New Stagger Stator PMM Design. Review wanted before construction.

Well, I have been playing around with my ring magnet and the rails and I'm not finding the sweet spot Tom shows in his video. I was hoping it would be easy to find. What I have found is that I think Tom had his poles backwards. Like the graphic below but I could only make it work with the alignment shown in the photo with the poles the other way around. It gave the exact response Toms  did in the video but the problem is that you have to push it into the start. Its really not that hard to push in but it wants to push it back and away from the start.

Here is a video of my rails. The pole alignment is opposite of what Tom said his where. At the beginning you can see the rails are pushing the ring back. Then I move it to the point where Tom's video starts and it acts exactly the way it does in Tom's video. Even with the little twist at the end.

Note: Let me know if you can see the video. I was having a little trouble with it. I'm also trying to post it to google so we'll see what happens. Thanks.

Is that the rotor mag you plan to use? its massive. And the sticky point becomes clear in your video. Its not hard to get things moving in front of the push effect of the magnetic pole. How thats gonna play into effect in a motor design is a bit hard to tell.

The mag is the exact same as Tom used. I ordered it from the same supply company. All hope is not lost but I do think Tom's rail design isn't much better then a vgate if at all. The sticky point is weaker but so is the energy given to the magnet as it leaves. I have a couple ideas I want to play with and see if they work. I don't think I have seen anyone else use the three rotor arm and four stators setup where two or more are pushing when one is at the sticky spot? I am also thinking about not curving the rails so that as the rotor swings around it intersects the rail at the rails midway point. I'm not sure if this would really do any good but I am going to look into it. I also might play with a continuous track all the way around. I'm pretty sure this has been tried but I'm not sure.

One thing I did learn is that it can travel in a straight line through the rails.

I'll try to post pictures of some of these ideas when I can. Its a slight disappointment that Tom's video was misleading. Only a hundred or so dollars spent and probably a few more for poops and giggles!

The problem lays in the 6 first seconds of that video. The "solution" is to manually bypass the repelling force, but the same force in the end of this track will not be enough to push the rolling magnet into the 6 first seconds.
