Answer / sunil guru
COMMUTATORS IS USED ALONGWITH THE BRUSH TO PROVIDE UNI-
DIRECTIONAL CURRENT AND TORQUE FROM THE ARMATURE
AND IT CONVERS AC TO DC IN DC MOTOR OR GENERATOR

Answer / kalaimagal
In dc motor actually dc supply will be given as source for
excitation.the function of commutator is to convert the ac
supply to dc supply,it same as rectifier function.

Answer / bhagya
sir actually the function of the motor is to convert
electrical to mechnical energy but wat is the purpose of
commutator in dc motor.if we ll not give ac supply
Is This Answer Correct ? | 1 Yes | 1 No |
Answer / anbuselvan.g
Motor is always convert Electrical power into Mechanical Power.
Here in DC motor, we just give AC supply as Electrical
Power, the Commutator will convert or rectify the AC into DC
to its windings.
It is also called as Rotating Rectifier.
The same function happen in DC generator which convert
Induced AC power in Armature into DC power to their loads.
