New permanent magnet motor on youtube from Roobert33

[Omnibus]

Hi.
My small observation: all guys here seem to neglect the small contraption at the bottom of the original R33 machine: it is never seen in any replica. I think, it gives a momentary "boost" to the wheel.

Yeah, the role of that detail is unclear. Seems like what you get as boost is due to spending of the earlier produced energy. That's how it appears superficially but there may be more to it.

One positive thought about the magnet at the bottom.... Maybe it is a control to slow the motor down since it might speed up too much and break....  if it really works.

Wonder why R33 used fake magnets in the V-track - made of CNC machined steel rods. I also wonder why the seesaw in the very bottom wasen't affected by the "magnets" at all, except when it was activated by the cam - it should stick instantly into the "magnets" in the V-track. I also wonder why some still believe this V-track was a working one which is worth replicating.

Just wondering.

Just a quick idea.

I found this vid on YouTube, please take a look and then read the on...

As you can see (If I'm making sense of the vid), the ball runs up a slight incline and because the ramp is quite far apart, it is able to drop out (via gravity) and continue rolling.

The point is: that the ball drops out at a height which is higher then its starting point.   This would suggest that the track could be bent around in a gentle curve, decreasing in height, until its at the starting point of the ramp where it might start again.

Thoughts?

Let me apply some facts about such devices:

The energy that appears to "pop" up from nowhere, are actually the work done by the hand in advance. What most people doesn't know (Or just don't admit), is when releasing the steel ball further away from the ramp, it will repell and go backwards. Everyone who have tried this SMOT ramp knows this well - me included. This repelling force is easily overcomed by the hand which place the steel ball close enough to be attracted. This force over the required distance to get close enough to the ramp is the energy you need to apply in order for the steel ball to climb that hill in the first place. So what to the eye appears to be OU are not OU at all.

What seams like to be a potential difference when it regards the hight is also misunderstood. Yes the hight in altitude are greater at the end of the ramp, but the magnetic field which is affecting the ball, is virtually leveling out the difference in hight because it is more attracting at the end than in the bottom. Also when the ball falls through the ramp at the end, it does not fall at 9.81ms^2, but less due to the attraction to the magnetic ramp which slows down the acceleration towards the ground.

The above facts are the very reason why such ramps cannot be looped back. A succesful loop back are depending on overunity. No overunity will not make a successful closed loop. Also for these reasons there has never been a single video on Youtube of a successful closed loop.

EDIT: Furthermore; The ramp is also working like a hoist which exchange weight pr hight with time. It require less force but more time to roll a 1 ton car up a gentle uphill, but if the end of the hill are suddenly terminated into a steep hill, none are able to keep that car from falling down. SMOTs are nice tricks, but not OU.

Complete nonsense.
