Hi

just a quick question, what size is your main wheel ? I ask because it seems to be 2 small!! for the timing you are trying to reach. I have tried 5 1/4---5 1/2 at 2 inch space but get the same effect as you....

The rotor is 144mm per Al Setalokins original measurements. The magnetic diameter is 5" or 2.5" radius. The Octagon flats are tangent to that radius minus 1/8" such that 1/4" magnets are centered on the radius. I'm not sure what 'timing' you are referring to; can you elaborate?

If you want to go in to more detail, then drop me a line

Hi admin, i am just thinking that an amount of "swipe" point in point out, must be there for the affect shown on Als video to be possible, the noise from the bearings would seem to say that? So i have been trying to get the stator(1) to pass from 1 mag to the next at differing times, this causes a slight whiplash in reverse, however it as not been possible at 144mm but at 152mm. I am just in the middle of trying out a disc at 223mm and to my surprise it stoped dead while running down????

Harvey, move the bar as you move to each rotor magnet or have you already done that.

eta: actually mulling it over, it might be enough to use a shatterproof ruler and drill it through the center.

4) A suggestion for positioning and the initial impulse: symmetrically glue some pieces of rigid plastic oriented along the radius of the wheel and sticking out past the circumference. If they're plastic they'll have no effect on field shape. If they're flat and wide (viewed from above) it might reduct the "whippiness" of the input. The more they stick past the circumference, the finer the control.

Sorry about the long response!

b) When the wheel is pushed carefully "over the hill" it seems to me that the "C" will deform as it's pressed agains the field and that energy will be released as it pops out of the other side. Is there again room that the orientation of the "C" could effect how much of the impulse is returned mechanically and how much is wasted as heat when it deforms?

...cont'd

2) Thanks for taking me through the mechanical accuracy of the setup - abit hard to see all the details at first blush.

3) The metal C-shape used to position the wheel for the initial impulse seems like it could have a number of effects:

a) Am I right in saying there'll be an induced magnetic field in the C-shape? If so I think this field will be an odd shape and it's effect on any asymmetry will be dependent on whether or not the "C" faces the direction of travel

Hi AdmonOnDuty,

Thanks for indulging me - easy to pipe up when someone else is doing the legwork :-)

It still looks interesting - and I need to look back through the history here to be better informed - but as you were soliciting suggestions concerning how to drive it etc.

1) I can't see any evidence you're inadvertently biasing the push in one direction, althought it's always difficult to judge - I'm something of a bull in a china shop myself

...contd.
