(under subclass 13) Subject matter wherein the converter includes a dynamoelectric machine.
(1) Note. See the Glossary for a definition of Dynamoelectric Machine.
(2) Note. The dynamoelectric machine types commonly used as current converters include motor-generator sets and rotary converters.
(3) Note. Although systems involving motor-generator sets are generally classified in Class 322, Electricity: Single Generator Systems, in systems wherein there is significant conversion from D.C. to A.C. or vice versa, classification is in this class (363). However, the generic place for systems involving motor-generator sets is in Class 322. See the class definition, Lines With Other Classes, Motor Generator Systems in Class 322, Electricity, Single Generator Systems.
(4) Note. Since many of the problems of operation and control of dynamoelectric machine converters are analogous to the problems of operation, and control of motors and generators (e.g., starting speed control, excitation control, etc.), it is noted that analogous pertinent art is classified in the motor and generator classes. See search classes below.
