ASFN86371

DC fans, such as the ASFN86371, are becoming increasingly popular in many industrial and commercial applications. These fans offer more efficient cooling and airflow than their AC counterparts. This article will discuss the application field and working principle of the ASFN86371.

Application Field

The ASFN86371 is a three-phase brushless direct current (DC) fan. It is designed for cooling and ventilation of high-power electronic devices in a variety of applications, such as LED lighting fixtures, server cabinets, and industrial automation equipment.

Working Principle

The ASFN86371 utilizes three-phase brushless DC motor technology. This type of motor eliminates the need for brushes and external commutators, making it more effective for cooling. The motor features a three-pole magnetized rotor and eight stator windings that generate an alternating-current field. This field interacts with the rotor, creating an electromagnetic torque that drives the fan.

The motor is configured with an external electronic controller, which acts as the central hub of the system. The controller monitors the motor\'s temperature and adjusts the speed accordingly. It also provides protection against over-heating and overheating and features a low-noise operation.

The ASFN86371 can be used for a variety of purposes, depending on the application. For cooling purposes, the fan can generate airflows up to 95CFM at 0.27inH2O static pressure. For ventilation purposes, the fan can produce up to 165CFM at 0.54inH2O static pressure.

Conclusion

The ASFN86371 is a powerful and efficient three-phase brushless DC fan that is ideal for cooling and ventilation applications. It features an external controller which monitors the motor\'s temperature and adjusts the speed accordingly. Furthermore, the fan can generate airflows up to 95CFM at 0.27inH2O static pressure for cooling, or up to 165CFM at 0.54inH2O static pressure for ventilation.
