Reply to Mark:

Rickoff, my understanding is that you do NOT want symmetry in the stator magnets. Mylow and Stirling have stated the non-symmetry is the key to get it to work.

Hi Mark,

Yes, that's what is said. It may the case, although I don't think so because Howard Johnson's track layouts used symmetry and worked fine. In any case, though, I would suggest that replications be made as exacting as possible to either of MYLOW's working models first, before any modifications are attempted. I feel certain it can be made to work better, but a first replication should be as precise as possible to the original specs. That's why I have posted precise measurements, and I hope these are helpful to replicators.

Incidentally, the Howard Johnson prototype which sparked MYLOW's imagination, and which is constructed with some similar aspects, is shown below:


Best regards to you,

I hate to say i called this one, but...... well i called it exactly in the other thread on this topic. Mylow now has his plans for sale. I saw that one coming a mile away. Create a big frenzy and take it all down to make people feel like they need it just to get them to buy something, sales people do that all the time. I know everyones got to make a living, but.......... well its just smelling fishy to me again. I still keep hope that the johnson device works.

Mylow Magnet Motor Plans; Version 1.1

plans for sale

According to Sterling on his site, all the info in the plans are already free on the Peswiki site. It just isn't organized and to the point like the plans for sale.

Hmm, why is Mylow selling his plans when in the same moment he admits (according to this Howard Johnson Replication Tube Claim) that it was a fake and he fooled people ? ( which i personally believe he was forced to do by the government operatives who threatened his life. He has put way too much effort, time and money into this than i can believe someone would do that is a faker. I trust the guy.)
I hope people go on to replicate this motor, it feels like it has a lot of potential.

[Jules Tresor]

It's not Mylow that's selling the plans, but Sterling Allan, and he said he will give one third to Mylow, 1/3 to Howard Johnson family, and 1/3 to Peswiki ... and as said Aaron, it's all free on the Peswiki website, but well compiled in the plans for sale.
Hope this helps,

Its possible that Video 40 and the magnetic wave or pulse he noticed with the magnetic viewer caught someones attention. I think this was also after he put in the new stator magnet which may have made the pulse more prominent. It was shortly after that when he stopped.

Reply to Cody:

Actually, Cody, Mylow isn't selling anything. These are Sterling Allan's plans. I haven't seen these plans, so don't know how good they actually are, but I do know that some of the information at the PES site is incorrect, and so the plans may reflect those errors. Sterling is a business man, and hoping to make some money from his efforts at drawing up the plans, and there's nothing wrong with that. Sterling wants to keep 1/3 of the sale receipts, give 1/3 to Mylow, and the final third to heirs of Howard Johnson. For those who can afford the plans, it's not a bad way to start a replication and can save much of the time involved in researching Mylow's build. Everything that one needs to know, however, is already freely available if folks will take the time to watch all of Mylow's videos and make notes of what they can learn from each one of them. Mylow did take down all of his videos, but they are still available from other sources.

Best regards,

Actual Magnet Spacing on Mylow's Rotor

I grabbed this still shot from Mylow's #10 video, and scaled the dimensions. The spacing is slightly different than the 6mm spacing that Mylow showed with the magnets laid out on a table top, and which I posted earlier. The narrower spacing at the inside is, of course, due to the fact that the magnet arrays must conform to the curvature of the rotor's perimeter. Although the spacing has been mentioned as being 1/4 inch, the location of that measurement was not specified as being on the inside or outside. Now we know for certain.

Rotor Layout for seven 7 magnet, one 6 magnet array

Here is the rotor layout used by Mylow for the last build that he posted. Mylow's rotor actually measures 17.75 inches in diameter, but it has a 1/8 inch wide raised edge at the perimeter. The raised edge reduces the effective diameter (for magnet placement) to 17.5 inches. This diagram can be printed out, placed and taped at the center of the rotor, and the lines can then be extended outwards to the perimeter to mark the angle margins. The 10mm wide rotor magnets should be spaced 6.36 mm (1/4 inch) apart, measured at the perimeter (see my previous post for alignment photo). If spaced correctly and the magnet array crosses a margin line, arrange the array to split the difference at both margin lines.

Hope this is a help to replicators. Be sure to maintain the correct rotor diameter, correct angles, correct magnet size (10mm wide), and correct spacing between magnets, and you will have the same layout as Mylow.
Note that replicators Clanzer and QueueContinuum both used 10mm spacing (as per Clanzer's drawing) between their rotor magnets, and this is probably why their builds did not work. Queue came close to success, but probably would have done better with the correct spacing and angles.

Dimensions and gapping of Howard Johnson magnets

Hi folks,

It looks like MYLOW has built another configuration now with a stronger horseshoe magnet, and 3/4" spacing between the stator magnets. All in all, MYLOW has built working models in several different configurations. Aside from the models that used the alnico channel magnets for the rotor, MYLOW also tried out configurations using bar magnets that appear to work equally as well, or perhaps even better as far as propulsive effect is concerned. See a video of him using the bar magnets here:
YouTube - magnetic spinning device
If you move the slider to 2:26 elapsed time, and start the video, you will see that these common Radio Shack bar magnets give an excellent propulsive effect that spins the rotor nearly a half rotation. The rotor slows down enough that it can not pass through the second set of bar magnets as they approach the stator magnet, but the propulsive force does look to be strong enough to move the second set through if it were placed close to the first set, as in MYLOWS channel magnet builds. Notice that the only anti-rotational repulsive effect is encountered as the first bar magnet of a set approaches the stator magnet. Shielding could be employed to cover the first bar magnet and make rotation smoother. So I think this method is a viable alternative to using the channel magnets. Note that MYLOW's alnico channel magnets have now become very weak, and his alnico stator magnets don't hold up very long either. Therefore, to simply build one of these with alnico magnets is not going to be very rewarding for your efforts, even though it will be instructive and inspirational.

I believe that this motor could in fact be built with neo magnets for both rotor and stator placements. Neo bar magnets are not hard to come by, but until this time it has been very difficult to source a neo magnet suitable for the stator. MYLOW had hoped to find a stator magnet resembling the one shown in Howard Johnson's patent drawings. He did locate one somewhat similar in shape, but was unable to make use of it because it was magnetized through the thickness, which is the normal configuration for all bar and arc magnets. There is a new neo magnet manufacturing technology which has solved this problem, and it is called Neoform Bonding. Here is a photo showing many of the magnet shapes that can be made with this process:

I have sent a request to the maker for further info on this, and will post that when received. Note that the shape of the "C" arc magnet in the foreground is quite similar to the stator mag in the HJ patent drawings, and would most likely work as-is. I did, however, send the manufacturer a drawing showing the preferred dimensions, and this is shown below:

I intentionally omitted the label from the top of the diagram when sending it to the manufacturer, as I figure that anyone hoping to source a useful HJ stator magnet is going to meet with organized suppression. For that reason too, I would ask any readers not to flood the manufacturer with similar requests. I will post further info as it becomes available to me, and then we can determine how best to proceed with an order for these if people are interested. I really think this stator magnet will be the cat's meow, and that it will make building a usefully powerful magnetic motor very possible. There is absolutely no reason this will not work if done properly.

HJ's patent drawings show a set of 6 bar magnets with the stator magnet positioned above them, and I have duplicated this in such a way as to show the actual dimensions and spacings of these relative positions, as shown below:

Notice that the spacing between each of the bar magnets increases 1/16" at each space from left to right. While this would not be symmetrical spacing for one group of magnets, the pattern would be repeated for each additional set, which in fact does make the overall pattern symmetrical.

Hope you find this post enjoyable and informative,

Rick

Just a thought but could the Stator magnet be a U-shaped electro-magnet?

This might be an interesting configuration for the fly-wheel at the end of my SSG/Window motor shaft....

This is a very interesting thread.....

I have set out to try and make a replication wheel that is easy to build and cheap so more people will be able to play with this thing. This is what i came up with. The main component there is a wheel off a mountain bike. Its only attached to the base on one end and has a mdf top that sets on stilts above the rim. I wanted to try to have a nice flat top that was above the steel spokes so there was little interference from the metal, thats why its up so high. It spins suprisingly easly, nice, flat and smooth. And it free spins for a long time. Has a diameter of 20 1/2 inches, plenty of room to experement. I would not recomend it for high rpm applications for obvious reasons, however i think it should be adiquite for the current purposes. And the best part, it cost me $0.00 Now that mylow is using cheap magnets and with a simple base design like this, maybe we can get some mass replications

[tjnlsn255]

Very interesting approach...

With a rear wheel that has a sproket it will be easy to add a drive mechanism to run a generator.....now that would be a very powerful magnetic motor!

I was actually thinking that it might drive a tesla turbine filled with water as a pump....

I wonder what effect it would have to mount it vertical instead of horizontal....just a thought....

Be happy....

[cody]

thanks tj, those are some good ideas! I would think vertically positioned will be ok, but for now i dont think we want gravity interfering with our unbalanced experements

weakening magnets

I think i know why Mylows magnets are becoming weak, eventually stopping his wheel. To understand this you must first understand what a magnet is and how its made, and how it can be remade in a different polarity. To start, a magnet is made from a piece of metal, look at the picture below (step 1). When you drag the horseshoe across the metal you make a magnet with a polarity like shown in step 2. This is important to understand the relationship between the original magnets polarity, and the new magnets polarity, it comes out in this direction every time when set up like this.



Now, look at step 3 below. Look what happens when we flip our new magnet around in the opposite facing polarity and then drag the horseshoe across it. See step 4, the magnet has now reversed its polarity back to that original relationship that i said was important to understand. Go and try it, its a simple experement. Special thanks to Ed Leedskalnin for teaching me this in his book.


Now lets apply this to mylow's setup to understand why his magnets loose their strength after a while. Look at the picture below, you will see the 2 horseshoe mags like in mylow's wheel. See we are dragging our magnet across the other, just like in my second picture above. Look at step 2, see how the magnet wants to orientate to that special relationship that i said was important. It takes a long time and many passes to reorientate these magnets because they are alligned much stronger than my steel bar above, thats why mylows wheel goes so long before it looses its power, it takes many passes to reorientate them.
