Howard Johnson Replication Tube Claim

[Low-Q]

I simulated those magnets in Femm. There isn't more force in one direction than the other. I compared the forces withing a given resolution, and they are pretty much the same on each side, so no net force is left to rotate the wheel. Of course this is supported my conventional physics, and simulations in a condescending software that is made only to irritate magnet motor believers. But nevertheless, the result isn't very positive.

   I have to ask how you set up the magnets. I can gather the rotor mags are one pole to the back spine and another to the two forward facing pieces. Then there is the part that he had the other horseshoe redone. I haven't figured out the exact layout of that one. I even asked him that direct and he bypassed the question. There is really not that many ways the mags can be done so will have to try all of them.

Go by the sketch - "Mylow's Sketch". Just keep in mind he draws fields in the unpolluted way. Meaning, fields without the deformation by iron filings.
IMO Mylow has been at this quite a while.

I haven't found a reason to trust FEMM for a while now. Too often it doesn't line up with reality.

Has some similarity to Corel castle ... wonder if the math's are similar.  I do not have the time right now to do the math based on code144 dot com.

Anybody’s guess which one on page 7 of http://www.arnoldmagnetics.com/products/alnico/pdf/sacatrev.pdf would be the closest to Mylow’s rotor magnets? Any ideas about the stator magnet?
