While working on a setup for a different but related idea I did an intermediate experiment. You can classify this in the NO back EMF motor category.
The marinov motor ,the siberian coliu to be exact, is something that's only been refereed to once in a thread which I just revived:

Here's a condense history behind stefan marinov. Basically he met a Russian person who showed him the concept behind the split pole motor, he then added his own formulas to classical EM theory to account for this unexplainable effect. The effect was that a ring rotated and while rotating it produced an EMF AIDING applied voltage, so anti lenz in short.
The motor was horribly inefficient due to frictional losses and surface tension of mercury, which he used as brushing. So he was never able to let it self run. He then used his theory to design a concentric type setup with new magnets. He ordered the neo's from china which took many months back then. All the while hyping his theory and kind of "lieing" about the fact he had it self looped as he was confident of the new design before the magnets arrived. Needless to say the new design didn't work, one year later he committed suicide. I will not go into the anomalies of the suicide.
Since he passed away only a handful of scientists have experimented and wrote papers about it confirming the abnormal behavior. But the effect was always too small to call significant due to the "one loop" nature of it.
That brings us to now. Below I attached one kind of design of the siberian coliu. When dc is applied the ring spins and measurable voltage is seen increasing the current even further.
The obvious problem is the brushes. This motor needs very high currents to operate and windings can't be used to reduce effective supply current.
So I thought of pretty much the obvious.
1) make the magnets rotate
2) use many windings
3) drive it with AC
Since people tend to like the "change of flux" theory. When you rotate the magnets the field is so confined that there will be no changing flux and thus no induced emf. But when you apply current your magnet will rotate non the less. An image of this is also attached.
My experiment was very similar to that image. I took long steel rods with magnets at top and bottom far away from the "eye" and wound the "eyed" coil. I did this by pinning some nails to a board and winding the wires around the pins as guides.
When I applied current the magnet/core rotated 180° and stopped. When I reversed current direction it rotated 180° further and stopped. When you keep doing this you get continuous rotation. Due to the reason mentioned above you will see no reduction in applied voltage or in other words when spun manually no emf is generated.
And due to the simple design of this motor, high torque motors can be made easily.
All you need is two neo mags, 2 magnetic permeable bars and a rotor.
PS: An interesting side note about the rotor. It's actually also known as permanent magnet holder by many on the forum
