Quote from: Classic on Jun 25, 2024, 01:23 PM@Ufopolitics, his magnets are fixed in this setup

Hello Classic,

Sorry to disagree with you, but no, his magnets are not fixed.

The magnets are embedded in the ends of the bellcranks or rocker arms. The opposing magnets do move in relation to each other - in fact they move up to 40mm apart and approach as close to the rotor fingers as they can without actually touching it (the limits of their movement can be adjusted - one of the reasons I needed to redesign the device was to introduce this adjustment mechanism).

I hope that clarifies things.

I got it, many thanks for explanations. I had a different picture in my mind and obviously is missed that part on initial description.

It seems far more complicated then it should be ... from what I see this is a non starter for diy replication unless someone spend a lot of many ordering parts or have an extensive mechanical workshop. None the less looks very intersting, looking forward for tests and proof of concept.

Well, I live in a caravan and my workshop is mostly mother nature at the moment. I have basic tools and I'm just using 3D printing at FabLab. Really they just charge for the materials and a bit of time. This version is just to clearly demonstrate the principle and to offer proof of that principle, if the device performs as my experiments lead me to believe it will. It can be made in many configurations - some I have already thought some way through. Having sprung magnets in solenoids might be practical. But let's prove the idea before having to explain electrics and electronics to people.

I understand the principle, so I am able to imagine many different ways to use it, if my understanding is correct. I don't think it is difficult to grasp; my local village café owner, who is also a farmer and runs the village shop, immediately understood what I was showing him - which is quite something because my Portuguese is rudimentary.

If people would like information about it, I have made it freely available and people are welcome to repliacte it in any form. I'd be interested to hear about replications. On another forum someone commented that they had carried out their own experiments and their results confirmed the claims I put forward.

The bearings were very expensive here. They cost 36.96 euros for the three. Bearing Boyz online offer them for a couple of quid each but that would involve postage and that would involve the Portuguese post office and that would involve ... so I paid the premium but others don't have to.

5mm steel (or even stainless steel if you're feeling flush) rods are quite cheap. 5mm allthread likewise. M5 nuts, screws and washers, not much (watch out though, some of the China shop nuts are of varying quality and some may not be close enough for embedding in the print).

Hello and thanks @Prajna for your detailed explanation(s)

I do see how the mechanism of both swivel arms with magnets works with the rotor uneven slots-'fingers'.
So, when rotor metal is at magnetic gap on one side, this closes arms carrying both magnets (attraction), while at 180 degrees there is an open gap, allowing repulsion forces to act fully.
These Repulsion forces "assist" the closing on gap at other side...and so on, it keeps balancing the arms back-forth movement.

But honestly, what I am failing to see, is the propulsion mechanism that would cause rotor to spin[color=var(--input-txt-color)]...because this attraction points from both end magnets would tend to stop/brake rotor,[/color]

like a "Brake Caliper Effect"...and I do not see the Repulsion at opposite end to cause rotation, but only to compensate/assist the attraction on other end.

Anyways, I wish you a great build, and would be waiting to see results.

Btw, do you have any videos, even on the old setup, that you could upload here?

It would be great to see mechanisms working.

Sure, my channel is https://m.youtube.com/channel/UCuXjvvt722O9R1PIg9ILMog - it's the Mk-4 version but it should give you the idea.

That version had a big handle to indicate that the rotor does not turn itself, it must be driven. All this is explained on my webpage. The point is that if the energy required to turn the rotor is less than the energy output by the flux switching then we can drive the rotor from the output (by any means known to someone skilled in the art, as they say) and, we hope, have a useful remaining output).

I hope that was useful.
