Description

Technical Field

[0001] The utility model relates to the field of fans, and more particularly to an industrial fan. Background Art

[0002] There are many types of industrial fans, such as ceiling fans, axial fans, etc. An axial fan refers to a structure where there are mounting holes in a frame, and the fan blades are installed in the mounting holes and can rotate in the mounting holes. There are also brackets fixedly installed in the mounting holes, with the motor placed in the center of the bracket, and the motor drives the fan blades to rotate, thereby generating wind. However, this type of axial fan with the motor placed in the mounting hole has a complex structure and complex assembly on the one hand. This is because sufficient strength is required to firmly install the motor in the mounting hole. On the other hand, the strength of the bracket actually restricts the diameter of the fan blades, making it impossible to make this type of axial fan larger. Summary of the Invention
