What are the functions of different parts of DC generator?
Parts of a DC Generator
1. Stator : The main function of the stator is to provide magnetic fields where the coil spins. A stator includes two magnets with opposite polarity facing each other. These magnets are located to fit in the region of the rotor. 2. Rotor : A rotor in a DC machine includes slotted iron laminations with slots that are stacked to shape a cylindrical armature core. The function of the lamination is to decrease the loss caused due to eddy current. 3. Armature Windings : Armature windings are in a closed circuit form and are connected in series to parallel for enhancing the sum of produced current. 4. Yoke : The external structure of the DC generator is known as Yoke. It is made of either cast iron or steel. It provides necessary mechanical power for carrying the magnetic-flux given through the poles. 5. Poles : The function of a pole is to hold the field windings. These windings are wound on poles and are either connected in series or parallel by the armature windings. 6. Pole Shoe : Pole shoe is mainly utilised for spreading the magnetic flux to avoid the field coil from falling. 7. Commutator : A commutator works like a rectifier that changes AC voltage to DC voltage within the armature winding. It is designed with a copper segment, and each copper segment is protected from each other with the help of mica sheets. It is located on the shaft of the machine. 8. Brushes : The electrical connections can be ensured between the commutator as well as the exterior load circuit with the help of brushes
