Magnet motor in Argentina

[Omnibus]

Thanks a lot, tao. I wonder if I understand it correctly? The net force would exist if the calculated lines of force of the rotor magnets do not appear symmetrical and will be in the direction of narrowing the distance between these lines. If that?s the case, obviously magnetmotor11.ans (whereby the circle of stator magnets is closed) won?t provide a net force ? picture seems symmetric. Not so in magnetmotor12.ans (with a gap in the stator) ? the lines, although frugal in my picture, are clearly non-symmetric and appear to get closer towards the gap.

Could you please make a graph of the same disposition of the three rotor magnets but with flat surfaces (flat surfaces of the stator magnets too)? Thanks.

The rest of the pictures don?t seem to show anything as unusual as magnetmotor12.ans  as far as I can see.

tao, forgot to mention this -- I fully agree with what you said about eMachieShop. Initially I thought it was expensive but maybe you're right, this might be the most convenient way for a project like this. Indeed, eMachineShop is one of a kind.

If you guys gimme autocad drawings i can make an acrylic prototype. I work in a machine shop making acrylic manifolds. The  maximum size has to be 6x10 inches. Try to keep dimensions in inches. Also if you keep the drawings separated like broken down in to pieces the better. I can make them in my lunch break if they are short programs.

Here are my new FEMM files as an attachment.
Now as the server again has a new bandwidth for the new
day and I moved away the huge videofiles from hotlinking and
draining my bandwidth, now I can also download the other files.
Many thanks for the Bryce file, will download them now.

Who has already played with Lua scripting and can do an
simulation animation with the right magnet sequence ?

It seems a circular magnet with normal South-North magnetisation
through its diameter really has the most useful torque.
I will post at the weekend the screen shots of these FEMM files,
I still have to compress them some more, have to download a good picture
editing program to this new PC I am using right now.

just an idea but why dont we design molds to be made by emachineshop instead of actual peices.... this way we can reproduce the parts as needed and save some money since most of the parts on this device repeat themselves.

also the more i look at this device (peice by peice) the more detail i see being needed... and the less likely i see myself "rednecking" a prototype. I will continue to try but will be glad to assist in a group effort as well.

I am not sure how I can help so just let me know.

I have over two hundred old hard drives that are only 170- 500 MB so useless. I am taking them apart right now if anybody wants some of the parts (disks, motor, magnets, case) just email me and I'd be glad to share.

I am trying to find a magnet that is "polorised through its center" as mentioned before because i think this could work as well in the rotor. does anyone know of a disk magnet that meets the criteria? exp. speaker magnet?

and has anyone figured out if we can leave the magnets uncut? if we can't then does anyone know what cuts to make for this device? I don't quite understand how this part works.
