DC Fans are a kind of electronically commutated motor, which integrate the speed controling technology into motor design. ASFN10B92 is one of the most popular DC Fans in the market. It is widely used in commercial or home air-conditioning system.

The working principle of ASFN10B92 can be split into two parts. The first part is the feedback circuit. This circuit consists of a photoelectric device, a components board, and Hall effect generator. The DC fan is energized by the voltage of the components board, and the needed current is provided by the Hall effect generator.

The second part of the working principle is the speed control. It is accomplished by the photoelectric device. This device measures the pressure changes in the air and produces an oscillating voltage. This voltage is fed to the speed control circuit, which adjusts the speed of the fan accordingly.

In conclusion, ASFN10B92 DC Fans has several features that make them ideal for cooling applications such as centrifugal blowers, tower fans, evaporative coolers, and ventilation products. Its feedback circuit and speed control circuit enable the fan to work at the desired speed, while its high-performance motor is designed to provide a very low noise level. This makes it suitable for all types of air-conditioning and cooling systems.
