AI Technical Summary
When the permanent magnet direct drive torque motor's fan cover is not running, it is open to the outside world, making it easy for foreign objects to enter and affect the fan's operation; when running, foreign objects come into contact with the fan, causing them to enter the fan cover.
A cooperative structure consisting of a fan cover, a protective baffle, and a limiting ring was designed. The pushing and pulling action of the limiting ring enables the protective baffle to be positioned, blocking the opening and preventing foreign objects from entering the fan cover.
It effectively prevents foreign objects from entering the fan cover through the ventilation mesh, ensuring the normal operation of the motor, protecting the fan structure, and extending its service life.
