The problem lies in the applied magnetic field from the electromagnets.
In order to bring the motor into overunity the EM's, Toroid's or not, must equalise
the sticky spot by applying a nearly as strong field as the NdFebs and this is
of course impossible. The gain from the gradient slope is therefore lost at exit.
I can say by 100% certainty that the super puny field from a closed loop toroid
cannot bridge the gap in a magnetic Wankel. I don't need to spend time on this.

The toroidal solution in Steorn cannot in any way be compared to the needs of a Wankel.
Steorn has no permanent magnets next to their toroid's that has to be fought against.
A toroidal core has all of its field within the core and it's extremely weak outside.
This is the benefits of toroidal designs. Simply no magnetic EMI or losses due to airgaps.

Agree with Honk on this. 
The toroid core of the toroid/coil assy. would have to attract the rotor magnet away from the strongest magnet on the stator at the end of the spiral.  This would not be very likely to work.

A moving/switching magnet (on the stator or rotor) in my experience would be the most electrically efficient  way to get past the magnetic lock at the end of magnetic travel, with the least input power required.  Unfortunately the spiral motor is a design that is not well suited or structured for using this method of switching.

Honk, just to tell you I sent a PM.

@Honk: Don't give up!

Probably here you will find the clue?

Question: Why only one magnet on the rotor?

The more magnets are pulled/pushed by the spiral magnets, the bigger the force to overcome the sticky point.
You just have to make sure, that the distance between the magnets on the rotor is bigger than the distance between the first magnet and the sticky point magnet- to have only one magnet over the sticky point, while all the others are trying to push/pull...

Maybe the only reason why there is no OU rebuild is because no one tries it on a bigger scale- d>1m or even greater, to have as many rotor magnets as possible.

Or am i wrong?

By multiply the magnets, you just multiply the impossibilities. I have said this befor, but I'll say it again: If one magnet doesn't work, several magnets doesn't work.

The conservatism in magnets is the main and only problem. But that doesn't mean we shall stop trying and experimenting with them.
