Explain the Construction of dc machine

The constructional features of a dc machine are given below. A dc machine has two major parts, magnetic ?eld system and armature. The ?eld system is the stationary part of the machine and is called stator. The armature is the rotating part and is known as rotor. A direct current machine has the following parts which are shown in ?gure.

1. Yoke or Magnetic frame.

2. Field system- Pole cores, pole shoes and ?eld coils

3. Armature- Armature core and armature winding

4. Commutator, brushes, bearings, etc.
