 2. Understanding 12 Volt DC Blower Fans

 2.1 Basics of DC Blower Fan Operation

DC blower fans, specifically those operating at 12 volts, rely on the principle of electromagnetic induction. The 12 - volt DC power source supplies electrical energy to the motor within the fan. The motor, which consists of a stator and a rotor, converts this electrical energy into mechanical energy. In a brushed DC motor, the stator has a stationary magnetic field, and the rotor, with windings, rotates within this field. The brushes and commutator assembly in a brushed motor ensure that the current in the rotor windings is reversed at the appropriate intervals, maintaining the rotational motion.

In brushless DC motors, which are becoming increasingly popular in 12 - volt DC blower fans, the commutation is achieved electronically. Hall effect sensors are often used to detect the position of the rotor. Based on the rotor's position, an electronic controller switches the current in the stator windings, creating a rotating magnetic field that drives the rotor. This electronic commutation eliminates the need for brushes, resulting in reduced wear and tear, longer lifespan, and higher efficiency.

 2.2 Why 12 Volts?

The 12 - volt standard is widely adopted in many applications for several reasons. In the automotive industry, most vehicles operate on a 12 - volt electrical system.
