Guided by the design characteristics of electric fan blades, the writer proposes a method of revision through true measurements on the basis of the design procedures of equivalent axial fans.
Due to the strong axial and radial load to the bearing of electromotor in counter-rotating axial fan, it is always occurred that the bearing was damaged in use.
The objective of this paper is to build a software for axial fans' impeller designing.
OFEN Electric Company, is a modern enterprise which mainly produces mechanical and electrical integrated products, such as external rotor motor, centrifugal fan, axial fan, circular duct fans , etc.
The large axial fan with exterior drive motor draws the air out of the space.
