(under subclass 44) Subject matter wherein the generator is controlled by controlling the structure of parts which form at least a portion of the magnetic circuit of the generator.
(1) Note. See Lines With Other Classes, "Nonelectrical Means Controlling the Generator" of the class definition for a reference to the nonelectric control means for generator structure which is excluded from this class.

3, for systems within the class definition where the generator has a moving generating means which may be the armature or the field structure which has a reciprocating motion.
57, for generator control under subclass 44 where the generator control means includes means for saturating the generator magnetic structure by means of a winding which is in noninductive relationship to the armature or field winding of the generator.
59+, for generator control under subclass 44 where the generator is controlled by controlling an excitation winding. See indented subclasses 59+, for generator control by means
of a variable length field winding. 89+, for generator control under subclass 44 where the generator is controlled by controlling the armature circuit.
