What is a DC Generator?
An electromechanical energy conversion device known as a DC generator uses electromagnetic principles to convert mechanical power into DC electrical power. According to the electromagnetic induction theory, an EMF is induced in a conductor when the magnetic flux connecting them changes. This is how a DC generator works. In a DC generator, there are two windings: the field and the armature.
The EMF made in the armature Winding of a DC generator is rotating and is switched over completely to coordinate voltage by a commutator introduced on the generator’s shaft. A DC generator’s armature winding is on the rotor, while the field winding is on the stator.
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.
