New permanent magnet motor on youtube from Roobert33

[Omnibus]

Two years ago or so I was doing it with a triangular iron sheet. Same thing. Haven't posted it but I might as well do so when I go to Massachusetts sometime next or the following week. We'll see how it goes.

That should be interesting to see. If you recall @xpenzif's "screw motor" rotor was all steel. In this case it doesn't matter and, ike I said, V-track is only a distraction. It has no significance at all. The same effect is achieved by, say, a spiral of magnets. The concept is pretty trivial. A lot of tweaking is needed in any of these well-known cases, though.

No, this is related to a "V" track! Let me explain what the data shows. If two metal cylinders are close together on a "V" track (like at the start), they become magnetized in the same direction. This causes them to interfere with each other and not become as magnetic as the next set further away from each other. So the stator is attracted always more to the set further away.

Now as they pass under the stator, they change polarity and the situation continues. But under the stator, the cylinders are magnetized horizontally which they do not want to do so the stator can be easily pulled away. Unlike a conventional "V" track with all magnets where the stator continually becomes more attractive as the track widens.

Anyway, the attraction is based on a totally different concept of operation than a "V" track with magnets on the rotor.

Lumen,
Funny thing,Some of the fellahs in the beginning of this thread said those were not magnets in the V,but metal slugs?

You know, that's very interesting if that's the case and has to be studied more. Several months ago, however, I made a drum with steel cylinders just like the ones in @Roobert33's case and the the result was pretty mediocle, compared to the case when I replaced the V-track steel cylinders with agnets in a spiral. As I see things now, if there's any promise it would be with that magnetic spiral rather than with the V-track. However, your observation may have some merit and probably I should reconsider my current position. That's why I'm looking forward to seeing your model and results.

I should mention how my spiral rotor works. At the beginning of the spiral the stator N is facing the spiral N and repels it. As the rotor turns, the repelling decreases but the attraction increases and this is the reason for further truning of the drum. That happy conditions would end at the minimum of the magnetic potential energy but this is where the cam kicks in and causes the rotor and the stator to distance themselves. That moving apart has a significant effect even if it is slight because the force of magnetic interaction decreases with the cube of the distance. So when tweaked successfully the excess energy acquired during the turning of the drum will be sufficient to pull apart the stator from the rotor so that the sticky spot can be overcome and a new roind of turning to begin. That's typical negative feedback. So, that's the whole idea in a few words. Would be interesting to see if you can model that.
