A commutator is used to interconnect the rotor winding to the outside world (it doesn't connect to the armature/stator winding). It's similar to slip rings, although much more complex. It switches current direction as the rotor spins so a constant DC is applied to the rotor field winding.
AnswerA commutator....
(a) enables a rotating machine to be electrically connected to an external load.
(b) is a rotary switch, which acts to rectify the a.c. voltage which is naturally generated in any rotating machine, to provide a d.c. voltage output.

Is a commutator the rotating element of a motor?
The commutator is part of the armature on a DC motor and this assembly is the rotating element of a motor.
What happens if commutator of DC generator is removed?
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!
What part of a DC motor on the armature is responsible for connecting brushes to a coil?
commutator
What does the commutator in an electrical motor do?
If there is a commutator, it means you are dealing with a DC motor.The commutator acts like a switch to supply voltage to a revolving armature from the stationary brush assembly.A commutator has commutator bars, each seperated by mica insulation. Each coil of the rotating armature is connected to two bars that are in directly opposite positions across each diameter of the armature.The total number of commutator bars depends on the design of the windings on the armature: either "lap" or "wave" windings can be used on a DC motor or generator which is provided with a commutator.For more information see the answer to the Related question and also the Related link shown below.
What is the need of commutator in DC generator?
The commutator has two functions: (1) it enables current to pass to the external fixed wiring from the rotating armature, and (2) it is a rotating rectifier, which converts the a.c. voltage generated in the rotating armature, to a d.c. voltage.
What is meant by shaft and commutator in the armature?
The armature is the moving part of a motor or generator. Tthe shaft is the central rod on which the armature rotates. The commutator is the part that transfers the power too or from the moving windings in the armature to the static part of the motor or generator (either too or from the electricity supply).

Basic principle of commutator motor meter?
It is based dynamometer principle with ironless motor with a wound armature having a commutator. The two coils are connected in series with supply and armature coil is connected in parallel to it.
