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

I really wonder if you can use a lema in any scheme that has magnets on the rotor. Basically the shielding takes effect blocks off the magnets in the lema and then the rotor magnets are simply attracted to the shielding and you are back where you started- sticky point.

That is what I think Sean McCarthy is trying to say in the following posts. He seems to think that there would not be an energy gain at all.

Hi Folks,

I know that a lot of people have been asking if LEMA part of our OU technology and if not what is it and why did we design it?

The answer is no, it is not part of the OU technology. As previously stated we have developed several anti-counterfeit technologies in the past, these technologies where developed for a client FraudHalt (you can see a quick overview of the technologies at http://www.fraudhalt.com/demos/)

As you can see both of these technologies have a very heavy optics involvement. Anyone who works with optics will know that you typically build prototypes on an optical bench.

So? Well optical benches use magnetic clamps - these type of clamp are turned on and off by moving a shield in front of the clamping magnet. LEMA was a concept to help reduce the force that the person using the clamp has to apply in the camping/unclamping of these types of devices.

Thanks,

Sean


Hi bobcat,

Lets take an objective view of LEMA. It is in essence designed to reduce the force required to actuate a magnetic field (as noted above). However it is interesting to take an energy view of what is happening.

Assume the LEMA unit is standing upright. If you remove the top magnet and move the shield up and down (excluding friction) you will get a net zero energy balance. Why? Because the energy you put into moving the shield up will be regained when the shield is pulled back into its original position. Adding the second magnet does not change the net zero energy sum, just the level of forces (and hence energy) involved.

So in a friction free world you have the ability to create a machine with a LEMA type device that gives you a fluctuating magnetic field for no energy. So if LEMA can be used to develop an OU device then you need to be able to harness this field without substantially changing the net energy profile of LEMA.

Thanks,

Sean


Hi bobcat,

The key issue is what is the energy equation when you switch the shield in the presence of another magnetic field? The best thing to do would be to test this
(a force meter would be required). I think that you will find that the net energy equation for such a system will sum to zero.

Thanks,

Sean

i've read that message vorlorn, but the issue is, without a LEMA, there's nothing else to seperate an attempt at creating a stoern deice from any other number of failed permanent magnet machines here on this forum...

THere's no use in replicating it if there's not something to distinguish it... not saying that they are using LEMA, but if we dont have that, then we dont have anything, just someone claiming that they've gotten it to work..

Hi,

@Thevorlorn, I agree with Kent, and may I add that there is no use pondering on whether Seorn uses LEMA or not, or whatever they say on that.
Don't forget that allcanadian already experienced in practice that the shield can be moved using very little force so this the first crucial fact we can base on.
Steorn probably uses indeed another tecnology that does not include LEMA and it is even more revolutionary,,,  we shall hopefully learn sooner or later.
All we can do now is continue tinkering and discussing the experiences.

If you do replicate the LEMA I hope that it does indeed allow for an overunity device despite Sean McCarthy's claims. I honestly would like to see an attempt.

As I mentioned before, Steorn did not claim that the LEMA was not part of the OU device until recently.  Also, in Sean's posts from this same time period, he stated that they felt they would have a lot of competition.

IF the device used a special trajectory - they could patent the trajectory path (shape), but they applied for a patnet on the LEMA.

BTW - The device does not have to be "radial" - it can be "axial" and still work.
