Working Magnetic Motor on you tube??

...so 258 grams seems somewhat confirmed.

Oh!  And someone later points out (can't remember who - sorry) that the rotor weight can't be right for this calculation because it isn't considering the weight of the magnets.

<Edit Much Later>

I found this just now from Al on Jan. 6th on the Whipmag development discussion:

Mass of rotor assembly, including magnets and shaft adapter, but not including shaft or bearings:
258 grams.

Mass of stator magnet assembly, including holder, magnet, and bearing:
10 grams. Variation between the 13 units is below the resolution of my (home) scale.

...so, the comment about the 258 grams not including the magnets was incorrect.

I believe the wieght of the stator was 10 grams, the magnet is 5 , so combined wieght of bearing and holder would be just over 5. I say just over because the inner portion of the bearing does not move

That would be Behind Enemy Lines ...

maybe someone could post a picture of a ruler on the DVD? might give us a little more perspective here and there...

CLaNZeR nice engineering work!! If the distance to the rotor playes the role here (see attached)? It is bigger that on ALs device??

It appears to be slightly different camera angles. Al's is off to the side while CLaNZeR is straight down.
This would make it appear that Al's stator is closer to the rotor than it really is.
