The cooling fan is a commonly used cooling device in our daily life and can be seen everywhere in various mechanical equipment. The following is a test method for the cooling fan startup by Sanju Motor:

1. Starting voltage: The voltage that can start the DC fan after turning the switch "ON"

2. Locking current: The fan can be locked. The locking current is measured by locking the machine in fresh air for 3 minutes.

3. Noise standard: The noise standard test refers to DIN45635 standard. The measurement is carried out in a soundproof room, and the microphone is placed one meter away from the DC fan.

4. The air flow data and pressure data are measured according to the "AMCA standard" or DIN24163 rules. The data is measured in a double pressure chamber, and the pressure data on each side of the pressure chamber must be measured.

5. Rotation speed: The speed is measured after 3 minutes of continuous rotation.

6. Current: The current is measured after 3 minutes of continuous rotation.

7. Input power: Input power is measured after 3 minutes of continuous rotation.
