Howard Johnson Replication Tube Claim

Queue,
In addition to the first two relative sizing and spacing photos that I posted earlier,...

Mylow's "Running Motor" stator is roughly about the same height as his rotors.
See my two new photos below, taken from Mylow's measurement video...

The original photo shows Mylow’s two rotor gaps, relative to the total stator size.  Important stuff I'm sure.  I also think the size of the stator's own gap, relative to the size of the rotors, is probably important too.  Likely not just a coincidence in making sure this doesn't stick, etc.

Looking at the original photo, I noticed that the two rotors, when placed together, appear to fit inside one side of the gap, and to the outside of the other end of the stator.  I edited the original photo to show this relative measurement technique in a second photo.

This ALSO happens to illustrate at the same time that two gaps equal the size of one end of the stator magnet.

Since Mylow's exact magnets can't be purchased anymore, I think these relative measurement techniques could be a quick way for folks to do an easy visual check, to be sure their own magnet combinations are closely proportional to Mylow's magnet set.

I spoke with Mylow this evening as he was driving home then arriving, to see the motor still turning.  He has had it running since 1:00 am Central last night.

As he walked back in his house, it was still running.  "It's still running real fast." We timed it at about 140 rpm (33 revolutions/15 seconds).  He stopped it to try something at around 7:10 pm Central, so it had been running around 18 hours continuous, with no apparent slow-down.

He said it took him 8-10 hours last evening and into the night to figure out how to get the "red" magnet that I sent him will work stably.

He ended up with a configuration of sets of 7, followed by a space of 2 1/4 inches before the next set.  Then the last set has 6 magnets, and the final gap before the first set starts again is 4.5 inches.

"It took me all night to figure out how that red magnet works.  It's all trial and error.  There's a pattern here.  Pattern changes when you change a variable."

"Now it's working beautifully."

He had the stator magnet about 1.5 inches away from the rotor magnets.

While we were on the phone, he move it a little closer, and said it started spinning faster -- too fast for him to count.

He's been talking to his attorney to get advice about the right way to proceed with this thing.  Apparently, the attorney will be coming over this evening.  He's waiting for that before he posts his next video.

I talked him into at least moving the motor over into the kitchen on the glass table so that it's ready to film.

While we were talking, he had a little crash in which four of the rotor magnets came off.

He asked me to stop sending him any more magnets.  He likes how this one works, and he doesn't want to have to keep re-arranging the rotor magnets with each new stator magnet.

He said when you change magnet strength, it changes gapping, spacing between rotor magnets and between rotor and stator magnets.

"It's not easy changing orientation of some 50 magnets."

Different shape/type of magnet, have to change it.  "If you change something, you have to change everything else."

Now here's something fascinating.  He said that the stator magnet gets cold.  His brother had noted that to him.

While Mylow and I were on the phone this evening, he took out a thermometer.  He said the room temperature was 68 degrees.  Then he put it on the magnet and started reading the temperature as it dropped down to about 55 degrees F.  This was at around 7:14 pm, some four minutes after he stopped the motor.

He said the rotor magnets were at room temperature.

"It did that with iron magnet too."

In his present set-up, the bottom of the stator magnet is level with the bottom end of the protrusion of the top of the rotor channel magnets.

When he started the motor up again at 7:18pm it took about 15 seconds to reach its equilibrium speed.

He's always talking about the "sweet spot" where the motor starts.  That refers to where if he lets go of the rotor it begins turning and accelerates up to its equilibrium speed.

I asked him what happened if he just gave the rotor a little spin.  I got the impression that he'd never tried that before.  He is so set on the idea that he wants this thing to self start, that the idea of giving it an initial boost did not occur to him?  I may be wrong.

Anyway, he said, "When I do that [give it a kick start] it starts spinning."

Dispatches from the front, eh! Well done. One might even say sterling work.  . Keep 'em coming.

Hi Sterling

Which new stator magnet(red) are you referring to ? ..
i am using almost the same size disk as Mylow ( 18 inch) and my rotor mags are a bit bigger than his - 10 millimeter width
but this stator you are referring to. I thought he was still using that same odd horseshoe one and had re-energized it with samarian colbalt.

This post was very helpful .. measures and such . .thanks
i am not having any luck with my replication yet.. but still trying to get it to spin up .. 
Probably change config again..
Mylow is right it's hard work modifying the config of so many mags with crazy glue..
i understand his reluctance to change it .. lol !

Can't sleep .. got back up again !

Queue,
Instead of using permanent Super-Glue, and having to scrape it off (etc.) between attempts, consider building yourself a set of little wooden "C" clamps.  This would make it VERY easy to dynamically adjust spacing, try other magnet combinations, variations, etc.

Super-Glue two halves of a popsicle stick to a little block of wood, and add a strong rubber band:

- The block would be the same height as the magnets, plus the thickness of the aluminum plate.

- The popsicle sticks would protrude from both sides of the block, and extend over the top of the magnet and under the aluminum plate.

- The rubber band would wrap around the two popsicle sticks, very close to the magnet, and provide enough tention to hold the magnet in place.

Once you find the ideal set sequence and spacing, you could permenently glue them down for videos.
