A SQUARE MAGNETIC RAIL -- ROTOR 360 ROTATION

[TinselKoala]

Untill I get my design up and running, I think that I will just try helping other people to refine their designs.  And while I am labelel a "newbie" on here, I think that I can bring some very valuble knowledge to the table.


Actually yes you can.  You just have to know how to manipulate it.  Search "Halbach Array".  I think it will be the key to making so many of these magnet motors actually work.  Another thing is to always try to make these MM produce movement by attracting rather than repelling.  Over time even when permanent magnets are forced to repel each other they will die.

Several people have tried to point out to you that there isn't any tangential force asymmetry in your design, so the rotor isn't expected to want to turn.

Depending on the magnets, you are wrong about permanent magnets dying in repulsion. What kills (some) magnets is being exposed to fluctuating fields stronger than some limiting value. For modern NdFB magnets you are extremely unlikely to be able to achieve this condition in a mechanical arrangement, so your magnets will not "die". Magnet manufacturers often display large magnets suspended in repulsion, even supporting weights, and show that they do not lose strength even over long periods of time.

Finally, many magnet motor researchers know that using attraction instead of repulsion produces difficult-to-overcome "cogging" or walls of mutual attraction (energetic wells or minima) that may be avoided by arranging things in a repulsive orientation.

Observe the 4 different track rails.  I have built four number ones. Look at the magnetic polaritys of each rail. number 2 and 4 are not to be used.

 I am sorry Tom but your design will not work as you plan for it to. You can not have one with our the other nor can one be stronger then the other.  Your design closed a loop which created a inner and outer polarity. The inner polarity will have the same strength at equal points away from the center.


gregs78cam, the "Halbach Array" acts like a horse shoe magnet. The bottom of the U is less powerful then the top. You can not have a magnetic field unless it has a north and south and the will always have a equal strength. The same goes for the separate polarity's, they two will always have the same strength from the center of the polarity.

ok, thank you.

Greetings magnetman12003

A few people here will remember that I have written about a magnet wheel that I claimed in 1974 that I did for a school project. It ran for 1 1/2 days before it tore out the middle of my cardboard center. But it ran in a jerky motion which probably sped up its demise. Wracking my brain to remember what I did I remembered that the magnets made more of a square outer edge. What you are doing is taking me back again so I will follow your progress and help if I remember anything useful.

If you have any questions please ask, for this may help me jog my memory as well.
