Short-Shunt Compound DC Generator
Short Shunt Compound DC Generators use the shunt field winding in parallel with the armature winding, as seen in the picture below. The series field current is equal to
Isc = IL.
The shunt field current is equal to
Ish = (V + Isc Rsc)/Rsh.
Armature current is equivalent to,
Ia = Ish + IL
Voltage across the load equals
V = Eg-Ia Ra-Isc Rsc
The power generated is equivalent to:
Pg = Eg x Ia.
The power given to the load is equal to:
PL = V x IL
Construction And Working of a DC Generator
In 1831, Michael Faraday, a British physicist, devised the electromagnetic generator. The primary function of this device is to convert mechanical energy to electrical energy. There are several types of mechanical energy sources available, including hand cranks, internal combustion engines, water turbines, and gas and steam turbines. The generator provides capacity for all electrical power networks. An electric motor should be able to perform the generator’s converse function. The basic purpose of the motor is to convert electrical energy into mechanical energy. Generators and motors have many properties.
