The Principle Of The Fan

The working principle of the fan is mainly to drive the fan blades to rotate through the motor to form an airflow. When the current passes through the coil in the motor, a magnetic field is generated, which acts on the rotor to rotate, thereby driving the fan blades to rotate. The fan blades are usually designed with a certain tilt angle to more effectively stir the air and form a cool wind.

The core components of the fan include the motor, fan blades, wires and power supply. The motor is the "heart" of the fan. The magnetic field generated after power is turned on drives the rotor to rotate, thereby turning the fan blades. The tilt angle design of the fan blades allows the air to be effectively pushed when rotating to form an airflow.

The wind speed adjustment of the fan is achieved by changing the power supply voltage of the motor. Increasing the voltage will increase the motor speed, the fan blades will rotate faster, and the wind will be stronger; conversely, reducing the voltage will slow down the motor speed and make the wind softer.

The application scenarios of fans are very wide, mainly used in homes, classrooms, offices, shops, hospitals and hotels for cooling and circulating air.
