Question
What is the working of Field winding in dc motor, in which
part is it work or why ?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
field winding is placed on the stator of the motor this
winding having more no of turns which generates magnetic
flux .
 
Is This Answer Correct ?    11 Yes 2 No
Venu
 
Answer
# 2
The motor needs the current and magnetic flux to create
motion
The mgnetic field is crated by field winding where as
armature carries the current resulting into the rotation of
armaure
 
Is This Answer Correct ?    4 Yes 4 No
