Steorn Low Energy Actuator

[Craigy]

Hi All
I would love to have more info regarding the Steorn stuff, so that i could start building one. But I there are lots of variables still.

1. 4 Magnets on the rotor, (Perhaps of ferrite)
2. One stator, neo

and as far as i know, nothing moves except the rotor which is driven externally.

The only info i am sure about is the Low Energy actuator, since the patent is avalible to view. So in an effort to try and get into the mind set of the Steorn Guys. I am replicating one of their Low energy actuators.

Perhaps after finishing this i will understand what the steorn guys are doing better, and maybe be a bit closer to what they are doing.

A pic is below of my low energy actuator, shield not yet installed but it moves nicely on its bearing so far

Hey Craigy...Did you catch any of the forum drama at steorn's forum last night?

Hi Craigy,

Sorry to speak yet without practical test but I think that a third cylinder magnet of the same size and pole's direction like the other two would make the movement of the shield even easier that the the present two,  because then the shield could always move inside a 'more uniform' number of fluxlines than in the case of only two magnets.  And then the shield would always 'receive'  flux from two and not one magnet at a time  so its movement would be smoother being always in the majority of fluxlines. (of course the length of the shield should be as long as the covering distance between any two magnets.)
If you find this third magnet as redundant because of you have already tested it with two and settled for it, then sorry for my rambling.

Hi all. What happened on the Steorn Forum?

And to answer the other question, Yes, it works just fine with 2 magnets,

Interestingly tho..if we put 2 magnets with one pole n and the other s uppermost, the linear bearing they are on returns the magnets to the centre of the linear bearing, almost like a self centering device.

Putting magnets of the same polarity together makes that disappear, and the magnets are free to slide along the linear bearing with no apparant force being felt.

I am having trouble bending the shield, it bends , but getting it to bend at the right place is a pain in the butt. So will make it out of ali and stick shield to the ali instead..

Basically, some of the members were hot on the trail of pinning down the principle behind the effect of Steorn's device, WITH the help of Sean (Steorn CEO).  He was dropping hints like it was Christmas!  THEN...he deletes like 4 or 5 threads with like 1000s of posts and tons of related info.  Someone got a little too close maybe?  You kind of had to be there. These threads were getting more posts in an hour than OU.com might see in a week.  So if you didn't follow it right up until it got deleted, you missed the boat.  I was probably on it for 9-10 hours straight.  It was such an "event" amongst the Steorn crew they were ready to make tshirts.
