To quickly assess the difficulty of the text, read a short excerpt:

The direction of this current will be opposite to that producing the charge in the field and will itself tend to produce lines of force in opposition to the field. In other words, change from zero lines of force to maximum and back to zero will be retarded in the "shaded" or ferrule-enclosed half of the field. This will cause the magnetic flux to shift from the lower to the upper portion of the field at each reversal of polarity. Now currents are generated about the slots in the vane by the fie...ld flux the same as in the ferrule. These currents will produce fields of their own opposite to the main field, and will act against the main field and be repelled by it in the same manner as like magnetic poles.
But the sifting flux in the main field due to the ferrules is con- stantly moving upward. Therefore the vane is raised. The action is similar to that between fields and squirrel-cage armature in a polyphase induction motor.
