New Stagger Stator PMM Design. Review wanted before construction.

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.

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.

How about if you had two or maybe three times the force "of the end" of the track to "bypass" the same amount repelling at the start? In my three rotor four stator design I think you would have more force trying to rotate the wheel then any resistances trying to stop it at a sticky point? I'm not sure how to measure the exact amount.

Tim, yes just like a skateboard ramp.
@vidar I agree about the amount of energy entering > than energy leaving. Which is why I think a multi rotor/stator system would be needed, to do what tim said, have on rotor in accel midpoint, one in accel exit point, and one in entry. I think we can tune the shape of the first entry mag to direct the curves of force lines away from the rotor, and allow the rotor arm to move side to side, to "bounce" off that push.

Tim see if you can get one of the guys who is good with femm to input the quad stator design in and give it a run.

Also one possiblity is the halbach array for stator magnet setup. Countering/redirecting/reshaping the entry repulsion with another field. The only way shield a field is with another field. And also don't forget about bisuth. In the end it may be needed to call upon all of these things, to create a pecular arrangement that allows rotation.

I was just surfing you tube and ran across this guy. Look close to what we are doing but with the rails on the wheel. I think he is over looking the same principle we are found. I can't tell conclusively but he might be pushing the disk into the stator at the start and not knowing it with gives it that shove and it takes off. I have messaged him about it and asked him to post a video showing that it isn't repelling the disk at the beginning.

great video! he seam to not have any sticky spot!

But there is a curious slight accel as it gets to the end of the mags. Its hard to tell if he has a stick or not since he loads the disk into posistion. We will have to wait and see if he reposts.
