Howard Johnson Replication Tube Claim

[sterlinga]

I spoke with Mylow and his brother (Mylowbro).

They got the motor reassembled.

We talked just after they got it running at around 8:15 pm Central time

It was spinning slowly, and slowing down.

It was spinning at 8.5 rpm (~7 sec / rotation) when we first counted the revolutions.

It ran for about 3.5 minutes before coming to a stop..

While that might not sound impressive, I asked if it accelerated when it first started, and Mylow said it did.

The deceleration was in the equilibrium speed, which diminished as the iron magnet degaussed.

Before putting the stator magnet on the stator holder, Mylow said it was so weak it would not even hold up any steel.  He said the two stator magnets wouldn't even stick to each other.

What this demonstrates in my opinion, is that
- the motor has a wide window of operation
- the rotation speed is proportional to the strength of the magnet.

Mylobro said he was astonished to see something that defied everything he had learned in school about magnetism.

They were planning on shooting a video and uploading it.

I encouraged Mylow to get some sleep.

Hi everyone,

I have collected the dimensions (in inches) of the magnets from the videos, (as best I could) and was able to source some magnets with nearly identical physical dimensions. I included some edited images based on stills from MYLOW's video http://www.youtube.com/watch?v=shoALtj4j9U&feature=channel


Rotor "Channel" Magnet
Height  .8125"
Depth  .4375
Channel Height  .5"
Channel Depth  .25"
Width .375"

Stator "Horseshoe" Magnet
Height 1.125"
Depth .625"
Width .8125"
Channel Height  .5625"

The closest magnet equivalent matches (of physical dimensions)  I could find were:

Rotor "Channel" Magnet Part #  ACH79 from   http://www.allmagnetics.com/alnicochannel.htm
Stator "Horseshoe" Magnet Part # HS811N  from  http://www.allmagnetics.com/alnicohoursehouse.htm

I have a couple of videos I uploaded just checking what a few neo's would do in the HJ-Mylow arrangment.

For a quick summary, It would not move nicely.  Very sticky throughout the middle and strong at each end of the neo's attached to the wheel.

Hi all,


I looked once again the drawings of the HJ patent US4151431 (http://www.google.com/patents?id=4sIsAAAAEBAJ&dq=4151431) and noticed that figure "FIG. 9" shows a configuration with stator INSIDE the rotor. Figures "FIG. 5", "FIG. 6" and "FIG 7" shows linear "rotor" - not curved to any direction.

I guess that the configuration of placing stator magnet(s) INSIDE the rotor magnets is a key issue in here. For example this picture: http://www.peswiki.com/index.php/Image:Ani-rotar-sm.gif shows a conventional motor design with rotor inside the stator. I guess thís "conventional design" is not a construction that Howard Johnson intended his motor to have?

Any opinions on that?

I hope it's not his brother, because all of those over-the-top comments make the whole thing sound like a practical joke.

I hope too.
But I think there are some malicious people on the internet, twisted enough to usurp an identity in order to put a spoke in our wheel.
Anyway, I would hardly consider his brother to be an "independant person" (no offense to him). What we need is a regular and hands-on member from this forum.
