Spiral magnet motor

[Honk]

Thanks Honk.I understand this is the case for the magnetic wankel motor, but I'm more interested in actual complete spiral configurations of the stator and/or rotor.
I still think it should be possible to get such a thing running without the need for heavy duty power electronics.

I can't see this happening. The problem is that you can't store any energy for later use without electronics.
And you won't get back energy (like BEMF from the electromagnet) when passing the sticky spot by brute force.
The rotor magnet will be attracted to the electromagnet core material as well and this is a very good thing.
You must use electronics to make it work.

Can you or others recommend any free (Linux) software for calculating the forces (and flux) between magnets and also for CAD (ideally combined)?

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.

The prefered name for the spiral motor is Magnetic Wankel Motor.
You should google on these words for more information.
Myself I'm being involved in a very similar project, namely a Dual Induction Split Spiral Motor.

The Mikell motor is a strange beast. I don't think it is the same as yours.

Yes, you are right. It's far from my design. I went blind when "Spiral Motor" was mentioned. 
Anyway, the last sentence on the site tell how the motor performed.
"Anyway this motor does nothing except it reduced my bank account. The cost for all magnets was about 500 EUR."
It performed no better than a statue....which of course was expected.
There is no magnetic gradient in this type of design, at least not what I can see.

Honk, I did not mean the donut (the "strange beast"). I mean the simple two-dimensional model (scroll down about one third on that page). That certainly doesn't cost â,¬ 500.

It says on that page:
"Do you know if there are other working models?"
A Yes. There is one in France that I know of that has duplicated the galaxy unit and it works.
At first it didn't because he coiled the legs of the galaxy to tightly but after I corrected him and he re-did it then it worked.

So I'm just curious whether anybody has heard of or tried that simple galaxy-model. That won't cost more than â,¬ 5 I guess.

Here it is. The only really working overunity spiral motor, aka The Magnetic Wankel Motor.

The others you pointed out have probably never worked and maybe the inventer was to ashamed
to admit this and continued to push it as working good without having a real device to show.
If there is no proof other than words the device is probably not working either.
