Howard Johnson Replication Tube Claim

[lostcauses10x]

Any one seen the c magnets before??

X00013 - interesting video.  Out of the thousands of bs OU vids on the tube, this one is of unusual interest.
The 'odd' shaped magnets used may be resulting in a useful effect.

The thing about the Howard Johnson designs, like his more known motor, is the 'odd'/arced shaped magnets supposedly required to work.  Custom ordering/designing magnets to achieve the same effects as Johnson reported would be expensive and a crap shoot at getting the specs right.
As such, replications have been slim-to-none.  Anyone have any other links/examples/etc. of reproductions of Johnson's designs?

Howard Johnsons granted patent for the permanent magnet motor-
US Patent # :  4,151,431  April, 1979

Anything I've ever read on this design state it as unworkable....
But the ideas presented in the patent and the youtube video link you gave don't seem IMPOSSIBLE.

Anyone willing to do some FEMM simulations and post them/pics?

Thanks for the link OC

Alnico magnets are relatively easily to be demagnetized and are relatively low gauss.

The coercive force of AlNiCo magnets is very low , so it can be easily affected by reverse magnetic force, and/or impact. This means that they can be easily demagnetized by external influences.
'AlNiCo magnets should not be stored and packed with the same poles opposing each other.'

In the video, he states his stator magnet became demagnetized.  Must be an alnico magnet as well and will probably see it continuing to demagnetize unless he changes the material of that magnet.

Any sources for these rotor shaped magnets in something like N42 rare earth etc?
The stator magnet could be something like this?

Hello Paul -

Yes - it's probably - what - 99% chance it's not legit? (100% so far!) 
But it's just about the only one I've ever seen over the years that I wasn't able to fairly quickly say it was 100% chance of bs.   
(and I've always thought Howard Johnson had some interesting ideas)

Watched/listened again....

I hear a 'motor' noise you may be referring to.  However, I also hear a car horn and traffic noises, so it may be vehicle noise?

At 1:32 you hear what sounds like an electric motor powering up.  Or could be a car/motorcycle?
And then he talks....
Again at 2:23 the 'motor noise' and shortly after it starts to spin.
But while its spinning there is no motor noise.
At 2:51 there is a car horn.
Most the video of it spinning there doesn't appear to be 'motor noise'
But the sound at 2:23 IS/COULD BE suspicious?
But the lack of 'motor noise' for most of the video/spinning/start-up could be an indication the other sounds are background sounds?
(Certainly a better video with a larger view the whole time would be of benefit!)

What do you think?
