Magnetic Shielding

[CLaNZeR]

Has anyone played with shielding materials such as MetGlas?

Looking here http://www.lessemf.com/faq-shie.html#Lead-Copper they quote the following:

Here's how the permeabilities of some common materials compare:

Air ........... 1
Copper ...... 1
Aluminum ... 1
Tin ............. 1
Lead .......... 1

Nickel .................. 100
Commercial Iron ... 200
Stainless Steel ....... 200
MagnetShield ........ 4000

Magnetic Shielding Alloys* ....... 20,000+
Annealed MetGlas ................. 1,000,000

No replies on this one, so have ordered 10ft length to see if it will get over the sticky point.

Will post the results.

Could you give us an example of where exactly on a magnetic motor would you be placing this insulating material? Where exactly is the spot that you are trying to insulate?

I look forward to hearing your results.

The easiest way is to look at simple wheel designs such as this that show shielding

Not saying it will work, but the logic is there.

Ever consider building some Halbach arrays to put on the rotor? They amplify their magnetism on one side and cancle it on the other. It could *perhaps* help with these sticky points.
