it serves as a mechanical rectifier
If the commutator is removed from your generator, you (if you connect slip rings) get AC supply instead of DC supply. the function of the commutator is to convert AC to DC supply and vice versa.Additional AnswerRemoving the commutator will also prevent you from connecting the output of the generator to its load. Remember, the generator's armature is spinning!
All types of generators induce EMF in sinusoidal wave form. (A.C.) In a D.C. generator the function of a commutator is to convert A.C. EMF into D.C. The commutator rectifies the output that is the alternating current so as to produce unidirectional alternating current (pulsating DC). This reverses the negative polarity current to a positive one so as the output is a pulsating DC.
The commutator is used to convert the AC to DC
The commutator is used to convert the AC to DC
To send electrical voltage to the starter when engaged.
the purpose of carbon burshes is to ensure electrical connection between the rotating commutator and stationary load circuit.the burshes are made of carbon and rest on the commutator carbon burshes are employed to reduce sparking and provide better commutation.

function of dol stater
the starter is bad and has an internal short That answer is simplistic. On my '98, for months I could hit the starter and make it work. When I actually removed and disassembled the starter, one of the brushes was worn out. Hitting the starter moved it just enough to contact the commutator. Installed new brushes three years ago and haven't had any problems since.
what is necessity of commutator in DC generator
Its not worth replacing the starter motor brushes on any car. By the time the brushes are worn, there is probably other wear and tear to the bearings, the commutator, and the windings. Better to just replace the starter. Same deal with the brushes in an alternator.
