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.
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 ceiling voltage in exciter?
ceiling voltage is the maximum field voltage that the exciter can withstand before going into unstability
What is brushless excitation system?
3 phase synchronous generator or motor require DC current in the rotor. Conventional way of supplying DC requires use of commutators, which requires timely maintenance. To overcome this Brush less Excitation systems is used. Brushless Escitation system consists of one pilot excitor - DC generator with rotating PM as the field and the armature as the stator. The armature of the pilot excitor is connected to the stator of main excitor which is a 3-phase synchronous generator (please do not get confused, this is not our alternator but the exciter for the alternator). The rotor of the main exciter is connected to a diode bridge to get DC. This is connected to the rotor of our alternator.
What is a exciter generator?
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.
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 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.
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.
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.
When was Impact Exciter created?
Impact Exciter was created on 2010-07-07.
Specs for a 570 Yamaha exciter?
The Yamaha Exciter 570 has a top speed of 105 miles per hour. The Exciter I had 77.2 horsepower and ran at 7200 RPMs.
How wartsila abb amg 1600 produce electrical energyand the generator operate?
the prime mover rotates the rotor of the alternator. the exciter contains stator coils with remanence induces voltage in the rotating windings of the exciter rotor which is then rectified and goes through the main field winding. the rotating rotor flux cuts through the stator windings inducing voltage on them. the AVR controls the field current to the exciter stator coils. DC current for pole formation.
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
What is ceiling voltage in exciter?
ceiling voltage is the maximum field voltage that the exciter can withstand before going into unstability
