What do you think is the role of the electric motor?
An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
What is the role of the electric motor in a refrigerator?
The refrigerator compressor is both a motor and a pump that move the refrigerant through the system. … The compressor pushes out the hot, compressed gas through the outside metal coils (tubes) on the back or bottom of the refrigerator. These coils allow the heat to dissipate into the surrounding air.
In which appliances is the electric motor used?
Devices in which electric motors are used
- Water pumps.
- Electric fans.
- Electric mixers.
- Washing machines.
What are the disadvantages of electric motors?
Disadvantages can include the need for a high starting current, as well as lower efficiency due to a need for magnetization. It is important that your service and support protocols anticipate these considerations, and others, to maximize performance and reliability.
How important is the electric motor in our daily lives?
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.
Does a fridge have a motor?
The condenser fan motor is found in the back of the refrigerator, and it moves air across the compressor and the condenser to keep them cool. If the motor has failed, the condenser and the compressor will run hot, and this can cause the refrigerator not to cool. This is an OEM part from the manufacturer.
What type of motor is used in refrigerator?
Single phase induction motor is used in household refrigerator.
|Single phase motor||Application|
|Capacitor run motor||Compressors, Conveyors, Refrigerators, Air conditioners, Ceiling fans|
|Shaded pole motor||Hair dryers, Toys, Record players, Small fans, Electric clocks|
Does refrigerator work on electric motor?
Usually, a refrigerator is a device that is used to cool things. But according to the second law of thermodynamics, a refrigerator is a device which is used to turn mechanical work into heat. Therefore, we can say that a refrigerator is a heat engine that works in a backward direction.
In what ways can a motor be made more powerful?
- We can make a motor more powerful by following ways:
- If the coil is wound on a soft iron core, the strength of magnetic field increases.
- By increasing the number of turns of insulated copper wire of the coil.
- By using a powerful electromagnet in place of permanent magnet.
Where is electric cell used?
Applications of electrochemical cells: These cells are used in torches, digital cameras, hearing aids, batteries, watch, video games. These cells are also being used in medical implants in the body. These cells are also used in satellites, rocket launch equipment.
