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.

∙ 14y agoIt's part of a larger generator that uses field windings (typically on the rotor or spinning part of the generator) instead of permanent magnets to create an electromagnet. The exciter generator provides the power to the field windings. It often is attached to the same shaft as the larger generator.

∙ 13y agoAn exciter is a piece of apparatus which is used to charge a rotor within a generating alternator, with a DC voltage ; often 660 volts.
this creates a magnetic filed effect around the rotor and since this is spinning at high speed, this induces a high frequency voltage signal into the surrounding stator windings .

How does a generator exciter work?
Exciter controls the magnetic field in the generator system and controls the output voltage and/or current.
Where can a DC exciter be found?
It can be found on an electrical generator set. It is used to supply the DC voltage for the field coils.
Why the pilot exciter having high frequency in electrical generator?
I'm no expert but I believe the high frequency is due to the number of poles (North-South) of the pilot exciter. The frequency of a generator is directly link to its speed and the number of poles. Most generators will run at 1800RPM and will have 4 poles to achieve 60Hz. The pilot exciter being on the same shaft will also run at 1800 rpm but will probably have more then two poles. finding the formula for frequency of a generator should help you in answering your question. The next question should be why would you build a pilot exciter with multiple poles and a high frequency? The output of the pilot exciter is going to be rectified to DC so it would make sense to do it with a high frequency and get a smoother DC signal out of the rectifier.
What is ceiling voltage in exciter?
ceiling voltage is the maximum field voltage that the exciter can withstand before going into unstability
What are the disadvantages of a brushless generator?
A brushless generator, in contrast, typically uses a solid-state rectifier assembly in place of the brushes and rings. This assembly contains no moving parts. This is important, as it makes the system more reliable and less prone to mechanical breakdown, jamming or seizing as a result of obstructions in the casing. Instead, a continuing charge is built up by transferring a portion of the generator's AC charge back into the exciter.
How does a generator exciter work?
Exciter controls the magnetic field in the generator system and controls the output voltage and/or current.
What is the function of exciter rotor and stator in Generator Operation?
In the operation of a standard generator, the exciter rotor and stator provide DC-type energy to an AC-type supply. This allows the exciter to maintain a constant DC source.
What is a exciter used for and why?
exciter is a component in a electrical generator and or the low power rf stages of a radio transmitter
How generator exciter works?
Generator Exciter is a new way for people to generate serial keys for pirated software for various companies. This is well known as something called a "keygen".
What is the excitation of the generator?
The rotor must have a magnetic field in order to generator voltage in stator winding. The exciter circuit generates this DC filed in the rotor.
Where can a DC exciter be found?
It can be found on an electrical generator set. It is used to supply the DC voltage for the field coils.

What is the exciter voltage needs to test the generator?
Because the voltage is fixed (within allowable limits) whereas the current varies according to load.
What different rotary exciter and static exciter?
Static exciter mounts as part of the motor control package, separate from the motor. Rotor exciter mounts on the rotor of the motor.
When was Exciter - band - created?
Exciter - band - was created in 1978.
When was Exciter - album - created?
Exciter - album - was created in 2000-06.
How do you connect and test exciter voltage?
To start the ac motor at starting by exciter.
