Question for Bruce
« Reply #60 on: March 25, 2010, 05:40:01 AM »
Bruce, did they give you any info on the exact type of black iron oxide they sold you?
I believe there are 3 maybe 4 different compositions.
Thanks so much for the test. Thats a lot of resistance.

the problem is quite congruent, if you are not using superconductive material then you will have losses. simple as that!

This is really a great new design.
I guess it will be a winner
and it is a real good dragless generator.

Looking forward to see it realized in real hardware.
Don´t build it too small, so the magnetic losses
and hysteresis losses will not kill all the output.

Many thanks.

Regards, Stefan.

The Perminvar alloys have constant permeability and almost no hysteresis up to flux densities of 1,000 Gauss. Even at still higher flux densities, residual magnetization and coercive force remain practically zero.  The permeability of Perminar, however, remains constant only as long as high magnetization is avoided.  Other materials which have constant permeability are Conpernik, Isoperm, and powdered irons.  These materials have a near 0 hysteresis loss

The above information can be found on the 12th page of the "Survey, Characteristics, and Evaluation of High-Performance Magnetic Core Materials" by the United States Airforce, http://www.overunity.com/index.php?action=downloads;sa=downfile&id=381

Hi Butch,

No, simply Black Iron Oxide Powder.  It is very fine.  If I recall, there were some that were larger grain.  I tried to find the finest particulate.  I hope that helps.

Magnet spinner rotor.

 @Butch,

             I'm sure you've seen the single magnet rotor Bedini's. Lidmotor has a gang of videos on youtube. A reed switch and tiny bobbin pulse coil are real simple to assemble, and different shape and size diametrically polarized magnets are cheap and easy to come by. There are numerous examples of stationary positions, from a divot below to attractor magnets suspended overhead. Lidmotor demonstrates a levitating cylinder in his latest video. This would give you the frictionless bearing you're searching for. The power from the demagnetization provided by your ingenious stator slots should energize the two side output coils enough to loop the power back to the pulse circuit for a self runner.

Just commenting, as it may still be worth a try.  What do I know???

This still makes me go back to the original "Impossible" designs where
the flux was re-directed via spinning Mu-Metal between different
magnets for flux control.  This setup, with the magnets spinning in
a flux containment "Shroud", should be MUCH more efficient than that
and should be operable with less than 1 watt of power, with good
bearing selection, etc.  (Thinking back to RC Car racing.  Did a LOT
of work saving input power as the only requirement for the class
was the battery size.  You wanted it to die as you crossed the
finish line.  The more you saved, the more you could put into drive,
etc.  I'm sure you understand.)


Yeah, I am still trying to get my brain around this. What are the parameters
of what needs to be accomplished to apply this method? You will notice
there are very few permanent magnet alternators listed on the web.
So ok..they are harder to regulate. They would to some extent compensate
for energy density problems coming from inserting nonmagnetized metal
into the rotor area. At least the rotor of the alternator is the field.

If people have the computational resources I recommend they get access
to femm free magnetic simulation software. I am especially interested
in solid state designs but few people have the knowledge required
for injecting rotating mag fields into toroids, seeming requiring precision
control electronics at speeds near C.

It seems a mechanical vibrating arrangement like a tuning fork
might be an interesting intermediate choice between a rotating
rotor motor and absolutely stationary electronics.

@Loner

I find it amazing what people can accomplished when the rules
stay fixed... As the "impossible" designs that you talk about.
Good luck and I will be watching what you come up with
renewed interest based on the explanation of methods that you
have discussed. Thanks.

Hey folks, this is where I got mine from :http://shop.chemicalstore.com/navigation/detail.asp?MySessionID=84-264881176&CatID=28&id=FE3O4M1
Phoneboy,
Have you made a core yet with this powder using some type of resin?
If so, have you checked to see if it has any residual magnetism after you remove it from a magnetic field?
Thanks,
Butch

Thanks for the info. I would really like to eliminate the bearing drag.

Hi Butch,

I really like your new PM flux gate design.  I wish you and your team all the best with the build.

Thanks for always sharing work work.

Not yet, I'm still gearing up (tools/materials), but I don't think that would be much of an issue with your design as the fields will be alternating rapidly.  By the way congrats on your discovery, unfortuanately it side tracked me even more as I ended up modifying one of my designs as I think we could also use this to motor.

The trick is to find a ceramic bearings that are 100% ceramic (balls, race, and retainer (( I said balls, chuckle)), http://www.bearings-china.com/main-products/Ceramic-bearings.htm,  then use less than zero weight oil.

A magnet or electromagnet can be turned ON AND OFF with pretty much no NET energy consumption.

However, if you try and extract energy from this changing magnetic field you will inevitably see it reflected on the input.

The concept presented here runs into trouble when a coil is placed and loaded on one or both arms of the "switcher".  When that happens, the magnetic path of these legs has changed it's apparent AC reluctance and the flux will not prefer to "flow" that way, once that happens the magnetic fields/flux  configures itself such that the rotor will experience a torque, and if you fight that torque in order to to rotate the rotor, you're imputing energy into the system.

The software used to simulate the "switcher" should be used to simulate the WHOLE problem including the output coils under a load, and then it will become apparent why it is unfortunately NOT overunity.

So remember, a MAGNETOSTATIC simulation will only get you excited and then into trouble and wasted time when you try and extrapolate the results to a dynamic problem.
