Series winding n. (Elec.) A winding in which the armature coil and the field-magnet coil are in series with the external circuits; opposed to shunt winding.
... gives a weak field. The armature coils cut this and pass a current through the circuit. The magnets are further excited, and the field becomes stronger; and so on till the dynamo is developing full power. Series winding is used where the current in the external circuit is required ... — How it Works • Archibald Williams
