 Question Submitted By :: Rabi
I also faced this Question!!     Rank Answer Posted By  
 
  Re: what is the function of commutator in dc motor?
Answer
# 1
in dc motor commutator converted DC to AC

in DC genator its function is AC to DC that's way we called
as commutator is a mechanical rectifier

Answer
# 2
The DC Generator generate the AC supply only in Armature
not DC Supply.But we want Dc source , so want one converter
thats why we use commutator.In shortly we can say its
converts AC source to DC source.

Answer
# 5
its obvious t rectifies ac to dc..bcoz the current produced
by the dc generator will b of sinusoidal form obviously ac
since it s a dc generator it should produce only dc
current..in order 2 convert it to dc v r using this
commutator.

Answer
# 6
it the part of dc generator.in dc generator two half rings
are used the purpose of these rings is to prevent the
direction of current as in ac thee are caled as commotator

Answer
# 8
Dear all please note commutator is not a converter, all are
telling dc ot ac, we already giving dc supply to motor
through motor terminals at A1 & A2 (ie.+ & -) it is
transformed to rotor winding or bars through Brush and
commutator.

DC supply - Motor TB A1&A2 - Carbon Brush - Commutator -
Rotor winding or copper bars

  Re: what is the function of commutator in dc motor?
Answer
# 9
commutator brush is made of carbon material.and it holds in
the rotor segment, its mainly used to collect current from
the winding..

  Re: what is the function of commutator in dc motor?
Answer
# 10
in dc motor,rotor provides an alternating flux for the
reason of provides rotating torque so that need for ac
supply to rotor..in order to that comutator converts the ac
from dc supply to rotor... so commutator need for dc motor..
