Quick Answer: What do you think is the role of electric motor in the appliances?

An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. … Motors are used in a wide range of applications, such as fans, power tools, appliances, electric vehicles, and hybrid cars.

What is the role of electric motor in appliances?

An electric motor is a device used to convert electrical energy to mechanical energy.

What is the importance of electric motor in our daily household chores?

Electric motors are extremely important in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.

What is the role of the electric motor in a refrigerator?

Refrigerator. Another common household appliance, the refrigerator needs small motors to operate its compressor. This compresses the refrigerant chemical into a liquid to create the cold temperature that helps preserve fresh goods.

How does motor work in these appliances?

Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.

What are the advantages of electric motor?

Some of the advantages of electric motors are as follows: High efficiency: Electric motors are highly efficient devices mainly depending on their operation conditions and the size of the motor. These motors do not use fuel and they do not require engine-oil maintenance like most of the other electrical devices.

What is the importance of motor?

Motor skills are essential for baby’s physical strength and movement. Motor skills are used everyday throughout our lives. They help us move and do everything from lifting heavy items to typing on a keyboard. Motor skills and motor control begin developing after birth, and will progress as children grow.

What is the main role of electricity in the engine?

The Alternator – The alternator is the main source of power whenever the engine is running. It is the alternator that sends electricity to the battery, giving the charge that it needs to run properly. If the alternator is weak, your battery will lose charge quickly and soon, your vehicle will be unable to start.

How did the electric motor change the world?

The induction motor is one of the most important inventions in modern history. It turned the wheels of progress at a new speed and officially kicked off the second industrial revolution by drastically improving energy generation efficiency and making the long-distance distribution of electricity possible.

Why was the invention of the electric motor important?

Essentially, Faraday’s invention of the electric motor, which converted electric current into mechanical energy, took existent ideas and theories about electricity and made them concrete, practical and useful.

Where is the electric motor in a fridge?

Popular General Electric Refrigerator Motors. This 115-volt 60Hz evaporator fan motor is located in the back of the freezer and circulates air over the refrigerator coils. These coils will convert the heat into cool air, which is then circulated.

How does an electric refrigerator work?

Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. … When you release the contents into the lower pressure open space, it turns from a liquid to a gas.

Do fridges have electric motors?

How does a refrigerator use energy? There are three components in the refrigerator that draw energy: the compressor, the condenser fan, and the evaporator fan. … The condenser fan’s motor uses electricity to run and must be on whenever the compressor is running and pumping refrigerant through the condenser coils.

How do electric motors work physics?

A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.

Which motor is used in home appliances?

Single-phase induction motors are used in household applications due to their robust and simple construction and to their capability for being attached directly to the single-phase grid without using power converters [1, 2].
