Working Magnetic Motor on you tube??

@ Ken
Is the SHCS screws that you have magnetic or non magnetic?  Some stainless is, and some is not.

Please verify and let me know.  Thanks!

Cheers,

Bruce

Hey Bruce,

The SHCS screws that I have are magnetic. There does not seem to be much choice out there.

Yes the anticorodal in in facts the 6061 T-6 , abouth the screws I have to go to the proper shop to get some nylon ones , I'll do that as soon as i can 
To be really  precise I should also change the base material from HDPE to Perspex acrylic , according to Al's specs .

About the pics and the mags alignment I went trough my precious savings  ( from various Al's posts ) and I've found the question about mags i previously refferred to :

korkskrew:@alsetalokin

Could you please recheck the polarity markings on your stators? I think they may be marked opposite of how the rotor magnets are marked.


Checked and doublechecked many times, again just now.
The markings are consistent on all magnets.


The reason I asked is this picture
http://www.overunity.org.uk/ocpm/compare1.jpg

. One would expect the stator to rotate so the opposing poles would be attracted to eachother. In the photo the colored ends are pointing the same direction suggesting that the N pole on one magnet is colored and the S pole on the other magnet is colored.

This is the last I'll say of it. I don't want to be a pest. I'm just trying to build an accurate model in my computer.

P.S. Just out of curiosity, did you read my AGW sync theory? If so, any comment?



So Clanzer and I both made the same mistake, is that what you are saying? No, it looks to me like his markings agree with mine--yes, my picture was taken in motion with flash, I don't know the circumstances of Clanzer's pic. I used the magnetic field visualizing film to identify the location of the poles on the stator magnets and marked the border very accurately. I don't know how accurate Clanzer's marks are or how he determined where the poles are.
Again, I have checked and rechecked the polarity markings on my magnets. They are consistent throughout. All like poles are marked with like colors.
I made no attempt to mark the rotor magnet walls exactly, as I did the stators. The rotor magnets are just marked for polarity. And their markings are consistent.

So now I 'm in doubt if also the pic we are thalking about could have been a flash or  a strobo still pic and therefore the missed alinement could maybe be justified ??

@Bruce_TPU

I wonder if you should try moving the dampers around a bit. Sounds like you might be getting something but it is going a bit to fast on entry to sustain (suggestion courtesy of EmeraldSong).

@ ALL

RE Rotor diameter question

I'm from the California, so I don't use the Metric system all that much.  As Omni jokingly pointed out to me, Al's rotor diameter is 144 mm by a "fortuitous coincidence."

... Q:  How common is it to choose 144 mm as a design specification?

I think a normal designer would choose 150 mm -- nice, round, exactly between 100 mm and 200 mm.  

... Q:  Any thoughts on how/why Al chose 144 mm?  


Of course, I have a few "non-scientific" thoughts on the dimension.  Given what we know about Al, my thoughts might have credence, but I'm asking whether there is a good scientific or machining basis for the rotor dimension.


Cheers,  

Yada..

@vipond50,

As I promised you, I just checked the disposition of the stators with respect to the rotor?it?s very similar to what @AndreaGanora has here: http://www.overunity.com/index.php/topic,3871.msg75827.html#msg75827.

I have now the two rigs with me and will do some experiments with both. Later will post at least some soundtracks for @Yadaraf to analyze, if he feels like it.
