Working Magnetic Motor on you tube??

[sveinutne]

Hi Jdo,

If you have a lot of knowledge in FEMM, you might help me with a new setup.

I am looking at the other approach. If we can get magnets that got a very narrow "beam", so there is no breaking before the two magnets are in line going through the center of the main rotor.

Then the force pushing the stator out will a split of a second later push the rotor around.

Yes the "stator" is changing direction in fig. #4 and #7 = #1.
I would like to simulate this in FEMM, but I am the worst person to draw this in FEMM. On the rotor the magnets need to be placed further apart, so the stator get space to move up and down without hitting the next magnet, so maybe the rotor magnets need to be placed 90Ã,°.
The stator is rotating very fast in #2 and #3, and slow in #5 and #6.
On the rotor I use two different types of magnets. One with a very narrow beam of magnetic field that will not break the rotor speed, only push radial on the stator magnet when they are aligned.
The other set of magnets on the rotor got the magnetic direction turned 90 degrees, so it can absorb the energy when the stator magnet is flipping around very fast. This will be fig #4 where the rotor and stator are moving in the same direction at first, but the stator is moving much faster, so it will buns back in the opposite direction in fig #5. The difficult part will be to build this so the stator magnet will come back at the right moment and hit the rotor magnet at the exact right position. But soon some idea will pop up with the solution to that problem too. What is more urgent will be to model this in FEMM so we can get a verification that this will give increased rotational speed on the rotor

I got some FEMM files that almost will do it, and a lua scrip that will step through it, but I need to modify the ââ,¬Å"statorââ,¬Â and the rotor magnets. If you got an email address I can send it to, then you can look at it and see what you can use.

The bearings binding at the right time is one way to get deceleration.

Aren't the aluminum dampers another way to get deceleration at the right time?

NO IT WAS NOT FOR REAL
OK,
When I run 180 degrees as I should in stead of 360. It all went back to normal. No OU:_|

I have no capable to use FEMM simulation well, so please try rotate the stator's pole position degree by degree... see what will happen then

I have used FEMM extensively to do simulations of magnetic motor ideas. You need to remember that the integrations in the software are deliberately set to = 0 so you will never get any energy gain in the software program. But it is a useful tool to get an idea of what the fields are doing.

Jdo300,

I manage to make the FEMM and lua script by myself, so you do not need to spend any time on it.

@fritz,

Someone earlier proposed a simple way to match magnets by placing them in repelling mode in a transparent tube and measuring the distance between them. He even checked with @alsetalokin what these distances are with his magnets. I tried to find the posting going back in this thread but couldn't find it. Not so easy to find what you're looking for sunk in so much other stuff.

@CLaNZeR, @Butch, @vipond50, @Nicolas Roger and others who have the replica made, could you please check if your rotors shows non-uniformity of pattern as mine does. I already said that here http://www.overunity.com/index.php/topic,3871.msg71821.html#msg71821but I'll repeat it.

I'd like to reemphasize the points @fritz made and my reply there:http://www.overunity.com/index.php/topic,3871.msg71709.html#msg71709 Proper form of the magnetic fields is of crucial importance in all these motors. Very hard to achieve. I'm looking now at one of my ostensibly (on the face of it) exact replicas of @alsetalokin's motor. Supposedly, when slowly turning the rotor the pattern one observes when the rotor is let go form a maximum to maximum (one feels these maximums when turning the rotor slowly by hand) should be of the same form repeated four times. Not so in my case. I'm observing the stator equally outstanding from the other two. If I start with a rotor magnet facing that stator the rotor bypasses the next magnet and bumps into the barrier formed by the third one. If I, however, continue and let go the rotor, further clockwise, from that barrier on the rotor stops at the fourth while it should bypass it if the pattern is to be preserved and so on. There's only one other place where the initially described pattern is observed, although slightly different (intermittent accelerations appear different). Now, that may be a significant problem. I've ordered more of these cylindrical magnets and will try to find matching ones to see whether this picture will improve. Of course, the stator magnets should be matching too. Wonder if someone else would be willing to check his rotor in this fashion.

@ Omnibus

It was Meggerman that posted about the test, with the two rotor magnets in a clear tube and measuring the distance between the two.

Al did this test, and his rotor magnets showed 30.5mm seperation.

@ Rob

I will do your requested test, when my N35's arrive.  I still have a feeling that Al's rotor magnets are not N42's, but weaker.  He even states, that he is sure that his stators are stronger than his rotor magnets.

Everyone really needs to experiment using different rotor magnet strengths.  This will make the difference between a self sustained run or not.  IMHO.

Cheers,
Bruce
