12V brush DC motor from Long Bo HY61021 oil pump brush motor W-8990

The testing process and requirements of DC motors before leaving the factory are as follows:

1. Electrical testing: the motor should be tested for insulation resistance, resistance, voltage, current and speed to ensure that the motor can operate normally.

2. Operating temperature testing: the motor should undergo a running test under different temperature conditions to ensure it can operate within the specified temperature range.

3. Load testing: the motor should undergo a load test to verify its torque, speed, and current characteristics to ensure it can operate under varying loads.

4. Noise testing: the motor should be tested for noise levels to ensure that it meets the designated limits.

5. Vibration testing: the motor should undergo a vibration test to ensure that it does not produce excessive vibration during normal operation.

In addition, each motor must pass a final inspection to ensure that it meets the required specifications and quality standards.

As a valued international customer, we would like to assure you that our DC motors are tested rigorously before leaving our factory to ensure they meet the highest quality and safety standards.
