@ all readers

Request ...

I realize that over sized pics. are         some times      needed for clarity, but
other wise...

Would you stop blowing up the topics with over sized pics, that cause readers
to have to scroll back and forth to read the texts / view the pic..

Re size the pictures in paint or another program before you upload them
please ?  Check to see that the pics. are not over sized before the time allotted to
edit the post expires.

Also edit texts, so that they do not extend beyond the screen edges.

One more thing...
             Please don't throw cigarette buts in the urinal.
                It makes them soggy and hard to light !

Very interesting all. Thanks for the brain food. But let me ask this to perhaps save myself a build or convince myself to do it.

What is the point of the reciprocation magnets.? From my understanding, the power is being produced from the flipping of the propellers.

Let's assume we are using a kundel motor with one pair of propellers. And let's also assume an electromagnet replaced the reciprocator magnet. In this assumption, the electromagnet is much stronger than the reciprocator magnets currently are. And let's also say the electromagnet took less wattage to power than the voice coil.

Wouldn't it be more advantageous to replace the reciprocator magnet with an electromagnet. So we eliminate reciprocation altogether and also eliminate opposing force on the reciprocator?

Or am I missing something? Is there really a purpose in the reciprocation itself, besides obviously getting a magnet close enough to flip the propeller?

              The first electric motors were reciprocating. 

Things which were learned from these motors led to
the  innovation which was rotating motors,
                          and
which increased motor efficiency due to their conservation of momentum.

                   "the power is being produced from the flipping of the propellers "

That is true of conventional motors (not induction motors per say) as well.

So what is different about the Kundel ?
... ... ...
For one thing...

There exists a kind of right angle interaction of the magnetic forces, that does
not exist in "conventional" electric motors.

Right angle interactions can in some conditions double (or more) the force and
energy available, over what is arrived at through direct / non shearing interactions.

How exactly to take advantage of this fact is perhaps, the essence of these
investigations.

  good questions !

Mounting this spool inside the ceramic collar bearing, attaching the Arc segments and fixing the diametric piston in solid position should deliver the OU COP.


We can cut the spool in the middle and glue the ends together inside the collar bearing to help strengthen the body of the spoo


A 3d printed pillow caseing for the collar bearing would attach securely to the base.


Floor,

I hope you don't mind that some of my explanations
are beginner level.   I consider my self a beginner.

Sure
next level / electromagnets and so on.

If you're a beginner, I am still in the womb..

I'll be the first to admit-  I've been wrong more times than I've been right...  As I see it,  it matters little..  What matters is having a mind that can comprehend logic, and the determination to follow through.

Attaching 4 Arc Magnets to the spool walls Kundel polarity with a fixed diametric piston will mirror the Kundel arrangement.

Axial polarized arcs like that are hard to find. Trust me, I looked.  Aliexpress had 1 seller, that had them but the price was unreasonable..

I did order 48 arcs that are polarized on each end .  But if I make a circle with them, the best I can do is have -+-+ in 1 full rotation.  Instead of flipping the actuator polarity twice per revolution, I would have flip the polarity 4 times per revolution.  Which means I would have to have a minimum of 2 bipolar hall sensors.. (one at 90 degrees, one at 180 degrees)..   This is definitely doable, and I'd imagine it would increase the torque by double.

Alternatively I can configure the same arcs +-+-+-+- which would need 8 polarity switches per rotation. 45, 90, 135, and 180. 

This scares me, as my scalp is already sore from all the head-scratching dealing with a 2 polarity propeller. Lol

I also have diametric rings coming.. 

So yea, I am not done here yet!  I plan to finish tweaking this one out and trying a simple electromagnet design to compare.

Sawing 2 axially polarized ring magnets in half would create 4 arc segments.

Jerry Bayles demonstrates the spiraling field expansion of spinning magnets. The magnetic fields inside this Kundel Coupling actually grow stronger as the gear accelerates. This accounts for the increased load with reduced input. The magnified field strength remains recessed unnoticed in the background until put to work on a load.

It kills me buying expensive magnets and taking a grinder to them.  I tried with one nice thick ring-magnet last week.  I cut slowly and kept misting every few seconds to keep it cool.  It worked, but I am still not thrilled by the idea of chomping into several of them..

I will be receiving 40 of these 90 degree arcs in the mail soon.  They are small and polarized wrong, but I could use several deep per ring to make it nice and thick.  I will have to have a minimum of 4 poles tho in the ring using these, so the hall sensors and timing circuit will need to change.

I figured if I can't get them to work good for propellers, I can always use them to make a generator for the rig.

This design has two axles and two bearings. The spool can act as a single axle with one collar bearing. 2 Kundel spools could power a car with the linear oscillator attached to a drag wheel mounted in the center. They could power a Cyclo Copter the same way.

Sketch. You would have to plug in and discharge this car after a trip!

I made a simple prototype of the Kundel idea with an electromagnet and have some results to share.  The electromagnet kundel will be operating pretty much like your pic.  2 axles when I do the next model..  The results are good enough to convince me to do a proper build.

I will start a new thread for that machine- and keep this thread for updates to the original kundel..
