Direct Current Generator 

Historically, direct current machines came into being before alternating 

current machines because the scientists of that time (about the middle of the 
19th century) were only familiar with battery sources and consequently 
made motors which operated from batteries, as well as generators to charge 
the batteries. 1) ____________, and will not in the foreseeable future, since 
the DC motor offers a controllability not yet approached by AC motors. 
Nevertheless a thorough study of DC generators is necessary 
2) ____________. 

3) ___________. Mechanical power input received from a prime mover 

(DC motor in this case) is converted electromagnetically into electrical 
energy. This electrical energy can be changed into heat as is done by 
connecting load resistors across its armature terminals. The field winding of 
the generator is excited with direct current. It is based on the principle of 
production of dynamically or motionally induced emf (Electromotive 
Force). 4) __________, dynamically induced emf is produced in it 
according to Faraday's Laws of Electromagnetic Induction. This emf causes 
a current to flow if the conductor circuit is closed.  

The field of the machine produces the magnetic flux. It is basically a 

stationary electromagnet composed of a set of salient poles bolted to the 
inside of a circular frame. Field coils, mounted on the poles, carry the  
D.C. exciting current. The frame is usually made of solid cast steel, 
5) ________. In some generators the flux is created by permanent magnets. 
The armature is the rotating part of a DC generator. 6) ________. The core 
is composed of iron laminations that are forming a solid cylindrical core. 
The laminations are individually coated with an insulating film so that they 
do not come in electrical contact with each other. 7) _______. 

1.5. Fill the gaps in the text “Direct Current Generator” with 

phrases given below. There are 3 odd sentences! 

a) It consists of a commutator, an iron core, and a set of coils; 
b) They support the field coil; 
c) Whenever a conductor cuts magnetic flux; 
d) A D.C. generator is an energy converter; 
e) it is made of cast steel; 
f) As a result, eddy-current losses are reduced; 
g) Although superior in many ways, AC machines have not completely 
replaced DC machines; 

h) Current flows and the poles are electromagnetised and produce the 

necessary flux; 
i) because the construction of motors and generators is the same; 
j) whereas the pose pieces are composed of stacked iron laminations. 

1.6. Match the essential parts of DC generator with their 

descriptions or functions.  

Describe the functions using the combination “the function of … is …” 
 
1. Magnetic frame  
a) It provides a path of very low reluctance to the 
flux through the armature from one pole to another 
one. 

2. Pole cores and pole shoes
b) They are used to reduce losses of friction and 
other mechanical losses.

3. Pole coil or field coils
c) This part rotates inside of an armature.

4. Armature core 
 
d) It is a very useful part of DC generator. Its main 
work is to take input AC and give output DC. 

5. Armature winding
 
e) They spread out the flux in the air gap and also 
reduce the reluctance in magnetic path.

6. Commutator 
 
f) It provides mechanical support for the poles as 
well as mechanical strength for generator machine.  
It also carries the magnetic flux produced by poles.  

7. Brushes  
g) It takes supply from commutator and gives output 
to terminal of generator.

8. Bearings 
h) It is a static part of a generator. 

9. Stator 
i) It carries current and generates electromotive 
force.

10. Shaft

the necessary flux.
