The prime mover in a DC generator is the mechanical device or system that provides the initial energy required to rotate the generator's armature. It could be an engine, turbine, or any other source that converts mechanical energy into rotational motion. The prime mover rotates the generator's rotor, inducing a magnetic field and generating electrical power.

What happens if an ac supply is given to dc generator?
AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
Prime movers for power generating operation?
A "prime mover" is part of a generator - specificially the thing that's causing the generator to spin (such as a turbine). It is called the prime mover because it is what is causing the generator's rotation.
What has to be interchange in order to reverse the direction of rotation of shunt generator?
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
What factors affect the rotation in a DC generators?
Your question is unclear. Do you mean how the rotor of a d.c. generator is driven? If so, then its shaft is connected to a 'prime mover' which can be an internal combustion engine (petrol or diesel engine) or a turbine (steam, water, gas). The type of prime mover usually depends on the source of fuel available to operate that prime mover and whether it is fixed or portable.
What is the probable cause for no voltage generated in a DC compound generator?
In any DC generator the causes to fail to produce voltage is loss of residual flux in the field or fields , poor brush contact in the commutator(clean the brushes and commutator) , check all the terminals of the generator and voltmeter may not be functioningand lastly check the coupling and the prime mover is rotating.
How generator run?
By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).
What happens if an ac supply is given to dc generator?
AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
What fuel used in DC generator?
Any generator, d.c. or a.c., is driven by a 'prime mover'. It's the prime move that uses fuel, not the generator! There are lots of different types of prime mover, including combustion engines (petrol, diesel), turbines (gas, water, air), etc.
How do generators run?
By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).
Is it possible to use a dc motor as a prime mover for a three phase syncronous ac generator?
It is possible to use it

Why is reverse power protection required in units like signal generators?
Results of Motorization of a GeneratorIf a generator loses prime mover power, it acts as a motor with a DC field on the rotorThe DC field will cause the rotor to try and follow the AC field in the same direction as beforeIf the mechanical drag on the rotor is heavy, it will fall behind and "slip poles,"inducing a large voltage into the rotor; this can cause insulation breakdown of the windings, flashover at the brushes, and violent shaking of the generator mountings.If a generator loses DC excitation to the rotor it will not generate, but the prime mover power will still turn the rotorNow the generator acts as a motor running at no load

Why a dc shunt generator may fail to self excite?
If there is no residual magnetism in the field poles then there would be no flux too induce the initial voltage for self exitation
