Compound DC Generator
In series wound generators, the result voltage is directly proportional to the load current. In shunt wound generators, the result voltage does not correlate to the load current.
A combination of these two types of generators can overcome the drawbacks of each. This set of windings is known as a compound DC generator.
Compound generators use both series and shunt field windings. One winding is connected in series with the armature, while the other is connected in parallel up with the armature. These DC generators may be classified into two types: short shunt compound generators and long shunt compound generators.
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.
