Oscillating sine wave LC tank magnet motor.

It is not a paradox.  It means that the system is non-linear.  Many systems are.  The common mistake that many people make is that they confuse increasing efficiency or increasing output with reduced input as a sign of over unity.  They invariably find that try as they might, they can't ever manage to get the system to the point that the absolute output energy exceeds the input energy, cycle by cycle.  There is always the "sticky spot" or its equivalent to overcome.  the predicted self-running machines only ever run down.

MarkE feels the inverse power effect is not a pathway to overunity. That may be if magnets don't fight back. Let's say we run ten magnet rotors and ten coils between two motors and load them with output instead of physical drag. I got over a ten percent gain in efficiency applying load. That amounts to a very serious advantage. I believe there's a chance of achieving "overunity" with a large enough scale up. I believe the advantage comes from the magnet increasing it's own strength to keep up with the frequency

Gotoluc demonstrates how increasing magnet strength increases the work a supporting power coil can do. When the rotor magnet grows stronger the greater the work the A.C. power coil can do for a fixed input.

I believe when the magnet rotor's slowed down enough, it begins to draw strength from the quantum plane to try and keep pace with the A.C power frequency. What's the upward limit to this power increase? Slowing the motor rotor with output drag may go over the breakeven point! As we press the motor for higher output the motor draws less power!

What truly puzzles me about this motor as a generator is that the coil windings would not normally generate any current or create any "Lenz Drag" the way they're oriented to the rotor magnet as a normal output coil would. Perhaps there is no Lenz Drag in the generator configuration for the synchronous kind of output with the coil facing sideways? The six "Mu Metal" stator walls must play an important, but not well understood, part in the motor's operation.

Running as a generator, the "Mu Metal" stator plates suppress the magnet field as the rotor turns.The magnet pulse is directed on the perpendicular, in and out, through the coil windings in an alternating fashion. This is the correct direction for the fluctuating field to generate current in the coil wraps. The question is; How can "Lenz Drag" effect the rotor when the coil wraps are slipping the field facing sideways?  The metal stator plates cause the alternating magnet field to pass through the coil windings on the perpendicular, but the coil has no way to influence the rotor back! If this kind of synchronous motor works backwards to generate power with no "Lenz Drag" we can shut our hazardous Nuclear Fission plants down tomorrow.

This turntable synchronous motor is more then just a synchronous motor it's a unique "Pulse A.C. synchronous motor".

As a generator it works a little like Dan Quale's "Lenz Free" generator , where we see an iron field interrupter:

Take a look at this short video on "Lenz's Law". Note in particular the orientation of the loop coil and the expanding and contracting magnetic field lines:
