A better ramp for a SMOT or TOMI track...

[onthecuttingedge2005]

you know, I have been preaching for years to use a small servo motor(timed), use it to only get past the sticky point then let the magnets do the rest.

as far as my recollection nobody has tried it. I know it will work.

I have a bit of a problem with your method in that one would need
to generate and buffer electrical energy...this means an electro
magnetic generator, these work efficiently mainly at high speeds.
I would work to keep electromagnetics out of the back-end storage loop
in case there is some sort of law trading-off coupling of the net magnetic
force on the input side to how much one gets on the output side.

On the other hand, with mechanical storage of forces, one could
visualise a cart slowly speeding up magnetically, restrained by
a mechanical flywheel storage and then a potential follow through
based in a timed torque increasing mechanical gear changing
down shift. The cart would slowly roll through the sticky spot
but at high torque.

I would like to make a large Styrofoam wheel, 4ft diameter or better and place the magnets around the edge, place a little spring load switch on the support and place a trip flange on the side of the wheel where the sticky spot is that way when the sticky spot comes round it will trip the toggle switch in momentary on position to switch on a mini servo that will just turn long enough to get it past the sticky point, add some little mini coils around the sides so the coils will recharge the power pack for the mini servo.

I don't have any really large diameter Styrofoam available in my area at this time, but it would be neat to make a very large but light weight wheel like that.

the added momentum of the servo will add to the magnetic acceleration potential so I don't think there would be a lot of stress on the servo once momentum is built up a bit.

then, fine tune it until it's efficiency increases to its optimal point of recharge and escape velocity from the sticky point.

Jerry:

If you can visit a "home-improvement" store such as Lowe's or Home-Depot you can purchase 4ft x 8ft sheets of styrofoam insulation for the construction of a wheel (link: http://www.homedepot.com/Building-Materials-Insulation-Sheathings/h_d1/N-5yc1vZ1xjqZbaxx/R-100549260/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053).

Also as an idea if you would use a photo/optical eye rather than a "toggle switch" you would have less drag on the rotation of the wheel.

Just my 2 bits.

I'd like to encourage you to do so. Whenever guys produce a wheel like
this they seem to forget one thing; To actually measure the power used
to get the rotor passed the sticky point vs how much could be produced
by a small magnet motor used as a generator. So neither I nor anyone else
can't know if *this* is overunity, or, if not, then how close it is. I'd be glad
to show someone how it is done, if they have an actual experimental
wheel.

Here is videos that shows how easy it might be, obviously I'm
not vouching for the guy's set-up, but it maybe shows some good
ideas.;
