Construction of a DC generator:
A DC generator consists of the following essential parts.
1. Magnetic frame or Yoke.
2. Pole-Core and Pole-Shoes.
3. Pole Coils or field Coils.
4. Armature Core.
5. Armature Windings or Conductors.
6. Commutator.
7. Brushes and Bearings.
YOKE:
The outer frame or yoke serves double purpose.
1. It provides mechanical support for the poles and acts as a protecting cover for the whole machine.
2. It carries the magnetic flux produced by the poles.
POLE CORES AND POLE SHOES:
The field magnets consist of pole core and pole shoes.
1. The spread out the flux in the air gap.
2. They support the exciting coils.
POLE COILS:
When current is passed through these coils, they electromagnetise the poles which produce the necessary flux that is cut by revolving armature conducts.
ARMATURE CORE
It houses the armature conductors or coils and causes them to rotate and hence cut the magnetic flux of the field magnets.
ARMATURE WINDING:
The armature windings are usually former-wound. It cuts the flux
he brushes whose function is to collect current from commutator.
