Exciter Voltage effect

Exciter Voltage effect

Exciter Voltage effect

(OP)
Sirs/Maams,
I am a mechanical engineer and I work for a pump manufacturer in Ashland, Ohio.
I am trying to find information about the effect that exciter voltage has on the output of a motor/generator set.
See, we have a 50 hp 50 Hz MG set and there are very few controls on the panel. There is a knob labeled "Output Voltage" which seems self explanatory, and one labeled "Exciter Voltage" which is less clear to me.
I understand the basic theory of operation of synchronous generators, but what effect will the exciter voltage have if it is misadjusted and how will I know if it is adjusted properly? Do I need an O-scope on the output to monitor the waveform or something?
This equipment is seldom used, but it is in good condition and was reported to operate well several years ago when it was used last. Unfortunately, the guy who knew how to run the gear is no longer with the company.
Anyhow, if you can give me some direction or point me to a good resource, I'd really appreciate it.
Thanks,
Chris Webber

etc. as a good start
Essentially, the exciter produces electrical energy to produce the electromagnetic field that is usually created in the rotor winding. The stator winding emf or voltage or power is dependent on the rotor field winding electromagnetic strength.
It may be a good idea to contact the exciter manufacturer for more information.
