AC External Rotor Axial Fan
The YWF outer rotor axial flow fan blades are directly welded on the outer rotor, and the rotor and the fan blades rotate outside the stator, which has the advantages of compact structure, reliable operation, energy saving and high efficiency.
Introduction
AC External Rotor Axial Fan, also known as a local fan, is a fan with gas flowing parallel to the fan shaft, which is commonly used by industrial and mining enterprises. Unlike ordinary fans, the motor and fan blades of this product are in a cylinder, and the shape is a cylinder, which is very suitable for local ventilation. At the same time, it is often used in metallurgy, the chemical industry, food, medicine, and other industries because of its convenient installation, obvious ventilation effect, and the ability to send the wind to the designated area. In addition, it can also be connected in series at intervals in a long exhaust pipe to improve the wind pressure in the pipe.
Features
The overall structure of an AC External Rotor Axial Fan is relatively simple compared with other fans, so when we use this equipment, we can achieve normal operation with simple installation and operation. At the same time, the fan will not make too much noise during operation, so it will not have a huge impact on the surrounding environment. The fan is composed of blades, an outer rotor motor, a mesh cover, leads, etc. Through structural finite element calculation, modal analysis, and other methods, we ensure that our product structure is stable and reliable, with high safety factors, small vibration, and strong anti-interference ability.
