   Want to know if you are powering it too long, insert a .1 ohm and scope it. If your trace levels off at the top, you are. In this case, back the hall out a bit. Saw that used in the attraction motor secrets thread on EF.

@Neptune,

Here's the figure to explain the tolerance and fine tuning issue.

It should be self explaining.
If Rotor magnet RM1 is facing the stator coil, the optimum is tuned by Stator magnet SM1.
Then rotor rotates and rotor magnet RM2 faces the same stator coil.
But RM2 has different strength compared to RM1 (0.95T versus 1.05T).
Then the position of SM1 should be tuned again for optimum drag, which will spoil the optimization for RM1.
So only an avarage optimum position can be obtained.
If RM1 would have same value as RM2 than optimization would be perfect.

this time is related to Magnetic Domain propagation speed - domino effect ( 100 - 2000 m/s ?)

i.e. magnetic viscosity

@Wings,

I noticed you added these graphs.
Can you post the link?  I like to check this, my own observations might be to narrow minded....

After my replication of another prototype I will build the stator plate out of non ferrous metal or ceramic and encapsulate it and evacuate the air AND place it on magnetic bearing (if it is balanced enough)  Then the RPM will be targeted between 20,000- 22,000 and since the output is linear the wattage will increase 40 fold. That will give us a unit that is able to handle most our power needs.  It will be about the size of a 5 gallon propane tank and will be nearly as lite as an empty propane cylinder.   This will include an AC inverter  and regulated DC outputs also. 

Longevity in real statistics?
http://www.youtube.com/watch?v=KGrKDswHdIo This youtube states 300 years.  Degrading .93% every 10-15 years (loose data) depending on environment.

Also we realize that the hall switches will not be able to keep up at that 20K rpm so we will look toward opt relays like these:
http://www.alliedelec.com/search/productdetail.aspx?SKU=9090167



This is what a manufacture states:

Sintered Nd-Fe-B magnets will remain magnetized indefinitely. They experience a minuscule reduction in flux density over time. As long as their physical properties remain intact, neodymium magnets will likely loose less than1% of their flux density over 100 years. Generally the magnet will experience a degradation in its physical properties, such as corrosion, prior to it demagnetizing because of age. However, heat and high magnetic fields can demagnetize these magnets.

@Teslaalset .Your logic is irrefutable . What I would suggest as a starting point is this . I f you have loads of magnets on stock . Devise a simple test rig to measure the attraction force agains a piece of iron ,using a spring balance . Then pick the 8 magnets that come closest in strength . That may well reduce the need for tuning .

Or simply use the hall sensor that you need anyhow to measure relative magnet strengths.
I'll check other simple methods. I found several in the past, but I can't reproduce them right now.
I'll post them here, when I found them again.

Thanks Wings, I got it.
I'll study this, and sorry for being so bypassed. Learning all the time.
If this is feasible this will be great for solid state versions as well !!

just 2 cents

perhaps this can help

and if somebody of you can interprete  something usable in this video, please i would be very pleased

thanks

Build you're own gauss meter http://www.coolmagnetman.com/magmeter.htm

I think this would work if the magnet sat in a jig so the magnets were in the same exact spot every time.

@TEKTRON,

             Exactly, that's why I went with snug fitting diametric tubes.

@Wings,
Unfortunately this paper applies to permaloy nanowires, one can not apply these findings to ordinary ferrite I am afraid.

I looked for the comment of Winsonali and found it as well.
The 10 ms he is referring to is just 10 ms part of a 20ms pulse.
If one pulses a coil that has a non-liniar core, the core starts with a high value inductance and as soon as the core reaches saturation the core value decreases significant. This causes a large increase in current through the coil.
The current delay is caused by the coil value, not by the magnetization speed of the core materials in my view.
One can do a simple experiment to proove that.
Just put a load on the secondary of such transformer with similar core material. The current will increase much faster than in the case of a none loaded secondary. 
This is caused by the counter flux. If the core material would be 'slow' then the counter flux would be delayed and one would not see this effect.

99 % of research is in nanotech and so the paper ...

IMO the effect at our scale is effective see Energia Celeste device with in mind the last paper posted or Naudin orbo test :

Wings, I hessitate to accept that the paper that shows the magnetic lag while increasing the flux is applicable to normal ferrite cores with the time scale that is shown in the paper you refer to. I can't find any comparable results published before the 'nano' period.
I am sure this has been investigated earlier.

It's a long time since I reviewed Naudin's findings on Orbo.
I did some experiments with magnetic biasing of ferrite cores last year, so this is a kind of a dejavu.

My experiences with magnetic biasing was quite educating.
In general I found that you can 'tilt' the B-H curve by a magnetic bias (clockwise tilt looking at the B-H curve).
I did this in a stationary situation.
Tilting a B-H curve means changing the maximum coil value and changing the + and - RM level.
Translating this to moving magnets, I see that the only difference between RomeroUK's setup and a normal pulsed DC motor is the pulsed magnetic bias to the stator coils.
I need to think this through to come to a good conclusion why this would lead to energy gain, but it certainly is a gap in my experience.

my experience is much less than yours, just a reading hobby with small experiments.
I read a document in the past by Cyril Smith that speculated about OU from a cycle by BH magnetization.

now no longer found in internet and I have only one copy on paper and I will find it.

thought: in this case the ferrite core domains are aligned in some direction, direction changes do not start from random arrangements that involving more flipping energy ....

in any case more in: phase i.e. more rapid, more powerful

Energia Celeste have the pulse delay coils installed within the magnet!!

Kunel also ?
