The Steorn Permanent Magnet Motor Replication Project: It's FLUX time.

I think if we're going to do this we should get a small list of design ideas and try them independently.

I'm trying to understand exactly what the LEMA is doing. It would have been nice if the patents included a quick video or diagram of the rotor in relation to the magnets and shield of the LEMA.

Basically, we all know to get past the sticky spot in a magnetic motor you either have to do something not yet discovered (or discovered and suppressed) to get the rotor past that spot or you have to use some type of shielding. So the function of the shield to block one of the magnets is logical. However, what I don't understand is how this setup is creating the magnetic rail to slide so easily back and fourth. What is going on with that? Let me ask a few questions.

1) When used to power a rotor is the rail supposed to be bolted down or the the shield and base of the LEMA? What I'm trying to ask is what exactly moves and what stays still.

2) Everyone is saying the LEMA is used to balance magnets. That is a concept I don't yet have my mind around. What do you mean by balancing? Does this relate to making it easy (low energy) to move the shield and/or rail (which one moves by the way?) back and fourth?

3) Could someone post a simple diagram of how the LEMA would position itself next to a rotor?

Thanks for any help you can provide.

Perhaps Steorn has two major inventions. The LEMA and whatever technology they are using now that has nothing to do with the LEMA.

sure....

1. Really either part can move, the shield can move up, or the magnet can move down, 6 one half a dozen the other..

2. The idea of balancing magnets gets back to this 1 point.  The flux needs to remain constant, if the flux decreases then the magnetic attraction between the shield and the magnet become stronger, (The balancing is done like this) Imagine the shield in the off position, (Shield positioned to cover hte top magnet), now move it 1/4th to the 'on' position, the shield would cover 3/4's of one magnet and 1/4th the other, flux hasn't changed, shield moves smoothly.  This process can continue, imagine the shield covering half of each magnet, flux still hasn't changed, the shield can move easily)

The basic idea is that the lema allows you to do the effect of moving the magnet from 1 position to the other (its a seperate magnet, but the field strenght is equal) without the difficulty of overcoming magnetic attraction in the process...

3.  I'll try to draw something up for you very soon.

I really do not care about steorns design, He "borrowed" it from someone else,that's how evolution and invention works. Im not sure your getting this at all,read steorns patent, if you actually read it- on page 8 section 0030 it reads as follows-
"The drive mechanism(not shown)for the shield is provided by an external force such as a solenoid,linear motor or the like"

I have the patent right in front of me if you want to understand what he is doing?
