Howard Johnson Replication Tube Claim

[gyulasun]

He confirmed that the stator magnet is an iron-based magnet, not alnico.  He said he also got it from the Science & Surplus store, but it was 10-15 years ago.  He said it looks like it's been molded into its arc shape.  He said he has had it re-magnetized twice now, and that it costs around $60 each time he does it.  He said he'd get me the address of the company that does this for him.

He noted that the magnet is yet weaker today, and the rotor is spinning slower today than it was last night.  He estimated that it loses about 1/2 rpm every hour or two.

Hi Sterling,

Perhaps he (Mylow) could make another stator magnet from an U shaped soft iron piece with two Neo block magnets attached to the prongs and test his setup.  This would not make any harm on his present working setup and he could change the distance of the stator magnet assembly the same way like now.
Of course the size of the U shape iron piece and that of the Neo magnets may need some tinkering to arrive at a size where the rotor can maintain its rotation again.

This substitute stator magnet assembly may show more magnet strength stability on the long run (Neo magnets much more durable than ceramic or AlNiCo types, not to mention old steel or iron magnets.

Something that has crossed my mind is how Howard was able to to get those magnets with small enough tolerances, so his perfectly calculated shapes and orders of the magnets made this motor working.

Howard's educational progress is clearly evident in the later, linear patent model.  It seems plausible to me that his work was stifled a bit, by whom and for what purpose is arguably considerable.  I feel that, should he have taken a slightly different path in his research, he would have made quite a leap in realized efficiency.

The funny thing about magnets is that although they can stand being alone, they prefer having close company so they can truly be as one.  As we all know, familiarity breeds contempt, so then the question becomes how to make a friend's comings and goings of benefit to all.....an interesting guest should be able to make frequent visits and still never wear out it's welcome, by sticking around to long.

I'll ask Mylow if he thinks this site magets will work.

you know I never miss a good party 

CLaNZeR!  Sean, glad to see you - I went to your website last night looking for an email address for you (to no avail) hoping to spark your interest in replication - seeing as you are one of THE PREMIER replicators around!  What say you?

Thanks Alan for posting all that info at peswiki,  Having an uncluttered listing of the relevant info is great!
The fact that you are interested is a great asset.

I would think a critical aspect would be the magnet spacing:
The rotor magnets need to be spaced relative to the spacing between the N/S faces of the u-shaped stator magnet.
So if using different magnets, one should keep that spacing relative.

I simulated those magnets in Femm.

Would you care to post pics/.jpgs of your FEMM simulations please?

sterlinga, I don't want to start another war here but I must note that your statement: "as in energy coming from nowhere; the energy is coming from somewhere" is unfounded if you mean that there is some preexisting energy reservoir which is being tapped to turn the motor. There is not a shred of evidence to support that.

On the contrary, there is all the evidence, and it has been proven beyond doubt, that in these machines energy which turns the rotor does not come from a pre-existing energy reservoir. Here's how it works: Proper construction of the motor allows for the magnetic force to induce displacement. Pre-existing magnetic force is not energy, neither is the displacement alone.
Force over distance is. No pre-existing energy reservoir and yet there's energy which drives the rotor.

In convention science it's customer to provide a reference containing the proof. Otherwise it's just a meaningless claim.
