WebThe voltage of a separately-excited DC generator can be controlled by controlling generator speed, by using a variable field supply, or by a combination of both. A self-excited dc generator can be controlled by generator speed or by a rheostat or electronic circuit that reduces the field current. A combination could also be used. WebFor shunt or series excited generators, the field winding is disconnected from the machine and connected across an external supply. Now, from the emf equation of dc generator, we know that Eg = kɸ. Hence, the generated emf should be directly proportional to field flux (and hence, also directly proportional to the field current). imdb can you keep a secret
