I hope someone gets a replicaction done soon,I haven't slept more than a couple hours at a time this past week.

just testing , can you connect and see if its any good? Broadcasting live from tenerife

Works fine in IE6 for me here on the east coast US, but nothing shows up in Firefox for me.

Good for you mate. You've got the right attitude.

Started doing some weighing and wind down tests with NO stator magnets.

(http://www.overunity.org.uk/ocpm/tests/weight1.jpg)

The little 3mm RC bearings top and bottom give a good 4 minute wind down from 1000RPM with Rotor Magnets.

Find Video below:

BTW I span it upto 4000 RPM without magnet just now and it started too lift off the table at 2500 RPM, so Blue Tacked the feet down and they are only just staying there at 4000 RPM, so be warned LOL 

Span it up with Air Line as below.

Off to find a bit of timber too screw then base plate too and add the extra weight !

Hi Oak,

Thank you for the information! That is most helpful.

While looking through the links, I noticed this quote from Al:

Ahh, no. These tests have so far only been performed in my basement. I discovered the effect over the holidays, today was the first day back at the lab, and I had the unit disassembled for the bearing mod, and didn't put it back together till I got home.

(http://www.steorn.com/forum/comments.php?DiscussionID=59687&page=7&Focus=2266671#Item_22)

Does this mean that he had the unit working when the screw was still being used as an axle?

God Bless,
Jason O

That's how I would interpret what he said.

@CLaNZeR,

Thanks for the video. I see your rotor being 199g is lighter than @alsetalonkin's 258g. Could you try turning it first by hand? I wonder if these 1000rpm were imparted by hand or not? Recall, when @alsetalonkin turns it by hand the spin is at ~400rpm. As the things are going here I'll be starting these experiments on Monday, hopefully. Have the magnets already, the bearings will probably arrive today bu the parts won't be ready till Monday.

I didn?t like al?s reply to sean about the materials, on the steorn forum.. was it me or was he being patronising?

@ Sean

The rotor has only reached speeds below 2K.  The faster the stator magnets spin, the slower the rotor.  Where Al ran two of the stator magnets anti-gear wise, where they both sped up over 12,000 rpm's, the rotor was 1000 rpm.  So I don't think that you need worry about lift off, just yet!  LOL

Good work!!

Well he never answered the question did he  I said I had ordered some HDPE as he had recommended on another thread with the answer coming back as :

************
Nylon is about like congealed asphalt as far as machinability goes. It is usually molded to shape.

The Delrin (or Acetal in the civilized world) is what I used for the early rotors and all the stator bearing/magnet holders, and the 3.5 mm to 1/2 in shaft adapter. It is by far the nicest plastic to machine. It has a sensual quality about it that is somewhat indescribable. Why, when I first met Delrin...but that's another story.
Oh, and the mechanical properties are nice too.
***********
So maybe I should or ordered some Actel hehehe

@btentzer,

Hey, what are you doing over here kicking it with the magnet motor guys? 

Get back and finish your TPU before it gets cold!

I can't help myself Mike!  It is the "attraction" to something that might very well be history making.  (every pun intended.)

And get it right, it's, "Kicking it with the TPU guys and rotating it with the magnet guys!" 

 Actually they are both about rotating magnetic fields, just different ways of doing it.  Or is it?  What makes SM's TPU work?  He doesn't know why.  What makes this work?  Hmmm......

A quick video showing the difference between hand and air line.

But we got to plan for the future Bruce hehe, When I pop it in me car it is not gonna go very fast at 1000RPM is it?

hi sean putting more wieght on the rotor makes it easier to sync as the initial braking effect is not as pronounced with 3 times more wieght . i have now put perspex disks above and below to triple the wieght ot plastic rotor and it seems to make sync easier. I am off to turn some stators holders for the magnets i have here and then maybe can do some reverse spins

[Omnibus]

@CLaNZeR,

OK, makes sense. Yours is lighter and you get it to spin by hand at over 500rpm (his is around 400rpm with about 120s wind down time). Would you by any chance have a DC motor to mount the rotor on it and measure the current and voltage necessary to have it spin at 550rpm on the one one hand and at, say, 1500rpm on the other. Let's see what the difference in power is. Then we can compare these data with calculated ones based on the moment of inertia of the rotor.
