Using a shield to assist swap of polarity in a magnet

[Low-Q]

That is a good idea.
The problem I see is to maintain those magnets in line to enter the magnetic shield while circulating around.

As a start it should be absolutely possible to use fewer rotor magnets, 1, 2, 3, 4, 5 or so. They will behave separately in the same way as if there was an array with a bunch of magnets. What I mean is, if it works with 1 magnet, it will work with more magnets, even an array. It wil also work with only the the stator magnet in the middle (if it works with all stator magnets in place)

Here are an alternative way of making this motor. The main key here is to shield the polarity swap of the rotor magnets, so no energy are lost during this process.
In general this motor work as an electric motor which do swap magnetic polarity due to the alternating current. However this design does this mechanicly.
I have put my name on the drawings, just in case this motor work for real

I do hope more of you understands how I want this motor to work. So hopefully someone would assist, question, and even bust the design by telling straight out the "evil" truth. I really, honestly, cannot find the flaw of the design (Except "it should not work", "bending physics", "violate laws", etc.). If you guys can see the flaw (except violating laws of physics), please tell me, and explain where the mistake are made.

I have called this motor "SWAP"

Hello

Very interesting project. At first I cannot find out why it should not work.
On the other hand please try to explain me the difference to my NoSwap design. If you change the polarity of your stator instead of turning the rotor magnets.
In the NoSwap design, if the rotor magnets are on top, I would expect a very strong backforce, impossible to allow a full turn?

Thanks

that last pic will come to rest with the first ,~2 mags near polarity switch...........shylo........Vidar I like the idea of a shield...the only problem I have is the shield being saturated ? what type of material could this be made from.....shylo

I have been thinking of this scenario you were drawing. My "logic" tells me that this particular design, with all fixed magnet polarity, will definitely not work. I was rather thinking of a virtually rotating magnetic field, but still rotating the mass. The array in the animation was done simple because I hadn't time to make all magnets in one complete round (My wife was yelling at me "come to bed ASAP - I'm TIRED!"). So the anmation only shows the principle of operation inside the shield.
My idea are based on having a center magnet with polarity horizontally aligned, and stator polarity aligned vertically. There will be a torque in the rotor magnet as long it stays horizontally, but rotating that magnet would eventually ended up in-line with the polarity of the stator magnet, and ends there without further motion. If we devide up this rotor magnet in many smaller ones, and let them in total feel the same torque, they would be forced to go in-line with the stator field. But what happens is that when every time one small magnet goes into the shield (half way of one stator magnet), it flips 180 degrees so it can exit in repelling mode - as all the other following magnets now are all the way 180 degrees - to the next shield where the polarity again flips 180 degrees.

Simulations shows that there is a great torque in the array, and it also shows there is not energy required to flip the magnets one by one 180 degrees as they pass through the shield.

HOWEVER! If the shield isn't there, it will require great amount of energy to swap polarity - just as much as the energy supplied by the rotor array magnets in its whole.

So what I have found is that without the small shields, the motor will not work. The shields are the only reason why it doesn't require energy to swap the polarity.

Ofcourse, I cannot claim any overunity yet. There is most probably something that isn't working in practice. So I have decided to build a simple prototype. If I manage to make one, I will show it to you on my Youtube channel - working or not.
