An electric fan is referred to as an electric fan, and is called a fan in Japan and Korea. It is a household appliance that uses a motor to drive the fan blades to rotate to accelerate the circulation of air. It is mainly used to cool down and circulate the air. Widely used in homes, offices, shops, hospitals, hotels and other places. The electric fan is mainly composed of fan head, blades, grille and control device. The fan head includes a motor, front and rear end covers, and a oscillating air supply mechanism. The main components of an electric fan are: AC motor. Its working principle is: the energized coil is forced to rotate in the magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy. At the same time, because the coil has resistance, it is inevitable that part of the electrical energy will be converted into heat energy.
