Shunt excitation
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). WebSeparately excited dc motor has field coils similar to that of shunt wound dc motor. The name suggests the construction of this type of motor. Usually, in other DC motors, the …
