Feb 13,2023
The external rotor fan adopts the advanced structure and reasonable pneumatic design of the impeller driven directly by the external rotor motor. 
It has the advantages of high efficiency, low noise, light weight, compact structure and convenient installation and maintenance.

The inner rotor fan is a set of spindle or motor formed by the core and coil. When energized, the inner rotor fan of AC works through the magnetic 
field generated by the starting copper block in the motor. DC fans are driven by Hall IC to generate magnetic field and rotate. Generally, DC fans are internal rotating structure, AC fans are mostly inner rotor blades, and the outer rotor blades are basically metal and iron blades.

Which Equipment are External Rotor Axial Fans used in ?
