Of course a rail gun works with DC power it's not the sudden burst of magnetic field that causes the acceleration it's the presence of the magnetic field, when will you get this?

Low-q I think I'm going to stop posting in your thread or else people will call me jealous again  ::). You keep making up these pointless remarks that I'm starting to think you are deliberately selling your disinfo. I asked you to do some research and you didn't do squat. But you act like you know what you're talking about while you clearly don't. Maybe one day you will go "aha now I see what he meant". But that day isn't going to be soon it seems.

You're right, I was confusing this with a coil gun or something.
But anyway, if you bend the rails around to make a rail circle, the projectile will loose its magnetic reference bacause the magnetic forces that is pushing the magnetized projectile away, will in a closed  rail loop be pushed equally from both sides.
The projectile just want to escape from the magnetic field built up in the straight rail- and projectile conductor. And it can because there is no magnetig field in front of the projectile that stops it. In other words, the magnetic field only occour in the closed current loop, but as there is no current flowing through the rails in front of the projectile, no magnetic field is made there. The current loop is limited by where the projectile is present, so to speak. maybe you can almost close the rail loop, and hope that the projectile is jumping over for a new round. If you can do that with permanentmagnets, it might be worth trying it. Looking forward to your results.

Interesting reading, and I try hard to be open minded.
The thesis is however not very related to permanentmagnets, and how you can utilize the properties of a railgun by using permanentmagnets instead. The rail and the projectile is a coil, an equivalent of one permanentmagnet that expands - not more. A long permanentmagnet magnetized through thickness, like a railgun is, if you break it in two, those two parts will be forced apart - almost like the railgun works. In fact a permanent magnet want to pinch in the direction of magnetic lines, and expand angular to the magnetic lines, so to speak. So if you are going to make a railgun-motor with permanentmagnets, i really don't know how you are going to make that working as the projectile in a railgun works like a monopole in the circuit. And as far as I know there is impossible to make a monopole with magnets.

You can allways try to close a magnetic loop in the rotor or stator, so you get all the lines in a circle in order to simulate the magnetic field around a wire with current flow, and put that circular magnetic field between two magnets attracting eachother. In my mind it would work, but after an experiment with that, it didnt work at all.

I once did an experiment like in the picture below.

Anyway, I feel we are going quite off topic now, and I blame myself for it - even if it is interesting discussing motordesign with you :)

Go ahead a build your idea like an aircraft radial piston engine. I like your concept and have my own I am in the middle of building using the radial concept, but not with your "cancelling" idea. Just build it! Good idea.
Thanks,
Jeff

I guess I have to build it. I will figure out a way to build it. :)

Wow, I went through a lot of hassle to say:

broli, don't be so sensitive! It seems like Low-Q is making reasonable counter argument. Now with that out of they way, I have to say, I don't understand one bit of this except your (broli) simplified explanation of the railgun. I was excited to hear that because I have been thinking the same thing for six months after I saw a railgun. After that I became aware of the fervor against this idea but I am not satisfied why it won't work.

I can't tinker with parts to find out if a complete circle can be made because it's expensive (machining needed). I do however, want to model it with software. But it seems like such software would exist. I know about Maxwell, but I wasn't able to figure out how to create such a motor with it.

It seems to be proven that the thing can go around nearly full circle. The problem seems to be the jump past full circle. Even though I'm not convinced it won't work with the stated or similar design, I'm willing to use electronics or gravity to complete the circle.

So we need a fixed, spinning stator and a circular rail (wheel). Does software exist to test this in an animated model, or do we need to write some?

You right on track with your suggestion of making a circular smot.
The only problem you have is that it has already been made.
And yes, it's well overunity according to sources.

Re: This must work! .. Does software exist??

That's cool. I have seen that design before. That's the first time I saw it keep going though. However, it's not like the railgun design. But a greater question I have is, does software exist to model this stuff? I guess 3d software is what I'm talking about.

Suppose we want to find out if we should use big magnets, or needle magnets and how far apart to put them; And then watch the result of the action: Does software exist that allows such mechanical action to be modelled?

I mean, suppose I want to use software to place a magnet and then another magnet next to it. I want to press "start simulation" and watch what happens. So I guess it's simulation software.. I want to find out if such a program exists or if we need to create it.

There is no such public program but I bet the Sprain group
has developed such a tool to help them design these motors.

Btw, here's a guy that seems to have found a way to calculate this.
Read point 3.

SMOTs are not OU. It looks like it because the ball is visually higher at the end of the track, and therfor visually contains greater kinetic energy. But the ball is affected by more than gravity - namely magnetism. The magnetism will during one revolution counterforce the ball as well as forcing it to move. These forces adds up in zero. As both gravity and magnetism is conservative, there is no net change made in kinetic energy within a SMOT.
