The electric fan is referred to as an electric fan, also known as a fan or a fan. It is a household appliance that uses an electric motor to drive the fan blades to rotate to achieve accelerated air circulation. Widely used in homes, classrooms, offices, shops, hospitals and hotels.
The fan is mainly composed of fan head, blade, net cover and control device. The fan head includes a motor, a front and rear end cover, and a shaking head blower mechanism. The main components of electric fans are: AC motors. Its working principle is: the energized coil rotates under force in a magnetic field. Electrical energy is converted into mechanical energy. At the same time, because of the coil resistance, a part of the electrical energy is inevitably converted into thermal energy.
Common household electric fans are essentially axial fans, that is, the direction of wind flow is parallel to the axis of rotation of the fan blades.
