Last night I stubled upon flux measurments that can be done quite easy by a using hall sensor.

Would it be an idea to put two hall sensors on the stator magnet, one at each end.
Voltage of these sensors could be measured by a sound card input (two channels) of a PC.
In this way one could easily get more insight in the field alteration of such setup.

p.s. I will do a bit more research later on to show how this can be done easiest.
( have to visit family today).

Instead of using platters, how about this instead?

Queue,
I don't think adding more spindles, platters or maybe even more rotors will help solve this "closing the loop" problem.  I'm pretty sure all that may make it even worse. This is because I believe that the reason builders haven't been able to close the wheel is primarily because of what's referred to as "moment of inertia".

More here...
http://en.wikipedia.org/wiki/Moment_of_inertia#Overview
http://www.howeverythingworks.org/page1.php?QNum=55

"Moment of inertia embodies both mass and its distribution about the axis of rotation. The more of the mass that is located far from the axis of rotation, the larger the moment of inertia. For example, a ball of dough is much easier to spin than a disk-shaped pizza, because the latter has its mass far from the axis of rotation."

This is why your wheel is not picking up as much speed now, with so much additional weight to move (far from the axis).  It's no longer light enough to gain enough speed to easily glide all that mass half a platter to the next rotor set.

I believe the best way to overcome this is to add more stator magnets.  Could be that you don’t even need to add more rotors (mass) to the outside of the wheel, which would make it even heavier (far from the axis).

Think of a merry-go-round full of kids on a playground.  You need more moms to get it spinning faster.  Not more kids on the merry-go-round.

Also, it seems that there is a sweet spot to the distance of the stator magnet to the rotors, to keep it from being "sticky" (etc.).  When you load up the wheel with rotors and increase its mass, add more stators at that same optimal distance, also at different positions within rotor sets throughout the wheel.

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.




And this is exactly what has been done. The Mylow Motor version of Howard's design in no real way even comes close to approximating the original concept. The C shaped magnet though it may work is not the way to go. Think 'flat' guys. But you watch. I bet I will not get onne single reply to this thread.

It seems to me that one could build a wheel if one could figure out how to induce eddy currents
into an aluminum disc and forget about magnet magnet interaction. That is, the moving and stationary
magnets are needed but only to cause the proper eddy currents to cause rotation. One would need to
spin the disc up at first to generate the eddy currents

"The aluminum disc is acted upon by two coils. One coil is connected in such a way that it produces a magnetic flux in proportion to the voltage and the other produces a magnetic flux in proportion to the current. The field of the voltage coil is delayed by 90 degrees using a lag coil. This produces eddy currents in the disc ."

I have seen videos discussing meters as power generators for the electric co...

I think that would be a radical thing too radical to be true!

Chris C if you didn't notice he was using an motor to turn his disk underneath... So TK's video was a good fake most likely like mylows.
What is so bad about wind and solar we are all so fascinated by the snake oil claims when we have free energy readily available here and now.

@infringer. Thank you for your post. I still don't know whether TK is deliberately doing this to  mislead others or if he has been able to replicate much of myLow's stuff but did not have enough understanding to explain the facts and decided to 'confuse' others via the alt.snakeoil approach but at the same time buying time to do more experimenting to see if he can truly explain his findings.

If it is the former, then I truly have not much respect for people who are only doing it to boost their own egos and indeed it's a complete misuse of time and resources. Seemed like this forum has many of such personalities. Just beats me, though. (same comment for MyLow if he is just doing it to boost his ego!)

cheers

@guys

This is the Mylow builders thread. Please keep this thread free of other affairs or I will have to erase these irrelevant posts. That's why we keep the other thread open for other discussions. Just because no one is posting here since a few days, does not mean people are not working on it.

But wattsup, the eddy currents in aluminum might very well be relevant. I should have posted a link...

http://en.wikipedia.org/wiki/Electricity_meter

see they use a magnet to brake the aluminum rotor... why did we not see this in mylows builds?
Aluminum could be the worst material to use for the rotor... unless the eddy currents play a part?
