Answer / tarun aggarwal ymca

An electric generator or electric motor that uses field coils rather than permanent magnets will require a current flow to be present in the field coils for the device to be able to work. If the field coils are not powered, the rotor in a generator can spin without producing any usable electrical energy, while the rotor of a motor may not spin at all.this current is provided by the exciter

exciter as per its name provides exitation to the
generator. it gives the starting torque to the generator
which helps in pre acceleration of the generator.
