This is a magnetic engine type I had worked on in the past, in this link being provided. It requires spinning it up into motion first, before engaging the stators:
The link above has nothing to do with anything below.. but it contains enough information to replicate it, so I'm putting it here in the "magnetic engine" section of this website.
As you can see in the picture, it's the simple concept of linear acceleration just made to go in a circle. Space-age technology!
The spin of the cylinder magnet shot along the linear rails adds to its inertia so that it clears the other end! The picture is not drawn to scale, but is a rough concept. I've seen similar engines that work on youtube, but they spin slower. It would work better if the outer staters were the curved rods, and the inner rotor made of the cylinders that roll along some non-ferrous material like a Mylar barrel or something for a lighter rotor. I've seen it done this way in particular, well a similar concept but using a monopole arrangement, only working with one pole instead of both poles working with a spin.
Magnetic engines can be unpredictable the less experience one has with them. They either accelerate to a high speed, spin at slow speed, or stay spinning at the speed you spin the rotor up to before slamming the staters closed around the rotor.
I've seen a similar V-shaped pattern, each "V" overlapping the other significantly, with a magnet rolling or sliding on top of them. It moved at a linear speed though, and slowly. But it had a lot of torque. This could spin a generator head, built to spin at a set frequency and voltage. It might be a little lower amperage, but all it takes is a little spark to create a huge amount of energy using Tesla resonating coils and transformers. An oldie but goodie.
Ironically enough it resembles an Egyptian djed. Go figure! What synchronicity!
I'll have to draft it out real well ... or at least better than the roughie that it is...
If anyone is familiar with the videos on youtube, feel free to post the link to them in the comments.
There are so MANY of them it's hard to find this particular one. A few of them out there actually work. Many of them don't have much torque. Most are impossible to duplicate. It's kind of weird that our technology level doesn't match the knowledge level of Humanity.
