Working principle of ceiling fan

When the ceiling fan is supplied with power, the power will cause the fan motor to start and begin to rotate in the direction set by the manufacturer. The motion of the motor is transmitted to the blades and causes the blades to rotate, creating a cool breeze.

Therefore, the airflow of the fan is strong or weak due to the fast or slow rotation of the motor through the control of the gearbox. In addition, the strength of the wind also depends on the design, as well as the direction of rotation of the fan.
