DC fans, also known as the electric fan, is an electric fan driven by direct current with a ball bearing motor. The most common type of DC fan used in cooling applications is made from an impeller with several blades, which is typically located inside a cage-like outer structure. The motor turns the blades, creating a draft of air, which creates a cooling effect.

DC fan motors are typically made up of permanent magnets, wound coils and an armature. The permanent magnets create a static field which is used to attract and repel the armature, which rotates as a result. As the armature rotates, it turns the fan blades which in turn move air and create a draft.

The most common type of DC fan used for cooling applications is the 17000B12A version. This fan is designed for use in cooling applications with a maximum airflow of 3.3 cubic meters per minute. The 17000B12A fan has a brushless motor which means it is more efficient and operates quietly.

The working principle behind the 17000B12A fan is that the permanent magnets in the motor create a static field which is used to attract and repel the armature. As the armature rotates, it turns the blades of the fan, which in turn move air and create a draft. The amount of airflow is determined by the speed of the motor and the size of the blades.

DC Fans are used in a variety of applications including computers, servers, automotive and medical equipment. They offer many benefits such as low noise, high efficiency, and good ventilation in cramped conditions. Additionally, they require less maintenance compared to other types of fans as they don\'t require oiling or greasing.

In summary, the 17000B12A DC fan is a popular type of fan used in cooling applications. It has a brushless motor which makes it efficient, quiet and requires less maintenance. The fan operates on the principle of a static magnetic field which is used to attract and repel an armature, which in turn turns the fan blades and creates a draft of air. The amount of airflow is dependent on the speed of the motor and the size of the blades. DC fans are used in a variety of applications and provide benefits such as low noise, high efficiency and good ventilation in cramped conditions.
