I have spent whole article to discuss the process to overcome the technical difficulties in designing an overunity motor. My conclusion there appears to be: It is impossible to build one which overcame the issue of inductance. Although electrical energy is saved by the elimination of Back EMF by replacing the attraction of electromagnetic coil and Magnet with attraction of electromagnetic coil and ferromagnetic material. However, to prevent the attraction between them from halting the motion of motor, the electromagnetic coil need to frequently switched. As the speed of motor increase, the electrical energy spent in fighting the inductance of electromagnetic coils increase, so the effect of reduce the waste of electrical energy decrese as the speed increase. What is the solution for this problem?
The answer of this design problems lies in a phenomena known as ‘Parametric Power Conversion’ which a coreless electromagnetic coil would attract an iron core into itself, lead to an instantaneous increase of electrical energy in the electromagnetic coil. Therefore what we need to do in the design of overunity motor is by placing corelss electromagnetic coil as the stator, and a ring consists with material that is ferromagnetic alternating with material that is non-magnetic as the rotor. Then we need a circuit breaker to demagnetize the electromagnetic coils to prevent them from holding the rotor ring. If we can overcome the technicality of letting the ring to enter and depart from the electromagnetic coils freely, while find a way to transfer that angular momentum to do useful work in outside; then the motor require little or no electrical energy to operate(because the lost in electrical resistance in the electromagnetic coil would be compensated by Parametric Power Conversion). We got kinetic energy from electromagnetic coils for free. We essential continually borrow the kinetic energy from the bonding which held the stator static.
How to overcome the technicalities of letting the ring to enter and depart from the electromagnetic coils freely, while find a way to transfer that angular momentum to do useful work in outside. We essentially need the rotor to float in the middle air, while extract kinetic energy from it. How is it possible?
There are two approaches to this technicality: 1. We can think in the direction of using special physical mechanism to hold the ring in mid-air and use friction to transfer its kinetic energy like bearings; 2. We can separate the mechanism which hold the ring in the mid-air and the mechanism to take the kinetic energy out of the ring. One mechanism for latter that naturally come to mind is attraction and repulsion of magnetic/electrical field. For instance, we can use the magnetized metal in the ring moving between the electromagnetic coils to attract the ferromagnetic metal of the shell which is supported by a central axis. However, caution need to taken to avoid the mechanism to harvest kinetic energy of the rotor from diluting the effect of electromagnetic coil on the ring.

How to resolve technical issue in an Overunity Motor Design
One direction to create an overunity device is by looking at various natural phenomena that we can take advantage of, for instance: The attraction of Iron to Magnet. Then next is to see how we are going to use that phenomena to do what we invent it to do. One direct application we could immediately thought of is motor. Since motor require an electrical charge to magnetize it to move, then it is natural if we can replace the role of electromagnetic coil and magnet with iron and permanent magnet. However, if we start at the very beginning we may notice a potential problem: How is possible to move continuously given iron would attracted to the magnet, then attached into it? In a sense, this phenomena is discrete by itself; therefore it is natural to apply it to invention that require discrete movement. Now suppose we ignore that and focus on fitting it into a motor. The purpose of a motor is to rotate continuously without break, thus it is contradictory to the nature of this phenomena. It is thus not a best fit and methods need to devise to alleviate the inherent mismatch of this phenomena when applied to continuous motion in motor.
When we attempt to alleviate that issue, we may just have simply overlook another issue: A motor’s motion is made possible because the electromagnetic coil switch its polarity periodically(That create a set of problem known as Back EMF which waste the electrical energy in fighting against the inductance in electromagnetic coil.). Thus we could similarly infer that just iron and permanent magnet may not be suitable for this purpose since there is no way to change the magnetic polarity of a permanent magnet.
If we dissect the contradiction between ‘discrete’ nature of that phenomena and continuous nature of motor’s motion carefully, we notice that the discreteness of movement in the phenomena is also caused by pairing between permanent magnet and iron. Obviously, there seems to be no replacement for the iron or any ferromagnetic material. The problem is caused because of permanence of the magnetic field in the permanent magnet. If the magnetic field is adjustable, we could thus kill two birds in one stone: To overcome the discrete nature of the phenomena(creating a bridge between two apparently contradictory thing), and also increase the similarity between the invention and existing motor. The logic is that existing motor works by changeability of the magnetic polarity of the electromagnetic coil, so maybe we need to mimic that when we want to make a motor.
However, we shouldn't ignore that the reason motor require changeability of the magnetic polarity is because they have used permanent magnet in the first place. Permanent magnet is noticed by its invariability of the magnetic polarity, i.e. that would favor discrete movement but not continuous movement. Thus invariability of the magnetic polarity of permanent magnet is what caused the changeability of the magnetic polarity of electromagnetic coil is needed. If there are ways to replace the function a permanent magnet play in the motor, then it may also need that the changeability of the magnetic polarity of electromagnetic coil may no longer be needed. Or at least the variability of the magnetic polarity of electromagnetic coil could be reduced, thus reduce a percentage of energy lost due to frequency switching of magnetic polarity in the electromagnetic coil.
The above is just a blind guess since we never take the heart to compare the role of permanent magnet to the electromagnetic coil, along with the role of iron to permanent magnet. Either permanent magnet of electromagnetic coil is for the sake of producing a magnetic field, while either iron or permanent magnet is for the sake of responding to the magnetic field of the former. In the former comparison, electromagnetic is advantageous compared to permanent magnet due to its changeability of magnetic pole at the cost electrical energy wasted; In the later comparison, iron is advantageous to permanent magnet because iron would always produce an attractive magnetic field toward any magnetic field emitting object while permanent magnet has a fixed set of attracted and repelled object. Moreover, the strength iron’s responding magnetic field toward the magnetic field emitting object depending on the strength of magnetic field that object emit, while the strength of
permanent magnet’s magnetic field is fixed. The last comparison may not be so important since the added variability of the strength of magnetic field of iron doesn't seem to matter in the design of motor.
Now we paired the best with the best in both pair then we come up with electromagnetic coil and iron. After the above discussion then obviously we could paired these two variability brother together. The result is a motor with lesser Back EMF than traditional motor design with permanent magnet. However, we still need to overcome the discrete nature of iron-magnet attraction. The mechanism is exploiting the changeability of the magnetic polarity of electromagnetic coil. To make a discrete movement continuous, we also need to discretize the magnetic field of the electromagnetic coil. Notice that this 'solution’ also introduce the same set of issue as traditional motor: The faster the motor, the greater the Back EMF. Thus that is NOT a complete solution to the problem in traditional problem. This could be foreseen when we analyze the problem of traditional motor and attempting to invent an Overunity Motor via the nature of interaction between magnetic field in electromagnetic coil and the iron. The trouble is that the responding magnetic field of iron is COMPLETELY dependent on the electromagnetic coil, there is no way to turn off the responding magnetic field of the iron.
