Ⅰ. What is a vacuum tester

Motor vacuum testing is a method used to check the sealing performance of motors.

In the motor manufacturing process, a relatively closed environment is usually formed inside the motor to ensure that the motor is not subject to external interference during operation. The motor vacuum test reduces the ambient air pressure by placing the motor in a vacuum chamber to observe any airtightness problem in the motor. It can ensure that the motor is not disturbed by moisture, dust, and other external environment when working, and improve the reliability and service life of the motor.

AIP, a company specializing in customized motor test equipment, provides motor stator vacuum testers that accurately and efficiently test the sealing of motor stators to ensure their reliability and safety in a variety of environments.

Ⅱ. the conditions under which a vacuum test of the motor stator is required

1. High-temperature conditions: Motor stators may face oxidation, evaporation, or volatilization when operating in high-temperature environments. Vacuum testing can reduce the rate of evaporation and volatilization and protect the motor stator by reducing the ambient air pressure.

2. High altitude environment: When using motors at high altitude, due to lower air pressure and thin air, the heat dissipation ability will be reduced, which will easily lead to overheating of the motor. Vacuum testing can improve the cooling effect of the motor and reduce the risk of overheating.

3. High-humidity environment: When the motor stator is operated in a high-humidity environment, it may be exposed to moisture and water, resulting in a loss of insulation or even a short circuit. Vacuum testing can expel moisture from the stator to ensure the normal operation of the motor.

4. Special applications: some special applications, such as aerospace, nuclear industry, and other fields, have very high requirements for motors and need to verify the reliability and safety of motors through vacuum testing.

Vacuum testing can help verify the ability of motor stators to withstand special environments and provide more reliable and stable motor performance. However, the specific need for vacuum testing is determined by the specific environment and requirements of the motor.

Ⅲ. How to perform a motor vacuum test

In motor vacuum testing, the motor to be tested is first placed in a vacuum chamber, and then the air pressure in the chamber is gradually reduced by extracting a vacuum pump. During this process, professionals will monitor the changes in air pressure inside and outside the motor, and use testing equipment to record and analyze the data. The motor vacuum test can determine whether the sealing performance of the motor is qualified. If the sealing performance of the motor is good, after the vacuum test, the change of air pressure inside and outside the motor should be very small, indicating that the motor has good sealing and no air leakage. If there is an air leakage problem, according to the test results can determine the location of the air leakage and carry out the corresponding repair treatment.
