 2. Understanding Mini DC Blower Fans

 2.1 Basics of DC Blower Fan Technology

DC blower fans operate based on the principle of converting electrical energy into mechanical energy to generate air movement. A DC motor, which is the heart of the fan, drives the rotation of an impeller. In the case of mini DC blower fans, the design is optimized to provide sufficient air - flow and static pressure in a compact form factor.

There are two main types of DC motors used in these fans: brushed and brushless. Brushed DC motors use mechanical brushes to transfer electrical current to the rotating armature. While they are relatively simple and cost - effective, they suffer from issues such as brush wear, which can limit their lifespan and increase maintenance requirements. Brushless DC motors, on the other hand, use electronic commutation. They have a rotor with permanent magnets and a stator with windings. The electronic control circuit monitors the position of the rotor and switches the current in the stator windings accordingly, creating a rotating magnetic field that drives the rotor. This technology offers several advantages, including higher efficiency, longer lifespan, and better speed - control capabilities.

 2.2 Why Miniature Fans?

Mini DC blower fans are designed to be small in size, typically with dimensions ranging from as small as 20x20x10mm to around 60x60x25mm.
