What is an external rotor fan ?

Traditional electric motors have a stator outside and the rotor rotates to generate power. The outer rotor motor has the opposite structure, with the stator in the middle of the motor and the rotor outside. The outer rotor fan adopts the advanced structure and reasonable aerodynamic design of the impeller directly driven by the outer rotor motor, and has the characteristics of high efficiency, low noise, light weight, compact structure, convenient installation and maintenance.AC Forward Curved Centrifugal Fans company
Introduction:
The rotor and the blades of the outer rotor fan rotate outside the stator. It has the advantages of compact structure, space saving, and exquisite design. The 100% variable-speed external rotor motor has a small starting current, the motor's protection level can reach IP54, the insulation level can be selected from B and F, and the motor has a thermal protector inside. The fan can run between ambient temperature -30 ℃ -60 ℃.
