This device is the real self-running overunity?

Wow, maybe this device will work.

This is my understanding of the device:

Looking at the path of a small part of the magnet (treat the magnet as a set of many smaller magnets), you see that the relative rotational (tangential, not angular) speed between magnet and rotor are the key for this motor.

When the rotational speed of the magnet is greather then the rotor in a given point, that point will move into the coil from the backside. The BEMF/Lenz Law generates a force at that point on the magnet with one direction component directed in the rotor rotational direction. This force acts on the rotor via reaction forces in the magnet/rotor hole/axle, creating a positive turning momentum that accelerates the rotor. The same principle is valid when the magnet point has passed into the coil and also on return out of coil.

The law of conservation of angular momentum gives that the magnet will increase in speed if the rotor increase in speed and the BEMF is overcome.

When the rotational speed of the magnet i lower than the rotor, then the forces generates a negative momentum on the rotor. EDIT: Thus, to start, a motor is needed to overcome this "drag" and somehow speed up the magnet in opposite direction than the rotor. Maybe the coils can be powered/pulsed at startup to spin up the magnet.

So the trick is to give a large portion of the magnet a rotationall speed that is larger than the rotor speed.

To optimize and get the effect at a lower speed, the magnet diameter should be as large as possible compared to the rotor.

Agree, a picture would help .

First of all - hello and nice to meet you
Interesting concept. But this would mean, that the magnetic bearings are a must have - low friction. We really have to build some prototype to see what happens there at different circumstances.

First and formost: Thank You Mr. Walker for sharing your wonderful Idea with the world, although after reading some of the comments on this and other threads you probably wish you had kept it to yourself! Keep up the great research and out of the BOX thinking!!!! Hats off to you sir.

1. Which video? What timestamp ?

Upon closer inspection of "New Generator Video Part II 2-14-2010" (2:19) and more clearly the first video "Free Energy Generator- The real deal!" I realise I was wrong! In the the second video the obvious movement (later on from 2:19) is most likley inertia as a result of Wendall stopping the main rotor. But to me the greatest evidence that NO rotation of the disc magnets occuring is the first video. I slowed it down frame by frame and used the reflective part of one of the disc magnets to track any rotation in relation to the centre hub, for a time period when the camera position was relatively stable. When I measured changes from the first frame to the last, their was NO movement, down to the millimeter level. If the disc magnets DO rotate, they don't at slow speeds!

Therefore this design is nothing more than a simple magnet motor not capable of overunity. Yes?

@N Tesla: So you have made an exact replica? It makes sense that the magnets would spin at higher rpms, higher RPMs would create more flux buildup in the coils, and as soon the magnet entered the domain of the coil, the stronger of the two would grab the other. And the exit would have the opposite affect. It would be like trying to cut a hardened steel bolt with a pair of scissors, the scissors would have a tendency to move in the opposite direction!!!
