DC Fans

DC fans are one of the most widely used types of axial fans in small applications, and they are used for commercial and industrial applications, such as machine cooling, electronic cooling, and home ventilation. The OD7025-12LB02A is a popular and economical DC fan used in many applications. This article will discuss the application field and working principle of this fan.

Application Field

The OD7025-12LB02A fan is designed for applications that require low speed and high airflow. It is ideal for cooling electronics, such as server cabinets, as well as ventilation for small areas. It is also suitable for use in automotive engines, where it is used to cool the electronic components of the engine. In addition, the fan can be used in computers, televisions, and other electronics.

Working Principle

The OD7025-12LB02A fan is a DC motor-driven fan, which means that it is operated by an electrical current. The fan consists of four main components: a stator, rotor, fan blades, and an electronic circuit board. The stator is a ring-shaped part that holds the rotor in place. The rotor consists of a metal cylinder with magnets that is attached to the fan blades. The electronic circuit board contains two resistors, which allow the motor to be controlled by the voltage received from the power supply.

When the power supply is connected and the motor is activated, it creates an electromagnetic field. This field causes the rotor to rotate, which creates the airflow through the fan. The current from the power supply determines the speed of the fan. The voltage can be adjusted to increase or decrease the speed of the fan according to the desired airflow.
