I find it hard to believe it could start it on his own, and in the same time it will accelerate in either direction when initial spin is applied to the rotor. These bearings motors are known for long, as I know there are plausible theory's on how it works. It is possible to do calculations on torque (using today's electromagnetic theory), etc.., prior experimenting, and the result will match the reality. The bearings are necessary, and the explanation involves them deeply in the generation of the additive torque. As WW mentioned it worked without the bearings,I got very curios and made today a test rig. I used 4mm diameter Tungsten rod, with a small metal "flywheel". I made 45 degree angles on both ends of the rod, and balled up the points with my TIG welder. I got two near perfect half ball on both sides. I drilled two bolts in the ends a little to make the holding part of "bearing". Installed everything in a wood platform. Sadly it didn't work. I tried with 12v and 6v (high current capable battery). The tips of the tungsten are looking well after 20-30 minute on-off testing, tolerating the heat very well. I could try different materials for the rod, but to be honest I feel stupid when I think about what am I doing in this experiment, and what result I'm aiming for. Can it be true? (acceleration without bearing) Poynt where are you? Tell us what's happening here! WW Could you please tell us more about your the bearing less "bearing motor" experiment?
