Mechanical Lever to get pass sticky point

[rushi95]

What is the issue with a mechanical lever to move stator magnets and get pass the sticky point?

something similar to (https://www.youtube.com/watch?v=bssBAb6EzM4&t=48s) V gate motor.

All my understanding supports in favour of V gate motor design. But, I am not sure why there are failed attempts to replicate. Can you help me in knowing what might be the possible issues with this idea. OR in general will a mechanical lever help in avoiding sticky point?

What I do hear it takes more mechanical energy than what can be produced in one revolution. I have no means to verify that. What are your thoughts on this?

A lever is doing movement as any other movements. When you avoid the sticky spot, you need some input force. And with that force you need desplacement to actually move the object away from the sticky spot.
Now, the sticky spot is the reason why magnets attract eachother. This force is what we want in a magnet motor, but when the driving forces increase, the closer the magnets are. At some point, the force is not longer perpendicular but purely radial. A radial force just wants to pull the rotor off the hub and not contribute to rotational motion. This is where the sticky spot is.


By using a mechanism to avoid the sticky spot, at the same time you remove the force which drives the rotation, because that mechanism is driven by the same closed system.


You need a separate mechanism that is not connected to the rotor, but that means you have to apply energy to that mechanism.


The V-gate is nothing different from lettig two magnets approach eachother. The magnetic field at the end of the track is where the field is strongest, working perpendicular to the wanted direction. Pass that point you still have a strong local magnetic field that wants to pull the moving object in reverse. Theerfor V-gates can't work.


Apologies for typing errors. My cellphone have very small "keys" and my figer is large :-)

V-gates can totally work. Just have a track between the 2 strips of magnets and a hole in the end to the track. Before a ball gets to the end of the track it drops through the hole. Under the hole is another V-gate.

You tell me how this cannot work? I think lack of imagination and intuition is the only thing that does not work.

You are right about the hole. The ball will be able to drop, but, that is becaus the initial position of the ball is inside attraction area. Do you know what happen if to put the ball too far away from the V-track input? It will be repelled. Yes, repelled - believe it or not. So when you place a ball at the very entrance of a V-track, you have already applied the energy required to enter the V-track. That is why the ball can continue along the track, and finally drop through that hole.


Second, the track must have an incline, then you have a SMOT. But the next V-track will repel the ball slightly before it finish the first track, AND the end of the first track will hold back the drop a little bit due to the strong magnetic field, so the ball cannot fall with 9.81m/s^2. The total magnetic gain is perfectly zero in a closed loop. Friction and eddy currents is two of the factors that prevents the ball to complete a cycle and accelerate.


Imagination and intuition does not help. Physics do things we do not want it to do, and therefor, you cannot force a device like this to work continously, or absolutely not accelerate, just by using imagination and intuition.


Quite frakly, nature does not care about our imaginations. It does what it is created to do. Conserve energy ;-)

If magnets are correctly arranged, it should be possible to jump the sticky spot.  See this video:

Can somebody 'refine' it?
