DC fans refer to fans that use direct current to drive the motor. Compared with general electric fans, DC fans have the advantages of low noise, low power consumption and low vibration. In the figure, FDD1-17251CBAW34-L is a DC fan.

Application Field

The motor drives the fan blades of DC fans by using the current. In general, there are two types of fan blades: forward curved blades and backward curved blades. According to the life expectancy indicated in the application manual of FDD1-17251CBAW34-L, this type of DC fan is suitable for cooling and air conditioning systems, cooling towers, smoke exhaust systems and other ventilation systems.

Working Principle

The operation principle of DC fan is the same as that of AC fan. The general principle is that when the DC voltage enters the fan through the small power supply, the current will drive the fan blades, so as to drive the surrounding air to rotate, which makes the air heat convection. Different types of fan have different speeds, so different ventilation needs can be met by adjusting the current and voltage.

Conclusion

DC fans have the advantages of low noise, low power consumption and low vibration, and are suitable for cooling and air conditioning systems, cooling towers, smoke exhaust systems and other ventilation systems. FDD1-17251CBAW34-L is such a type of DC fan. When DC voltage enters the fan through the small power supply, the current will drive the fan blades, so as to drive the surrounding air to rotate, which makes the air heat convection.
