Commutators are used to get unidirectional current Flow through the external circuits in DC generator system.A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator.

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!

By connecting a commutator to the rotor of the generator.


How can you generate a DC?

U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.


Does a generator produce ac or DC voltage?

NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.


What is commutation in DC machines?

It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.

What is the purpose of a commutator in a electric motor?

A commutator applies power to the best location on the rotor, and in a generator, picks off power similarly.


How commutator converts AC to DC?

There is no conversion of AC to DC a commutator is the key to creating straight DC voltage. "The commutator rotates with the loop of wire just as the slip rings do with the rotor of an AC generator. Each half of the commutator ring is called a commutator segment and is insulated from the other half. Each end of the rotating loop of wire is connected to a commutator segment. Two carbon brushes connected to the outside circuit rest against the rotating commutator. One brush conducts the current out of the generator, and the other brush feeds it in. The commutator is designed so that, no matter how the current in the loop alternates, the commutator segment containing the outward-going current is always against the "out" brush at the proper time. The armature in a large DC generator has many coils of wire and commutator segments. Because of the commutator, engineers have found it necessary to have the armature serve as the rotor(the rotating part of an apparatus) and the field structure as the stator (a stationary portion enclosing rotating parts). Which is the inverse of an AC Generator."


What is the function of a commutator in DC generator?

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.


How is a DC waveform produced from the output terminals of a DC generator?

A DC waveform is produced from the output terminals of a DC generator through the action of a commutator, which converts the alternating current induced in the armature windings into direct current by reversing the direction of current flow at the appropriate times. As the armature rotates within the magnetic field, the commutator ensures that the output current remains unidirectional, resulting in a DC waveform at the generator terminals.
