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

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?

That is in reference to the replication attempts and not to the Orbo.  How can it be another key when it's not in regards to the Orbo?

The rotor magents SHOULD NOT induce a NET EMF in the toroid.  If it does, then you would have a CEMF and that is what Steorn was showing in the replication attempts.

The polarity of the rotor magnets did not change, so why would the EMF induced by the rotor magnets be in a different direction.

Here's how to properly tune the Orbo.

1)  Dual magnets must be perfectly centered with the toroid.  If not, then you have a CEMF.

2)  Dual magnets must be equal in strength.  If not, then you have a CEMF.

3)  Dual magnets must have the appropriate distance from the coil when at TDC.  If not, then you have a CEMF.

4)  Dual magnets must have the appropriate gap between the upper and lower magnets.  If not, then you have a CEMF.

5)  All of the dual magnets must be aligned perfectly at TDC with each of the cores.  If one set is slightly off, then you'll have a CEMF.

5)  Rotor must not have a wobble and must be perfectly balanced.  If not, then you have a CEMF.

6)  The core must have low coercivity and low remenance.  If not then you have a CEMF.

6)  A tape wound core can be beneficial in eliminating the CEMF.

7)  Namlite coating can reduce the power loss from 15% - 45% due to eddy currents.

8.)  Friction from the bearings and air is a form of CEMF and both should be reduced as much as possible.

If you don't have all of the above, then the voltage and current from the pulse is not going to remain constant with or without a load.

There is no mystery or hidden information.  It's all about precision.  The key is to get the CEMF as close to 0 as possible.  Sean said the Orbo must be built with hard disc drive tolerances, and for good reason.  I'm sure the list above is not a complete list.

Anyone up to the challenge?  You can have all of the expensive equipment you need, but if you don't build it with tight tolerances and with precision, then the equipment won't do you any good.

In some video way back when steorn was first on the map I recall seeing the magnetic interaction that happens with a "net gain" and it appeared that the magnetic pole was not directly parallel with the other surface it was a little higher or lower I cannot recall which but... Just an observation I wonder if the position on the magnetic field lines has a degree of importance in this "orbo interaction"?

Are you saying that many of Steorn's current traces show the same rise at the start? I thought their whole schtick was that it was perfectly flat.

Look at the two pictures in my reply 2442. The first is of the pulse motor and has a classic induction rise(outward curve) and fall(inward curve). The second picture is of the Orbo motor and is basically straight rise and fall with a very slight angle. It is chopped off in the second picture, but at the very bottom of an Orbo rise traces(reply 2530), there is a very small inward curve(zoom the picture) at the start of the pulse. But it is backward to a normal induction rise curve.

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.
