Zero Air Gap Electric Motors could be improved?

Zero Air Gap Electric Motors could be improved?

Zero Air Gap Electric Motors could be improved?

Hello, I've been looking into online scientific articles and I was able to find a few ones about the subject. On these articles it is normally observed that the torque value of the motors doubles or even quadruples with the direct contact of the rotor and the stator while consuming the same amount of energy.

Some articles:

However, I really can't find anything but a few articles, so I'd like to ask around and see if someone can help or give an educated guess.

For example, I was thinking of making the rotor rotate just like a hypocycloidal drive. On top of that, I was also thinking on making the stator and rotor into gear-teeth.

But I'm not qualified enough to even guess how this would improve the performance of the electric motor, nor I feel confident on even attempting on designing such thing.

What are your thoughts on the subject?

A working simulation may be based on one ormorefalse assumptions.
For instance an induction motor depends on the slip frequency or slip RM for operation.
The slip frequency increases with the load

Ohm's law
Not just a good idea;
It's the LAW!
