what is the function of a commutator in a dc generator?
Answer Posted / vindhya vasini
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
