The factory testing of the motor is an important part of ensuring the performance and quality of the motor. The following are the main contents of the motor factory test:
1. Appearance inspection: check whether the appearance of the motor is intact, no damage, rust, etc., and whether the identification and parameters of the motor are clear and accurate.
2. Dimensional measurement: measure whether the size of the motor meets the design requirements, including the size of the stator, rotor, bearing and other components and the size of the fit between each other.
3. Weight and center of gravity position measurement: measure the weight of the motor, and determine the position of the center of gravity of the motor to ensure the stability of the motor during installation and the balance during operation.
4. Insulation resistance test: test the insulation resistance of the motor to ensure that the motor has good insulation performance and prevent leakage, short circuit and other phenomena.
5. Withstand voltage test: The withstand voltage test of the motor is carried out to check the insulation performance and electrical performance of the motor under high voltage.
6. No-load test: install the motor on the test bench and test the running performance of the motor in the no-load state, including speed, current, voltage, power factor and other parameters.
7. Load test: Load test on the motor to test the performance indicators such as overload capacity, efficiency, and temperature rise of the motor.
8. Vibration and noise test: test the vibration and noise level of the motor to ensure the stability and comfort of the motor during operation.
9. Thermal test: Thermal test is carried out on the motor to test the temperature rise and heat dissipation performance of the motor under the condition of continuous work and overload.
10. Life test: Conduct a life test on the motor, simulate the actual operation of the motor, and test the life and reliability of the motor.
The above is the main content of the motor factory test, which can ensure that the motor performance and quality meet the design requirements, and provide a reliable guarantee for the customer's production and application.
