Fans control board
1, smart fan is equipped with automatic sensing temperature regulation air volume also equipped with a WiFi function, the user downloads the corresponding APP on the phone, you can use the phone remote control switch, wind speed, timing, appointment and other intelligent features of the fan.
2. The main components of the electric fan are: AC motors.
3, its working principle is: the power coil in the magnetic field and rotate.
4. In the form of energy conversion, the electrical energy is mainly converted into mechanical energy. At the same time, because the coil has resistance, it is inevitable that some of the electrical energy must be converted into thermal energy.
