Magnet Motor from Argentina, part2

This is what comes of trying to make the torbay work, in the end i have run out of options and i will have to change the confguration of the torbay. i cannot see how torbay's design could possibly work as published.

I still have a few ideas , but i must leave the standard torbay configuration behind and embark on my own designs.

Here is yet another video of my experiments

I hope these videos help people to design their own machines learning from my mistakes

I would avoid using aluminum as the shield material. I have been told that dragging a magnets field over aluminum will create eddy curents. I'm not sure wether this applies to your thin shields but I figured I would at least put it out there for someone with more knowledge to comment on. Plus I'd hate to see you start cutting them only to find out they belong in the same pile as the sheet metal shields.

Good luck and good work,

Just a thought ... Stainless Steel 316L can be heated to a point that it is annealed and removes any magnetic flux ... not sure if that helps.

Dragging magnets over any metal with non-zero conductivity creates eddy currents in metal. This is one of the ways of shielding.

Hi guys, i do not expect aluminum to do any real shielding as such, but i can use the mechanism to experiment a little with different materials, as mentioned in the video, for example different coins or metals etc.
But the design is flawed in so much as i have been trying to replicate the torbay, so the thing was made with a replication of the torbay in mind. Trying to add shields at this point is not ideal.

I will construct another motor which i hope will address the shield problem much better. This time i have designed the motor with shields from the outset, thus it should not suffer like the one in the video with problems in attraction.

I am awaiting parts , but i will try building a 8 horizontal shields.( Useing mumetal hard disk drive shield) The magnets would be fixed into the base and the rotor magnets would have their flux directed down over the fixed stator magnets in the base board.  The shields attached to linear bearings would then slide in from the side , horizontally. Thus i hope that when a shield is not in use it would have no effect on the rotor, so the rotor maintains its torque..
We Shall see..
