At the heart of a brushless DC cooling blower fan is a brushless DC motor. Unlike traditional brushed DC motors, which rely on mechanical brushes for commutation, brushless DC motors utilize electronic commutation. The motor consists of a rotor with permanent magnets and a stator with windings. Hall effect sensors are commonly employed to detect the position of the rotor. Based on the signals from these sensors, an electronic control circuit precisely switches the current in the stator windings. This creates a rotating magnetic field that interacts with the magnetic field of the rotor, driving its rotation.

The use of electronic commutation offers several advantages. Firstly, it eliminates the issue of brush wear, which is a major limitation in brushed DC motors. This significantly extends the lifespan of the motor, making brushless DC motors more reliable for long - term operation. Secondly, brushless DC motors are more energy - efficient. The precise control of the current in the windings allows for better utilization of electrical energy, reducing power losses and increasing the overall efficiency of the fan.
