Question
what is the function of a commutator in a dc generator?
 Question Submitted By :: Guest
I also faced this Question!!     Rank Answer Posted By  
 
  Re: what is the function of a commutator in a dc generator?
Answer
# 1
it rectifies the output alternating current so as to produce
unidirectional alternating current i.e pulsating DC.it
reverse the negative polarity current to a positive one so
as the output is a pulsating DC

Answer
# 2
Generally all types of generators induced emf in sinusoidal
wave form (A.C). In particularly D.C generator commutator
function is convert A.C emf into D.C.

Answer
# 6
in generator only alternating current is produced so to
making it unidirectional we use commutators it acts like a
rectifier to convert ac to pulsating dc
 
Is This Answer Correct ?    11 Yes 2 No

# 7
It converts alternating current to unidirectional current
and also provied point for collection of current.

I DONT THINK ITS RECTIFIENG. ITS JUST A CONDUCTOR BUTWEEN
COILS AND BRUSHES.

  Re: what is the function of a commutator in a dc generator?
Answer
# 10
the function of commutator is to lead current from external stationary leads to the rotating coils of the armature winding in case of motor and to draw current from armature winding to external circuit in case of generator
basically it act as a rectifier as it converts sinusodial(a.c.) signal into d.c signal
