I simulated those magnets in Femm. There isn't more force in one direction than the other. I compared the forces withing a given resolution, and they are pretty much the same on each side, so no net force is left to rotate the wheel. Of course this is supported my conventional physics, and simulations in a condescending software that is made only to irritate magnet motor believers. But nevertheless, the result isn't very positive.

   I have to ask how you set up the magnets. I can gather the rotor mags are one pole to the back spine and another to the two forward facing pieces. Then there is the part that he had the other horseshoe redone. I haven't figured out the exact layout of that one. I even asked him that direct and he bypassed the question. There is really not that many ways the mags can be done so will have to try all of them.

@Thaelin

Go by the sketch - "Mylow's Sketch". Just keep in mind he draws fields in the unpolluted way. Meaning, fields without the deformation by iron filings.
IMO Mylow has been at this quite a while.

I haven't found a reason to trust FEMM for a while now. Too often it doesn't line up with reality.

Has some similarity to Corel castle ... wonder if the math's are similar.  I do not have the time right now to do the math based on code144 dot com.

Anybody’s guess which one on page 7 of http://www.arnoldmagnetics.com/products/alnico/pdf/sacatrev.pdf would be the closest to Mylow’s rotor magnets? Any ideas about the stator magnet?

I think the video is very interesting and the effect is really great if it is real. Now I know he just gave some dimensions etc but here are the main problems I have before jumping on any bandwagon.

First, all throughout the video he is talking and talking all the time. During all of 9 or so minutes, there is not at least 10 seconds where he stops talking and this makes it difficult for us to try and listen to the device for any tell tale electrical drive system. There are also some cars and/or trucks driving outside and it just so happened that two of the times he started the wheel, the noise from a truck or whatever is overly heard and this causes some suspicion. Like, could there be a stepper motor on a centrifugal clutch inside the steel base. Also, I heard twice two clicking sounds as if a switch could have been opened then closed.

The base is solid steel? Or, it could be a motor housing as stated above. That's a concern. I think he does not need all that metal mass in the base if it is only to align a wheel support bearing. An open tripod base should be good enough with a bearing on the top supporting the wheel. If he had such a tripod and can sow the open nature of it as a base, it will increase the video credibility tenfold.

If he in fact is showing something that is genuinely real, showing the north south relationships in the device teaches us some new things that could be applied in other ways and that's great.

wattsup. again, why would he do that? What's in it for him to pull such scam on us? His five minutes of fame maybe or a sinister plot to exhaust the hopes of the community and turn the enthusiasts into an incentive-less, burnt out crowd of losers (as seems to be the goal of @alsetalokin's activity). What's your take on that?

Last night in my chat with Mylow, we talked about doing a video specifically for the purpose of documenting the audio component of his motor running.

He said it is very quiet.

I suggested that he place his camera on the stator bar, then on the dresser top where the motor is setting, which would amplify any sounds of the motor in motion.

Hi;

I will summarize what I think I am seeing in his videos;

First the configuration of his magnets are linear magnets arranged in a fan
or duck-foot array at the periphery of the disc and a horseshoe shaped drive
magnet on the supporting beam. Note that he says his periphery magnets are
polarized with one pole face on the backside, meaning that the two pole
pieces have the same magnetization polarity. So the periphery magnets
are *not* horseshoe magnets in the conventional sense.  A partial device
in an of itself should be very easy to replicate and say “yeah or nay” as
to whether any drive force is evident. Naysayers should cease and desist
until we are able to establish whether or not a drive force exists.

Notice that even one of his first videos he uses long liner magnets and he gets
some small amount of drive power . I would be real nice of him to take a standard
small horseshoe magnet and use it in place of his problematic ‘u’ shaped drive
magnet and see if the unit still runs.

Look, In general what he is demonstrating is *not* supposed to work because
“sticky spots” should form in the *whole array* on the disc. One question is
whether the aluminum disk and the aluminum cross bar is affecting the
units operation. Perhaps the low power magnetics and the aluminum disk
are not allowing sticky spots to fully form.

One thing that is going to be required in a general is to use fastener hardware
and frames around the magnets so that one can swap magnets around on the
disc and between units and the ability to substitute standard magnetics to try
to use new standardly available more powerful neodymium/boron magnets
in place of his specialized magnetics.

It should be possible to use a VCR tape capstan head motor as a bearing to support the
aluminum disc. It should also be possible to glue two cube magnets to a smaller
version of a Radioshack “3/4 inch magnet to get a duplicate of the periphery magnets
but in neodymium strength.

I asked him if he is sure that the rotor and stator magnets he is using are alnico magnets.  He said he is 100% sure, because that is what was on the purchase receipt. 


Hi All

I remembered hearing Mylow describe in his video http://www.youtube.com/watch?v=gqavYG6beSo that the U shaped Stator magnet was just a regular Iron magnet, I checked it again and at 5:13 he did say this so I thought I'd bring it up in case it's relevant to replications.

Regards,
Paul

Omni, the catalog does not include pole position for the type magnet required, i phoned them to no avail.

Thanks. I was just gonna do the same thing, phone them since I also noticed there's no pole indication in the catalog.

i'm having a problem comparing these measurements to what i see on the video

They are quite small: just 1" inch tall, 1/4" wide, and 1/4" thick.  The protrusions at the top and bottom of the C (or top left and right of the U) are 1/8" in length.  They have a shine to them similar to a neodymium magnet.



         either Mylow has the hands of a Barbie Doll or nevermind, I'll figure it out.

I phoned arnoldmagnetics which is located in Rochester NY, the stock cmag is n and s on the c tips, not what MYLOW calls for, they gave me a number for the manufacturer which is located in Chicago ( coincidence?),  call Jim Roocer @ 815 568 2240 , this guy can tell you what they can do
