Re: What Is An Exciter and How Does It Work? Answer Ramesh Gaur

An exciter is a device that supplies excitation voltage to the fixed poles of a generator. There are two main types of exciters: 1) a static exciter, and 2) a rotary exciter. A rotary exciter is a small additional generator mounted on the main generator's shaft. It supplies DC voltage to the rotary poles via slip rings and brushes in a DC generator. In an AC generator, the output of the AC exciter is rectified by rotating diodes and supplies DC to the main generator's fixed poles. The exciter builds up initial voltage through residual magnetism.

Re: What is an exciter and how does it work?

Answer There are two types of exciters, static


# 1 exciter and rotory
exciter.purpose of excitor is to supply
the excitation dc
voltage to the fixed poles of
generator.Rotory excitor is
an additional small generator mounted
on the shaft of main
generator. if it is dc generator, it
will supply dc to the
rotory poles through slip ring and
brushes( conventional
alternator). if it is an ac excitor,
out put of ac excitor
is rectified by rotating diodes and
supply dc to main fixed
poles.ac excitor is the ac generator
whose field winding
are stationary and armature rotates.
intial volatge is buit
up by rsidual magnetisim.

Re: What is an exciter and how does it work?


Answer Exciter is a device or cobination of
# 2 devices whcih supplies
the megnatising current to generate the
working flux.
In industrial applications basically 3
typpes of exciters
are used in alternator1)Static exciter
2)Permanant mannet/Brushless exciter
3)DC/Pilot exciter
