The Generator 57 FOUR TYPES In general, there are four types of direct currentproducing dynamos, or more exactly termed gener-ators, and these take their names from the methodof field winding or excitation. These types are:Series, shunt, compound, and separately excitedshunt. SERIES GENERATOR The stator or field of a series generator has a lowresistance winding, since the full line current passesthrough it. It is, therefore, usually wound with afew turns of heavy copper wire or strip. Since the Series Field. Mai Armature Main Fig. 20.—Connections for Series Generator current regulation of a generator is mainly dependentupon its field excitation, a variable resistance is placedin parallel with the field winding, as shown in theconventional diagram, Fig. 20. However, on accountof the very large current required for plating work,the series type generator is seldom specified for suchuse. 58 The Modern Electroplater SHUNT GENERATOR As the name implies, the field winding of theself-excited shunt type generator is shunted or paral-leled with the line circuit. Of necessity, this windingmust have comparatively high resistance, and there-fore a large number of turns of fine wire is wound Main jArmaiure
