Chapter 43, Problem 1SQ
a.
To determine
Draw the diagram of series motor.
a.
Expert Solution
Explanation of Solution
DC motor:
A DC motor is an electrical rotary machine that is used to convert electrical power into
Series motor:
In the series motor, the field winding and armature winding are connected in series. Since the field and armature winding are in series, it should be large enough to carry the current of the armature circuit. The diagram of series motor is shown in Figure 1. The series field winding is represented as
Conclusion:
Thus, the diagram of series motor is drawn.
b.
To determine
Draw the diagram of shunt motor.
b.
Expert Solution
Explanation of Solution
Shunt motor:
In the shunt motor, the field and armature winding are in parallel connection. The rheostat is connected in series with field winding to vary the resistance of field circuit. The diagram of shunt motor is shown in Figure 2. The shunt connected field winding is represented as
