Types of dc motor

Types of dc motor

     D.c motors are classified depending upon the way of connecting the field winding with the armature winding. The different types of d.c motors are

              

1. Shunt motor

2.Series motor

3. compound motors

The compound motors are further classified as 

        

1. Short shunt compound motors

2. Long shunt compound motors 

compound generator

compound generator 

     In this type, the part of the field winding is connected in parallel with armature and part in series with the armature. Both series and shunt field winding are mounted on the same poles. Depending upon the connection of shunt and series field winding compound generator is further classified as .

       

     1. Long shunt compound generator 

     2. Short shunt compound generator 

1. Long shunt compound generator

     In this type, shunt field winding is connected across the series combination of armature and series field winding as shown in the picture.

2. Short shunt compound generator 

     In this type, shunt field winding is connected, only across the armature excluding series field winding as shown in the below picture
