Working Magnetic Motor on you tube??

however, the previous figure--the dampers appear to make a noticeable difference. Haven't tried with dampers yet.

Yep got to agree this is more interesting.

@Craigy,

I think @CLaNZeR said you've sent him the magnets. Do you happen to remember what grade they were? At least, are the stator and the rotor  magnets of the same grade (say, N42)?

A reminder to the replicators from the original thread.

Seecond, not all magnet/bearing pairs will produce the effect. I have 15 of the magnets, and 13 of the bearings. I have not tried all possible combinations of these, obviously. But of the 13 assembled magnet/bearing pairs, 3 don't seem to work at all, 2 are fairly easy to get started, and the rest are somewhere in between. Even the "easy" ones usually require several tries before successful engagemen

Third, the relative height of the stator and rotor magnets seems important. I don't know if it's because of my particular geometry or whether it is critical to the effect itself, but the magnets shouldn't be in the same plane--that is, I am getting best results when the rotor magnets are rotating in a plane that is just slightly higher than the tops of the stator magnets, rather than down and centered vertically

Anybody, Does anyone have a source for n30, n35 rotor magnets in europe? That link previously has a min order value a bit high and they don't post out of the US.

Hi Craigy,

Here's the one I posted a week ago or so:

http://www.monstermagnete.de/catalog/advanced_search_result.php?keywords=Z06

They have N35, 6mm diam. (6.35mm would be a quarter inch) cylinder mags that are 13 mm long (12.7mm would be a half inch).

Just in case, here's a repost of the American mag companies that carry quarter inch diam. by half inch long N35s as well:

@Clanzer,
Re. you graph, its very interesting to look at the blue line, with the hickups at the start, if only they are able to carry on. I guess the fall is when sync is lost.
I do not understand the purple (standard run down) time being linear, I would expect it to be curved because of air resistance at the higher RPMs.

I wonder if the saw tooth is the agitation of the stator?
Are the RPMs the rotor speed or stator?
