Shell-type fans with external rotor motors – AFB0712VH-AF00

DC fans are compact, reliable, and quite energy-efficient cooling solutions. The AFB0712VH-AF00 DC fan falls into this category, with some extra features that make it a particularly attractive choice. This fan is a shell-type model with an external rotor motor and ball bearings. Let’s take a look at the application of this fan and learn about its working principle.

Application field

The AFB0712VH-AF00 is employed in many different applications. It is particularly popular in the telecommunications, automotive, and HVAC industries. Its design, parameters, and features make it suitable for use in air conditioning systems, radiators, switches, and UPS equipment. It’s also one of the best solutions for equipment for medical systems, medical equipment, and even instrumentation applications.

Design

This model of DC fan has a unique rotating exterior design that makes it especially attractive in many applications. It features an external rotor motor with a special fan impeller that generates the airflow. This design reduces annoying motor humming noise and ensures efficient cooling performance.The fan also features a thermal switch and air-permeable plastic housing. The casing is made of sturdy, flame-retardant plastic with an IP54 rating, making it suitable for installation in moist areas. This fan exhibits minimal vibrations and a long lasting lifetime. It can operate for up to 40,000 hours without suffering any wear and tear.

Working principle

The working principle of the AFB0712VH-AF00 fan is based on the external rotor motor that uses magnetic fields to generate an airflow. The external rotor motor consists of two parts: the stator, which is fixed to the plastic housing, and the rotor, which is connected to the fan blade and attached to an external shaft. When the rotor turns, it produces air pressure that drives the airflow through the fan blades.The magnetic field in the air gap between the stator and the rotor increases with increasing current. This causes the rotor to rotate at a faster speed and generate stronger airflow. The speed is controlled by adjusting the power voltage of the motor. The external rotor design helps reduce the electrical noise, provides efficient performance and makes the fan quieter.

Summing up

The AFB0712VH-AF00 DC fan is a reliable and energy efficient solution for many applications. It features a shell-type design with an external rotor motor that produces a powerful airflow. This fan also has a thermal switch and a flame-retardant plastic housing with an IP54 rating. It enjoys many features, such as minimal vibrations, a long lasting lifetime, and efficient performance that make it a popular choice for many applications.
