I'm interested in the magnetic wankle motor. But when i search on it
i found that there is a rotary wankle motor too.

The right name should be Wankel, not Wankle.
This difference will affect your search results.

Here is an old thread about Neodymium magnet properties. Very enjoyable.

Honk is a tad self effacing. The important discussion on this idea starts here:

Have a visit.

Thanks a lot Honk 

Now i try to develop the mathematic model to find out the possibility of the motor
which i hope it to be useful to analyze all the possibility of the magnet motor before we risk
our time and money.
Unfortunately, I cannot find any practical formula to calculate the force between magnets.


Can u please tell me a formula that predict the force if we know angle of two magnets, strength of magnet (Tesla), and distance ?
And how to calculate the force of the rotor and stator while there are more than one magnet on stator that react to the rotor magnet?
Can we integrate the sum of each force and how?

More, i found some useful about magnetism and electromagnetic for beginner up to 50 books
I will post the resource if anyone needed.

Lucks

I have used this very good force calculator.

You just input the grade, shape and distance between two equal magnets to calculate the force.
In a magnetic wankel the distance between magnets is a gradient slope.
This means you have to calculate the distance from both sides of the rotor magnet to the opposite stator magnet and
then you subtract the lesser force value from the greater. Split the result by two and you have the gradient force.
Nice and simple.

Sometimes the magnetsales calculator have a long response time. I guess there is a lot of people using it.
