DEFINITION

Classification: 318/804

With controlled magnetic reactance:

(under subclass 799) Subject matter wherein the circuit connected to the primary member of the motor includes a controlled magnetic reactance.

(1) Note. The controlled reactance of this subclass type includes magnetic amplifiers, saturable reactors, and transformers having a winding in circuit with the primary winding of the motor wherein the winding reactance is changed as a result of the mutual inductance between this winding and

another winding of the transformer.
