I happen to have a disk motor here in my workshop museum that apparently uses the same principle, about 12 cm diam., very flat. It runs without electronics, so I supposed it had brushes inside. The rotor must be also etched from a disk of sheet copper, simply plane, rotating between two rings of magnets, with very little inertia. I haven't found an application for it yet, though. The housing is riveted and I hate to open it just for curiosity -:)

Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-novd2d _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
