MylowHJ Replication - Discussion
« on: April 05, 2009, 02:49:58 AM »
@builders

OK here we are. This thread is for Mylow Replication - Discussion. We welcome builders and serious collaborators. Any talk of any defamatory nature will be removed from the thread because we want this thread to be solely for the technical aspects of member builders.

I would also ask that all builders open their own thread located here;
http://www.overunity.com/index.php?board=117.0
and use the title convention as follows "Mylow Replication - username".

Other members should not post in builders threads unless it is very pertinent because we don't want to end up with builder threads having 100 pages. Keep discussions here. This will be easier for builders to following since they won't have to wade through endless pages for specific build specs.

So gather up your tools and come on down.
I will keep this first post location to eventually provide master links, etc.

Glad to see a new thread....heavy vibrations..make a good novel.  I am a long time mag motor experimenter and i am trying some smot variations and find all your work interesting. I am also praying for a viable PMM.

Anyway pls builders help me with a inexpensive source of the rotor mags.. cheapest I find is about 4 dollars a piece..
also I am ancious to see clanzers workup??  and I wish that Queue's 3rd video showed some stator involvement just to see for ourselves the reaction or lack...pls

thanks for any info
ps I have looked  at most if not all of the published info

@queue and everybody.

I am wondering why in queue video http://www.youtube.com/watch?v=SHCgXWN-15A there is less deceleration entering into the last set of 7 magnets then the first 2 sets of 7. Queue any thoughts - are the measurements exactly the same?

It seems to me that the major problem facing builders is that facing a salesman, closure.

How does the gap know that there is a long string of gates on either side?
The customer has to be confused so he doesn't realise he has got to the point of no return.

In designing gears one chooses prime numbers for the teeth of meshing pairs so that wear is evened out. It is possible that the same kind of technique could be used here. Mylow has already used this to some extent by breaking up the rotor magnets into groups and having a gap. His intuitive idea could be extended by having random sized groups and gaps. Think of it as confusing the closing gap by having a lot of small waves of different wavelengths so that no big wave can slosh around to raise the walls at the end. Probably the only ratio which has to be kept constant is that between the pitch of the stator poles and the pitch of the rotor magnets. The optimum pitch for this could be found by repetition on a given group of rotor magnets, prime number 7, say.

Thank you wattsup. As always; your courage and enthusiasm is inspiring.

@captbuck

I''m copying over a post I made from the other thread:
http://www.overunity.com/index.php?topic=7039.msg166106#msg166106

ACH79 Channel magnet Alnico 5 magnetized with two poles
100pcs $1.28 each plus one time charge for tooling of $175.00 6-8 week delivery

They have 2 other similar magnets in stock for immediate delivery:
0.280 X 0.370 X 0.750 Channel magnet Alnico 5 magnetized with two poles; 100 pcs $1.38 each
0.380 X 0.370 X 0.840 Channel magnet Alnico 5 magnetized with two poles; 100 pcs $1.48 each
They both have 0.125 hole in the middle.

The following image is the fax they sent me.

Take care.

@queue,

I'm still curious about this suck-in-spit-out business within an individual cluster I mentioned couple of times. I don't think it can be tested when the rim is complete in your case because it very well may be that the magnets you're using are too strong and the clusters cooperate and don't act as isolated islands. As I mentioned before, what we need in principle is a hybrid between the magnetic propulsor and the tri-gate. My hope was that Mylow's may be such a hybrid and I'm still not satisfied w/ the outcome until I clearly see that it isn't. I wonder if you intend to do more work with your contraption. If not I'll be very happy if you could send it to me (at my expense) for, say, a week to do some experiments with it. Alternatively, if you think it's appropriate I can come up to you in Montreal. As for my own rig, I don't know when the magnets will arrive and the cutting of the Al disk which I'm planning to do only after that will take even more time. I was thinking, there are available constructions already to carry out this simple test. One of them is yours, which is the closest to me, and I thought maybe it wouldn't be a bad idea to mention this to you.

Hi everyone,

Good move for the thread wattsup.

Here are a few observations that might or not help.

The disk when it starts running becomes a Faraday disk. So it is very much influenced by the surrounding magnetic field of the Earth and all the electromagnetic pollution added.

The other is harder to imagine since it is based on a drawing in "The Electrical Experimenter" but don't recall the month or year of publication. The drawing shows the relation Earth/Moon by enclosing Earth in an offset "U" shape or horseshoe magnet and the Moon spins around it always showing the same face.

The third far fetched idea comes from Boyd Bushman "celt" stone as the mode of propulsion is the counter rotating force.

Take care everyone,

Michel

P.S.: If the MIB were to threaten my family, I TOO WOULD DECLARE MY RESEARCH A FAKE WITHOUT HESITATION. Think about it.

I hope it can help anyone working on this project.

G'day all,

As most of you know I have always been suspicious of the Mylow device. The attempt at replication that did impress me was the Queue replication. There is definite movement there from cluster to cluster.

Having said this, I strongly suspect there will be problems as he attempts to close the circle as it were.

Perhaps there is a way around it. I propose to split the system in two and have them operate in tandem. Below is an illustration of what I mean.

I have drawn the two disks side by side, though in a real motor they would probably sit on the same shaft one above the other.

Something to think about perhaps.

Hi everyone,

@ Hans, it looks a lot more like Tesla's homopolar generator with 2 disks (bifilar homopolar generator) where the disks are coupled by their circumferences with a conductive belt.

One thing that is so big that I did not see (and was told) and I have to share. Howard Johnson's Stonehenge motor does not rotate a disk but it rotates the stator as in Mylow's and Queue's replications. He also uses both ends repulsive force (1 magnet structure at each end of the arm) to achieve this. Maybe something interesting would be seen as rotational speed and stability of rotation.

Take care,

Michel


Edit: Each time we deviate from the original, we add complexity and difficulties.

By definition a stator is fixed and a rotor moves. A stator that moves is not a stator.

Tandem as you put it causes more friction on the rotation of the disc ...


If you really want something to try buy some carbon fiber and polyester resin and hardener off ebay cut out your circle and harden it up...

The lighter you make the disc or magnetic rotor the less friction you will have ...

I dunno what is the gig with keeping everything aluminum other then the fact it is cheaper and light weight ...

Good luck just a suggestion take it for what its worth.

Honsvonlevin got it correct...

Think of rotor as short for rotation and stator short for stationary this is how I always remember the two!

And I almost wonder if the people who named it did not vision the same thing?

There is not necessarily much of an increase in friction if both disks are mounted one above the other on the same shaft. I only drew it that way because the principle is easier to see. In fact there could be multiple disks.

Hi,

Howard Johnson's Stonehenge motor does not rotate a disk but it rotates the stator as in Mylow's and Queue's replications.

It rotates what Mylow's and Queue's replication use for their stator. Sorry if my phraseology was confusing. I am a diesel mechanic with 35 years experience, so I know what is a stator and what is a rotor. English is a second language for me and I am sorry if I did not express myself clearly.

Howard Johnson used wood and aluminum as basic ingredients along neos, ceramics and flexible magnets in the Stonehenge motor. The aluminum disk used by Mylow might be just the ingredient needed to do away with the complex magnet arrangement used by the defunct HJ as it may induce currents that creates a magnetic harmonization of the fields involved in his rotor. Horseshoe magnets are something special that more people should be familiar with.

Take care all,

Michel

I think that is very ingenious.

Congratulations.

Indeed one could extend the idea to multiple disks. Then each of the disks which was away from its gap would only have to contribute a small amount to the gapped disc to get it past its sticking point.

Ideally all the discs would be on the same shaft and well separated so as to prevent magnetic interaction between discs. But so what if we finish up with the proverbial ten foot pole. The first job is to illustrate a point of principle, i.e, that one can get continuous rotary motion out of a lot of magnets. Bells and whistles can come later.

Edit: I'm glad to see you approve of my suggestion of multiple disks and have modified your post accordingly.  ;).
