Types Of Dc Generator Separately Excited And Self Excited Circuit Globe Dc generator types: dc generators are mainly divided into three types based on their field excitation methods: permanent magnet, separately excited, and self excited. self excited generator : a self excited dc generator uses its own output to power its field coils, which can be arranged as series, shunt, or compound wound. A self excited dc generator is the one whose field winding is excited by the current from the output of the generator itself. depending upon the connection of field winding with the armature, the self excited dc generators are of three types −. series generator. shunt generator. compound generator.
Classification Of Dc Generators Self Separately Excited Series Separately excited dc generators . an external dc source (e.g., battery) is used in this system for energizing field magnets. as the rotation speed increases, it can provide a higher emf and voltage in the output. the circuit diagram for the separately excited dc generators is illustrated in figure 3, and the symbols are as below: i l = load. Self excited dc generator is a device, in which the current to the field winding is supplied by the generator itself. in self excited dc generator, the field coils may be connected in parallel with the armature in the series, or it may be connected partly in series and partly in parallel with the armature windings. the self excited dc generator. The dc generators are normally of self excited type. also, read characteristics of separately excited dc generator. armature current, i a = i l. terminal voltage, v = e g – i a r a. electric power developed = e g i a. power delivered to load = e g i a – i r = i e – i r = vi a self excited d.c. generators. Self excited series dc generator. a self excited generator is one in which some of the output is used to provide current for the field. the self excited series dc generator has the field winding in series with the armature; thus, the armature current, field current, and load current are the same. figure 12 shows the arrangement.

Self excited d.c. generator. shunt generator, series generator, compound generator. let us check out the characteristics and performance of these generators. characteristics of separately excited dc generator : in a separately excited dc generator, field windings are energized by a separate external source, rather than using the same supply. 2. shunt wound excited generator. these types of dc generators have field windings that are coupled in parallel with the armature conductor, as shown in the figure. in shunt wound generators, the voltage across the field is the same as the voltage across the terminal. in this, r sh = resistance of the shunt winding.
