What is Electric Generator?

An Electric Generator is a device that uses mechanical energy to produce electrical energy. This procedure works on the theory of electromagnetic induction, which states that a change in magnetic flux via a coil produces an electromotive force (EMF). Steam turbines, water turbines, internal combustion engines, wind turbines, and hand cranks can all provide the mechanical energy required to power a generator.

Parts of Electric Generator

There are various parts in the generator, which are listed below –

• Rotor
• Stator
• Slip Ring ( In AC Generators )
• Field Winding
• Commutator ( In DC Generators )

Types of Electric Generator

There are two types of generator –

1. DC Generator: This types of generator produces direct current.
2. AC Generator: This types of generator produces alternating current.

Applications of Generator

Below we listed some important applications of this electric machine –

1. The grid’s electricity is generated by large-scale electric generators.
2. Used to provide backup power for homes, businesses, and outdoor activities.
3. Wind turbines and hydropower plants use generators to convert the kinetic energy of wind and water into electricity.
