Structure and operating principle of electric fans

Electric fans are an indispensable electrical device in our daily lives. Electric fans create cool air to cool people and everyone needs it when the weather is hot.

Everyone knows electric fans, so how many people know the structure of electric fans and the principle of operation of an electric fan that we still use?

Join us to learn the principles and structure of an everyday electric fan used in the article below.

To talk about the structure of a fan, we can say this is a very simple electrical device and is structured as follows:

  • The plastic case you see with the naked eye
  • Insert the rotor to protect us against the rotor blades
  • Propeller
  • Fan motor
  • Fan control bugs by board or by switch
  • Motor turns right to left
  • (Function) switch for the engine to turn right and left
  • Capacitor (capacitor for fan motor)
  • Power cord
  • Remote control (whether there are any or not)

This is the whole structure of a most common electric fan. Only with the naked eye can we see almost all the structure of an electric fan. So is this simple structure when the fan is broken easy to repair? Invite you to add more principles to know how to use below.

The principle of operation of an electric fan

To talk about the principle of operation of the electric fan is extremely simple, so we can check and repair the electric fan right after watching this article.

Principles

We plugged in the power source at this time the fan is not running and you need to turn on the number with the push button, or use the remote control depending on the different types of fans.

If you press number 1 this time the fan will dial 1, press 2 the fan will dial 2, the number 3 fan will dial 3 . Press the fan function will turn right and left.

Usually the electric motor will have 3 numbers, so the electric motor is also wrapped in 3 coils running including 3 wires and 1 capacitor wire, 1 common wire that powers the machine first.

When you turn on the number of switches will communicate and power on the corresponding number you turn on and this time the fan will rotate with the wind corresponding to the manufacturer has set.

When you press the power button at this time, the 220v power will supply the internal rotation motor to make the fan move continuously left and right.

  • STEEL CORE
  • WIRE WIRE

The electric motor in the fan is the most important and valuable device of an electric fan. 90% of electric fans are damaged due to the fan motor being the main cause of the fan not running.

Some common problems in electric fans you can handle themselves

  • Electric fan has broken wing: Now you just need to replace the new fan, the fan will have the wind blowing out again
  • Function does not work: You remove and replace the internal rotation motor
  • The motor does not work or runs but is weak: With this error you need to replace the new capacitor to try if the problem does not work, this is the phenomenon of your home motor malfunction. You bring them to a civil electrical store and tell them to rewind the engine.
