Is this what you had in mind?

Hi Steven,

Fantastic build, long time no hearing of you. Any good news on this setup? What is the air gap size you managed to attain here?

I am sure Neo-X will be amazed by the pictures.  ;)

Thanks,  Gyula

Wow Im shocked... I dont know that theirs already build this and with a great 3d drawings.. Did you get an overunity? In my opinion theirs no need to use two magnet and two coils because using one big magnet and one big coil have similar effect. In other words my design is much simpler than yours but have the same effect..

I have not seen overunity with this principle. These designs do seem simple and straight forward but in reality it is far from simple. The main reason why I gave the magnet on the outside is so I can add or remove them when the motor is running, so I can get a good idea if the magnets actually add to the overall efficiency. And believe it or not but in most cases the adding of the magnets does nothing at all, meaning the fields of the magnets do not move. Only with very excessive input currents you see an rpm (thus torque) gain when the magnets are added. But at the same point the motor also starts to draw more amps. In my opinion it is still debatable if this approach has efficiency advantages. You might want to look into the works of Jack Hildenbrand. A few years ago he was very active on this forum with his motors - which were based on the same principle and were the best quality builds you will find around here. There was never any real conclusive results from his motors. He died about one or two years ago. The images below were some of his builds.

Here are some links. To bad Jack removed most of his posts:

Great job on the motors! I wish I were half the machinist you are.
You mentioned that you saw no difference in the performance between having the magnets attached and taking them off. This is normal for this type of motor. The magnets won't kick in until there is a fairly heavy load on the rotor. This is when there is an increased "pull" between the rotor and stator poles. In regular motors there is an increase in current draw which compensates for this. The increase current produces a stronger B field in the gap, which provides more torque.
When the motor is up to full speed, current draw is at a minimum. The little current that the coil produces is adequate for the job. That's why you can remove the magnets and nothing happens. Unloaded speed is not an indicator of motor performance in general.
What you'll find is that as you load the rotor, and the speed is reduced, your efficiency will start to increase. The more you load it, the more work the PMs will do.
Below (hopefully) is graph of a test I did with roughly the same type of motor you have. The input power remained constant throughout the test.
Otherwise you can find info on my motor here: http://hereticalbuilders.com/showthread.php?t=194&page=4
