• FG stands

    FG stands  is the abbreviation of Frequency Generator. It is called square wave or F00 wave. It is a square waveform generated while the fan rotates one cycle. Its signal frequency follows the fan rotating. With this function, your electric control circuit can always read the fan rotation, and th...

  • What is PWM in cooling fan?

    Pulse Width Modulation is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. ...

    What is a Bearing?

    Sleeve bearings (sometimes called bushings, journal bearings or plain bearings) facilitate linear movement between two parts. Sleeve bearings consist of a metal, plastic or fiber-reinforced composite sleeves that reduce vibrations and noise by absorbing friction between two moving parts using a s...

    Explanation of the waterproof IP rating of the brushless axial cooling fan

    Industrial cooling fans are widely used, and the application environment is also different. In harsh environments, such as outdoor, humid, dusty and other places, general cooling fans have a waterproof rating, which is IPxx. The so-called IP is Ingress Protection. The abbreviation for IP rating i...
