Advantages and Disadvantages of DC Generator

Shunt-wound generator Shunt-wound DC generators are those where the windings of the armature and the field are parallelly connected. Because they can provide unchanging output voltage, we can use them for most lighting purposes, battery charging, providing excitations for alternators, portable generators, and so forth.

Characteristics of Series Wound DC Generator | Electrical4U

From the characteristics of a series wound DC generator, we can see that as the load increases (and therefore the load current), the terminal voltage initially rises. However, after reaching a peak, it starts to decrease due to the demagnetizing effect of the armature reaction. The dotted line in the figure shows this phenomenon, indicating ...

Wound rotor motor

Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates, the resistance can be decreased. [1] Compared to a squirrel-cage rotor, the rotor of the slip ring motor has more winding turns; the induced voltage is then higher, and the current lower, than for a squirrel-cage rotor.

Shunt generator

Current in the field windings of a shunt-wound generator is (approximately) independent of the load current, because currents in parallel branches are independent of each other. Since field current, and therefore field strength, is little affected by load current, the output voltage remains more nearly constant than does the output voltage of a series-wound generator.
