Need for a solution discussion Point 1 and 2 and 3 please
Exp. 1 The construction of a d.c Machine
Objective:
The object of this experiment is to study details of a d.c machine in general.
Theory:
A d. c Machine has a stationary member rotating member called f rotor'. The stator
consists of:
1.
Ayoke or cylindrical frame.
2.
The field windings.
3.
The field Poles.
4.
The interpole and its winding.
5.
Brushes.
The rotor consists of:
1.
Armature shaft.
2.
Armature core.
3.
The armature winding.
4.
The commutator which converts the alter individual armature conductors to
a d. c voltage across the brushes.
Procedure:
Inspect the dis assembled machine carefully and record all necessary
information listed below;
Run (1): General Data.
