WebJan 31, 2024 · In dc shunt generator, the field winding is connected across the armature terminals. Field current flows due to the emf induced in the armature because of the rotation of the armature by the prime mover. When the armature just starts rotating a small amount of emf is induced in the armature due to the residual magnetism of the field. WebShunt generators were used where and main requirement is a constant voltage over a narrow load range. Applications are shunt generator: Secondhand for general lighting; Used to charge the battery because they can be created till give constantly output voltage; Used for giving the excitation to this alternators; In process of Electroplating
