@wizkycho and all

To allow an easy to build device I changed the design a little bit. Please look at the picture. Only 3 magnets would be needed. 1 ringmagnet as stator and 2 diskmagnets as output-rotor. The picture is only a scheme. In my opinion this design would work too if the working principle is valid. What do you think?

M.

May I, with Your permission put this lower complexity type on my site ? I'll make an animation.

I allready have 20 pieces of very strong NdFeB round magnets for Outputrotor
dimensions are? 20mm diameter 1cm thick properly polarized.

BTW: this one works on repel. can we think of attractional analogy of this device - and prolong working period from
500 years to more than 1000 years and desolve any susspicion that may apply to repel action of original device ?
this just for some brain storming.

I also have strong NdFeB round magnets (N42), and I'm going to get some Ironplates.
I order my magnets at www.supermagnete.de, they are also offering comm. specification ordering and I will ask for a ring magnet size 100mm x 20mm x 10mm.

If the idea is working, we will have a prototype soon...
Tell about your experiences while building.

Of course. No problem.

i advise You to reconsider using bigger diameter of ring. Between to sides (180deg) of this ring 100mm is only 60mm 6cm. And if magnets are NdFeB and strong Ring puts repel force ONITSELF and discharges (not quickly? but still does).
Rotor magnets will allso repel each other at that distance (very noticeably), which is going to weaken ther action.
Many other unexpected things (more likely unuseable) can arrive from this i think underdimensioned ring
if using 200mm diameter the space between to sides is 16cm and at that distance you can not or unnoticeably see
(feel) repel between two magnets NdFeB (N42).

100mm would be cheaper BUT BETTER RETHINK IT

Here (picture) is a device that works (I doubt it) with attraction. What do you think?

M.

P.S.: I have an additional idea. If we can't make the iron-output-rotor follow the unshielded area horizontaly we can make it going up and down when the area under it is shielded/unshielded!

This could work but difference between Hill and Walley is very small. So small I think it wouldn't be enough to give any
excess power (not even in FE mode)
maybe something else ...

No answer from www.supermagnete.de to my questions about larger ring magnets (i asked for 100mm to 200mm diameter...). Will resend my request today.

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.

Good work, you are first. I'm waiting for answers from supermagnete.de and will go off today to get some steel.

Any idea how we can measure forces. For testing, it would be enough to raw measure N at output rotor and compare it to input. If there is only a little higher out, i will cut a caper...

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.

@ooandioo

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.

@magpower

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.
