Ren, I see what you are saying now and I would have to suggest staying away from using the magnets for both.

And why is that?

Ren, because of the length of the pulse time must be different to get passed the gates. If you turn off the power before the magnet gets far enough away for the core to attract the magnet that was thrown, you create a drag which takes away from your efficiency and your wheels rotation speed ability.

 You must use separate switching magnets and they must be kept out of the cores attraction and or repelling reach.

 You must remember that these motors take precise timing to achieve the best possible efficiency rate. You must eliminate all the drags you can. You should be able to eliminate all but a fraction of the one you get at center. You can not eliminate that one completely but you can limit its drag if precisely timed right.

Here is a example.

 If you look at the picture below, you will notice the yellow spots. Those spots are about where the power needs to start being applied and where the power needs to stop being applied. Note that it is not precise and only to be used as a example. Those lines need to be lined up with the center of the coils core. So you see, it is impossible for you to achieve any real efficiency by using the same magnets as the coil uses. The center and the draw back affect are actually longer then the actual length of the magnet.

 If you want to use magnets, they will have to be longer and placed away from the coils core attraction points.

 Take a magnet of the same size and strength and lay it on the wheel. Now move it along the wheel towards a magnet and mark where it starts to either repel or attract. Then take the measuring magnet away and mark a spot a hair further away from the magnet and that will be where you need to have the power of the coil shut off. Then measure the distance from the center of the magnet to the mark of shut off. Then measure the length of the magnet. You will see that the length of power needed is greater then the length of the magnet and by just using the magnet as a start and stop point, you will still be left with another drag point giving the motor two drag effects instead of one.
 You want the end of the shut off point to the start point to be at least a 2 to 1 ratio. Meaning, you want the distance to be at least twice the distance as the start and stop distance with out a load. But you want the end of the throw and the attraction point to over lap. Then you want to create a load that will only use only the distance of the over lap. The distance of the over lap is the energy to have to work with minus the energy used and the drag from the center of the magnet. If you can get that overlap to compensate for the energy loss you will achieve 100% efficiency and if you can overlap to compensate for the energy loss and still have energy left, you will achieve over 100% efficiency and what ever is over, is over unity.
 You must also note that the motor's efficiency rate is no good when coupled with a load. The loads efficiency rate must also be accounted for with your overall efficiency rate.

 So you see, it is not as easy as people think to achieve over unity with these motors. I think it can be done but it requires extracting energy from thin air to do. To do that, you must find out what energy really is. That?s a whole other topic.

 Hang in there and stay tuned because we are getting there.

There is one major flaw to this and that is that the coils core will eventually be magnetized with the polarity matching the polarity that it is being powered to be. The only way to stop that is by switching the polarity?s giving both polarity?s the same time of being polarized.
 With that said, the same concept must be used but in a reverse mode. This will take away some of the efficiency but it will add torque to the free movements. The area between points 1 and 2 as well as the area between points 6 and 7, would be the areas of free movement.

 This next picture is a updated version to match this concept. Please note that the placement of the triggers are not precise and they would have to be determined using the method mentioned in my last post.

The Bedini energizers I have built all have variable timing via a simple rheostat. This effects when the base is triggered to fire the power coils. I can see exactly what your are saying in your post and it does come into play with a traditional pulse motor. With the monopole you'll actually find the coil fires up to 23 degrees after the passing magnet. In this way it benefits from the repulsion of said magnet along with attraction of the scalar south of the next magnet.

This is not ideal for a motor designed for torque however, where I think the things you covered in your post  are more relevant.  A pickup coil can also be an easy way to alter timing manually. Check out Hoptoads page in "circuit setups for pulse motors" thread if you havent already. ;)


Here is a small vid of my monopole running on less than 50ma http://uk.youtube.com/watch?v=ma8Mas50W44

Oh and in regards to your core becoming magnetized over time, try a more suitable material. My core has been running day and night for months and retains no magnetism.

 Ren, thank you for that info but this is not a motor that I am attempting to build. I was only trying to help those that were trying to build these types of motors.

 I am still not done with my research on what energy really is. I am getting there and once I figure it out for sure, I will then start designing a way of harnessing it so it can be used in forms that we need it for.

 From what I have learned, I have a impossible task ahead of me due to the legal aspects of frequency use. I may have to wait for my kids to get out of school and on their own so that when I do build something and it lands me in prison, at least they will be grown and on their own.
