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.
Is the output from a dc generator not pure dc?
The output from a DC generator is not pure DC due to the presence of ripple voltage, which results from the mechanical commutation process. As the generator's rotor rotates, the commutator segments switch connections, leading to fluctuations in voltage. While the output is predominantly direct current, these variations can cause it to deviate from a perfectly smooth DC signal. Additional filtering may be required for applications needing a more stable output.
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 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.
