Rotational PMM by wizkycho

[wizkycho]

Any news from you guys?

Don't blame me for the ferritringmagnets. They are pretty strong too. Demagnetization is not the problem for me, because it's a only a personal test and not the solution of the "world-energy-problem". And they are easily available.

What I need now is steel for the shielding and some electric motors as motor/generator. That should not be the problem.

what are dimensions of this ferrites ?

@wizkycho

outer diameter: 6,0 cm
inner diameter: 3,2 cm
thickness: 1,0 cm

So they are relatively small, but easy to obtain. I will see, if I get problems.

Yes, big rare-earth-ringmagnets would be ideal. But even bigger ferrit-ringmagnets would be nice und surely cheaper. Maybe that would be an alternative.

I hope you get a positive response.

Nice drawings but have questions. Which way will the rotor turn? I can't see how this will turn CW or CCW. Maybe unless you shape the iron in a triangle shape. Also you can get large rings from old speakers. I got some up to 3" dia.

The output-rotor will turn in the same direction you turn the input-rotor (shielding). If you turn (with an electric-motor for example) the input-rotor cw, then the output-rotor will follow cw. The same for ccw. You need an permanent energy-input but the output will be greater, so you can close the loop. At least I hope so.
