H 02 P

 CONTROL OR REGULATION OF ELECTRIC MOTORS, GENERATORS, OR DYNAMO-ELECTRIC CONVERTERS; CONTROLLING TRANSFORMERS, REACTORS OR CHOKE COILS (structure of the starter, brake, or other control devices, see the relevant subclasses, e.g. mechanical brake F 16 D, mechanical speed regulator G 05 D, variable resistor H 01 C, starter switch H 01 H; systems for regulating electric or magnetic variables using transformers, reactors or choke coils G 05 F; arrangements structurally associated with motors, generators, dynamo-electric converters, transformers, reactors or choke coils, see the relevant subclasses, e.g. H 01 F, H 02 K; connection or control of one generator, transformer, reactor, choke coil, or dynamo-electric converter with regard to conjoint operation with similar or other source of supply H 02 J; control or regulation of static converters H 02 M) [4]
 

Notes

(1)

 This subclass covers arrangements for starting, regulating, electronically commutating, braking, or otherwise controlling motors, generators, dynamo-electric converters, clutches, brakes, gears, transformers, reactors or choke coils, of the types classified in the relevant subclasses, e.g. H 01 F, H 02 K.

(2)

 This subclass does not cover similar arrangements for the apparatus of the types classified in subclass H 02 N, which arrangements are covered by that subclass.

(3)

 In this subclass, the following terms or expressions are used with the meanings indicated: [6]
 

-

 "control" means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation; [6]
 

-

 "regulation" means maintaining a variable at a desired value, or within a desired range of values, by comparison of the actual value with the desired value. [6]
