Magnetic bearings
« on: June 28, 2011, 12:45:49 PM »
In some other thread Dave45 posted link to this video: http://www.youtube.com/watch?v=2R4QQmCY4JU

I started this new topic because I was afraid that this info would be lost in that (non bearing related) thread.
I think that this would be great bearings for our diy motors.

You can read more about his technology here: http://www.magnetal.se

And on their website is also link to thesis containing all the info one needs to make the bearing:

Have fun,

IIRC the web site made it sound like 5000 rpm was about the minimum these will operate well at.  That would be too fast for the home built Muller/Dynamo for a couple reasons.  One there is evidence the 'magic' speed is around 1200 rpm.  The other is most units would blow apart dangerously at 5000+ rpm unless built to extreme precision.  I think there are other types of magnetic bearings that would work at slower speeds but that was the impression I had from skimming this web site.

Have a look at some bearings I suggested earlier here: http://www.overunity.com/index.php?topic=10716.90 , reply #97
Pretty simple to implement.
I've seen some youtube videos of a guy using these in some sort of way, I'll have a look whether I can find those.

[update]
Here's one from Lidmotor: http://www.youtube.com/watch?v=PjmJX4thhGA
Another one from Dadhav: http://www.youtube.com/watch?v=VHJRWL42rCU

I have tested your suggested design.
The magnet in the middle will instantly jump in the center of one of the ring magnets.
I think that Mendocino setup should work better. I will try that because it's tested to work...
