The fact a generator is A/C is a function of how the generator works.
Think of voltage as water pressure.
A generator works by sweeping a magnet around the inside of a coil of wiring. This means that the electrons are being moved first one direction, then the other.
the result is A/C power.
D/C sources generate a constant stream of electrons from one side to the other, like a battery.
It's possible to convert AC to DC by blocking flow of the electrons in one direction, but AC power has a lot of advantages for power grid use: it can be put through a transformer, making high-voltage transmission over lines more efficient, and it is better for running motors, which is the largest use of electrical power in terms of the amount of raw power consumption.
The short answer: because the physics of a generator makes it impossible.

How can an ac generator be converted to DC generator?
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
Does DC generator produce a smooth DC voltage output?
A DC generator typically produces a pulsating output voltage rather than a perfectly smooth DC voltage. This is due to the nature of its operation, where the generated voltage fluctuates with the rotation of the armature within the magnetic field. To achieve a smoother DC output, additional components such as filters or voltage regulators are often used to reduce the ripple and stabilize the voltage.
What would happen if a shunt-excited DC generator was operated at too low a speed?
A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.
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 is the theory of conversion of AC to DC using 3-phase induction motor and DC shunt generator?
The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.
What do you mean by DC generator?
DC generator is used to produce direct current. The basic DC generator have four basic parts 1. A magnetic field 2. A single conductor or loop 3. A commutator 4. Brushes

What is DC generator?
because DC generator generates generally generate DC power but as it has slip rings which convert it into ac output power
What type of voltage is the output at the bat terminal of the ac generator?
dc
How the output characteristics of AC and DC generator vary from other?
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
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.
Theory for load test on dc shunt generator?
load test on dc shunt generator is a test to plot the internal and external characteristics of the generator.

Can you test the output amps of a DC generator with no load?
Any voltage source, whether a generator or a battery, will NOT supply an output current unless it is connected to a load. So the only way to test the output current is by connecting it to a load.
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.

Does a generator produce DC electrical current?
Yes, provided its a stationary field type generator and it has split rings on its armature. take a general dc motor used in tape recorders and observe it. it you give supply, its a dc motor if you rotate it by the help of other and take the output from its leads its a dc generator thats simple
