Motor fan housing seat with stable structure

By adding upper and lower mounting parts to the motor fan cover base and changing the screw installation direction, combined with the positioning structure of the aluminum casting, the problem of screw loosening due to magnetic field was solved, thus achieving structural stability and reliability of the motor and its installation. This also resolved the screw loosening problem, improved the motor's structural stability and application, and addressed the technical issues related to the motor's application, ultimately ensuring stable motor operation.

AI Technical Summary

Technical Problem

The screws on traditional motor fan housings are prone to loosening due to magnetic field forces, leading to unstable motor operation and potentially causing short circuits or spindle jamming.

Method used

A stable motor fan cover holder was designed. By adding upper and lower mounting parts to the top cover and base, the installation direction of the screws is changed so that the screw nuts face the fan blades. Combined with the inner and outer stop structure and coaxial positioning structure of the aluminum casting, the screws are reliably tightened, thus improving the stability of the fan cover holder.

Benefits of technology

It effectively prevents screws from loosening due to magnetic field forces, ensuring the structural stability and reliability of the motor, avoiding unstable motor operation and potential failures, and meeting lightweight design requirements.
