Generator separately excited by battery Self exciting generators Series on left, shunt on right. 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 is therefore self excited).
Description: A self-excited shunt-wound DC generator is shown on the left, and a magneto DC generator with permanent field magnets is shown on the right. The shunt-wound generator output varies with the current draw, while the magneto output is steady regardless of load variations. Page 196 Main Wikipedia article: Excitation (magnetic)
A self-excited shunt-wound DC generator is shown on the left, and a magneto DC generator with permanent field magnets is shown on the right. The shunt-wound generator output varies with the current draw, while the magneto output is steady regardless of load variations. A separately-excited DC generator with bipolar field magnets.
Consequent field, four-pole, shunt-wound DC generator Field lines of a four-pole stator passing through a Gramme ring or drum rotor. In the early years of generator development, the stator field went through an evolutionary improvement from a single bipolar field to a later multipole design.
Since an armature is wound with coils of wire, a magnetic field is set up in the armature whenever a current flows in the coils. This field is at right angles to the generator field and is called cross magnetization of the armature. The effect of the armature field is to distort the generator field and shift the neutral plane.
A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit. It is typically used to divert current away from a system or component in order to prevent overcurrent .

Universal motors' field coils are series wound with the rotor coils and commutator. Equivalent circuit. Not all series-wound motors operate well on AC current. [4] [note 1] If an ordinary series-wound DC motor were connected to an AC supply, it would run very poorly. The universal motor is modified in several ways to allow for proper AC supply ...
