would be nice if this simple motor actually works. Especially since it is made out of Lego's which are easy to get ahold of (of course). Has anyone tried to contact the guy who made it?

Well, this guy replicated this Lego pmm, but instead of using rubber bands as pulleys, he uses cog-wheels.
His version does NOT work at all.
Check out his youtube video: http://fr.youtube.com/watch?v=sVMXQwha7aY&NR=1

I was getting dimensions for the magnets (somewhere around 50 x 20 x 20) when I realized something very peculiar: 

--- The four stator magnets are located below the four rotor magnets, which is to say they are oriented like in the WhipMag.

Now, it seems to me that if someone were faking this thing, they would have placed the stator magnets and rotor magnets in the same plane to make it look pretty, then made a video and called it a day.  Perhaps -- through trial and error -- like Al they discovered that the rotor mags need to be elevated above the stator mags.

Hmmmm ... ???

I love puzzles.

@ Koen1

You know, when I first saw the thumbnail of that video I completely ignored it, because it didn't look anything like the original.  All I saw were the gears and completely missed the point -- that it was an attempt to replicate the principles of "Lego 1" without rubberbands.  Clever.

The gear/cog meshing in his device clearly dampens the overall movement, and there's no telling what he's using for bearings (if any).  Clever, though.

Thanks for the link.  It's encouraging to see that someone is attempting replication.   ;D


Cheers,

@ Koen1

Looking at the video a second time, it appears that his rotor and stator mags are in the same plane, which is not ideal for the WhipMag and possibly not ideal for his device as well.

I wonder if the builder posts to any of the magnetic/energy forums??

I personally feel that this motor may have some merit. Some people were talking about their being a hidden motor underneath the table or something, but if you look at how the thing is actually accelerating, it *seems* to be acting like it is moving because of the magnets. Now, with that being said, I didn't bother to look at the video frame by frame to see what the positioning of the magnets are. But even if they were going in the  wrong direction with the wrong polarities facing each other, I would still not discount it immediately. Anyone who has been following the MPMM replication will tell you that the motion of the anti-gearwise stator magnets is counterintuitive to say the least.

God Bless,

I tried to contact the guy, wrote him a couple of PM's on youtube but never got a reply.

One cynical way to approach this is to suggest, as @zerotensor has done above, that the Lego guy is just showing backwards the video he has taken.of the device.

lol that's a very cynical view for someone who fills his own thread with tons of dodgy math but no proof whatsoever, and then starts insulting people who point that out... ;D

@Jason O

Something ive found interesting is how a magnet's tangential pole has more power to push or attract given its placement.  Just play with two bar magnets , feel the field shape with one in repulsion and at a certian downward angle (magnet below another one like the stator magnets placement you talked about) you feel an even stronger push or pull then the normal head on one.  What would be beneficial is to take into account magnetic field shape and density to hit the sweet spot when the rotor passes .  Just a thought but the placement of the stator magnet has got to be the key so the rotor  kinda sling shots off of it.  If one would be able to find a formula that was for the diameter of rotor  vs the diameter of the stator magnet and the time the stator takes to do one revolution and the time the rotor takes to do one revolution. Once the proper diameters were found , timing that interaction precisely so that the rotor magnet gets the full push would yield a system of high efficiency and  incur much less loss because it would me a mechanical self resonate system . That would only leave the x and y coordinate spacing left to play with and would be much easier with the other variables eliminated.                                                             Joe

@ Jdo300

Jason,

I've seen your CAD skills.  Nice. 

If you grab a few screen shots from the Lego vid, and use the two base plates as "grids" you could probably dimension the device very quickly.  Add to that, Lego blocks and plates have standard 1" features, and 1/2" centered studs (I think ... I'm picking some up today).

I've started the reverse engineering process, but a second independent effort would be appreciated.  ;)

As for the magnets ... the bright colors and plastic case suggest they are from an educational supplier, thus size could be defined in either metric or imperial units.  They appear to be around 2.5" x 0.75" x 0.75" or 65mm x 20mm x 20mm.  I need to to do more sampling.  Although I've seen educational neo's that were encased in blue/red plastic, I doubt these are neo.

Cheers,

Yada ..

@Yadaraf,

Isn't the beauty of constructing this is that it's built of standard Lego elements? Why bother with CAD? The only problem is that nowadays one cannot find just a set of Lego pieces but everything is turned into this or that construction. I guess the profit is higher this way. So one has to buy a bunch of unneeded stuff to get the full set of pieces to assemble what one needs.

Hey Yada,

I looked at legos a little while back.

They do indeed have standard units, but they are their own special Lego units, they have a name for them I forget what it is. The lego website is very helpful. The Lego units unfortunately do not fit into any other standard units.

On the Lego website they also have their own free Lego design software, sort of a basic CAD program for Lego builders. An interesting feature is you can design your Lego thing in this software, and then you can with a few clicks send an order to them and they will ship you all the parts that make up your design. I think you can even pay them to assemble it and package it in a box for you like a custom "toy".

It is also interesting that the individual Lego parts are made to a very, very high standard of precision.

@ Omni

IMHO Lego CAD -- a.k.a. Ldraw -- will be a useful tool for documenting this device.

.... http://www.ldraw.org


In any event, I have to use a computer to reverse engineer the screen shots, which are quite distorted and blurry.  Specifically, I'm using a CAD program to rescale and resize the screen shots, which are skewed about 85% front-to-back.  I'm creating CAD rulers as I go along, using the base plate studs [centers] to calibrate the rulers.  I say "rulers" in plural, because the image skewing requires that I apply different rulers when dimensioning foreground vs background objects.  Also, the rulers allows me to dimension "Lego unknowns," like the magnets, spools, etc. 

Even obtaining the length of the rotor support braces is tricky, because the supports are black and practically featureless, making it difficult to dimension the end caps in particular.  Difficult ... but not impossible.  I've already caught one or two dimensioning mistakes, so a second opinion from Jason would be useful.

Having said that, I'm making good progress.  :)

Cheers,

Yada..
