In a recent AC vs DC motor thread Daniël posted up about the motors used in his awesome boat project, and Paul was able to pull up some of his photos.
That got me curious to see and read the rest of the boat thread and from there i found that Major had identified the motors as having 2 Turns per coil, and that he had actually invented and made a small fortune on this multi-layer winding back in 1979, see post here.
Now i'm curious about these winding--was there a patent on the multi-turn winding, i would be interested to read it and probably others would too.
