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

These are normal ferrite core coils as you can see from the high resolution pictures
posted.

The function is this:

If the ferrite coils are not energized, the magnets in the rotor attract the
stator ferrite cores of the coils.
the rotor is accelerated into the direction of the ferrite cores.

At the time the rotor magnets reach the ferrite cores of the stator coils,
the coils are energized for a few milliseconds, so the ferrite cores
get saturated and their muR=1 then, so these ferrite cores act then,
as if they would be air and thus the rotor magnets don´t see any
ferrite anymore and can rotate freely on.
Then the coils are switched off and the rotor magnets again attract the ferrite
from the next position and so the rotor can rotate on and gets accelerated
and produces torque.

Now to scale this effect up,it only needs bigger and stronger rotor magnets
and optimized toroidal ferrite core coils,where the inputted energy can be recycled.

If you go for about 1/5 tau=LR only switchon time,
you will almost have no ohmical losses in these coils and can
recycle about 90 % of the inputed energy via BackEMF extraction.

( Please remember the difference between BackEMF and CounterEMF !
This motor does not have CounterEMF. But it does have BackEMF,
which is the same like flyback coils, who generate a voltage spike,
when they are switched off. BackEMF comes from the stored magnetic
energy of the coil and core and can be recycled, which is also the case over here.

CounterEMF is the normal induction for instance in a normal DC motor,
where the movement of the coils in a magnet field are inducing a counter voltage versus
the driving voltage, so the total driving voltage is always less than the inputted
supply voltage. In the Orbo motor we don´t have such a CounterEMF !)

So with an optimized design with BackEMF recycling you only need about 10% energy input
of what Steorn has shown now and can get the same torquexRPM= output power
out of i

Hello Stephan, good to see that you are finding merit in Steorn's shown device.


You are still way off the mark, and that's because of non obvious things, but you are in the right track.

Cheeers!

Well done !
I guess now we know the real effect behind
the Steorn Orbo demo.

Tinsel Koala does not agree,
but his 4 new videos do show a totally different motor,
which I must have a closer look at still first .

He is using just aircore coils and seems to have simular CounterEMF -less
behaviour...

I agree with you Stefan, TK is mixing apples and oranges and trying to prove they are the same. An air core PM motor does NOT a shielding device make (Adams Motor).  A air core motor can be made to be low CEMF and have BEMF or Inductive kickback with funky coil design as shown, same thing, but that is all. it will not be OU.   He is an excellent experimenter, usually dead on, and I have watched his work for a long time but I think he is missing the point on this design.  I have built both kinds of motors, looked at waveforms till I was blue in the face but never latched onto the toroidal coil design!  I give Stoern credit for that!!!!!  Absolutely cool!!!!!

For any moderate builder this motor is very easy to build. It might be even easier to modify and existing bedini motor.
