STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

@LarryC,

            Let's not forget that the trace comparison between Steorn and JLN involves two different planes of approach. The Steorn trace was produced by magnets swinging by the toroid from one side to the other in a parabola as the the rotor spun by, while the JLN trace was produced simply by pulling the toroid straight away from the magnets in linear fashion. JLN's tutorial is merely a teaching tool to help us understand how the Orbo can generate power to help run itself without slowing itself down.

This is correct and there is a Big difference between the two.  It's like trying to compare apples to oranges.  Also, in the Orbo, the coil is open while the magnets are approaching the core......so there can be no EMF induced in the coils during the approach.

@LarryC:

Sean said the Orbo has no CEMF, did he not say this?  If it has no CEMF, then the rotor magnets are not inducing a NET EMF in the toroid coils that is in opposition to the EMF of the pulse, is this correct?

If what you are saying is correct about the rotor magnets inducing a NET EMF in the toroid coils, then Sean is not telling the truth.  I haven't had time to re-watch the "replication attempt video" in reference to the time periods you have mentioned.  Either you are misunderstanding something, or Sean is contracting himself.

If you can get the CEMF to near 0 by following the list I previously posted and assuming we have the proper core material then our cores will behave like the cores in the Orbo.

Let me watch the replication video again.  I have a feeling it has something to do with the air gun.

I also believe that Steorn is talking about Net CEMF.
The two magnets pass by in a symmetrical orientation.
Each one will cause local dipoles to move. Moving dipoles will cause current in the coil.
The movement of the dipoles in the coil is different at each location of the core, but due to the symmetry of the magnetic field, the net effect is zero.

A few facts:

Although I believe Steorn has a legit "free energy" machine, they're (Sean) is wrong about no CEMF. The reason Sean believes this is because he takes inductance measurements with and without magnet, and they're both basically the same, ultra high inductance. What Sean is obviously not considering is that such inductance meters do not saturate the core. Saturation of the core is required in order to noticeably decrease the pull between the magnet and core. This is not referring to the cores normal saturation from coercivity. We're talking about extreme saturation. When the core is saturated as such, the inductance is low, micro henries. That is why Sean believes there's no CEMF, because the scope shows a square wave, rather than a typical RL curve, because he's expecting an RL curve from a 0.98 henry inductor!!  If you look closely, you can clearly see the Orbo RL curve in their scope shots when they zoom the scopes time domain. In fact, one could even calculate the inductance of their cores.

As far as BEMF, the reasons there's no BEMF is because it's a permeability motor, and requires a completely different analysis of *changes* in permeability. So saying there's no induced voltage from the spinning magnet with no current through the coil is meaningless in this design.

No BEMF because it's a permeability motor?  Lol 

It's a "Pulsed DC Permanent Magnet Switched Reluctance Electric Motor".  Did I say that correctly, lol.  It's a variation of a switched reluctance motor (SRM), http://en.wikipedia.org/wiki/Switched_reluctance_motor

BEMF is when the field collapses and cuts the wires (The "B" is for the EMF coming Back to the source).  CEMF is the EMF that is induced by the rotating magnets that is in opposition to the EMF of the pulse (The "C" is for a Counter EMF that is in opposition to the applied EMF). 

If you have a CEMF from the magnets, then it will be in opposition to the EMF of the pulse and the voltage will drop and the current will decrease over time, thus you get the curve over time, unlike in the Orbo.  The Orbo doesn't have this curve because it has no CEMF.  There is no mystery in this.  It's a really simple concept.

I wouldn't say the CEMF is 0 in the Orbo, I would say it is near 0 in the Orbo, thus you have to zoom in on the time domain in order to see it.  The CEMF in the Orbo is so tiny that it is irrelevant and if you rounded it off then it would be rounded down to 0.  It really amazes me how things are always being taken out of context.  The CEMF in the Orbo is close enough to 0 to be said to have no CEMF.  Reduce the CEMF to near 0 and we can have a scope trace like the Orbo.

I don't know, but there are many Steorn traces that show a similar trace.

In the Steorn video 'Steorn examine Orbo replication attempts' they showed that opposite polarity magnets on the rotor will induce emf in the same direction when current (+ or -) is applied. Another, how is that possible? I'm sure this is another important key, any ideas?

Regards, Larry

If they had of left on voltage you would see one signal was lost due to the inductor filtering it out.
Input signals were exceedingly different due to offset magnets and coils.

If a moving magnetic field crosses a conductor CEMF exists. It does not have to have an existing current.
