Fan DC means that the power supply of the fan is direct current, that is, the voltage is constant. In contrast, fan AC, the power supply is alternating current, the voltage will constantly change.DC fan has the advantage of low power consumption, small size, long effective life, suitable for some need to run for a long time in the scene, such as industrial production lines.
What is the working principle of fan DC?
The Fan DC motor uses a brushless DC motor, which means that magnetic poles are installed on both the rotor and stator of the motor, so there is no need to transfer electricity through carbon brushes, etc. The permanent magnets on the rotor of the motor and the coils on the stator will constantly change polarity through the electronic controller, which makes the motor rotate continuously to generate wind power.
What are the application areas of fan DC?
Fan DC is mainly used in some scenarios that require long time continuous operation, low power consumption requirements and small size. Such as electronic equipment, computer cooling, computer room ventilation, industrial production lines, medical equipment and so on. In these scenarios, the DC fan can not only effectively cool down and ventilate, but also ensure long time operation and improve the stability and service life of the equipment.
