In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
You have a seperately excited generator and then you have a shunt generator which has the field winding in parallel with the armature terminals. In DC machines a separately excited generator could be run as a shunt generator provided the field winding is designed to work on the generated voltage. A separately excited alternator needs a DC supply for the field winding. In car alternators that is taken from the main winding via a rectifier and a voltage regulator.
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.
its creates the magnetic field trough the electricity,which we called exciter for it.we send some electric shocks to the field coils,then it will magnetized the stater of the generator. When Diesel or petrol engine rotates the rotter of the generator, EXCITED stater act as a magnet. Depend on alternator`s design,rotter or stater one always EXITED to be a magnet. When engine turns the Alternator against the magnetic field,electricity is produced.
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
Excitation is the phenomenon by which you control the excitation of field winding of a generator. In DC generator field winding is placed on stator and this field winding can be self excited or seperately excited depending upon the type on generator used. AC generators can also be self excited or seperately excited type but field winding is placed on rotor nad armature winding on stator.
More due to the impedance levels in the generator
A shunt generator is a method of generating electricity in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.A direct current (DC) generator, not using a permanent magnet, requires a DC field current. The field may be separately excited by a source of DC, or may be connected to the armature of the generator so that the generator also provides the energy required for the field current.
The field winding on a generator is the winding that is electrified to create an electromagnet; it is generally the winding found on the rotor (the rotating part of the generator).
while the engine is running , put your + lead from your voltmeter on the armature lug( the big lead). take off your field wire from the generator (don't add power to the lead from the regulator or you will fry the regulator) add a power source to the field lug of the generator. the generator should start climbing, if you get 14.5 volts , the generator is good
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
The starter is usually the person who shoot the gun or is the person recording time in Track and Field
A generator generates electricity. A simple generator consists of a magnetic field, relative motion between the conductor and magnetic field, and a conductor to carry electrical current to the load. Turbines drive the generators to create the necessary relative motion utilizing steam or water as the prime mover.
the voltage which is given for creating magnetic field in a generator is known as excitation voltage.
My only guess is that ,,, because electromagnets are more stronger and powerful than the ordinary magnets. Moreover they provide continuous magnetic field required for the generator. the generator in your car will have an electromagnet in the field the field will set the charge rate new cars have an alternator the field is the electromagnet in the rotor older cars have a true generator where the field is in the stator
