Ventilation and heat dissipation

1. The ambient temperature is too high, so the inlet air temperature is high.

2. There are debris in the air inlet to block the air, which makes the air intake small.

3. Excessive dust inside the motor affects heat dissipation.

4. The fan is damaged or reversed, resulting in no wind or small air volume.

5, no windshield or motor end cover is not equipped with windshield, resulting in no motor wind path.
