Structure:
cantilever, bearingless, the fan impeller is directly mounted on the motor shaft, the speed of the fan is the same as the speed of the motor.
Advantages:
simple structure, compact, small fan volume, high mechanical efficiency fan.
Disadvantages:
fan size is small, can not meet the requirements of large air volume or high pressure.
Main application:
due to the bearing capacity of motor or affected by medium (such as high temperature), only suitable for medium without special requirements of small fans.
