If you split the stator segments into 3 segments instead of 2, you will not have 2 rotor arm magnets going through the sticky spot at the same time. 3 rotor magnets will be providing rotational forces each time 1 gets to the rough place.

I don't think the number og rotor magnets have any affect. If the rotor will rotate with 3 magnets, it would run with 4 or 2 magnets. The difference is the amount of reactive force and cogging. The interesting part is the result of the sum of force and counterforce in one revolution. If the magnets accelerate to a speed that overcome the sticky point, you'll have a perpetual rotation regardless of number of magnets. To achieve this, one or more magnets have to reduce its magnetical force when it passes the sticky point, and get stronger when this point has been passed. What magnet can do that without influence of some kind of external energy?
Iron parts? No, these will influence on the magnet itself and get stick to it.
A magnet will reduce its magnetic field by passing a shortcuted air coil. Is that the solution? No. The magnet will feel drag, or some resistance to movement at that point, and you will reduce the speed at the sticky point anyway.

If you can imagine a doughnut magnet, magnetized radially (Equivalent to an infinit number of magnets in the rotor). Make this magnet to spin, and you have solved the problem. The question is HOW?

There is no way possible to get past the sticky point by pure speed in this type of design. All momentum gained in the loop would get lost.

The essense of the Wankel is to design it to rotate using the minimum amount of added electric current going into the electro magnets.
The electro magnet should firstly attract the rotor into its area and then instantaneously flip the field to repel the rotor magnet into next loop.
The best magnets are made of Supermalloy and the activated window of the electromagnet must be timed to the minimum possible to avoid end spiral breaking.

My point was in the first place that if the rotor accelerated enough, the speed of the mass will for sure overcome the sticky point. In the second place, this cannot be done without adding ekstra energy. Then the question was simply where to get this energy from.

The Wankel: The little amount of energy you put in, will be at most the little amount of energy you get out. No matter the complexity, simplicity, or arrangment of electromagnets etc. The energy you put in will be the most you'll get out. The Wankel design is nothing more than a electromotor - in fact it seems to work pretty much like a regular brushless motor. But maybe overunity is not the goal?

Have you ever designed and built a Wankel motor of your own?
It seems like your just guessing here.

No matter the complexity, simplicity, or arrangment of electromagnets etc. The energy you put in will be the most you'll get out.

Most of the torque is created by the natural twisting force of the neo magnets, not by the electro magnets.
So how can you determine that I'll only get out what I put in?

The Wankel design is nothing more than a electromotor - in fact it seems to work pretty much like a regular brushless motor.

I have designed a couple of BLDC motors and also their controllers in my career. And I see no resemblence to a regular motor whatsoever.
In a regular motor all of the torque is created by the electro magnets continuously working towards the permanent magnets. Push and pull.
And when the motor increases in speed it will output Back Voltage. When the Back Voltage has reached the same level as the working
voltage that is feed to the motor it stops to accelerate. This is the regular motors rated RPM level.
When you load the regular electric motor you will lower the RPM and the Back Voltage vill decrease as well.
The difference in applied voltage and the generated Back Voltage divided by the internal resistance of the motor equals the current going into the motor.
Simply Ohms law. This is why a regular motor consumes more current when loaded harder.
I can tell you for sure that a Wankel does not operate in this way at all. You better study regular motors before comparing those two motor types.
No offense towards you. I just wanted to explain how it really works.

But maybe overunity is not the goal?

Of course OU is the goal. Otherwise I would not spend time at this forum!

Then the question was simply where to get this energy from.

The idea of the Wankel is to add a minimum of energy to keep the natural magnetic rotation continuously going on.
You can see it like a magnetic amplifier.
The torque of the magnets rotating is kept alive by a very small energy input.
The output is the sum of all torque x speed from the motor while the electro magnets are turned off.
Output = Torque x speed - input energy.
Of course the electro magnets will add torque while operating but this part is not OU.
