What Are The Two Main Parts Of An AC Generator?

There are two main components in the generator,

the rotor and the stator

. The generator must also have a source of DC current to magnetize the rotor, called the exciter.

What are the basic parts of an AC and DC generators?

• Stator. The main function of the stator is to provide magnetic fields where the coil spins. …
• Rotor. A rotor in a DC machine includes slotted iron laminations with slots that are stacked to shape a cylindrical armature core. …
• Armature Windings. …
• Yoke. …
• Poles. …
• Pole Shoe. …
• Commutator. …
• Brushes.

What are the main parts of AC generator?

• Field.
• Armature.
• Prime Mover.
• Rotor.
• Stator.
• Slip Rings.

What are the two types of AC generators?

• Induction generators.
• Synchronous generators.

What are the part of a generator?

Generators contain

an engine, a fuel system, an alternator and a voltage regulator

, as well as cooling, exhaust and lubrication systems.

What is the principle of an AC generator?

AC generators work on the principle of

Faraday’s law of electromagnetic induction

. This law states that electro motive force is generated in a current carrying loop that is placed in a uniform magnetic field.

What is the principle of generator?

Electric generators work on the principle of

electromagnetic induction

. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.

What are the three major parts to an AC generator?

The basic parts of an AC generator are

the mechanical power, the magnets and one or more rotors

. Without any of these parts, electricity can’t be produced. Each part has its own role.

What is AC generator with diagram?

The principle behind A.C. generators is electromagnetic

induction

. When a closed coil is rotated in a uniform magnetic field with its axis perpendicular to the magnetic field, the magnetic flux linked with the coil changes and an induced emf and hence current is set up in it. The following diagram shows an A.C.

Where is DC generator used?

They are used as portable generators where low power supply is required. They are used in

motorcycles as dynamos

, in toys such as remote control cars and in appliances such as electric shavers. These generators find uses in arc welding in which huge drop in voltage and constant current are required.

Which is better AC or DC generator?

AC generators are very efficient

as the energy losses are less. Due to sparking and other losses like copper, eddy current, mechanical, and hysteresis losses DC generators are less efficient. In an AC generator, the electrical current reverses direction periodically.

What is the most common type of AC generator?

Rotating Field Generator

The rotating field AC generator

as illustrated in Figure 2 is by far the most widely used generator. In this type of generator, direct current from a separate source is passed through windings on the rotor by means of slip rings and brushes.

Does generator produce AC or DC?

While generators feature a stationary field in which the conductor rotates to produce electromagnetic induction, an alternator’s entire magnetic field turns with its conductors remaining stationary.

Generators are capable of both AC and DC power

.

Does the generator really generate something?

Generators don’t actually create electricity. Instead, they

convert mechanical or chemical energy into electrical energy

. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.

What is the main function of a generator?

Generators

create electrical energy to power appliances running on electricity by burning the fuel it uses for producing electricity

. The generator includes different elements like a fuel system, engine, voltage regulator, alternator, a control panel, lubrication system, cooling, and exhaust system.

What are the similarities and difference between electric motor and generator?
