  • Intelligent Thermal Management Using Brushless DC Fans
    The brushless DC fan (BDC Fan) has become the air mover of choice in computing equipment, office automation products, home entertainment systems, and the like. Unlike conventional DC fans, the BDC fan is mechanically robust because it contains no rotating commutator/brush assembly to shed dust

  • Brushless DC Motors
    motors generally contain a three-phase winding, although some operate four phase. Brushless motors powering small fans and other constant-speed equipment are often two phase. Power for brushless motors generally is a trapezoidal ac wave form, but some of the motors operate with sine waves
  • How to select Hall-effect sensors for brushless dc motors
    Brushless dc (BLDC) motors need to operate more efficiently as energy and cost. savings becomes a bigger concern for designers of electronic devices. One way to. help ensure greater efficiency is by selecting the correct bipolar latching Hall-effect sensor IC for electronic commutation in BLDC
