Steorn Low Energy Actuator

[Craigy]

Now have a nice stainless steel shield installed and what i noticed above is still valid although it self centres regardless of how the magnets are installed. BUT , the force required to move the shield away from the magnets seems less when the actuator has like poles facing upwards.

Was the shield stainless previously?

Hi there,

no i was using a bit of ali to mount things on, one cent coins and the like. I now have stainless steel
Anyway there was a flaw in my replication, i'm not too proud to say..The magnets when placed directly in contact with the steel linear bearing effectively combine to form a horse shoe magnet thus cancelling all flux acting on the bearing itself.
What i did, was to make a nice brass plate with magnet holders on it..(Yes a bit of a plonker i know) thus the magnets were attracting the runner to the center. This was easy to fix, i just dilled holes through the brass plate so that the magnets are in contact with the steel. Now i can test the thing

Still, who wants to patent a self centering device LOL....

Nice video Craigy,
would be nice to see it set up with a solonoid triggered by your motor disc.
