Construction And Working of a DC Generator
What is a DC generator?
A DC generator is a machine that converts mechanical energy into direct current (DC) electrical energy. It operates on the principle of electromagnetic induction, generating a voltage when a conductor moves inside an magnetic field.
Where are DC generators used?
DC generators were generally used in different applications, including early electrical power age and as a power hotspot for battery charging. however, they have generally been replaced by more efficient and flexible devices like alternators and rectifiers.
How does a DC generator work?
DC generators work in view of Faradayâs law of electromagnetic induction. At the point when a guide moves in an attractive field, an electromotive power (EMF) is prompted. In a DC generator, this EMF is then changed over into an direct current using a commutator.
What are the types of DC generators?
There are two main types of DC generators: series-wound and shunt-wound. Series-wound generators have the field winding connected in series with the armature, while shunt-wound generators have the field winding connected in parallel with the armature.
What is the role of a commutator in a DC generator?
The commutator in a DC generator is a rotating switch that switches the ongoing course in the coil windings. It ensures that the generated current flows in a one direction in the external circuit, making a constant and unidirectional flow of electricity.
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 generatorâs converse function. The basic purpose of the motor is to convert electrical energy into mechanical energy. Generators and motors have many properties.
