thanks for the information this is a really interesting project
Kind Regards

Hi DreamThinkBuild
Im afraid that the result will be the same as if your static magnetic disc isnt there at all. The reason is that the repulsion will be the same in both direction's-both on aproach and on leaving. So the net result is zero. I do believe that PM's can be made to provide a rotational force,but as of yet,it hasnt been done. But it's only a matter of time befor it happens-just like the heavier than air machines that would never fly.

Hi Mark,

Thanks.

Hi Conrad,

The idea is to reduce the input current to the prime mover while the coils are loaded. Whether it is efficient, I'm not sure, have to test and find out. Thanks.

Hi Tinman,

The reason is that the repulsion will be the same in both direction's-both on approach and on leaving. So the net result is zero.

It seems counter intuitive. That is the same thought I had and one reason why I attempted the build. I've done some tests with magnets where you can make a neutral plane from repelling/attracting magnets. The same thought came with this design. Could it be possible to create a neutral plane between the attraction of the coil and repulsion of the repulsor magnets.

I attached a picture of the neutral plane, this is from one of my magnet motor attempts. The magnets are all north facing around the ring with a channel in between. When a south facing magnet is placed in the channel attached to a arm it will move with very little resistance, instead of being pulled into the rings.

If you rotate the channeled magnet, keeping the axis aligned to the plane, you can create a vector where the magnet will be pulled from the inner ring but pushed from the outer ring. What is interesting is it will not move until you make a gate. Removing one inner and outer magnet will create a gate, the arm will move to gate. Put the magnets back and it becomes a static system again.

Hi Gyula,

You always learn something with tinkering, even if the device fails. The coils are actually electromagnet coils from Electronic Goldmine, they have a steel core. I have other magnets that you can just swipe by the coil and it will light up a bank of leds when rectified. I can get the air gap to about 3mm but it's still not enough with these magnets. Thanks for the suggestions.

Hi DreamThinkBuild,

Sorry for saying there have been bolts in your coils as cores but for a dynamic field change such rotary setups have, the steel core may still develop eddy current losses, for they are designed for much less frequent on-off operation. And also their copper losses may also be high for generating power but I fully understand they are good for the principle test, optimization should come only later if it proves to be worth doing.

Thanks for showing your other magnet motor attempt, very interesting. What if you use the Werjefelt principle on that setup? i.e. you remove as you say one magnet from both the outer and inner circles, you will have a stopping sticky point at that 'gate' for the South magnet moving in the channel, this sticky point is attractive and you would compensate this single point on the other end of the center shaft (away from all the magnets in the circles) with two facing repel magnets: one fixed to the shaft and the other one to a non-moving holder, both positioned such that they would repel each other at just the sticky point in the channel.  I know that a varying load force to the shaft would imply repositioning the distance between the repel magnets when they are just facing, but the principle could also be tested.
