No Bemf Motor

I designed this no Bemf motor quite a while ago and thought you may find this interesting. This motor develops a scary amount of torque for a relatively small duration input because it utilizes two poles of the rotor PM's in the same instance. In figure 1 on the lower left we see what is basically a 120/12volt transformer with the sides cut off to form an "H" shaped inductor. This inductor is between the opposite poles of two of the rotor magnets lying on a green line which is the bloch wall of the two PM poles. The bloch wall is a point where two magnetic fields meet, it is also a point where there is no polar magnetism it is a impolar region. Each PM has it's own bloch wall and between each PM a bloch wall is created designated by a green line. If this inductor is energized it is simultaneously repelled from the blue south pole and attracted to the red north pole.
Next in figure 1 to the right is another "H" inductor on the bloch wall of one of the rotor PM's. We can see that the PM field will couple to the inductor but the field will not enter the inductor windings because this is not the shortest magnetic path back to the PM's opposite pole, as such the inductor can produce a magnetic force on the rotor PM's but the rotor PM's cannot induce a current in the inductor windings. This means there can be no Bemf as there is no generator function acting on the inductor windings or better stated the PM field cannot cut the inductor windings producing a counter emf.
In figure 2 the two inductors bottom and right are shown having there poles designated by a blue(south pole) or red(north pole). The inductors are only energized within a small sector designated with (on-off) which roughly corresponds to the bloch wall between each pair of rotor PM's. Therefore if one inductor was used this inductor would be energized four times per revolution of the rotor.
On a less technical note, I see many people continually doing the same thing with the same designs and expecting different results each time when Im not sure there can be any change in there results. I have found through research and experiment that it is very difficult to utilize the magnetic pole of a permanent magnet and come out ahead in any way, so why do it? It is much easier to utilize the bloch wall to produce a dual force, both attraction and repulsion in the same instance and not have to deal with Bemf. A motor should act like a motor in every way and a generator should act like a generator in every way to be effective. There is also the problem of inductive inertia and residual magnetism that is not being dealt with in current motors. You cannot swap polarities at register without substantial losses, it is much more effective to energize an inductor at or near the bloch wall and have the after effects of energizing the inductor accelerate the rotor instead of de-accelerating it. I would like to mention that this rotary motor was designed after reading a patent by Wesley Gary for an oscillating motor. I am pretty sure Mr.Gary knew many things our enginners have yet to learn.
