Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

We don't understand why this would cause his poles to switch as shylo claims.

If the neo is too large and the ceramics too weak, then we would expect the poles to stay in the same place and not switch sides. The poles from the neo might be a little weaker as some neo flux is channeled through the ceramics, but the dominate poles from the neo shouldn't be able to change positions.

The only way I see the poles switching are if the ceramics were able to over power the neo or the neo its self is being switched. Both of which shouldn't be possible in shylo's set up. Perhaps shylo's neo is an alnico and he doesn't know it? He could test this easily enough by removing the ceramics and see if his coil switches his neo.

Is it me that doesn't understand?

In shylo's device the neo is overpowering the ceramic magnets in both ways. They cannot store the neo's flux, because if they did this is the time the I's are NOT magnetized. When he tries to re-magnetize the ceramics, again they cannot repel the neo's flux as they are too weak as this would be the time the I's ARE magnetized.

So shylo's device the I's are always magnetized because the Neo is overpowering and what I wrote previously.
This is how I understand it to work, sylo is free to correct me if I don't understand.

I hopes to clear the confusion.

I think the ends of the I's switch polarity, is due to the distance.
The field at the ends of the I's is considerably weaker than at the neo itself.
By powering the coil in the opposite polarity the neo's flux flips the ceramics poles and leaves a very weak opposite pole at the ends.
Not sure about that just what I think.
Luc is your magnet in the center of your coil (the Alnico) repelling or attracting to the I that is attached to your neo? My ceramics are attracted , if I try to place them in the repulsion mode the neo is too strong and they won't even stick to the I they just flip back to attraction.

Yes, as explained in the video the Alnico is the magnet in the center of the coil.

The operating principle is the same as a permanent magnet electromagnet flux gate. However, the difference here is, instead of the coils core to be Iron, it's an Alnico which get re-magnetizes by a single pulse of the coil and holds the magnetization without additional power.

You can consider it a latching permanent magnet flux gate.

Hope this makes it clears now?

Dear Luc,

I was thinking about your system and I am afraid that the energy and power needed to demagnetise the ordinary magnet is of to overcome its own magnetisation PLUS the flux of the neo which is passing through (which would explain why so less efficiency).

Thus, I wouldn't be surprised if you would find similar result without an ordinary magnet but just a steel bar instead; at least you wouldn't have to overcome the flux of the ordinary magnet.

I think what you say may be the case Didier.

the concept is something Robert Murray Smith shared. After I posted the video demo he said he would do the power calculations to see if it's worth pursuing. Waiting for his results to further tests.
