So you never heard of "Project Echelon".

@ maw2432,

Nice wheel. Are your dice loaded? 

Hi wattsup,

I like the small metal strip idea as it would probably weaken the field or bend it so the entry is smoother but it will also weaken the exit push so longer grouping of "C" pusher magnet might be needed. Try different positioning in the inside of the C and even in the bottom  perpendicular to the platter. Round or flat may give slightly different results.

I'll try to set up a jig to take more pictures of manipulated magnetic fields, got a few of my grand kids home for Easter Weekend so that may slow things down a bit.

Take care,

Michel

P.S.: Got the magnets last night,  the motor generator that is in the making will have a 6.125" diameter and will have 8  6" X 2" X 0.500" that weight a little more than 1 lb each. The electronic module we will try has 2 output one gives positive square waves and the other fills in with high frequency pulses during the same time as the first pulse. If I can couple the hall effect board, that should give lots of BEMF. It comes from a medical air breather assist unit. The fan was noisy so they installed a newer motor with controller board but the electrical circuit was still in perfect condition in both. The controler monitors speed and regulates it according to the set input setting.
 
Edit: Try on the side of the exit/entry rotor magnets also.

I ripped a magnet out of an old hard drive for a stator. It's curved and has a north south.at the ends. My best pattern so far seems to be.

a 3 - 2 then a 3 - 2 - 1 and then it repeats

S stands for a space and R for rotor.

R S R S R S S R S R S S R S S S R S R S R S S R S R S S S  pattern repeats


I mentions it cause there is a lot of odd numbers. Mylow had a lot of 3 rotors sets and 7 rotor sets on his wheels and closed off with an even number don't know if it means much. one last thing the hard drive magnet is a bit strange. by holding it and just changing the angle slightly there were a couple of times the wheel wanted to try and rotate in the other direction.(not flipping north south but by just changing the angle) Stator position and angles seemed to be important for me in the way it exited and enter the gate. Some form of adjustable stand for your stator might be worth the effort.

Someone else might need to confirm this my wheel is slightly warped. What seem to work best in working out my pattern was starting the wheel in the middle or a set or 2 before the middle in what ever rotors I had around the edge. It like the ends balance each other  and I could see a bit more clearly the effect of the pattern I chose. When I started it at the ends it looked like the pattern was a dud as I was building it till it started to get more than halfway around the disc. building a pattern from starting it at the ends all the time seemed to cause the wheel to slow down with the more magnets I added. When I worked from the middle( or a set or 2 before the middle) in finding my patterns adding more magnets did not seem to cause the slow down.

 


 

Change for a better wheel (less wobble) and things are not the same scrath what I said about the patterns 

Hi Queue,

Congrats, you have just found the proper spacing of the rotor magnets for your stator magnet width. Put a narrower stator magnet and 16.4 will react like the one you have on the less effective grouping. 

You might still get rapid demagnetization if it is working in repulsive mode though.

Take care,

Michel

@ BEP,

Why can't folks understand what this means?

My comment is very relevant to his experiment as others try the same thing with a different size of stator magnet, they will fail and start yelling "FAKE" like I've seen in another thread. Then the research will be lost in irrelevant discussions about not using a glass table or independent testing and so on. But I have not seen the slingshot effect that Howard Johnson used in his magnetic motor and linear track.

It is a first step success and I congratulated him for his efforts.

Take care,

Michel

Hi BEP,

I don't see much of a problem in closing the loop if the magnets are not too strong. I would say it is premature to look at this problem as I wanted to wait for further experimentation. Maybe 2 or four pieces of iron wires sticking up from the outside perimeter one at the end of a group and the other at the beginning of the next group would nullify that dreaded close loop problem.
 
It may be tougher than that but not impossible to achieve.

Take care,

Michel

Edit: Copper shielding or something esle could be use. Are you familiar with Clanzer experiment with 2 adjacent magnets on wheels and he tested many different metals to see the effects? The answer could come from that too.

@ BEP and christC,

I have read somewhere that Mylow tried with a second stator arm and that did not work.

I think an even number would be tougher to get positive results from but an odd number would probably work as long as identical stator magnets are used.

Take care,

Michel

when you add more magnets the flux seems to interact and slow the hole wheel down. I was wondering about some form of magnetic shielding to try and separate the effect of the rotors at the stator.

This vid shows a poor mans magnetic shield at the end of it using what looks like a bit of a metal measuring tape. The metal tape would not be shielding the field I guess it would be directing it away some how.

If we could use something like this to drop the entry barrier or the effect of the whole circle - You get what I am thinking.
