Introducing the flowerpot effect (rotary shaft magnet spinning out of control)

[AquariuZ]

This is essentially a one magnet no bearing bedini motor, but with a shaft and bearing, using a diametrically magnetized tube magnet.  This works with the sphere magnets as well, and I have generally considered this to be a tuning factor of these types of devices.  This could effect the inductance of the coils, and the voltage induced along the trigger coil, which would in turn effect timing.  I like to envision it, however, as though it were allowing the overlapping of the interacting fields to behave like interlaced gears... get the positioning right, and its like the invisible gears line up correctly.  I show and describe the effect in this video:

Very interesting. I really like the gearing (magnetic coupling). Also as Tom describes it.

   I  already put a 1 pound load on the shaft and that spun with no problems.  A 16 inch diameter iron wheel was spun also. See the lighted  scooter wheels video.  I wish I had a way to measure shaft torque but I an sure someone that has access to a laboratory can replicate this and check torque.

What I really like to understand is why the magnet takes off like that when raised higher above the coil as opposed to sitting directly on top?

Is it because of stronger LENZ-effect when the magnet is too close to the coil?

It would be nice to try and find the optimal distance and then try to couple your flywheel to the magnet.

I will go through your links:

Thank you for your great work!

Hi, nice work ..


I was looking at the site: http://peswiki.com/index.php/OS:Tom_Ferko%27s_Satellite_Generator


I found out that the magnet cost around 175$ for 1 unit. I wanted to replicate it but, its kinda of out of my R&D budget.


Would it be possible to repro. your setup using low cost parts?


Also another thing to always keep in mind,  Your actually using 3.2W to power 4 leds and rotate a "not under load" Magnet!   

It would be nice to correlate the speed vs input Watt usage and make a graph out of this.

Same here... 

But there is hope. If have so many Neos lying around here I think I can create a stacked assembly around an axle to at least try to replicate the acceleration. So I assume polarization is through the side away from the axis (diametrical).

Ah yes - diametrical - so not through the axis. thanks Twinbeard

Wow that sphere rotor really stepped up frequency once you lifted the tube out.

Did you try and wire a pickup generator coil around the assembly as you mentioned in the end of the video?
