A generator is a electro-mechanical device which converts kinetic energy into electrical energy. The basic concept is when a wire passes through a magnetic field, it causes the electrons to flow perpendicular to the field. Remember the right hand rule? If your fingers are in the direction of the field, your thumb is the direction of electrical current. Depending on the type of motor, the rotor (shaft) and stator (houses the rotor) will contain the wires or magnets. A motor is no different then a generator as it provides the kinetic energy by applying electrical energy.
construction of DC generator
Alternator and ac generator is equal
Exciter controls the magnetic field in the generator system and controls the output voltage and/or current.
Starting of the synchronous motor using the DC generator creates a magnetic field.
it is to help with the heat in are house
Induce current in the generator windings.
The generator pull cord is used to start the generator by manually turning the engine. When the cord is pulled, it rotates the engine's crankshaft, which initiates the combustion process and starts the generator. The purpose of the pull cord is to provide a simple and reliable method for starting the generator when there is no electric starter available.

Generator work on the principle of conversion of mechanical energy into electrical energy.EMF - Electro-Motive Force. When a conductor passes through a magnetic field, electrons are forced to move along the conductor thereby creating 'power' (as a simple explanation).
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator
No, simple machine. It uses the spinning shaft to revolve a gear which powers a generator. Very simple.
