Can you use a dc series motor as a prime mover for a dc generator. if not why?

A DC series motor would be ill-suited to this application.
There would be times when the generator would be only lightly loaded and would present only a small mechanical load to the motor. Under these conditions the current in the field winding of the motor would become smaller and it would turn faster to generate the counter EMF necessary to balance its supply voltage. This could result in damage to both the motor and the generator.

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 is prime mover in a dc generator?
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 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
How control the reverspower for diesel generator?
I guess you're thinking that reverse power is a generation error, but it is a change in flow direction. When two generator are running in parallel nd of sudden a generator2 prime is dropped nd due to circuit breaker2 is still in on state Gen2 draws power from Gen1 and acts as a motor. this action will damage the prime mover(engine) nd AVR too. Of course upto 10 amp of reverse current is allowed into a generator as of considering as back emf (while running as generator). So in order to stop thing reverse power, a relay is used which senses the directional flow of power nd immediately turns off the circuit breaker of off prime mover unmatched droop also develops this reverse power flow because of change in voltage nd load sharing
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.
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

What happen if a prime mover fails when two generators are in parallel?
It acts as synchronous motor by consuming power from the other generator....
Is electric motor a prime mover?
no it is not
What Turns the arm of a generator?
It is called the 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 generator run?
By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).
How can you use a synchronous motor as a synchronous genarator?
to use prime mover
Why is necessary to control over speed in a motor?
over speed control is recommended for all prime mover driven generator to prevent over frequency operation of load connected to a system supplied by the generator and also to prevent possible over frequency operation of the generator itself from Ac system.
How do generators run?
By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).
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
