New Stagger Stator PMM Design. Review wanted before construction.

I have three shipments of magnets coming in hopfully soon. However mags4less or whatever isn't gonna ship anything for a couple weeks, which puts off the full scale of what I want to do. And I still can't find the gears I want, and the couple I have right now, my machinist can't remeber where he got them from. I love working with people who have no particular care about projects like this. I will have to dismantle part of my frame to take the parts in to have it matched, but maybe in a couple weeks I might have something to show for it all. I also have about 2lbs of bismuth coming in for fun.

Does anyone have anything to say? I would appreciate any feed back positive or negative. Thanks,

Hi Tim,

Its me. I am following you.  I believe you are on the right track and hope everything works out where you can bring this to the next CIRCULAR level.

From what I saw in the linear form the runner magnet starts to pick up speed just like magnets in a rail gun. 

Think of the power of two 4.5 inch diameter runner magnets mounted like you have illustrated and rotating fast.  It would be awsome if the concept works.

In my last movie I showed a rotating turntable with two 4.5 inch magnets mounted on it.  My power ring idea did not work out. --- So---Next I am going to try some sort of outer cylinder around the rotating rotor turntable with a staggered track configuration of magnets lining the walls.  Check out the rotating cylinder wall magnet configuration in this movie.

Note:  I see a shadow of a fast moving arm just as the cylinder rotates-- Question if it was given a hand spin leading to wrong assumptions.

Tom,

I agree, there is something fishy about that video. What he is talking about when he says something about using one set of magnets to pull another set through the sticky spot is a valid idea. However, every time I see one of those video and 90% of it is about a better tomorrow or some political/ philanthropically idea rather then the scientific break through in technology and how the mechanics work I think its just a hokes or some school project to make a convincing video for a class. It sounds too much like a sales pitch then scientific presentation.

I believe it will work this way:

When the rotor magnet is approaching the stator magnet it meets a weak, and gradually stronger magnetic field, over a relatively long distance, as it approach further. The drawback however, is where the rotor magnet is going to leave the narrowest end of the stator magnets. The sum of attraction forces is namely the same in both directions, but it is weaker and over a longer distance at the widest end, and strong over a short distance at the narrowest end of the stator magnet.

Well, I have learn that if a magnet is going to continuously push another magnet more in one direction than in the other, the magnetic field must alter - as it doesn't in a permanent magnet. The tricky part is to find a way to close this loop, find a way to alter the magnetic field without consuming energy that will force the rotor as much in the opposite direction.

How do you solve that? I believe this is one of the questions you want some answers to. I have unfortunately not, but I know only the principals about how it must work, to work:

When using permanent magnets as power, it is no problem to alter the magnetic field from strong to weak - it is just to alter the distance in one end as shown in your drawings. The problem however is where the magnetic lines lays in that configuration. The magnetic field will always be strongest and with continuous strength all the time at the narrowest point forcing the rotor magnet to attract to this point.
In an altering magnetic field caused by supplying external power, the magnetic lines can be arranged quite similar, but the field where it used to be strongest is suddenly weaker, or gone, in an appropriate moment - just where the rotor magnet has passed the strongest field of the stator magnet. So there is suddenly no force to pull the rotor magnet back in the opposite direction.

So, if one are able to alter or weaken a magnetic field, when appropriate, without using energy and alter the magnetic path, the solution to make a real permanent magnet motor is present. A material that will help to solve this, have the properties to absorb magnetic field without altering the magnetic path close to it where this material is present.
A material that will cast a magnetic shadow. Magnetic materials are not an option.
