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 –
- DC Generator: This types of generator produces direct current.
- AC Generator: This types of generator produces alternating current.
Applications of Generator
Below we listed some important applications of this electric machine –
- The grid’s electricity is generated by large-scale electric generators.
- Used to provide backup power for homes, businesses, and outdoor activities.
- Wind turbines and hydropower plants use generators to convert the kinetic energy of wind and water into electricity.
