What are the characteristics of the external rotor fan? What are the advantages and disadvantages? How to adjust the speed?

What are the characteristics of the outer rotor fan? What are the advantages and disadvantages? How to speed? Let's take a look at the relevant content. The external rotor fan is of reverse structure, the stator is in the middle of the motor, and the rotor is outside the motor. The outer rotor fan adopts the advanced structure and reasonable aerodynamic design of the outer rotor motor directly driving the impeller. It has the characteristics of high efficiency, low noise, light weight, compact structure, and convenient installation and maintenance.
