I have always wondered why no one ever makes  permanent-magnet-motors,  by copying the wheels-with-scoops-propelled-by-water  that are used in hydro-electric-plants,  the Pelton-Wheel ( https://en.wikipedia.org/wiki/Pelton_wheel ),  I would copy and post an image, but I don't understand copyright rules .

(  The difference between a waterfall,  and a magnetic-field,  being that a  magnetic-field has a limited range,   although,   I assume they use a narrow high pressure stream of water  )

Now,  look at the diagram I have posted below  'Hollow Dome.JPG',  the magnetic-field  emanating from the hollow section,  should be close to being flat,  so,  that should minimize the chances of getting caught in a merge-point,  from that part of the dome anyway .
---------------------------

Different subject

Magnet-Motor-1
I have made a correction to  magnet-motor-1,  to minimize the effect of the only merge-point in this motor,  that being the last magnet on the wheel to try and detach away from the strongest part of the stator .
     The  blue-arrow,  shows how thick, the thickest part of the stator should be,  and the rest is crossed out .

Magnet-Motor-2
In the Side-View diagram,  posted below,  I have added a large  blue arrow  showing the direction of travel,  of the Moving-Magnet labelled 'A' .
  Also, you can see I arranged the stacks/rows of  Stator-Magnets labelled 'B',  especially so that at any one moment in time,  Moving-Magnet labelled 'A'  is only affected by one potential merge-point, which would be cancelled out by the effect of 2 other stator-magnets acting upon  Moving-Magnet labelled 'A' .

When I look at my diagram of the Magnetic-Sled( LARGE-FLAT-MAGNET FLOATING ON ARRAY.JPG,  posted on this thread ), gliding over arrays of tiny magnets spaced apart from each other,  I start to wonder if that, or a different version,   could function as a  magnet-motor,  especially if it was arranged in a suitable circle.



   I have just realized that my  'magnet-motor-2'  ( my previous post shows the direction of movement ),     that the design of the  'individual stators'  in that  magnet-motor,     could be used to make the Magnetic-Sled mentioned above, gliding over arrays of tiny magnets spaced apart from each other,  to see if it could function as a magnet-motor,  like a reversal of magnet-motor-2

Below is the diagram of  MAGNET-MOTOR-3,  the sled is modified to make a horseshoe-magnets,  the horseshoe-magnet  levitates  above the array of small-magnets,  and based on the effect of MAGNET-MOTOR-2  is propelled along .

This one is very cool.  It uses solar cells to generate electricity to propel a diamagnetic train.  Not sure how many watts are required to keep it moving.  Wonder if some type of energy harvester could be used instead.

Explanation: this is a museum model to demo how a magnetic levitation train works. It takes advantage of four design elements:
(1) an inhomogeneous magnetic field that repels a diamagnetic plate so that it floats about 1 mm above the track,
(2) the shape and size of the diamagnetic plate is optimized in a way so that, with the specific permanent magnet in use, the train is guided even at bends along the track without touching the surface,
(3) a linear motor using a sensor coil and two drive coils to move the train model forward,
(4) solar panels which convert solar energy into electrical energy.

The track consists of three rows of neodymium platelets which are aligned in a way so that the two outer rows are inversely polarized to the middle row on which the train model moves. As a diamagnetic material a thin layer of pyrolytic graphite is used. Pyrolytic graphite is a material which is neither ferromagnetic nor paramagnetic so that the repulsive properties of diamagnetism become effective. The linear motor senses the slight disturbances in the magnetic field between the neodymium platelets of the track thanks to the sensor coil. It switches between the two drive coils to that the model train can move along. The little electricity which is needed for the linear motor to operate comes from the solar panels on top of the model train.



interesting use of low input power there.
sensors and relay switches, low power. wonder how much would be needed for a 500pound or even 50 pound weight, less even.

looks like artwork for a table centerpiece.

make a interesting train set if you could create one with loops and maybe even track changers!
it would sell well to someone into model train sets, from the future!
or just make one to not have a typical train set.

who knows, you might have industrial uses for the floating system.
get it to cycle and it could perhaps store up some energy with coils and magnets to be useful.

Magnet-Motor-3

The diagram below,  includes a  top-view, in order to show the arrangement of the stator-magnets of Magnet-Motor-3  .

(  The stator-magnets are arranged in a particular pattern, so that at any one time, the merge-points in one row, will be offset by the lack of merge-points in the other 2 rows.  The same pattern,  that was used in my motor-magnet-2  )
------------------------------

  Regarding   All-Permanent-Magnet-Full-Levitation,  and,  Solid-State-Free-Energy-Generators

  If  Solid-State-Free-Energy-Generators don't  function successfully( don't achieve overunity ),  maybe they should include  an  All-Permanent-Magnet-Full-Levitation  component,  to provide the initial oscillation that is amplified in the coils etc.
     The     All-Permanent-Magnet-Full-Levitation  component  that should be chosen,  should be as unstable as possible( even though the levitating magnet never touches any other object ),   but the more stable  All-Permanent-Magnet-Full-Levitation  designs may vibrate at a higher frequency .

    My less-stable All-Permanent-Magnet-Full-Levitation designs
    http://overunity.com/16295/all-permanent-magnet-complete-levitation/msg469597/#msg469597
   
    My stable All-Permanent-Magnet-Full-Levitation designs
    http://overunity.com/16298/my-levitators-and-bearings-and-other-designsinventions/msg469748/#msg469748

    Or, to increase the frequency obtained from  All-Permanent-Magnet-Full-Levitation  even further,  any of my  All-Permanent-Magnet-Full-Levitation designs  above,  could  easily be modified,  so that the levitating  permanent-magnet,   is pressed in between,  2 devices that make it levitate away from each other.

So now I am faced with the problem how do I make the levitating permanent magnet in bismuth spin without touching it.  If you throw a voltage across the magnet it will spin Homopolar motor https://www.youtube.com/watch?v=De6VdKA3IH4 but how do I induce a spin without actually touching it and need to be able to do this from inside a vacuum, so I need to generate the current in the vacuum (Solar, crystal battery etc) or outside and use induction.

To cause rotation in a vacuum

A difficult way.  This version  https://en.wikipedia.org/wiki/Nichols_radiometer  of a  radiometer,   works in much higher vacuums  than used by other radiometers,  because it functions via a different method.   I think it works directly of the effect of photons striking a surface,   but since it does not contain a  Fully-Levitating  component,  it does not rotate. 
But you could use the principle by which it works.
 
Maybe you could use pulses from a strong electromagnet, or just by rapidly moving a strong permanent-magnet near it.

Or, use an  electrostatic-charge,  attach some very-very-thin plastic or fibers to the levitating magnet,  and use something with a  strong  electrostatic-charge to move it.
(  an electrostatic-charge can work through plastic or glass containers, which are filled with things affected by an  electrostatic-charge,  like thin fibers,  although I'm not sure if it works through both plastic and glass  )

There would probably be lots of other ways .

(  It's strange that your laser idea won't work in a vacuum, although that is the same reason a  non Nichols-radiometer,  won't spin in a high enough vacuum.
    But,  lasers  emit  electro-magnetic  radiation,  and you are pointing your laser at a magnet, so you'd think it might be able to make it spin  )

I think the reason you want to do this, is to see how long it would spin for ,  but it would be affected by all sorts of things.  There are constant micro-tremors from the earth,  and various other things .

Thanks I think the electrostatic propulsion idea is interesting.  I tried a coil and 9v around the Bismuth with no effect.  Laser doesn't work through the glass jar I am using for my vacuum chamber. If I take a magnet and drag it beside the jar it rotates but I can't get it to spin...  Maybe try a plastic solenoid and try and flick magnet corner.  I do think it should spin longer in a vacuum but I am not sure how much.  The magnetic poles I guess could be adding drag, I am  not sure if the diamagnets are stopping the spin as well.   I guess I could try and shield from the poles with MU metal or something around the jar.

Below is  magnet-motor-3.2 ,   and  magnet-motor-3.4 .

So with these two updated designs,  there is no longer a need for the slightly difficult pattern of  stator-magnets arrangement,  because now there are three  moving-magnets  attached together,  to form one moving-component.   
   The intended effect of attaching together 2 or 3   moving-magnets is so that  merge-points encountered by one moving-magnet  will be offset by the lack of merge-points encountered by the other  moving-magnets .

From my previous post,  I'm not sure if  magnet-motor-3-4  would function, but it's an interesting design,  not only for reasons as to why it would not,  or would function,  but also as to what sort of levitation effect it would have .

   Below, I have re-drawn  magnet-motor-3-2  to use more conventional  shapes,  and that is called   magnet-motor-3-2-5

  (  not that I think any  magnet-motor  would actually function )

  I'm   guest1289,  this is my other account,   for other things I'm doing  .

  Could the stators in  magnet-motor-3.2  that I just posted,  be replaced with simple metal-plates,  thereby making this a viable engine for railways .

  (  Also,  could someone design a  magnet-motor using a row of  donut-magnets,  exploiting the well-known neutral-zone  in the donut-magnet,  I can't think of any way  )

Why are you using 2 different accounts on here?  Do you not know that this is against the Terms Of Service that you agreed to when you signed up for this site?

I suggest that you eliminate one of these accounts before the Admin eliminates both of them.

Thank you.

   I definitely did not know there's an actual rule( terms of service ),  stating that you cannot have more than one account.  I did wonder though .

   I do have a very valid reason for having to use 2 accounts,  I won't detail it on the forum,   but there must never be exception to rules,  or the site won't work  etc .

   The mistake I made is that I actually stated that I am guest1289,  but again,  I didn't know it's against the rules .

   There are probably a lot of people on here that have 2 accounts,  for all sorts of reasons,  but of course they don't state that they have 2 accounts,  so it won't be a problem for them .

   It will affect me,  no longer being able to use 2 accounts( and stating on my posts that I am the same person as another account ),  but obviously I will no longer be able to do that .

Magnet-Motor-1-1
 Below, is the new diagram for this motor,  and the area labelled   'effect-point' shows how I'm trying to re-design the only merge-point  in this motor. Basically, I'm trying to induce some more  magnetic-attraction-strength into the weak/thin  side/end of the merge-point  by using  the strong/wider  side/end of the merge-point.

    My drawing skills have again failed, because I have not fully drawn what I wanted to draw.  This needs an artist .

  (  In the diagram,
      -  At the  'effect-point',  more of the weak/thin  side/end of the merge-point  needs have more of the strong/wider  side/end of the merge-point closer to it.
      -  The stator needs to more accurately get wider and wider.    )

  So, for this particular design, I think the stator would not be magnetic, it would just be metallic .

   The options for this type motor are infinite.
   ( I thought I had invented this motor 1 year ago, I can't go into more detail here.  However, some months after I invented it, without having drawn it, or discussed it with anyone, I saw a diagram on the internet which resembled my idea, but I did not check if the component that resembled my idea was actually a stator, and I did not read any details about it, I don't know if it contained a written description.  I have not been able to find that diagram since.  But last night, I found another magnet-motor pre-dating my motor,  which although does not work in the same way, it does contain a similar component.
-----

  My-Fly-Wheel-Device
  Have a flywheel using a passive-magnetic-bearing instead of an axle, and house it in a vacuum,  use the minimum electricity possible to first get the flywheel moving from a non-moving status, and then speed it up to a suitable speed,  then,  using a totally-frictionless  electricity-generator design incorporated into the device, generate-electricity,  and use it to keep the fly-wheel spinning.
   Keek in mind the flywheel would only be started up from it 'non-moving' status once, in the lifetime of the device.
   The electricity-generator design could just be magnets moving past a perfectly-smooth single electrical-cable loop,  and if needed, there could be much smaller cables to drain of any eddy-currents. ( of course this electricity-generator design would generate much less that other designs )
