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."
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.
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
There is not the big different between AC and DC generator and the common part of both of them areRotorStaterFrameMagnetic FieldBarringShaftWinding (Lap or Wave)Cable boxThe big different between both of them is the commutator and split rings which we use to convert DC to AC.
A DC generator has a commutator, a rotary switching system, that connects a different winding of the rotor, for each fraction of a turn. Thus keeping the polarity one way only. The stator windings are fed a proportion of the DC generated, to make an electromagnet. The power is taken off from the rotor via the commutator switching system. An AC generator supplies the rotor with a DC current, via slip rings on the shaft, to exite it. (Makes the rotor an electromagnet) The power is taken off from the stator windings and alternates from one polarity to the other, as the rotor turns inside, producing AC and not having to go through a switching ystem.
megger are available in ac &dc
its commutator..which converts ac produced by and motor to pulsating dc ... more the commutator divide more accurate dc..means less pulse in dc
The commutator is used to convert the AC to DC
The commutator is used to convert the AC to DC
Because, the commutator segments are used for converting AC to DC.
Yes
A "Rectifier" converts AC current to pulsating DC current.
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!
A Rectifier converts Alternating current into Direct current
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
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.
By using rectification we can convert the AC into DC....
no unless some commutator like device is used
