Shunt generator
A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation.
Generator field connections
A shunt field may be directly connected across the armature terminals in parallel with the load. Where the machine has a series compounding winding, the field may be connected at the armature side or load side. The different connections give different voltage regulation characteristics on load. So as it is connected in shunt it has constant characteristics.Characteristic
Current in the field windings of a shunt-wound generator is 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.There will be a small armature voltage drop on the load, which will be reflected in the voltage applied to the shunt field. The output voltage in a DC shunt-wound generator drops slightly as load current increases because of the voltage drop across the armature resistance.
