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.
To limit the fault current used surge protective resistance in generator rotor winding to protect the rotor winding heavy damage.
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
damper winding help to maintain the magnitude phase shift (on load chages) between rotor an stator flux and kill some parasite currents produced by the leakage flux moving out the rotor winding to the rotor core.
Winding: To wind the coils into the slots on the stator or rotor and connecting them up to form a winding. Re-winding. Is to remove the old winding and doing what I explained above.
a rotor which is powered with a dc voltage using a commutator turns within a stator winding system, and the created magnetic field cuts through the stator windings and induces a voltage into the electrical winding circuits.

It is a more convenient arrangement because it does not need a commutator. The rotor is fed with DC through slip-rings and the brushes last much longer. The main current is generated in the static winding enclosing the rotor.

To limit the fault current used surge protective resistance in generator rotor winding to protect the rotor winding heavy damage.
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
A commutator applies power to the best location on the rotor, and in a generator, picks off power similarly.
By connecting a commutator to the rotor of the generator.
AC motor has two main winding components - stator and a rotor. Stator winding is stationary where as rotor winding is on rotating part.
The field winding in the stator is exposed to the full current generated by the rotor's winding.
damper winding help to maintain the magnitude phase shift (on load chages) between rotor an stator flux and kill some parasite currents produced by the leakage flux moving out the rotor winding to the rotor core.
The field winding on a generator is the winding that is electrified to create an electromagnet; it is generally the winding found on the rotor (the rotating part of the generator).
