What are the functions of motor fan blades and covers?

The motor itself generates heat when running, and the motor has a temperature protection function. It cannot continue to work after exceeding a certain high temperature. Fans are therefore necessary to dissipate heat. The fan circuit is usually connected to the motor and operates at the same time as the motor. When the motor is running, the fan is also running at the same time. The motor may cause the fan blades to rotate. causes airflow in even directions, and the cover also has a guard to prevent this. The personnel prevent foreign objects from entering the leaves to prevent foreign objects from affecting the work. The motor drives the rotation of the leaves, and the rotation of the leaves causes an air flow, forming an air flow, which is guided by the cover to form a regular direction that the persons can use. The cover also has a protective effect.
