DC Fans

Electric fans, as the most common cooling equipment, are widely used in many electric fields and are essential in electronic products. DC fans refer to the use of direct current as the working voltage to make it rotate. Therefore, DC fans play an important role in ensuring normal operation of electronic products.

3254J/2H3P application field and working principle

3254J/2H3P is a kind of DC fan which is widely used in products such as telecommunication system, set-top box, server, router and so on. It adopts the magnetic flap and liquid crystal display technology, so the brushless motor can run in -10℃~+70℃ temperature environment. 3254J/2H3P is of high frequency DC fan design, with speed of 1500-3000 rpm, rated voltage DC12V, rated current 0.17A, noise level 27db ± 10%.

The working principle of 3254J/2H3P is the rotor of the brushless fan motor is fitted with permanent magnet blocks, thus forming a spiral magnet field which rotates constantly. When DC current of a certain magnitude is connected into the stator, a spiral magnetic field is generated in the stator magnetic yoke, thus producing a rotating magnetic field. This will serve as an attractive force for the permanent magnet blocks, thus driving the rotor to rotate.

3254J/2H3P has the characteristics of low noise, good air volume, low power consumption, high cost performance and strong practicability. It has wide range of operating temperature, low start voltage, and can also effectively prevent the dust from entering the fan and prolong its service life, thus becoming the ideal choice for use in the electronic industry, telecommunications systems, set-top boxes and other products.
