Principle of electric fan

We know that the most important hardware of an electric fan is the motor, and only the rotation of the motor can drive the fan blades to rotate. Why does the electric fan motor turn? The principle is: the energized coil rotates under force in the magnetic field. After the electric fan is energized, the alternating positive and negative alternating current generates a magnetic field, which makes the motor energized coil rotate under force, and the rotating shaft rotates together with the fan blades, converting electrical energy into mechanical energy. In the process of energy conversion, a part of the energy is converted into heat energy, which is transferred out, and the heat is released to the outside.
Electric fan heating not cooling

We use electric fans to cool down, not because the electric fan itself can cool, not only does it not cool, but the electric fan also increases heat due to energy conversion. But why does electric fan blowing make people feel cool? Here is the principle of evaporative heat absorption. However, when people feel hot, they will expel sweat outward. The fan accelerates the flow of air to promote sweat evaporation and absorb body heat to achieve cooling. | modern box fan suppliers
