Visimag animation created by Steorn forum member named "/". He says he will keep
trying to see if he can do better. I will replace this image when he has something better.
In the meantime, it's the best we have. Enjoy!

Rotor magnet pivoting animation
Very slow animation illustrating a pivoting feature that allows the rotor magnet to
more easily overcome the resistance when entering into repulsion.


OC13RotatingMagnetDetail.GIF
One possible latching mechanism
In order to present the proper orientation when in repulsion, the stator magnets must
be latched. Here is one possible way to accomplish that.

Here are some dimensions of the 13x8 jig as shown on that other site.

Magnets:
Stator Magnets: 13 ea. K&J p/n 834DIA N42 grade, ring, 0.5 in dia, 0.25 in thick, ~3/16 central hole, diametrically polarized.
# Surface Field: 5340 Gauss
# Brmax: 13,200 Gauss
# BHmax: 42 MGOe

Rotor magnets: 8 ea. generic N35 grade, bar, 0.25 in dia, 0.5 in length, axially polarized.
#BHmax: ~35 MGOe

Stator magnet spacing: on a circle, radius 3.375 in, spaced 1.6 in apart around the circle (or every 27.7 degrees)

Stator magnets each mounted on (above) single ball bearing, 1/2 x 3/16 x 1/8

Rotor magnets equally spaced in rotor, with centerline (axis) of magnets 2.5 in from center.

Rotor on two ball bearings at center axle.

13x8_1.JPG
This is an early shot of the basic rotor/stator blanks. Note the 1/4-20 brass screw used as rotor axle.
This has been changed for a much better arrangement.


13x8_2.JPG
The 13x8 fully assembled.


13x8_d1.JPG
This is what a graph of what one type of data that showed OU performance would look like.
The solid line represents actual data from the test bed, the dotted line is WILD UNWARRANTED EXTRAPOLATION.


13x8_d2.JPG
The famous Dremel with the buffing pad, the 13x8 test bed, and the laser tachometer from Princess Auto.


3Ax8_1.JPG
Showing parts placement, before discovery and installation of the magnokinetic Judson damers.


3Ax8_2.JPG
Showing unit in full motion blur. I can't recall if I spun it up with the Dremel for this picture. Probably not.
Note all three stators spinning. Take my word for it, the "middle" one is going antigearwise--hence clockwise.
In all these shots the rotor is always going clockwise.


3Ax8_3.JPG
The tach reading from the middle stator in the previous picture.


3Ax8_4.JPG
Spinning with the "idler" stators stopped. Note their orientation. They "see" each other across the spinning rotor.
They do not "see" each other if the rotor is absent or stopped.


3Ax8_5.JPG
Taking the measurement.


3Ax8_6.JPG
The tach reading from 3Ax8_5.


3Ax8_7.JPG
Friction testing pulleys installed.


3Ax8_s1.JPG
An early Rogowski coil reading from the rotor edge, far from any stators, ~1250 rpm.
Sorry, I can't remember the scope settings.


3Ax8_s2.jpg
Another reading with the same coil, of the stator magnet, opposite side from rotor.
Stator rpm about 5000.


7Ax8_1.JPG
Another arrangement I tried.
