PMD4807PTB2-A.(2).U.GN

DC fans refer to fans that use DC voltage, mainly 12V, 24V, 48V and other low voltage voltages. At present, the global DC fan application field is relatively wide. High-end industrial DC fans generally adopt high-performance brushless DC motor technology and effective external controllers to support higher air volume, higher static pressure and speed control applications. PMD4807PTB2-A.(2).U.GN belongs to a high-end industrial DC fan, and it is widely used in computer, printer, router, game console, network power, power distribution control cabinet, robot etc.

PMD4807PTB2-A.(2).U.GN DC fan has a variety of dynamic characteristics. Generally, it has features of low power consumption, low noise and high cooling efficiency. It consists of the following components: a six-pole DC brushless motor; a centrifugal impeller with an impeller width of 47mm and seven blades; and a fan housing. The fan housing is generally made of ABS high-strength plastic material and has a modern appearance design. The total length of the fan is 45mm, and the weight is about 45g.

The working principle of the PMD4807PTB2-A.(2).U.GN is the same as that of other DC fans. Taking the fan as an example, the electric current first enters the motor and the rotor inside the motor. The main body of the motor is composed of a stator and a rotor. The DC current flows through the electromagnet of the stator. In the presence of an electromagnetic field, the rotor turns. The turning of the rotor will produce air. The blades of the fan impeller will be pushed by the air to rotate. Air is driven to be pumped out by the rotation of the blades. When the external environment has certain temperature, air generates heat when expanding. Thus, the fan can work to dissipate heat and maintain stable temperature of the external environment.

In conclusion, PMD4807PTB2-A.(2).U.GN is a DC fan belonging to the high-end industrial DC fan. It has advantages of low power consumption, low noise and high cooling efficiency. Its working principle is the same as other DC fans, and it is widely used in various occasions.
