For 2 years Japan has been selling the new extremely efficient electric motors within their country. What makes them efficient is that the coil is on the outside and the magnets on the shaft are positioned so there is no seize point anywhere in its rotation.
There is also a working design for passenger bus motors along the same line.

If this set up can apply to a generator seems to defy Newtonian law but if Ke energy is not utterly fiction, who knows, it might work.
Hey I'm no Tesla but maybe someone here is.
