@d3adp00l,

Do you mean to tell us that you have a magnetic motor whose rotor is making full turns although very slowly? Can you make a video and show it to us?

Not slowly, and it doesn't have a rotor, heck there isn't a stator either. I know it sounds goofy. But its not designed like an electrical motor. The problem right now is I need to gear everything together to control timing so things don't go bang into eachother. And even after gears I may need varible timing which can be done with oval gears with tentioners, to get the rotations correct and controled, but it  looks half promising. And on the same token I have built many of these little boggers only to have them stop short. I don't want anyone to think that I have a fully working motor or anything. The best on rotor/stator designs I have been able to get is about 345 degrees of posistive rotation, the last 15 degrees of negative contribution was too much to get past after 4 or 5 rotations the 15 would succeed, similar to the smot reset point problem.

@d3adp00l,

So, you haven't succeed with it yet?

Succeed or not, I think you have some good innovative thinking. No goofy for me...
Can I have a question? Timing is the essence of your design? Is that the main thing?

By the way, 4 or 5 full revolution is a good result.

Well, as it stands right now the design I am trying to finish had a crude mockup, that with no gears would rotate quite well until the mags would collide. On a previous test bed frame that wasn't designed for the arrangment, I got the mag placement as close as I could with the tight gearing, but as I knew, it bumped after 90 degrees. the previous design was going 4 to five turns then stopping. I was thinking about stacking the desgn multiples high on the same axle, and that was when I took a step back and really rethought how it all works. I went back and read everthing on magnetism, faraday etc. I don't believe that a stator/rotor design will be able to make a full positive rotation. Even the last design I had needed to be released aprox 90 degrees before the bump to get the 4/5 turns. On hind sight that maybe an error on my part, stacking just may have worked, especially after looking at perendev's motor. I don't know if that one works or not, I hear it needs electrical input, which sounds suspicious to me.

Is timing important? As I like to say about most things ya/no. It would be more like the timing on a car. If you're more than 30 degrees out in timing it won't work, I know that much from some basic vector math. if one part is timed in an advanced posistion, it will cause a retarded posistion in another section, which will be counter productive. Which is why I am of pretty strong belief that variable timing might be needed to get it to be really effective. If your car if timed at top dead center, it will run but not really well, it will get you down the road though. If it is timed at 10 degrees before top dead center it runs pretty good, put vaccuum or mechanical advance on it and it runs great all through the power band. And thats what the simple math looks like. It should work with static gears, it should work well with variable(possibly centifical advance) gears.

The reasons for not going to in depth are pretty clear, and not the first one most think of. The internet isn't a safe place, I have already had my fair share of complete system failures with no explaination, and I have seen alot of reasons for disappearing harddrive data, most will let you enter the drive with another machine with the right software.

Its a hope, with some fair backing. I don't have the time to figure all of the calculus and other BS the predict mathmatically. And sometimes things work on paper that don't in the world and sometimes things work in the world that don't on paper, most of the ideas on the site don't really on paper.

And so for the reason that I wouldn't want to never know what will or won't work I really don't want to send it over the net. if it works I will most definitely find a way to get it on video in such a manor that no can say that it might not. Like build it out of plexiglass and walf all the way around it, top and bottom, and shoot the footage in a place that has no power anywhere around.

If there was a way to show everyone what I have so far I would.

One thing, does anyone else have their IE spontaniously close on them when on this site? Or is it just me.

d3adp00l,

Thanks for your answer. Yes & no, good. Everything depends on the viewpoint someone watches from.

I have also been working on a different than usual design and I'll finish the design in summer. Contains a lot of gearing too, to control how the parts can move and when they can arrive at some points...

You may have an interesting setup, wish you the bests!

I think that's just with your IE, strange thing can be some spyware, or other problem... Try with another browser.
