Magnet motor idea - again.

[Low-Q]

Hi,


Came up with this iea as a follow up for the "Notch-motor" I have posted earlier.


I have no time to explain things in detail, but for you skilled persons might have a though about how this "work".


The image is suppose to be animated... Doesn't seem to work from my computer...

The idea is this:


Cancelling the sticky spot by balance the rotor and stator between attractive and repelling force by use of the notch. Please see this video I made on youtube for how two opposing magnets can actually be neutrilized inside the notch. [size=78%]http://www.youtube.com/watch?v=obV4bUd4JmI&feature=g-upl[/size]


The same, but opposite will happen between two attractive magnets. However, the notch will then repel with the same force when the two magnets are meshed together.

In the video I tested only two magnet assamblies. Now I made three, just to check how the "rotor" magnet behaves between the two stator assamblies side by side with opposite polarity. I approached the "rotor magnet" towards the attracting stator assambly. By my surprise, the "sticky spot" between the two stator assamblies, the "rotor magnet" was forced towards the repelling assambly. That means that the rotor will be supplied with extra force in the direction I want, instead of being stopped and locked at a sticky spot.


I will build a circular prototype with speaker magnets. Cut them in half so one side has opposite polarity.

The animation below is suppose to explain in more detail what I observe with the current magnet alignment.

Does anyone have any idea if it is possible to simulate the above experiment in FEMM?


I hope it is possible to simulate with an eqivalent setup because FEMM works only in 2 dimensions...I just can't "see" how that should be done.


Maybe someone have Maxwell-software?
