through commutator.

Answer / rajesh sharma

commutator cut dc power in rotor so that rotating magnatic
feild become in rotor and this magantic feild atract stator
magnatic feild due that motor run. dc power cut with
insulated segments.

Answer / lebogang

The commutator convert dc signal to ac signal and vice versa

Answer / ranjan

to convert dc to ac

Answer / saravana babu

in dc motor,rotor provides an alternating flux for the

from dc supply to rotor... so commutator need for dc motor..

Answer / vinothbabu.k

commutator brush is made of carbon material.and it holds in
the rotor segment, its mainly used to collect current from

Answer / muhammad aamir

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 / vidhya

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.
