  • Selecting Dc Brush and Brushless Motors
    whether to employ brushless or brushed dc, or stepper motors. Stepper motors are generally considered specialpurpose devices because they can't handle large inertial loads very well. And operation near their maximum torque ratings can take some finesse. * Shaft-bearing systems, commutation, and motor...
  • 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 Blowers: The Real & Hidden Advantages (.pdf)
    For years brushless DC tubeaxial (box) fans have been growing in use, importance and market share for cooling electronics in cabinets and enclosures for computers, telecommunications and medical equipment. As more electronics, at higher package densities, are incorporated into appliances the impact...
