DEFINITION

Classification: 322/66

(under subclass 63) Subject matter wherein the plural field windings include compensating windings.

(1) Note. Compensating windings are windings placed in slots in the pole faces of the generator pole pieces which produce a magnetomotive force equal and opposite to that produced by the armature and so prevent field distortion.
