AI Technical Summary
The heat dissipation structure of the existing speed reduction servo motors causes dust to cover the motor surface when the air flows, resulting in a decrease in the contact area between the air and the motor surface, and dust needs to be cleaned frequently. However, the motor is set inside the shell, so it is very troublesome to open the shell for cleaning.
A heat dissipation structure including a rotating mechanism and a swing mechanism is designed. The rotating mechanism is driven to reciprocate back and forth and swing left and right through the rotating mechanism, so as to push the dust on the surface of the motor to avoid dust being stuck.
It enables the cleaning of dust on the motor surface without opening the housing, simplifies the cleaning process and avoids the reduction in heat dissipation efficiency caused by dust coverage.
