The term simplex and duplex windings are linked to DC machines the rotor/armature winding in DC machines are classified into two types based on the plex of windings.
Differences between Simplex and Duplex Windings
| Feature | Simplex Windings | Duplex Windings |
|---|---|---|
| Rotor Construction | It comprises of a single, complete, closed winding wound on a rotor | It comprises of a single, complete, closed winding wound on a rotor |
| Number of parallel paths | It comprises a rotor with two complete and independent sets of rotor windings | The number of parallel paths is equal to the number of poles |
