This is another way to overcome the sticky spot.

@nievesoliveras,

Have you actually tried this?

I have not the means to try it.
But my recomendation is to put each sticky spot at 120 degrees around the rotor.

Doing that, there always be two v gates working against one sticky spot.
If I had the means to do it I would. Why not. It seems promising.

Jesus,  If you use only one bar magnet with N at one end and S at the other end... I would think you would have a problem with V gates being designed with one leg N and the other S.   You may need 3 individual bar magnets for your design to work.   Am I missing something?

@maw2432

You are right! The schematic was drawn incomplete just to show the idea of the 120 degrees of the sticky spot placement.
I thought that it was understood that each section of the rotor has its own bar magnet on the same rail.
The width of the bar should cover just the portion of v gate it is actuating on. But all in the same rail in order for the two against one to work.

Jesus:

I do not know if that will work or not but it sure is a new approach to the sticky spot problem.  By working 2 against 1 it might have a chance.  Again, great thinking on your part.

If you got one V gate, with its sticky spot, - you know the V-gate we all know doesn't work, and take this V-gate and connect together with two more V-gates that doesn't work either. Let us now connect them together with a common shaft, and align them 120 degrees apart. Is it any reason why they now suddenly should work?

I cannot see the logic in this...

You will never avoid the sticky spot. You even it out, but you also add more and more sticky spots as the number of V-gates increase, doesn't you? Each sticky spot must account for itself. 100 V-gates = 100 sticky spots. 100 / 100 = 1, which means each sticky spot must account for its own sticky spot.

Consider: sticky spot is associated with attracted configuration. In fact, there is no sticky spot when magnets repel; this kind of configuration is easier to manage, though attracted one is more powerful.

For the negative thinkers.
I stated very clearly on the schematic that may be yours work better.

Just dont sit there and criticize my efforts. Present your solution to it.

Jesus; I sense the frustration in your post. Please do not confuse "negative thinking" with people who have built numerous motors and see why they do not work. Buy some magnets and glue them to a 8" diameter circular piece of wood. Use some simple bearing so that it will turn. Holding some magnets in your hand you will be able to cause the rotor to spin as you move the magnets (the stator magnets) back and forth. Some of us have gone way beyond this. You will see the problem.
The sticky spot and the lack of torque. Not all problems have solutions I know on this site that is cause for being burned at the stake.
But what is true is true. Keep on playing though it's great fun!
If I was made of neutrinos I would be able to walk through solid objects but since I am not I suspect I will only be able to use a door. Point being not everything is possible even if one thinks it is. I suspect I will be flamed for posting this, but...

I will try not to post my ideas to solve something. It is just an impulse I have when I think that I have the solution.

I beg eberybody's forgiveness, I will try not to sin that way anymore.

Searching the right spot for the pulse to be, this maybe can solve the sticky spot problem.

Jesus

Jesus

I think  you are going in the right direction with  your sticky spot pulser.
Your idea  would make the V motor very similar to a magnet motor that   has been on my to do list for a long time.

I believe it was Stephan  Hartmen that said  any magnet motor that is OU would  have to use iron .
I do not believe in such sweeping  comments.........but i think he is  right in this case.

What I am talking about is using the magnetic fluc from the  outer magnets a little more indirectly

Keep in mind  this is  just a theory..... I do not have the final geometry of the parts down yet.

For full potential  this idea would have  iron bars all around the rotor.with magnets  attached to the outside of them.
These bars would  be touching eachother so the magnetic  flux from the magnets could  flow from one bar to the next.

on the inside of ring of bars is another ring of iron bars.......in between  the 2 rings of iron bars would be thin coils.....coils  with the same  purpose  as  the coils in your idea.
These  coils would have iron cores to conduct  the magnetic  flux through the coils.

I was planning on  using a Bedini type circuit to drive the coils......although  your setup should work too.

The reason for  using the iron  is  for the chance to  switch the magnetic  flux  on and off.

WHen  the  coils  are inactive   the flux from each magnet will flow through the coil  and into the second iron  bar .......the magnets on the rotor  will then be more  attracted to the inner iron  bar.

WHen  the coils  are activated  the coil  will inhibit the  magnetic flux from  flowing to  the iron  bar directly on the other side of the coil  so that flux will transfer laterally to the bars on each side and help to attract the magnets to them.
Another little  plus of this design........because of the  iron .....when the coils are activated  the inner iron bar directly  below the coil will switch polarity ........so instead of a sticky spot........you have a low  power attraction

I think a more advanced  version of this idea would have the magnets near the ends of the bars.........then shift the magnetic polarity from outboard to inboard.


Jesus ........ what every  you do..........do not give up.

There are many people here that do little except  try to shoot down  good ideas .
To have them attack you is  probably a good sign.

Hi Jesus,

Do not give up on your ideas, I'm very grateful that you share them. They may or may not work the way we envision them but they do spark other ideas.

@All,

Just throwing out another idea. Have the cylindrical v-track stationary but have an outer wheel with the magnets attached that moves.

Instead of using mechanical switching to get over the gate have the v-track so it bows inwards almost like a deformed cylinder. You are essentially taking the path from the pull out that you emulate with your hand near the gate and inverting that path into the surface of the cylindrical v-track.

From Laurent's video the path would be a sharp ramp inward then straight out.

Yes, this is true because the magnetic material itself are attracted to the other magnet even if equal polarity are facing. However, if you base your design on a repelling machine, the torque provided by the repell are also weaker - because there are a slight attraction between repelling magnets, see? So you will end up with the same result. Take attraction mode: 2 - 2 = 0, but also repulsion mode: 1 - 1 = 0. As you see the sum of the forces will be zero no matter how you put it.

A sticky spot is a notch on the track, but a repelling spot is a peak on the track. Both are accounting for how much of the opposite forces there are on the rest of the track. The sum will always be zero. Both are the reason for eachother to be just like they are.
