What principle is the electric fan made of?

Fan. It is manufactured by cutting magnetic inductance lines, that is, the principle of electromagnetic induction.

The principle of electromagnetic induction refers to the amount of magnetic flux placed at a change.

, an electromotive force is generated. This electromotive force is called induced electromotive force or induced electromotive force. If this conductor is closed into a loop, the electromotive force drives the flow of electrons, resulting in an induced current (induced current).

In fact, there are many coils on the fan motor that are wound in a specific order, which is the stator of the electronics. Alternating current.

After the machine is energized, an electromagnetic field will be generated, and due to the characteristics of the alternating current itself, a rotating magnetic field will be generated with the change of time, and the coil when energized will form a closed loop, which will rotate under the force of the magnetic field, and then rotate the rotor made of silicon steel sheets, thereby driving the blades to rotate, and the fan will begin to operate normally.

The main component of the electric fan is: AC motor.

Its working principle is that the energized coil rotates under force in a magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and at the same time, because the coil has resistance, it is inevitable that a part of the electrical energy will be converted into internal energy.

Household electric fans use alternating current, while AC motors do not use permanent magnets, but use the principle of electromagnetic induction. It uses the current of alternating current to change with time to generate a rotating magnetic field, and then rotates the rotor made of silicon steel sheets.

What is the principle of making an electric fan? Master, live demonstration.

See below how it works:

The working principle of the electric fan is that the energized coil in the AC motor rotates under the force of the magnetic field, converting the electrical energy into mechanical energy, and at the same time, due to the resistance of the coil, a part of the electrical energy is converted into thermal energy. In addition, low-power motors such as DC motors and brushless DC motors are increasingly widely used in small fans.

Introduction: I remind you that you must not be frightened by this lofty theoretical topic, you must read it carefully As far as you know, the structure of the electric fan is very complex, and I have studied its working principle in order to uncover the mystery of the electric fan.

1.First I removed the casing of the electric fan and found several important parts - the timer, the motor, the wiring board.

2.Separate the terminal strip from the motor.

3.Focus on disassembling the motor.

4.Teardown the timer.

5.Study the circuit board.

1.The fan is mainly composed of a fan head, a fan blade, a net cover and a control device, and the fan head includes an electric motor, a front and rear end cover, and a moving head air supply mechanism. Electric fan is a kind of household appliance that uses an electric motor to drive the fan blade to rotate to accelerate the circulation of air, which is mainly used to cool off the heat and dredge the air.

2.The main component of the electric fan is: AC motor.

Its working principle is: the energized coil rotates under the force of the magnetic field, converting electrical energy into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that a part of the electrical energy will be converted into thermal energy. If it is assumed that there is no heat transfer between the room and the outside world, the indoor temperature will not only not decrease when the electric fan is working, but will increase.

3.Electromagnetic induction principle: when a part of the conductor in the closed circuit is cut by the magnetic inductance line, the induced current will be generated in the circuit.

4.Lenz's law: The magnetic field force (ampere force) on the induced current on a moving conductor always resists (or hinders) the movement of the conductor.

5.Why do people feel cool when they use electric fans? Because there is a lot of sweat on the surface of the human body, when the electric fan is working, the indoor air will flow, so it can promote the rapid evaporation of sweat, as we all know, evaporation needs to absorb a lot of heat, therefore, we will feel cool.

Electric fans are electrical appliances that we often use in our daily life, and in a room with an air-conditioned room, turning on the electric fan can effectively reduce the indoor temperature. So how does an electric fan work? What are the classifications of electric fans?

1. What is the working principle of the electric fanThe electric fan has an electric coil, which can rotate randomly as long as it is subjected to force in the magnetic field, and can convert the electrical energy into mechanical energy after being energized, and the motor drives the fan blades to rotate, so as to accelerate the air circulation. The reason why the human body feels cooler is mainly because there is a lot of sweat on the surface of our body, and when the electric fan is running, it will make the air circulate, which will promote the evaporation of sweat, so it will make us feel cooler. 2. What are the types of electric fans 1. Floor fans are also a more common type, which has intelligent and traditional mechanical types, but the air volume will be larger when running, and the noise generated is relatively low.

And it has a chassis, so it will be more stable, bring a better cooling effect in the hot summer, and is suitable for use in the living room or office. 2. Desk fan is also a relatively common type, its size is relatively small, and the noise is not particularly large when running. At the same time, it is relatively safe to use, but also classic and durable, some of this kind of table fan can shake the head, and some are fixed.

3. In addition, there are bladeless fans, which are more popular in the current market, with a relatively novel design, a very prominent sense of fashion, and a relatively beautiful appearance, giving people a visual enjoyment. Relatively speaking, it is more convenient to clean, it is not easy to pinch children's fingers, and the energy consumption is relatively low, so it is more energy-saving and environmentally friendly. However, relatively speaking, ** is slightly higher.

4. There are also ceiling fans, which are generally installed directly on the ceiling, which brings strong wind and is suitable for installation in larger spaces, such as factories or canteens. Summary: The above introduction is the working principle of electric fans, and what are the types of electric fans, there are still many types, so they are used in different places, and consumers can choose according to their actual needs.

Electric fan, also known as fan and fan, is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate the circulation of air, mainly used to cool off the heat and circulate the air. It is widely used in homes, classrooms, offices, shops, hospitals and hotels.

A fan is mainly composed of components such as a fan head, blades, grille, and controls. The fan head includes an electric motor, front and rear end covers, and a moving head air supply mechanism. The main components of an electric fan are:

AC motors. Its working principle is that the energized coil rotates under force in a magnetic field.

Electrical energy is converted into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that some of the electrical energy will be converted into thermal energy.

Common household fans are essentially axial fans, i.e., the direction of the wind is parallel to the axis of rotation of the fan blades.
