All Permanent Magnet Motor

[conradelektro]

nothing rotates. why?  so beautifully made. tried so hard. 

Of course I do not know, but my guess:

- bottom ring magnet is too big and too powerful (it somehow holds the top ring magnet from rotating freely)
- 45° magnets too small and from the wrong material (Ferrite or Neodymium?)
- angle of rod not correct (not necessarily 45°, could be a bit more or less, angle and weight of rod should be adjustable)

This is why I wanted all the specs and photos from magnetman12003 (Tom). Tom probably had many not working attempts till he found a configuration that just works. And every replicator has to go through all the errors unless he gets the exact specs from Tom.

Guessing when replicating is hopeless. But your replication is indeed a beautiful contraption! And be aware: with permanent magnet motors the inventors are always very very close, just one more little adjustment and it will turn by itself. Sometimes the motor turns by holding "something" by hand, but if this "something" (additional magnet, rod, whatever) is mounted the motor does not turn. The search for a permanent magnet motor is an arduous path.

little neodyo. degrees 45. nifiga does not spin.

I have taken this to a new level now. I removed the large 5 pound top spinning ceramic magnet entirely. So now all you need is one large ceramic ring magnet, 4 grade 50 neo block magnets, and parts that could be bought from EBay, McMaster Carr, Lowe's, or Home Depot.


Make what you see in the lower photo. The bottom of my magnet blocks are South Poles.
They face the South Pole of the large stationary ceramic ring magnet below them.
I have two full ceramic wheels stacked on the center rod between both so the setup spins extremely fast.

Why the excitement?  Now I m not pushing the 5 pound ceramic magnet around. Only the 1/4 inch thick wood disk I have my 45 degree magnets bonded to. That disk pivots freely with a finger touch. 
When a threaded rod with a SMALL weight on it is touching the 45 degree magnet the setup spins EXTREMELY fast using your fingers. That same idea takes place not by using your fingers but by using a tumbler with the top side holding the weighted rod at a angle.  I am waiting on some tumblers right now.

What happened to the gray stucco feature that appears in the picture below? Your 5 pound ceramic magnet is missing?


This represents a radical departure from your original design! Now it's identical to "egotronic's" fan blade design.

There is nothing to replicate because replicating would require a working device in the first place.
