If we have a generator like the 'N' machine which gives us no drag when we take current out of it, we ought to have a motor effect. A "free energy" motor would have no back-EMF at all and all you would have to do would be to supply current to it. In November 1952 Wireless Engineer "A Novel Form of D.C. Motor", the Germans had invented such a motor during the war. In it, a [fixed] copper spiral had two iron pole pieces rotating around it with an axle going through the centre. A brush on the inner end of the copper spiral and one on the frame supporting its outer end fed current to it. The current on the inside [end of the spiral] goes into the axle and is taken out via a brush on the right handside (Fig. 15). This motor has no back-EMF.

Muistuu mieleeni kokeemme Mariskoolissa,(Penttisen pajalla) jossa lipee liuokseen upotettu rengasmagneetti ja sen ulkokehälle asetettu putki elektrodi sekä keskelle asetettu tappi elektrodi, ja niiden väliin muodostuva vesipyörre.

Another article that reinforces Tesla´s ideas is "A Laboratory Self-Exiting Dynamo" by Lowes and Wilkinson, reprinted in Magnetism and the Cosmos, in 1965, by NATO Advanced Study Institute on Planetary and Stellar Magnetism in the Departments of Physics and Mathematics at the University of Newcastle upon Tyne.
On page 124, they mention that "a more efficient geometry was found, so efficient that the dynamo would self-excite in a completely homogenous state (i.e. with no insulation) at a much lower rotor speed than was believed possible."
Their design is based upon conducting spheres or cylinders rotating like eddy currents in a conducting medium (also see page 126 of Sci. Amer., "The Source of the Earth´s Magnetic Field," 1979).
