        And let me tell you my vision of the processes in Mike Corbin's device .

                           Since the Director is made of a material with high magnetic permeability, its rotation changes the force of interaction between the two compound rotor magnets. Everyone is well aware that when two magnets approach with opposite poles, they turn into one magnet. There is also a reverse process. At the same time, the strength of the poles of these magnets changes to a large extent.There are also many intermediate positions.
                                                  Thus, the rotation of the director in the center of the rotor significantly changes the strength of the magnetic field at the two ends of the rotor.
                                           
                                          I want to see the continuation of this story, otherwise I'm bored alone writing fairy tales .....      

Hi BorisKrabow,
Refer to reply #233. Image attached below for convenience.

This shows the flux in the outer gaps remaining the same as center director is displaced. I suspect that there would actually be some distortion of the field in the magnet/stator tooth air gap because the overall circuit reluctance changes and because the rotor magnet will displace relative to the stator tooth (which is not obvious in the FEMM). I think a more detailed analysis is in order. The rotor does move from tooth to tooth, so there is more to it. This is a first step, and nicely done.

Previously, a member commented he didn't see how torque on the director could cause the rotor to move past the stator tooth (stable detent). With equal distance and area gaps, that may well be the case. This FEMM supports that. My contention, since there is actual rotation, that there is another factor at play, for instance, the outer air gaps made longer than inner gaps at the director.

Also, in regards to your remark about breaking a magnet in half, good thought process. I suggest you take it a step further. I'll post a link to a pull force calculator. Run through a simple quick exercise. Choose a material, diameter, thickness, etc and find the force. Repeat with everything the same except half the thickness. How does resultant force compare?

Hi!
                   For me, this is big news. I did not know that everyone here believes in simulations. Apparently no one now measures magnetic fields with instruments. This model, like many others, does not even closely show the ongoing processes.
     
But that's not a problem, just copy the device like Mike Corbin suggests and you'll be fine.

Hi BorisKrabow,

Of course there are a number of ways to develop the Corbin patent and just copying the device
is probably one of them. The problem is; it's quite difficult to simply copy the device - not enough
information is given in the patent or on the web side pages (at least I can't find enough there to
even attempt a "just copy the device" starting point.

However, I never approach a design from that prospective anyway since its too expensive, time
consuming and risk prone. A good professional CAE Analysis and Simulation is much less risky IMHO.

So anyway, I have taken the concept and began developing it using Solidworks EMworks 3D CAE
simulator and so far found considerable merrit in Corbin's concepts; this includes reviewing the
simulated torques and forces for the various elements, including different types of magnets, thru
it's various operational angles and interactions.

Still a work-in-progress but it appears, initially at least, the invention is viable and will function close
to what is claimed. Since the device is relatively simple and I have a modern CNC machine shop,
a replication will likely be attempted (after the in-process Holcomb LinGen and, next-in-que, Perendev
designs are finished).

Note that I don't find any good reasons to publish much on the open forums anymore for obvious
reasons... however I'll keep the group informed as things progress [but it won't be anywhere near as
detailed as the LinGen was].

Hi!   This video is from another thread, this device showed the reversal of Lenz's Law.
  https://www.youtube.com/watch?v=ANXhrdRNrss              but even here it is clear that the stronger the magnets interact, the weaker the middle and the stronger the field at the ends. This happens until the two magnets merge into one magnet. And this composite magnet has a field in the center equal to Zero.

          Perhaps I am far away and cut off from the generally accepted opinion, but it is already doubtful to draw lines of force through a magnetically hard material on a par with a magnetically soft material.

         here another strange phenomenon can occur, at a certain percentage of interaction between the magnets, a rapid restructuring of the properties of the magnets can occur. In this case, the connection between the rotor and the stator can be momentarily lost . There are many such little-studied phenomena and it is impossible to model them.

              first you need to model without a stator, the overall picture and understanding will be clearer.

          From all that I have said, a simple conclusion is that we need an exact replication of this device.
        These are not all phenomena, I will leave a couple of surprises for myself for now ........
