Was looking into doing some work with induction and stumbled on this recent video by a tinkerer.
http://www.youtube.com/watch?v=MGxdM2JCLrE& (http://www.youtube.com/watch?v=MGxdM2JCLrE&)
He is afraid (justly so) about the 2inch spinning magnet flying off the flowerpot and stops it near 6000rpms.
Just thought I put this out here as is. He titled it "maybe Newman like motor" but I do not see anything related to rapid polarity changes.
I would appreciate it if you veterans could have a look and give your thoughts on the observed effect please.

First questions come to mind
- Anyone recognize what type of magnet assembly this is?
- Standard copper wire coil - what type?
- Anybody recognize the man in the video?
- Can we contact him?
Invite him on the forum
Thanks

Grabbed the video just in case it disappears. I also left a message on his channel.
I found him - his name is Tom and he already has an account here...

Tom has been here before - I just spent some time reading his posts and seeing other videos.
So nothing special about this 2inch spinning Neo held over a coil connected to a bendini circuit (appearantly)?
Something pulling 0.9 watts making a magnet accelerate like that? Wonder what you can generate if you put a load on the shaft.
Hi All,
I am magnetman12003 and POPSCAN1.
I invite you to look at all links below where I show how to construct it and I have included the parts list.
I open sourced the setup and its published world wide now." PLEASE JOIN THE FORUM" the publisher setup for me. A lot of info is there also. ITS ALL FREE. I dont want this technology to vanish as things that are to good often do. The cats out of the bag!

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:

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.

Hi, nice work ..
I was looking at the site: http://peswiki.com/index.php/OS:Tom_Ferko%27s_Satellite_Generator (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.

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

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.

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?

Thank you for your great work!
For these circuits to work optimally, you want a very small "on-time" for your transistor or MOSFET. This on-time will be proportional to the length of
time the voltage induced in the trigger coil will be above the on threshold of the tranny. By moving away with the rotor, you are decreasing the number of lines of force from the rotor cutting the coil pair, and in particular, the trigger coil. This limits the voltage induced across the trigger coil.
When the tranny is off, there is open circuit across the drive coil, and the rotor is free-wheeling. When the tranny is on, the moving rotor, while accepting the pulse, is also causing Lenz drag, even if for milliseconds or less. The "sweet spot" occurs at the point where the transistor just barely kicks on, and this is, of course, also effected by the (generally variable) resistor value on the base of the transistor, but that is limiting current, not voltage.
Cheers,
Twinbeard

llewgnal did. I worked a few different directions on this device in various forms. Take a look at his youtube channel:
http://www.youtube.com/user/llewgnal/
the stardrive 2.0 series is where he shows that style of build, iirc.
i have several different motors of this type, each with different pickup coil configs... generally lots of turns of small wire works well.
