Magnetic Motion Device

[DreamThinkBuild]

Hi All,

I've had a paper from a Mr. Arthur Joseph Cote his invention, Magnetic Motion Device, is to use two magnets(rotor) that are separated 23 degrees apart. These are put in a track(stator) that has magnets closely spaced but angled at 45 degrees on either side. In his document the north is supposed to repel off the north facing magnets but that wasn't the case. It works in reverse. If you try to flip the magnet it sticks and locks badly.

I'll use the terminology of rotor as the 2 magnets 23 degrees apart. The stator as the 45 degree magnets on the sides.

Initially there is a gate where the N of the stator and N of the rotor is pushed in. Once the back of the rotor clears the first magnet it will shoot out the end with no gating or pull back. Measured with a ruler from exit it shoots between 7 and 10 inches out on smooth flat table. If I place a large glass marble at the end it will shoot the marble off.

I've included a shot of the field pattern which is very cool. The stator creates a barbed angled pattern and the rotor creates a triangular pattern(looks like a bullet).

The 10 N42 magnets are from CMS Magnetics on E-Bay they are 1/2" x 1/4" x 1/8" (12.7mm x 6.35mm x 3.175mm). 100 for $28.

I'm including the 3D files which is the actual print model(.STL) I used to make this for those that want to build, test or analyze it further. Measurement is in mm, the magnets are scaled for ABS with a .40mm nozzle diameter. May have to tap the magnets in with a small rubber mallet as I made it all friction hold, requires no glue or tape.

Also attached is the original doc and some distance tests with shooting the magnet out (sorry for glare, flash was on).

Any ideas or suggestions?, please post.

Nice find DTF - interesting document.  I noticed he used ceramic magnets which have less power up close but have more strength at a distance than Neo Magnets the way I understand it.  Considering the slingshot video's I've seen using magnets I've always felt if one could build it into a reasonably large circle that it would be self running.  I'm not sure what kind of power you could get and overall how affordable it would be as a power source but it would be very cool to see a self runner.  It seems lately I've been again bumping into a number of articles that claim magnets CAN be used as a way to generate power (self running).

Nice Dreamthinkbuild, if theres no dead spot in that setup maybe posible to selfrun if built in a loop, is it like a howard johnson design?

Hi E2Matrix,

I keep hearing reports of working magnet motors but it's always elusive stories just like bigfoot. In my experiments I always find them static. The only way I can find out is just build and test even if it fails break it down and find out how and why. This track caught me off guard the logic is saying it's going to stick at the end, but didn't and goes in completely opposite of what it looks like it's supposed to do. That's why it's important to test even if it's just a small model to see if it has any merit to continue.

Hi CrazyCut,

I'm looking into making a round test version. A flat version would be the easiest to construct. The barbed pattern that the stator produces is very important, from observation and constantly playing with shooting at things on my desk it appears to squeeze the rotor out.

@All,
I'll do some more tests with some curved pieces and see if I can maintain that barbed pattern. May have to move one of the rotor magnets in to compensate for the difference in angles to the curve.

We all know the expirement at the start of this thread does work and curving it to loop is the goal but why change the structure? He shows four magnets on either side driving the two magnets down the track.  so why not just make the track longer and curve it up and back around? Granted, we're talking about a lot of magnets but the principle can be shown to work  by merely building a longer track and curving it up on one end to see if it will work. If so, turn the track on its side rather than an up or down loop and the gravity issue would be minimized.
Just a thought that if given the time I will attempt. Two rotors conected by one shaft would keep both in their position and give us a way to tap whatever mechanical power might be there. For that matter, four rotors might even be better. Ceramic bearings on the rotor will minimze drag. If the single rotor will make the turn, this should be doable.
Can't yet envision how large the track might have to be...
