DC machines are essential in various industrial applications, and understanding their constructional features and working principles is crucial.Separately Excited DC Motor Circuit:
o Field winding connected to separate
DC source
- Armature connected to DC source through controller
2.Self-Excited DC Motor Circuit:
o Series-Wound: Field winding in seriesTypes:
- Series-Wound (e.g., universal motors)
- Shunt-Wound (e.g., dynamos)
* Compound-Wound (combination of series and shunt)
